Audio Mixer

from $25.00 
DESCRIPTION

The Audio Mixer is a compact, manual three-input, one-output module designed for audio applications. It features two inputs with unipolar level controls and a third input with a unipolar attenuator and phase switch, allowing for phase inversion.

DETAILS

  • 3 AC coupled inputs

  • 3 unipolar attenuated inputs (one with invert/mute switch)

  • Current: TBD

  • PCB Size: 6” x 1”

Audio Mixer Overview

The Audio Mixer is a compact, manual three-input, one-output module designed for audio applications. It features two inputs with unipolar level controls and a third input with a unipolar attenuator and phase switch, allowing for phase inversion.

This mixer can be paired with other mixers, VCAs, and output modules to support a wide range of signal routing and mixing configurations. A two-inch version is also available for high-density systems.

Note: This mixer is AC-coupled, making it suitable for audio signals only.

Mechanical Parts BOM generally required for building Low-Gain Electronics Modules

Serge Modular Ecosystem Compatibility
Modern Serge-style 4U systems use two primary mounting standards: Loudest Warning–style and Random*Source–style.
Low-gain Electronics modules follow the Loudest Warning–style mounting format (unless stated otherwise) and are electrically
compatible with all Serge-style systems, though mounting (panels) and power adapters may be required for some installations.
