What's In The Box - Redback A 4432 Operating Manual

Redback® A 4432 4+4 Channel Mixer
1.0 INTRODUCTION
This mixer has been developed as a request from leading audio installation companies.
It combines 4 channels of the ever reliable front end Redback Mixers along with four switch selectable RCA inputs. Inputs
1 - 4 are able to be configured for either mic or line use. Mic inputs are 5 pin pluggable euro blocks allowing either PTT or
VOX muting. Euro blocks allow for easy field installation. Line inputs are 2 x RCA. Dip switches are provided for each input
enabling phantom power on/off, line level sensitivity setting from 100mV - 1V, and priority on/off.
Input 5 consists of 4 sets of 2 x RCA sockets which are selected by the front panel switches. This allows for several differ-
ent music sources to be connected and selected as desired. A front mounted 3.5mm audio jack for portable devices will
override the fourth input set of RCA's when connected.
The cascading priority structure has input 1 overriding all inputs. Inputs 1 - 4 automatically mutes input 5.
Alert and Evac tones along with pre-announcement chimes are in built and assumes priority between inputs 1 and 2.
These user changeable tones are MP3 based and stored on the internal Micro SD card.
Each input is supplied with volume control along with individual recessed treble and bass controls. Inputs 1 - 4 have adjust-
able VOX sensitivity controls.
A 24V DC output (limited to 120mA current draw) becomes live when any triggers are activated or VOX/PTT circuitry
becomes active.
Provision is included to connect a remote wallplate A 4433 via Cat5 cable to enable remote selection of any of the 4
sources connected to input 5 along with remote volume adjustment.
Further to this, connecting either the A 4931 remote input plate or A 4932 remote input box to the A 4433 allows
connection of a music source or microphone from a remote location. When active this will automatically mute any music
source connected to input 5.
The unit operates from 24V DC and has provision for battery back up.
