Mixology

Description
Mixology takes the mixing and routing of modular audio signals to a new level of
sophistication. It is a stereo, four channel mixer with a performance oriented interface.
Each channel has a high quality VCA circuit which allows for amplitude modulation,
audio ducking, and voltage controlled panning. In addition, CV over send amount and
a stereo return channel make interfacing with effects a breeze. Whether on stage or in
the studio, Mixology is the perfect centerpiece for controlling and performing audio
signals.
-Stereo four channel mixer
-High quality VCA per channel
-Ergonomic performance layout with level faders
-Pop-free mute and solo functionality
-Voltage controlled panning that supports audio rate modulation
-Constant power panning
-CV over send amount
-Stereo return channel
-+3dB of gain per channel
-Analog VU meter
-Bipolar CV inputs allow for audio ducking, dynamic panning, and effect throws

Installation
To install, locate 28 HP of space in your Eurorack case and confirm the positive 12
volts and negative 12 volts sides of the power distribution lines. Plug the connector
into the power distribution board of your case, keeping in mind that the red band
corresponds to negative 12 volts. In most systems, the negative 12 volt supply line is
at the bottom.
The power cable should be connected to the Mixology with the red band facing the
bottom of the module.
Specifications

General Functions Overview
1. Input:
Modular level signal input
2. Level CV Input:
Control voltage input for Level
Control voltage is added to the fader position
Range: ±8V
3. Send CV Input:
Control voltage input for Send
Control voltage is added to the knob position
Range: 0V –5V
4. Pan CV Input:
Control voltage input for Pan
Control voltage is added to the knob position
Range: ±5V
5. Send:
Post fader effects send that sets the amount of signal routed to the Send Output
If the knob is far left, no signal for the corresponding channel will be routed to the
Send Output
If the knob is far right, the signal routed to the Send Output will be at unity gain for the
corresponding channel
6. Pan LEDs:
LED indication of the pan position across the stereo field

7
7. Pan:
Sets the pan position across the stereo field
If the knob is far left, the left LED will be fully illuminated and signal will only emit from
the Left Output
If the knob is far right, the right LED will be fully illuminated and signal will only emit
from the Right Output
Constant power panning implementation ensures that the perceived loudness of the
output signal is constant, regardless of the pan position across the stereo field
8. Level Fader:
Sets the level of signal that is sent to the Left and Right Outputs
If the fader is all the way down, the incoming signal will be fully attenuated and not
present at the Left and Right Outputs
If the fader is set to the unity marking, the incoming signal will be full scale (not
attenuated, nor amplified)
If the fader is all the way up, the incoming signal will be amplified by +3 dB
9. Solo:
Button that, when pressed, will mute all non-corresponding channels and only output
the corresponding channel from the Left and Right Outputs
If the button is illuminated, solo is active for the corresponding channel
If the button is unilluminated, solo is inactive for the corresponding channel
Only one channel can be soloed at a time
It is important to note that a muted channel can still be soloed

8
10. Mute:
Button that, when pressed, will stop the corresponding channel from passing to the
Left, Right, and Send Outputs
If the button is illuminated, the channel is muted
If the button is unilluminated, the channel is unmuted
Any number of channels can be muted at a time
11. Left Output:
Modular level signal output for the left channel of the final mix
12. Right Output:
Modular level signal output for the right channel of the final mix
13. L/Mono Return Input:
Left/Mono effects return input
If no signal is present at the Right Return Input, the signal present at the L/Mono
Return Input will be normalled to the Right Return Input
It is important to note that this input can be used as an additional mono input
14. Right Return Input:
Right effects return input
It is important to note that, along with the L/Mono Return Input, both inputs can be
used as an additional stereo input
15. Send Output:
Mono effects send output
Adjusting the Send control will set the amount of signal routed to the Send Output
16. VU Meter:
Amplitude indication of the Left and Right Outputs

9
17. Master Fader:
Sets the level of the final mix
If the fader is all the way down, the final mix will be fully attenuated and will not pass to
the Left and Right Outputs
If the fader is all the way up, the final mix will be full scale (not attenuated, nor
amplified)
