Description
The Instruō lìon is a 6x6 matrix mixer with a pin style interface similar
to those found on iconic modular synthesizers of the 1970s. Its
applications range from signal routing and effect insert functionality to
true summing with cascaded attenuation capabilities.
Live patching made easy with the use of the included pin and
insert cables.
Need to patch to a new destination? Simply pin your patch on the fly.
Centralise your I/O network with lìon.

Installation
• Confirm that the Eurorack synthesizer system is powered off.
• Locate 16 HP of space in your Eurorack synthesizer case.
• Connect the 10 pin side of the IDC power cable to the 2x5 pin
header on the back of the module, confirming that the red stripe on
the power cable is connected to -12V.
• Connect the 16 pin side of the IDC power cable to the 2x8 pin
header on your Eurorack power supply, confirming that the red
stripe on the power cable is connected to -12V.
• Mount the Instruō lìon in your Eurorack synthesizer case.
• Power your Eurorack synthesizer system on.
Note:
This module has reverse polarity protection.
Inverted installation of the power cable will not damage the module.
Specifications
• Width: 16 HP
• Depth: 27mm
• +12V: 30mA
• -12V: 30mA

Key
1. Inputs
2. Outputs
3. Patch Points

When referring to matrix mixers, it's a good idea to refer to the different
Patch Points by rows and columns. For instance, talking about [1, alpha]
would refer to the Patch Point on the top row and first column (top left).
[4, gamma] would refer to the Patch Point on the fourth row and
third column.
Inputs: lìon includes six DC coupled inputs for audio and control voltage
signals, labeled 1, 2, 3, 4, 5, and 6.
Outputs: lìon includes six DC coupled outputs for audio and control
voltage signals, labeled alpha, beta, gamma, delta, epsilon, and zeta.
• The alpha and beta Outputs will always output summed signals at
unity gain.
• The gamma, delta, epsilon, and zeta outputs mix at unity gain from
pinned sources, but will also sum the signal from the output directly
to their left (if that output is unpatched). This throughput has a gain
reduction of 1/3. Multiple Pin Cables in the same row will add gain
to the input signal.

Multiple Pin Cables in the same row will add gain to the input
signal. For example, if an input signal is present at Input 1, and a
Pin Cable is inserted to [1, alpha] the signal at the alpha Output
and beta Output will be unity gain. At the gamma Output, the
signal will be attenuated by 1/3. At the delta Output, another
1/3, cascading attenuation as the channel outputs are summed.

• Similarly, if an input signal is present at Input 1 and a Pin Cable
is inserted to [1, zeta] the signal at the zeta Output be unity gain.
Adding another Pin Cable at [1, epsilon] will increase the signal's
gain by 2/3. Adding yet another Pin Cable at [1, delta] will
increase the signal's gain by another 2/3, so on and so forth,
cascading gain as the channel outputs are summed.
Patch Points: The Patch Points are used for signal routing and effect
insert functionality.
• Patching out from the Patch Points with a standard mono patch
cable will serve as a passive multiple from the signal at the input.

Patch Examples
Mixing:
• Connect different signals to any of the Inputs and monitor from the
zeta Output.
• Insert Pin Cables to the Patch Points on any of the
corresponding rows.
• Different levels of attenuation are applied based on which
Patch Points you insert Pin Cables into.
• Adding multiple Pin Cables in a row will add gain to the
input signal.
For instance, with a signal present at Input 1, inserting a Pin Cable to
[1,zeta] will pass the signal to the zeta Output at unity gain. As the Pin
Cable is moved to the left, the signal will attenuate the signal by 1/3
with each consecutive Patch Point with the exception of the first two
Patch Points which apply the same amount of attenuation.

Cross Modulation:
• Insert three audio signals from one oscillator to Inputs 1-3 of lìon.
• Insert another three audio signals from a second oscillatior to
Inputs 4-6 of lìon.
• Monitor from the gamma Output.
• Connect the alpha and beta Outputs to two inputs on the second
oscillator (FM and wavefold amount, for instance).
• Connect the delta, epsilon, and zeta Outputs to three inputs on the
first oscillatior.
• Any Patch Point on the gamma column will pass audio to the output.
• Any other Patch Point will connect the audio signals from the
oscillators to modulation inputs on the opposing oscillators.
