Mix And Monitor Your Rig With The 4ms Listen Four 4-Channel Stereo Mixer Module

The Listen Four is a four channel stereo mixer with line, modular, and headphone outputs. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.



  • Four input channels (two with stereo inputs, two with mono inputs and a Pan knob)
  • Headphone and main 1/8" outputs, each with separate Level knob
  • Line level output driver with zero impedance, capable of driving long cables
  • Output can be switched between line and modular level
  • Low noise, cross-talk, and bleed-through
  • Anti-pop feature that silences pops and thumps when the power is turned on
  • Headers in back allow for connecting to other Listen Four or Listen Four Quarters modules to create a mixer with 8, 12, 16, or more channels and multiple sub-mix outputs
  • Connects via headers to WAV Recorder module for recording final mix without using patch cables
  • Signal lights for each channel and output mix
  • Clipping lights with adjustable level


  • 10HP Eurorack format module
  • 0.98" (25mm) maximum depth (includes power cable)
  • 10-pin Eurorack power header

POWER CONSUMPTION

  • Maximum values without using headphones jack (Main outputs shorted to ground, headphones jack not used, maximum signal levels on all channels)
  • +12V: 70mA
  • -12V: 62mA
  • Maximum values in worst-case conditions (All outputs including headphone jack shorted to ground, maximum signal levels on all channels)
  • +12V: 200mA
  • -12V: 62mA

MAIN OUTPUTS

  • Output type: zero-impedance, compensated for electrolytic capacitor distortionFrequency Response: +/-0.2dB max deviation, 10Hz - 20kHzMaximum output level: 22.2V peak-to-peakMaximum gain of channels 1 and 2: 8.0dB (hard-panned), 3.1dB (center-panned)Maximum gain of channels 3 and 4, and INS header: 4.9dB
  • Channel bleed-through (Main Level attenuation) Test conditions: Test signal input into each channel with Level knob at 100%. Frequencies from 20Hz to 20kHz tested. Result given as a ratio of the signal measured on main output jacks with Main Level knob at 0%, to the signal measured with Main Level knob at 100%. Worst-case results for any channel and frequency reported.
  • Left output jack: -102dB
  • Right output jack: -90dB
  • Channel bleed-through (channel attenuation) Test conditions: Test signal input into each channel with Level knob at 0% and Main Level knob at 100%. Frequencies from 20Hz to 20kHz tested.
