For more information, see the “Aux Input (Bluetooth)” section.

5.3 Left Side Panel


You can use the two DUAL HEADPHONE 3.5 mm mini TRS outputs to connect two separate headphones to ENDGAME.

These dual outputs allow to you share your completed mix with another musician, or you can use for IEM (In Ear Monitoring), either wired or via a stereo wireless IEM system.

The level knob between the two DUAL HEADPHONE outputs adjusts the volume of both outputs simultaneously.


Connect two XLR connectors to the FULLY BALANCED OUTPUT jacks to send the ENDGAME’s stereo main mix (Left/Right) to the Front-of-House/PA system, to FRFR cabinets, a recording system etc.

Use the XLR OUTPUT LEVEL control to adjust the output level from Mic Level/-60 dBu (Fully left / counter-clockwise position) all the way up to professional +4 dBu (Fully right / clockwise position).

To help alleviate situations where you may encounter hum, the internal Ground Lift can assist when connecting to other devices or if you encounter grounding loops etc.

If the GND LIFT switch is depressed, Ground Lift is activated.

19 – TS/TRS LINE OUT Jacks

The two TS/TRS LINE OUT jacks output ENDGAME’s complete Stereo Main Mix (Left/Right) at Line Level.

5.4 Right Side Panel

20 – INPUTJack

Connect the last mono device in your signal chain to the 6.35 mm INPUT jack. This is typically your preamp, modulation pedal, mono cab sim etc. or your source instrument (guitar, bass or other).

21 – INPUT GAIN Control

The INPUT GAIN control with its premium high impedance circuitry can provide up to +/-24 dB of gain/reduction.

Use the INPUT GAIN control to reduce the gain if the red INPUT CLIP LED (11) is illuminated.

For more information, see the “Setting Levels” section.

22 – THRU Jack

The THRU jack outputs the INPUT signal in parallel.

This extra connection is useful for a multitude of situations e.g. for an amp, tuner output, separate channel etc. or for recording the dry unprocessed signal into a DAW for post processing.

23 – POWER AMP MODE button

The POWER AMP MODE push button toggles between the three available Power Amp Models and Off/Bypass.

The colour of the front panel PWR AMP MODE LED indicates the currently selected Power Amp Simulation model.

For more information, see the “Power Amp Mode” section.

24 – STEREO FX LOOP Send/Return Jacks

Insert Stereo devices using the respective L (Left) and R (Right) jacks of the STEREO FX LOOP section. The FX Loop is enabled/disabled with the FX LOOP Foot Switch (8) on the front panel.

Use the TRUE DOUBLE TRACKING and DUAL IR CABINET SIMULATION toggles o set the PRE/POST position of the FX Loop within ENDGAME’s signal chain.

For more information, see the “Stereo FX Loop” section.

5.5 Internal DIP Switches

For extended monitoring flexibility, there are two mini–DIP switches within the ENDGAME to control various monitoring options.

These are located on ENDGAME’s main circuit board (PCB) as shown here:

ENDGAME Internal DIP Switches

Note: To access these DIP switches, remove the four screws that attach the rear plate to the main body of the pedal. Be extremely careful when opening the device and reattaching the plate as not to snag or disturb any cables, components etc. on the various internal PCBs. Apart from these DIP switches, no other user serviceable parts are inside and any further adjustments to any other component inside may damage the product, which will void your warranty.

Switch 1 – AUX BYPASS

Switch 1 disables the AUX INPUT (Analog or Bluetooth) from being passed to the Main XLR/TRS Outputs.

This can be very useful for IEM and many other scenarios.

Switch 1 set to ON

The AUX IN signal is sent to the Headphone outputs and both the XLR and TRS outputs simultaneously.

Switch 1 set to OFF

The AUX IN signal is sent to the Headphone outputs only.

For more information, see the “In Ear Monitoring Magic” section.

Switch 2 – Impulse Response / Amp Simulation Bypass

Switch 2 disables Ambience, Cab Impulse Response and Power Amp Simulations from the TS/TRS Outputs. This is perfect for monitoring using regular guitar amps on stage while sending the full mix to IEM/Headphone and XLR Outputs.

