 Overview

The Redback® mixer delivers a flexible and installer-friendly solution with one microphone/line input and three additional line inputs (all internally mixed to mono), plus a front-panel 3.5mm music input and integrated Bluetooth® receiver, both of which automatically override Input 4. Inputs can be routed to Output 1, Output 2, or both, with outputs provided on balanced XLR and RCA at 1V. Each input includes independent level, bass, and treble controls, with switchable RCA sensitivity (100mV/1V) and selectable +12V DC phantom power on the mic input.

Additional features include VOX muting from the mic input, 24V DC operation with battery backup terminals, and a compact 1RU 19" rack-mount chassis.
