Listen IO
4ms Company
User Manual 1.0 – Jan 2, 2019
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.
The Listen IO 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 or DIY adaptor module (1/4”, banana, etc.) Listen Up
• Two headphone outputs and stereo inputs for use as a compact headphones module

Setting up your Listen IO
1. Power off your Eurorack system.
2. Connect the free end of the included power cable to a 16-pin Eurorack
power header on your power supply distribution system. The red stripe
should match the white line or -12V marking on the power distribution
board. The other end of the power cable is a 10-pin connector which
should already be connected to the with the red stripe on the Listen IO
power cable orientated towards the bottom of the module. Note: The
Listen IO is reverse-polarity protected, but incorrectly connecting any
module can damage any other module on the power bus.
3. Using the included screws, securely attach the to the rails of Listen IO
your case.
4. Power on your Eurorack system.
Line to Modular Section
The top half of the Listen IO converts low level signals such as line, instrument, or
microphone to modular level. There are two independent channels which share a common
Gain knob.
Line In jacks
The two Line In jacks accept a wide range of signals; any guitar, effect pedal, synthesizer,
keyboard, musical toy, etc. can safely be plugged into these jacks. Most microphones will
also work, with the exception of mics that require power to be delivered over the cable
(Phantom-powered and electret mics). These jacks are mono. If you have a stereo signal,
patch the left channel into the left jack and the right channel into the right jack.
Gain knob
The Gain knob controls how much the signal is boosted. Although the signal paths of Line In
the left and right channels are separate, this knob controls both channels. The gain can range
from negative infinity (muted) to about +30dB (which is about a voltage gain of 30).
LED bar graph
The LED bar graph displays the level of the signal after the gain is applied. It also shows if
there is any clipping. The more lights that are on and the brighter they are, the louder the
signal. If the top light flashes red, then the signal is clipping. Adjust the knob down until Gain
the red light stays off to avoid clipping. It’s perfectly safe to clip and even overdrive the signal
for a distortion effect if you wish.
Mod Out jacks
The two Mod Out jacks output the boosted signal. The left jack is the output for the boosted
signal of the left jack, and the right jack is the output for the boosted signal of the Line In
right jack. These jacks are mono. Typically, you would patch these to a Eurorack Line In
module.

INS header
The INS header of the top section can be used to connect to an adaptor module such as the
Listen Up. This allows you to use a different size jack, such as 1/4” (6.35mm). The INS
header has pins for the left channel (bottom pin), right channel (top pin), and ground (center
pin). The input impedance is 100k. Whatever signal is present on the header will be added to
the signal on the jacks: both can be used simultaneously. Line In
Modular to Line Section
The bottom half of the converts Eurorack signals to line or headphone level. The Listen IO
outputs are compatible, instrument-level equipment. There are two independent channels
which share a common knob. Level
Mod In jacks
The two Mod In jacks are the inputs to the bottom half of the module. Typically, you’ll patch a
modular signal into these jacks. These jacks are mono; if you have a stereo signal, patch the
left channel into the left jack and the right channel into the right jack.
Level knob
The Level knob controls how much the signal is attenuated (The process of taking a Mod In
louder signal and converting it to a lower level signal is called ). Although the attenuation
signal paths of the left and right channels are separate, this knob controls both channels. The
amount of attenuation can range from negative infinity (muted) to 0dB, which means the
signal level is not changed.
LED bar graph
The LED bar graph displays the level of the attenuated signal. The more lights that are on
and the brighter they are, the louder the signal. Unlike the top half of the module, the bottom
half will never cause clipping, and therefore there are no red lights.
Line/Headphones Out jacks
The two Line Out jacks output the attenuated signal. These are multi-purpose jacks and can
be used as mono line level outputs or stereo headphone outputs.
If you’re using these jacks with mono cables, then use the left jack as the output for the
attenuated signal of the left jack, and the right jack as the output for the attenuated Mod In
signal of the right jack. Mod In
If you’re using these jacks with headphones, then both jacks will output both signals. The left
jack will output the left signal in the left ear and the right signal in the right ear. The right jack
swaps the left and right signals and outputs the left signal in the right ear and the right signal
in the left ear.
OUTS header
The OUTS header of the bottom section outputs the same signal as the jacks, Line Out
without the ability to drive headphones. This header can be used to connect to an adaptor
module such as the for outputting with different size jack, such as 1/4” (6.35mm). Listen Up
The OUTS header has pins for the left channel (bottom pin), right channel (top pin), and
ground (center pin). The output impedance is 1k, and the header can be used
simultaneously with the jacks. Line Out
