CGM Master (M)
The Masterone is the gateway from the modular system to the outside world, providing high-quality outputs in multiple formats including pseudo-balanced stereo TRS, balanced stereo XLR, and pseudo-balanced mono outputs, plus a headphones/PFL section.599
Capabilities 5
- Audio Mixeraudio-mixer
- The Masterone receives the stereo mix bus from upstream CGM Channel and Group modules via the CGM Link bus and provides the final output stage.599
- CUE/PFL Monitoringcue-monitoring
- PFL circuit receives PFL signals from connected channels and groups; the PFL Blend knob crossfades between main mix and PFL signal in headphones output.599
- Headphone Outputheadphone-output
- Dedicated headphones section with independent level control (A.27) and PFL Blend crossfader (C.5) to blend main mix with PFL signal for cueing.599
- Mute-Grouped Mixermute-grouped
- CGM console master/monitor section: PFL blend, master and headphone outputs for the group/channel buses.

Jacks 6
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Outputs (6) | |||
| Balanced Output Left | audio | — | Balanced XLR stereo left output. Their output will sound twice as louder as the pseudo-balanced one (+6 dB). Attenuatable by 30 dB via Line/Mic switch.599 |
| Balanced Output Right | audio | — | Balanced XLR stereo right output. Their output will sound twice as louder as the pseudo-balanced one (+6 dB). Attenuatable by 30 dB via Line/Mic switch.599 |
| Master Output Left | audio | — | Pseudo-balanced ¼" TRS stereo left output at Eurorack line level. Attenuatable by ~15dB via Line/Inst switch.599 |
| Master Output Right | audio | — | Pseudo-balanced ¼" TRS stereo right output at Eurorack line level. Attenuatable by ~15dB via Line/Inst switch.599 |
| Mono Out | audio | — | Pseudo-balanced monophonic output providing the sum of left and right channels. Features an amplifying circuit with additional 6 dB of gain and 15 dB of attenuation from line level reference.599 |
| Phones Stereo Output | audio | — | Stereo headphones output jack with independent level control and PFL blend. The headphones level is independent of the main fader's level.599 |
Parameters 6
| Name | Type | Range | Behavior |
|---|---|---|---|
| Line/Inst Switch | switch | — | Attenuates the TRS pseudo-balanced stereo outputs by ~15 dB when set to lower position (Inst), to match instrument-level destinations.599 |
| Line/Mic Switch | switch | — | Attenuates the XLR balanced stereo outputs by 30 dB when set to lower position (Mic), to match microphone-level destinations.599 |
| Master Fader | fader | — | Sets the overall volume of the master output. Controls the amplitude of the sum of connected groups. The Master features two columns of 12 LEDs acting as a stereo VU meter.599 |
| Mono Out Fader | fader | — | Controls the mono output level. Rotate left to attenuate (up to -15 dB from line level), rotate right to amplify (up to +6 dB from line level).599 |
| PFL Blend | knob | — | Crossfader blending the main out signal with the PFL signal for headphone monitoring. Used to prelisten channels or groups before mixing them in.599 |
| Phones Level | knob | — | Sets the headphone output volume independently of the main fader.599 |