Regardless of the position of Switch 2, the full mix is always sent to the Headphone Outputs.

Switch 2 set to ON

Ambience, Cab Impulse Response and Power Amp Simulations are sent to both the XLR and TS/TRS Outputs.

Switch 2 set to OFF

Ambience, Cab Impulse Response and Power Amp Simulations are sent to the XLR outputs only.

For more information, see the “Multi Monitoring” section.

6. Setting Levels

Stetting the optimum levels of any audio device, otherwise known as Gain Staging, will always give you the best overall experience. Within ENDGAME, the main INPUT GAIN control with its premium high impedance circuitry can provide up to +/-24 dB of gain/reduction.

When setting up your external gear with ENDGAME, it is advisable to take some time to ensure that volume levels for each device in your signal chain are set up correctly.

With the FX Loop turned off, start by establishing a correct level at the input, using the INPUT GAIN control. make sure that your loudest possible input signal (from e.g. Distortion, Overdrive, Fuzz, Octave, Synth, Boost, Compressor or any other device before the main input) is not causing the red INPUT CLIP LED to illuminate. If the INPUT CLIP LED does light up, reduce the INPUT GAIN control until the LED is no longer active.

Following this procedure, enable the FX Loop and then work to ensure that your Stereo effects in their loudest settings are also not causing the INPUT CLIP LED to illuminate. Some stereo effect units can add gain to signals, dependent on the effect used and their individual settings.

Essentially the goal is to ensure that gain staging is set for optimal usage of all devices within the signal chain, to get the best out of them and your rig.

7. Stereo True Double Tracking Doubler

Doubling guitars is a common practice in a wide variety of musical genres. In the majority of cases, a single guitarist will record the same (mono) track twice, with one track being panned to the left channel and the other to the right channel. The effect of this is unmistakable to the ear and the slight differences and nuances between the two separate performances complement each other, helping to create a noticeable thickness, density and weight to the musical experience.

Please be aware that this effect is not the same as simple doublers (that just delay one side of the signal and introduce modulation) or other ADT type solutions that are available on the market today. KMA has carried out extensive research on how to make double tracking sound exactly how we believe it should perform. We’ve spent thousands of man hours developing our own proprietary solution, even designing our own custom neural network AI with onset detection in the process.

Enabled via the footswitch, KMA’s True Double Tracking Doubler accurately replicates the minor differences that could exist within two separate recordings and the width can spread your doubled tracks anywhere from completely centred to 50% left and right and 100% left and right split.

7.1 WIDTH Control

Although we give the option to narrow or widen the effect with the TDT WIDTH control, we think that most players will opt to keep it at 100%. This will give the best emulation of authentic double tracking. While many may prefer to continue going through this process authentically during the recording process, ENDGAME allows this highly impactful effect to be replicated both live and during practice, maximising audible impact as well as fuelling creative inspiration.

Besides the 100% WIDTH setting, other areas within the range of this control increase your creative options, with the doubler becoming a very useable and unique effect in a range of musical contexts.

To set the WIDTH, turn the control as follows:


While for the most accurate performance (and just like in a real studio double tracking scenario in the studio), our custom True Double Tracker algorithm should ideally be fed with a mono signal.

In other words, this should be before the Stereo FX Loop, thus setting the Toggle on the front panel to PRE – see 9.1 FX LOOP POSITION. Having said that, our TDT algorithm has been optimised to still have a useful and very pleasing widening effect on stereo signals, so see what works best for your tonal preferences.

8. Dual Cabinet Impulse Response, Power Amp Simulation and Ambience

The built-in Dual Cab Sim Impulse Response Loader is KMA’s own simple, yet flexible and unassumingly powerful convolution cabinet simulation solution, designed to suit a multitude of musical circumstances. For this, we developed a new technology we call “Dynamic Responsive Onset AI Convolution” or DROAC™ for short.

