Thank you for choosing ST·MAR
for your Eurorack System.
Powering up
Turn off the power of your modular synthesizer.
Double check the power cord polarity. If you plug the module backwards, you might
damage its electronic circuits.
If you flip over your ST·MAR over, you will find the “RED” mark at the PCB power
connector, which must match the colored line on the ribbon cable.
Once you have checked all the connections, you can turn on your modular system.
If you notice any anomalies, turn your system off right away and check again your
connections.

ST·MAR is a 3-channel Stereo Mixer module in 8HP, designed to efficiently
combine various audio and CV sources.
It features Volume adjust controlled by CV, a MUTE switch for audio silencing, and
a VU meter to monitor signal levels accurately. Additionally, it includes a Master
volume control, all within a compact module, making it an essential tool for blending
stereo signals.
Stereo mixers are particularly valuable when working with Eurorack setups that
feature stereo sound sources, like effects processors or stereo filters.

Stereo Inputs
Audio is normalled
from L to R.
Control Voltage
Use xternal signals to
modulate the volume.
5V = max gain
Mute Selector
Stereo Outputs
Level Indicators
Shows the strength of the
output signals (L and R) and
whether clipping occurs. Master Control
Adjust the overall volume of
the sum of the 3 channels.

Channels 1, 2 & 3
• VOLUME Control
Each channel comes with an individual
volume control. It acts as a gain adjust
when the CV is not connected.
However, when the CV is connected, it
acts an attenuator of the incoming signal.
• MUTE Switch
It allows you to temporarily disable the
audio output of the corresponding
channel. You can quickly mute a track or
instrument to focus on other elements of
the mix.
If it is pointing down, the mute function is
activated.
• Stereo Inputs · L / R
You can connect any kind of signal:
audio, DC voltages, envelopes, LFOs…
Audio is normalled from L to R.
• Control Voltage
Adjust the Volume externally using the
CV input.
Envelopes, LFOs, random voltages…
throw whatever you want into it.
0V = -inf gain
5V = max gain (0dB)

• Master Volume
Adjust the overall volume of the sum of the
3 channels.
• Stereo Outputs · L / R
Modular level signal outputs, impedance of
10k Ohms.
• LED Indicators
Watch in real time how the output voltages are
behaving before the master volume control in
the built-in LEDs
CLIP shows whether clipping occurs.
SIGNAL shows the strength of the output
signals (L and R).
