Redback® A 4435A Mixer 4 Input & Message Player
Overview
1.0 OVERVIEW
1.1 INTRODUCTION
This unique Redback PA mixer features four input channels which are user selectable for either balanced mic, line or aux-
iliary use. In addition it incorporates a four channel SD card based message player making it an excellent choice for retail,
supermarkets, hardware stores and more.
The mixer could be used for general paging and BGM applications, and the message player for customer service applica-
tions, in-store advertising or for pre-recorded commentary at galleries, display stands etc.
The message player and each input all have individual level, treble and bass controls. Vox muting/Priority is provided for
channels one and two with front panel adjustable sensitivity. The message player priority slots in between inputs one and
two. Custom messages, tones and music may be loaded onto the message player SD card. The messages are activated by
a closing set of contacts. If input one is active when a message contact is closed, the message is queued and played once
input one is no longer in use.
Messages are played on a first in, best dressed (FIBD) basis, and will also be queued if one message is playing and another
is activated.
Inputs 1 and 2 have priority and would be used for telephone paging or interfacing with an Evacuation system.
BGM should be fed to inputs 3 or 4 and not to inputs 1 or 2, as any message will not play whilst audio is playing on inputs
1 or 2 until there is a break. I.e. if it is music, the message may not play for several minutes. If the mic is being used, this
is the same case, but a PA announcement generally only goes for a few seconds, in which case a message will play shortly
after.
Input four is also fitted with a 3.5mm jack input for connection to a smartphone/tablet as an audio source. When con-
nected, this overrides any source connected to input 4 on the rear panel. Each input has a 3 pin XLR (3mV) and dual RCA
sockets with adjustable sensitivity settings. These can be set 100mV or 1V for the stereo RCAs. Message player contacts
are provided via pluggable screw terminals. 24V DC operation from the included power supply or battery backup.