Many other devices on the market today can potentially lead you down the path of option paralysis, so we decided to just keep ENDGAME intuitive and immediate. Our aim is to help you focus on creating rather than constantly adjusting, as in our experience once you’ve found your ideal cabinet tones, it’s generally preferable to stick with these favourites. However, unlike a number of alternatives out there, if you do want to experiment, we added an OFF mode. This means you can still use your existing favourite of the plethora of great simulation devices that are available, while still experiencing the unique and super useful ENDGAME features – the choice is yours!

The 3 main onboard presets are based on KMA’s own choices and are based on popular, standard examples that will fit a majority of situations. These Genuine Dynamic Impulse Responses are powered by industry leading speaker brand Celestion®, for the most authentic tone possible and curated specifically for their own “Magnificent 7 Collection”. Each included Impulse Response is a custom blend by Celestion®, created with the help of multi-platinum Engineer/Producer Mike Spink at Decoy Studios, a world class live room which is the professional home of award-winning mixing engineer Cenzo Townshend. All of the included Impulse Responses are a mix between 3 industry standard microphones (Royer R-121, Sennheiser MD421 and Shure SM57), optimised to either high or low gain settings.

Positions UA and UB are completely user definable. There are a multitude of third-party Impulse Responses out there which can be loaded into ENDGAME’s internal storage simply using a USB-C cable connected to your host device (see section 7.2)

Why “Dual”? Well as the ENDGAME is a stereo device, what goes into the Left side of the Cab Simulation stays in the Left output (and vice versa relating to the Right side). However, what if you desire a totally different speaker cab to the other on one side of your stereo signal? Well, we thought of that, as you can easily do this via the custom loader simply by placing different Impulse Responses in each corresponding folder. From the factory, we’ve pre-loaded these slots with examples/combinations of our various cabinet choices on each side, but loading your own Impulse Response cabinets in these user slots is a breeze!

In addition, the separately selectable Tube Power Amp Simulator and Ambience features add another sense of realism to polish up your tone.

8.1 CAB IR Selector

Using the CAB IR rotary switch on the front panel, you can quickly and easily select from 6 different Cabinet settings.

OFF setting

The Off setting completely bypasses the Impulse Response Loader allowing the ENDGAME to be used with a variety of other mono amp / cabinet simulators via the mono Input, Stereo FX Return or for processing other signals which don’t require cabinet simulation.

V30 setting

Use the V30 setting to simulate a 4x12 closed-back cabinet equipped with Vintage 30s, optimised for High Gain.

“A superbly versatile speaker that has found a home delivering a generous range of metal and rock tones with tight bass, rich and vocal mid-range and an intricately detailed top end. Clean tones are crisp and that famous upper midrange sits just right in the mix.”

GNBK setting

Use the GNBK setting to simulate a 4x12 closed-back cabinet equipped with Greenbacks, optimised for High Gain.

“The G12M-65 is a modern incarnation of the speaker that helped define rock tone; played by legends like Clapton, Page and Beck. Expect a broad mid-range attack and a restrained top-end with added grit and aggression”.

CMBK setting

Use the GMBK setting to simulate a 4x12 closed-back cabinet equipped with Creambacks, optimised for Low Gain.

“The G12H-75 is a speaker with added power and with a heavier magnet that enables the production of a tight bass with impactful highs, adding awesome thickness to single notes”.

UA setting (User Slot A)

ENDGAME has two storage slots for adding your own Impulse Responses. From the factory, User Slot A (U⋅A) is loaded with G12M-65 (Left) and V30 (Right).

UB setting (User Slot B)

From the factory, User Slot A (U⋅A) is loaded with G12H-75 (left) and G12M-65 (right).

The UA and UBslots will default to the factory settings when no other Impulse Responses are present in the respective mass storage device’s folder structure. For more information, see the “Impulse Response Loading” section.

8.2 Impulse Response Loading

Third-party Impulse Responses can be loaded into the ENDGAME’s User Slots via the USB-C connector. These Impulse Responses can then be accessed using the UA and UB positions on the CAB IR rotary control.

To load your own choice of IRs into these User Slots, all you require is a Mac (running macOS 10.13 or later) or a PC (running Windows 10 or later) and a relevant cable to connect ENDGAME to your computer.

