Listen IO

$125.00

The Listen IO is a simple module which gets signals in and out of a Eurorack system by converting to and from normal modular levels. The top section converts any external signal to modular levels by providing up to 30x gain (+30dB), allowing you to use table-top synthesizers, keyboards, phones/tablets, computers, toys, microphones, etc. in your patches. The bottom section does the opposite: modular signals are converted to normal line level signals. The bottom two jacks can be used as line outs or as headphone jacks, so you and a friend can listen in stereo at the same time. 
Each section has two inputs and outputs for use with a stereo signal or two mono signals. An LED bar graph for each output shows the signal level and clipping.

 Basic Features:

  • Line to modular conversion, and modular to line/headphone conversion
  • Works with guitars, table-top synths, effect pedals, keyboards, groove boxes, and many microphones 
  • Dual mono or stereo conversion
  • LEDs show signal level and clipping
  • Gain knob allows for wide range of boost or cut
  • Headers in back for connecting to Listen Up or DIY adaptor module (1/4”, banana, etc.)
  • Two headphone outputs and stereo inputs for use as a compact headphones module

Electrical and Mechanical Specifications:

  • Module size:
    • 6 HP Eurorack format module
    • 0.95" (24mm) maximum depth with power cable
  • Power consumption:
    • Maximum values: All output jacks shorted to ground, 22Vpp signal on all input jacks, knobs at 100%
    • +12V: 62mA
    • -12V: 55mA
  • Line to Mod section (top):
    • Output: 1k impedance
    • Input: 100k impedance

    • Channel cross-talk:
      • Test conditions: Test signal input into left Mod In jack. Sine wave at frequencies from 20Hz to 20kHz tested. Result given as a ratio of the appearance of test frequency measured on right Line Out jack to left Line Out jack. Test repeated with left and right jacks swapped. Worst-case results for any channel and frequency reported.
      • 20Hz – 20kHz: <-110dB

Included with the Listen IO:

  • 10-to-16 pin power cable
  • 2 M3 Knurlie screws

Connect your Listen IO to other Listen modules or the WAV Recorder using the Audio jumper cable
