4x4 Active Matrix Mixer – 4U Modular Format

The 4x4 Active Matrix is a 4-input by 4-output active matrix mixer designed for the 4U modular / Loudest Warning (LW) format.

  • Inputs:

    • Channels 1 & 2 feature both 1/8” and banana jack inputs, each with a toggle switch for selecting between x1 and x2 gain.

    • Channels 3 & 4 include 1/8”, 1/4”, and banana jack inputs, along with toggle switches for x1 or x10 gain—ideal for interfacing line-level or guitar pedal signals with your modular system.

    • Each input has a dedicated input attenuator before it reaches the matrix mix section.

  • Mixing Matrix:

    • Each of the four outputs has its own summing node with a 3-way toggle switch per input, allowing you to route that input as On, Off, or Inverted to the output.

    • Outputs A, B, C, and D are gray banana jacks, while Output A features both a banana jack and a 1/4” output with its own output level attenuator.

  • Build & Availability:

    • Assembled modules are built to order and typically ship within 1–2 weeks, depending on part availability.

Specifications:

  • Inputs: 4 active inputs

    • Channels 1 & 2: Banana or 1/8” inputs with x1/x2 gain

    • Channels 3 & 4: Banana, 1/8”, and 1/4” inputs with x1/x10 gain

  • Outputs: 4 buffered outputs

    • Output A includes both banana and 1/4” with level control

  • Dimensions: 7" (H) x 5" (W) x 1" (D) — fits 5 columns wide in 4U LW format
    Current Draw: +12V @ TBDmA -12V @TBDmA

** 4U Modular is a term used for the format most referred to as “Serge Format” but broken up into individual modules, alternatively referred to as “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 STS, Random Source, but it will not mount in STS, RS or Buchla Boats (or power off Buchla power for that matter).