Please follow this procedure to load Impulse Responses into the ENDGAME’s User Slots:

  1. Connect the ENDGAME to your Mac or PC using a standard USB-C cable.
  2. The ENDGAME should appear on your host device as a mass storage device (external drive etc).
  3. Simply drag and drop the required Impulse Response file into the relevant folder.
    The folder structure denotes Left and Right within UA and UB. Drag and Drop either the same Impulse Response file into both the Left and Right folders or use different Impulse Responses for Left and Right if so desired.
  4. When no Impulse Response exists in a folder, the ENDGAME will load the factory preset Impulse Responses by default.

While the ENDGAME is a plug and play class compliant USB device, we highly recommend that you unmount (Mac)/ Eject (Windows) the mass storage device/drive before unplugging it from your computer. This will help to prevent any connection errors when reconnecting.

Note: ENDGAME’s architecture currently allows for .wav Impulse Response files specified up to a maximum of 48 kHz / 500 ms. Any lower sample rate or length will be upscaled as part of the convolution loading process.

8.3 Power Amp Mode

Power amps can make a fundamental difference to your tone. ENDGAME’s integrated Tube Power Amp Simulator is designed to replicate the overall tonal characteristics of the most common type of tube amps to give the “right” amount of sag and compression.

Simply push the POWER AMP MODE button on the right-hand side of the pedal to toggle between the 3 Power Amp Models and Bypassed.

The colour of the front panel PWR AMP MODE LED pedal indicates what mode is selected:


EL34 selected


6L6 selected


KT88 selected

PWR AMP MODE LED Blank/unlit


Note: ENDGAME’s Tube Power Amp Simulator always comes before the Dual Cab Impulse Response in the signal flow. For more information, see the “Internal Signal Routing” section.

8.4 Ambience

We have added a simple yet effective Ambience feature to the Impulse Response section.

With some Impulse Responses (IR), the feel you can get is that the tone not as lifelike as it could be. This often becomes even more prominent when using headphones, where it can seem like the captured virtual cabinet is almost right inside the centre of your head. The Ambience control allows you to simply adjust the level of natural room ambience to counteract this effect.

Essentially, it’s a little like having an extra couple of microphones to capture the reflections from the room in which the virtual cabinet is placed – just like many creative studio engineers have done on countless classic recordings. Variable from completely dry/off, adding a sense of space that’s suitable for most styles of playing and right up to a larger expanse, this feature will help to set the size of the stage for your tone.

To set the Ambience level, turn the control as follows:

AMBIENCE control fully counter-clockwise / left

Ambience is Off (dry signal).

AMBIENCE control at centre indent (12 o’clock position)

Ambience that is representative of a medium-sized room.

AMBIENCE control fully clockwise / right

A lush and even more spacious effect.

Note: ENDGAME’s Ambience always comes after the Dual Cab Impulse Response in the signal flow. For more information, see the “Internal Signal Routing” section.

9. Stereo FX Loop

Integrating stereo effects into your signal chain is a common challenge for many guitarists. Without the luxury of 2 amplifiers (or the ability to turn them up if you have them) or for owners of cabinets simulators that are usually mono by design, ENDGAME offers an easy to integrate and distinctive solution to this challenge.

For the sake of long cable runs and to maximise signal clarity, ENDGAME’s serial Stereo FX Loop is buffered. This means you can now hear your stereo pedals and other effects in their true pristine glory.

Connect the Left and Right Sends on the (Right Panel) to the Left and Right Inputs on your stereo device and connect the Left and Right Returns on ENDGAME to the Left and Right Outputs on your stereo device.

You can quickly switch the loop on or off via the convenient soft footswitch.

9.1 FX Loop Position

When the FX LOOP is activated, the two switches on the front panel change the signal routing.

For the ultimate in creative flexibility, the entire CAB Impulse Response Loader, Power Amp Simulation and Ambience block can be positioned pre or post FX Loop using the DUAL IR CABINET SIMULATION PRE/POST toggle switch. In addition, the same flexibility is available for the True Double Tracker circuit using the TRUE DOUBLE TRACKING toggle switch.

