4U Matrix Mixer

The 4U Matrix Mixer is an active 8 input x 4 output Matrix Mixer in the 4U modular format**
Each of the 8 inputs have up to 2X Gain with use of the input attenuators. With the attenuator set to 12 o’clock, the incoming signal will be unity gain, fully clockwise and it will be 2X gain.

Each Summing Node input has a 3-Way toggle switch with the option to turn On, Off and Invert the signal from the corresponding output. There are 1/4” inputs available on input 8 and output A (with attenuator trimmer on the back of of the pcb to set your preferred output level for 1/8” jack) for external processing.

At the moment the Assembled Module panels are built on demand and can take 2-3 weeks pending no other global part shortages.
Desktop versions are enclosed in a 2” aluminum boat powered from a 9-15Vdc wallwart (included with purchase).

Inputs: 8 Active Inputs w/ 2X gain (one optional 1/4” input)
Outputs: 4 buffered outputs (one optional 1/4” output w/ level adjust)
Size: H7” x W9” x D1” (9 columns wide (9U) in 4U Modular / LW Format)
Current Draw: +12V @ 30mA -12V @30mA

** 4U Modular is a term commonly used for the format most commonly know as “Serge Format” or “Loudest Warning Format”.
Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and
mounting hole style. 4U Modular will patch up just fine with other 4U Serge formats such as Random Source, but it will not
mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website
soon to make this a lot more easy to understand.
