Erica Synths Drum Mixer Cheat Sheet
Overview:
The Erica Synths Drum Mixer is a 6-channel audio module designed for summing drum voices in a modular system. Key features include channel compression, effect send/return, and dual outputs.
Inputs / Outputs Reference
| Jack |
Function |
Notes / Voltage Ranges |
IN1–IN7 |
Audio Inputs (channel 1–7) |
±5Vpp max, input signal is muted when potentiometer is fully CCW |
AUX OUT |
Post-fader / post-comp send output for effects loop |
Audio signal out |
AUX IN |
Effects return input |
Audio signal in |
MAIN OUT |
Main summed audio output (post compressor & effects) |
Audio signal out |
Knobs / Controls Reference
| Control |
Type |
Function |
Notes |
IN1–IN7 |
Potentiometer |
Controls input level for corresponding input |
Sets gain, provides visual feedback via LEDs, up to ±5Vpp |
COMP AMT |
Potentiometer |
Amount of compression applied |
Adjusts signal compression to taste |
RELEASE |
Potentiometer |
Compression release time |
Sets the release time for compressor |
SWITCHES |
Toggle switches |
Routes each input to Main output and/or Aux Send |
Assigns each channel's signal to main or auxiliary outputs |
LEDs
- Channel LEDs: Show visual feedback for input signal level (illuminated when signal reaches ±5Vpp).
- Clip LED: Indicates when signal level exceeds headroom, risk of distortion.
Signal Routing Tips
- Channel Assign: Use switches per input channel to route to Main output, Aux Send, or both.
- Compression: Use COMP AMT and RELEASE to dial in dynamic control across summed channels.
- Effects Loop: Patch from AUX OUT to external FX, return to AUX IN. Only channels routed to Aux Send are sent to this path.
Tech Specs
- Mixer Gain: Adjustable per channel
- Max Input Level: 10V peak-to-peak
- Headroom: >20Vpp
- Depth: 35mm
Quick/Typical Workflow
- Patch drum/audio sources to
IN1–IN7.
- Set channel levels with each channel's potentiometer.
- Assign outputs for each channel with toggle switches (Main, Aux, or both).
- Optionally compress the mix with COMP AMT and RELEASE.
- Apply FX: Send to external FX via AUX OUT and return processed audio via AUX IN.
- Monitor the main mix from
MAIN OUT.