For example, many audio engineers traditionally apply stereo effects (usually reverb and delay) after the cabinet in the recording signal chain so the clarity of the effects can be achieved as cleanly as possible. This is even more the case when using double tracking etc. so that the carefully constructed doubled extra weight you have added to your tone doesn’t turn into mush.

However it all depends on your tonal desires – which is why we gave the flexibility here for different connection scenarios- Choose what sounds best to you!

To see the routing in detail, check out the signal flow diagram in the “Internal Signal Routing” section.

10. Aux Connectivity

Placed directly before the Main Outputs in the signal flow, the AUX INPUT is an excellent solution for feeding a backing track or any other stereo signal into the outputs of the ENDGAME and making it perfect for many purposes, including practicing.

In addition to the analog mini stereo 3.5mm jack, we have added a Bluetooth® connection for audio streaming. This means you can hook up many of today’s devices – such as phones, tablets, computers and the like – to use ENDGAME’s high quality XLR, TS/TRS and Dual Headphone outputs for playing music and more.

10.1 Aux Input (Mini TRS)

To connect an auxiliary audio device to ENDGAME (for the purpose of baking tracks, instruments such as drum machines or any other external audio device monitoring), proceed as follows:

  1. Connect the stereo output of your device to ENDGAME’s AUX IN 3.5 mm Mini TRS input.
    Your device should now be able to play audio through the respective outputs of the ENDGAME.
  2. Adjust the AUX MIX control on the top panel to adjust/blend the external audio level in balance to ENDGAME’s signal. For more information, see the “Aux Mix” section.
    Please ensure that your external device is providing sufficient level to the ENDGAME before adjusting the control.

10.2 Aux Input (Bluetooth)

To activate Bluetooth® Pairing Mode and connect a device to stream audio to ENDGAME, proceed as follows:

  1. Press the BT PAIR button on the ENDGAME for approximately 4 seconds until the BT LINK LED on the front panel flashes.
  2. In your device’s Bluetooth® audio paring settings, choose “KMA ENDGAME” as the device.
    The BT LINK LED will turn solid once a connection has been established.
    Your device should now be able to stream Bluetooth audio through the relevant outputs of the ENDGAME*.
  3. Adjust the AUX MIX control on the top panel to adjust/blend the external audio level in balance to ENDGAME’s signal.
    For more information, see the “Aux Mix” section.
    Please ensure that your external device is providing sufficient level to the ENDGAME before adjusting the control.

Note: An active paired Bluetooth® connection will override any analog device connected to the AUX IN. To disconnect and unpair your Bluetooth device, push and hold the BT PAIR button until the BT LINK LED is no longer illuminated.

As with all Bluetooth® devices, any audio connections using this connection method will add latency/delay to the signal. This is of no consequence for static backing tracks, recorded music and the like. However, for real-time audio signals that should be processed without latency, we suggest that you use the regular analog AUX IN jack.

10.3 Aux Mix

To set the levels/balance of your selected auxiliary source, adjust the AUX MIX control as follows:

AUX MIX control fully counter-clockwise / left

ENDGAME’s internal signal is 100% and the AUX signal is muted.

AUX MIX control at centre indent (12 o’clock position)

ENDGAME’s internal signal and the AUX signal are 50/50 equal.

AUX MIX control fully clockwise / right

The AUX signal is 100% and ENDGAME’s internal signal is muted.

Which outputs are active depends on ENDGAME’s Internal Dip Switch settings. For more information, see “Switch 1 – AUX BYPASS” in the “Internal DIP Switches” section.

11. ENDGAME Setup Suggestions

ENDGAME has been engineered to work in a huge variety of setup scenarios.

There is a massive amount of all sorts of excellent effects out there, so it pays to experiment in your pedal order to achieve your exact tonal requirements and how to best assemble your dream rig. There is no right or wrong way. However, the following setup examples should help get you started and help you to achieve a great sound as fast as possible.

