Q-MIXI, Q-MIX & Q-MIXO – User’s manual © - Revision 2.0 - Page 1
Q-MIX, Q-MIXI & Q-MIXO - User manual
1 Introduction
Once upon a time, needed a small audio mixer for my own case, including 4 inputs with LEVEL & PAN controls and an
adjustable stereo audio level output, all in 6HP maximum!
The challenge of this new module was multiple:
● Strong focus on ergonomics in maximum 6HP.
● Pro audio components for excellent performance.
● LINE IN & OUT connectors on the rear panel, which allows to add future extension modules.
● Large MASTER stereo output potentiometer.
● Stereo PEAK LED with memory.
● Single electronic board and a boxed power connector.
● Quality capacitors on the audio path.
I made it and, following the positive comments from my entourage, I said to myself "what about marketting it"?
I have since added a sub-mixer (Q-MIXI) and a balanced output module (Q-MIXO) with two independent headphone
outputs.
Q-MIX, Q-MIXI and Q-MIXO use quality capacitors in the audio signal path.
No DC signal can pass through the modules.
Depending on your use and needs, The Q-MIXI, Q-MIX and Q-MIXO modules can be used in 7 combinations:
● Individually

3.1 Package Content.
● One Q-MIX or Q-MIXI or Q-MIXO module with Eurorack compliant front panel.
● One plastic bag containing:
o Two M3 screws + M3 nylon washers.
o One 10/16 pins power ribbon cable.
● Warranty & user manual access card.
3.2 Installation.
If you use only one of the modules, place it where you want according to your personal ergonomics.
If you use 2 or 3 of these modules, it is important to place jointly the Q-MIXI on the left, the Q-MIX in the middle and
the Q-MIXO on the right.
This is important for the rear wiring (see the chapter 3.6)
Choose the installation location of your unit carefully:
● Avoid placing it in direct sunlight or close to a source of heat.
● Avoid locations subject to vibrations, excessive dust, heat, cold, moisture or rain.
Procedure:
1. Only connect the module to a Eurorack bus board powered by a specified A-100 power supply.
Q-MIXI, Q-MIX & Q-MIXO – User’s manual © - Revision 2.0 - Page 4
2. Switch OFF and disconnect the Eurorack case from the main power supply by unplugging it from the wall
socket!
3. Make absolutely certain that the ribbon cable has the right orientation by connecting the indicated red stripe
on the negative 12 Volt side of your Eurorack case bus board.
4. Carefully place the module on an appropriately spaced spot on your Eurorack and fasten it firmly in place with
the supplied screws and nylon washers. Replace any covers or blanking plates that you removed to install the
module and screw them in firmly.
5. Reconnect the Eurorack case power cable back into the main power supply and switch the case power on.
6. If it doesn’t seem to be working as expected, immediately disconnect the system from the main power supply
again. In this case, double-check the connections, making completely sure that the ribbon cable is the right
way round where it connects to the module and the bus.

3.6 Back Wiring.
Q-MIXI is equipped on its back side with a cable in a white sheath. You can connect it directly to the LINE IN socket of
the Q-MIX.
Q-MIXO is equipped on its back side with a cable in a black sheath. You can connect it directly to the LINE OUT socket
of the Q-MIX.
If you use Q-MIXI and/or Q-MIXO without the Q-MIX, please leave the cables unconnected.
NB: It is not possible to connect the Q-MIXI directly to the Q-MIXO
4 Use.
Well, is it necessary to explain how to use the LEVEL, PAN and Master Out adjustements of these modules?
There is abundant literature on the subject, and if you really have a question, do not hesitate to contact me personally
at [email protected]
I would be pleased to answer you because you made the effort to read this user manual up to here.
