Each of the 20 inputs features a 12 dB/oct HPF, noise gate, a compressor/de- esser (inputs 1-16 only), a flexible 4-band parametric EQ, and a delay line. The source can be selected between the analog input, the USB audio interface and the SD card player.

M 20X boast 4 stereo FX engines available on dedicated busses, offering two high quality digital reverbs, a programmable delay and a 4th effect which can be configurated as a modulation or a second delay. All FX Engines offer multiple algorithms to match the specific needs of a show.

A complete processing section is available on all outputs: a flexible 8-band parametric EQ with several selectable modes, that also allow different slopes, a delay with up to 85 meters compensation, a compressor/limiter. A stereo 30-band graphic equalizer is available on the MAIN outputs for precise correction of the overall frequency response. Extensive routing options allows flexible use of physical outputs.

SETUP

This section explains how to set up the M 20X digital mixer the first time you turn it on.

Configure Mixer Menu

Press the SYSTEM key, go to the UTILITIES > CONFIG MIXER page, and set the M 20X boot mode. If LAST STATUS is enabled, at power-up the M 20X will load all the settings available before turning off the unit. This is the preferred option. If LAST STATUS is disabled, the mixer will boot with the default initialization.

If you press and hold the FACTORY RESET button, you can reset the console to the default initialization, erasing the current show, every stored show and every stored preset.

If you want to initialize the console and maintain your saved shows, presets and global settings, press the SYSTEM key and on the page SHOW, hold pressed DEFAULT option.

A SHOW includes all parameters pertaining to inputs, outputs and IO Routing, except the global configuration parameters. For details on the Faders Calibration and Brightness adjustment, please refer to the Owner’s manual.

I/O Routing

The M 20X console offers versatile routing capabilities to easily manage all inputs and outputs, including the USB audio interface and the internal players and recorders.
Direct Patches are internal intermediate routing points that can be routed to multiple destinations.

To reset routing settings, go to the I/O ROUTING > ROUTING PRESET page, then press and hold the DEFAULT button. All routing options will be reset as detailed below.

Default INPUTS routing

Default REC OUTS routing (SD Card REC Channels)

Default STREAM OUTPUTS routing (USB audio interface upstreaming tracks)

Default OUTPUTS routing

Default DIRECT PATCH routing

For details on the I/O Routing options, please refer to the Reference Guide