11.1 Dream Fly Rig

KMA ENDGAME Setup example: Dream Fly Rig
  1. Connect your instrument to your favourite drive and other mono pedals, then choose your preamp of choice from the multitude of great examples available on the market today and connect that into the input socket.
  2. Use ENDGAME’s built in Cabinet Simulations (or your own user defined Impulse Responses) with ENDGAME’s Power AMP Simulation and connect that directly to the PA.
  3. Add some stereo effects in the Stereo FX Loop and you have a complete portable solution which can be highly flexible and with a feature set beyond the capabilities of many heavy combos, amplifiers and cabinets.

Tone Tip: Many mono preamps also can have cabinet and power amp simulation built in. If your device provides the option to turn on / off their internal cab and power amp modelling etc., this can give you the additional option of using these or the options within ENDGAME. Remember though that if you do use external cab and power amp simulation, for the best results you will need to ensure that these options are turned off on ENDGAME, in order that you are not duplicating the simulations. For this setup, we also recommend that both FX Loop Position toggles switches are set to PRE.

11.2 Potential Maximiser

KMA ENDGAME Setup example: Potential Maximiser

There are several Amp Modellers/ Cabinet Simulators on the market that are highly detailed products with extensive options which are highly customisable via their user interfaces.

Depending on your own personal preference, you can decide whether to use the Celestion® Cabinet Impulse Responses that are included in ENDGAME or use your preferred existing simulation device. In that case, run your device into the ENDGAME’s input.

This allows you to use all of the secondary device’s features, while the ENDGAME compliments these with a more comprehensive set of IO, the TDT Stereo Doubler, the ability to add stereo effects via the FX loop, Bluetooth, Dual Headphone outputs or all of these at once.

Tone Tip: Traditionally, stereo effects are often added after the guitar preamp, power amp and speaker when mixing or recording. Sending a “finished” mono signal into the ENDGAME enables you to create a virtual “mix bus” on your pedal board by adding doubling, then stereo effects to this setup and complimenting it in the same way as an engineer may do when mixing a recorded guitar “group”. Remember though that if you do use external cab and power amp simulation, for the best results you will need to ensure that these options are turned off on ENDGAME, in order that you are not duplicating the simulations. For this setup, we recommend that both FX LOOP POSITION toggles switches are set to PRE.

11.3 Stereo Input

KMA ENDGAME Setup example: Stereo Input

If you wish to connect a stereo device – such as a stereo Amp/Cab Sim or synth etc. – directly to ENDGAME, then you can connect these via the Stereo FX Loop return.

While this setup will negate the FX Loop, it still allows you to gain benefits from all the other ENDGAME features. This setup also compliments your device with a more comprehensive set of inputs and outputs, such as dual headphone outlets, Pro level XLR, separate TS/TRS connections, Bluetooth etc. And it will also turn the FX Loop footswitch into a single-press mute function.

Tone Tip: While for the most accurate performance our custom True Double Tracker algorithm should be fed with a mono signal, it still has a useful and very pleasing effect on stereo signals. In the majority of cases, Stereo effects are usually added after the guitar preamp, power amp and speaker when mixing or recording. However, note that if you wish to use a preferred Stereo Cab/Amp Sim device, most of these are fundamentally mono internally (only built in simple ambience or stereo input signals are processed to pass through in stereo), so we do suggest you experiment with running these kinds of devices in mono directly into the ENDGAME’s input and use the FX loop for your stereo pedals. This will allow you to get the best benefits and tonality that ENDGAME provides. For this setup, you need to make sure that both FX LOOP POSITION toggles switches are set to POST.

11.4 Rig Doubler

KMA ENDGAME Setup example: Rig Doubler

Utilising the ENDGAME’s ability to create a dual amp setup from a mono signal, try plugging your instrument into the ENDGAME directly. Then use the left and right channels of the loop for two separate and complete mono signal chains. These mono signal chains are then summed within the ENDGAME.

Adding different preamps or amp modellers in each channel can create interesting results, with the difference in each perceivably adding depth and aural distinction to your overall tone.  

Tone Tip: You can also use each side of the FX loop for creative endeavours with mono effects. Try experimenting by blending different mono delays, reverbs and modulations, creating virtually unlimited interesting and unique textures for each stereo side of ENDGAME’s output. For this setup, we also recommend that both FX LOOP POSITION toggles switches are set to PRE.

11.5 Multi Monitoring

KMA ENDGAME Setup example: Multi Monitoring

In a live scenario, instead of using In-Ear Monitoring or a wedge monitor mix, you may wish to use guitar combos or a stereo power amp rig with speaker cabinets so you can hear yourself.

Normally this would not be a great idea with any cab/amp simulator devices as this duplicates the purpose of the device. However, we gave an option to achieve just that.

By moving the second internal dip switch to the “OFF” position, the Impulse Response, Power Amp and Ambience sections of the ENDGAME are bypassed from the TS/TRS outputs. For more information, see the “Internal DIP Switches” section.

This allows you to use these connections for your amps, while the XLR outs send the full signal chain, including Impulse Response, Power Amp and Ambience to the Front of House or any other external monitoring system, all adding flexibility and maximising the potential of your on-stage setup.

Tone Tip: Rather than micing up cabs at a performance, taking the direct signal from the ENDGAME’s XLR outputs guarantees that your stereo tone arrives at the desk exactly the way you intend it to be heard. For this setup to function correctly, we recommend that the TRUE DOUBLE TRACKING toggle switch is set to PRE, while the DUAL IR CABINET SIMULATION toggle switch must be set to POST.

11.6 In Ear Monitoring Magic

KMA ENDGAME Setup example: In Ear Monitoring Magic

When using In Ear Monitors for your live monitoring, the mix for this is usually provided from the PA/Front-of-House mixer etc. via an Aux Mix/Send.

However, you may want more of your own level or have an easy and simple way to blend your own monitoring levels.

Many musicians can experience a slight delay between their own signal and what comes back from the monitor mix depending on the type of connections used and this is even more prevalent with many digital consoles. In addition, if there are not enough aux sends on your rig, sometimes you may not be able to hear yourself in stereo either.

So, by using the analog AUX input for your monitor mix in and the ENDGAME’s headphone out to your wired IEMs (or connected to your own IEMs wireless set up) you will have more direct control over your own levels. In this case though, you just need to set the relevant internal DIP switch to not pass the Aux input section to the Main Outputs (see Section 5.5 Internal DIP Switches) – no more debating with the engineer for “more me” – you have your own control!

Tone Tip:  If your Mixer’s dedicated Aux send is Mono, you will need to make a special 3.5 mm mini TRS cable where both left and right poles are “bridged” to both sides. We recommend that any Aux mix sent to ENDGAME has no guitar signal present, else you may experience strange effects like comb filtering etc. To set your ideal balance between the direct ENDGAME signal and your PA Aux feed, use the AUX MIX control to blend. For this setup, we recommend that both FX Loop position toggle switches on the ENSGAME are set to PRE.

12. Internal Signal Routing

KMA ENDGAME – internal signal routing

This diagram shows ENDGAME’s internal audio signal routing.

The position of the Stereo FX loop can be changed based on the settings of the two toggle switches on the front panel. For more information, see the “FX Loop Position” section.

13. Updating Firmware

While we have tested ENDGAME thoroughly, like with all complex digital devices we may seek to improve or even add new features to help you get the most out of your pedal. Consequently, there may be software updates issued in the future. These software updates can be loaded via the USB-C socket connected to a Mac or PC.

Exact details on when any new firmware is available and how to load these updates will be communicated via the KMA Machines website.

14. Factory Reset

In the event that you wish to return your ENDGAME to its original factory settings, proceed as follows:

  1. Disconnect Power.
  2. Make sure both FX Loop Position toggle switches are in the PRE position.
  3. Press and hold the DOUBLER footswitch and the PWR AMP MODE button.
  4. Reapply power to your ENDGAME, while continuing to hold these controls for a few seconds.

Note: Resetting the product to factory settings deletes any customised loaded Impulse Responses stored in the on-board User Memory Slots (UA and UB).
