This unique Redback PA mixer features six input channels which are user selectable for either balanced mic or line as well as two dedicated line level RCA inputs and a 3.5mm audio jack for portable devices. The unit has six levels of VOX priority on inputs 1- 6 with adjustable VOX sensitivities on each input, and a 24V DC output (limited to 120mA current draw) which becomes live when any triggers are activated or VOX/PTT circuitry becomes active. This model includes a set of Mute contacts which can be connected to the buildings Fire Indicator Board (FIB). When the FIB operates it triggers these contacts, rendering the local PA/BGM system inoperative so the main emergency evacuation system has precedence.
The mixer incorporates an MP3 based message player for playback of Alert/Lockdown, Evacuation/Fire or Chime tones.
The emergency tones once activated, will mute inputs 2 - 8, regardless of their priority settings. Input 1 will override the emergency tones so that it can then be used for emergency paging. With the addition of an A 4660A paging console, paging and activation of the emergency tones can be achieved via the console. Input 1 will still override the emergency tones, but emergency paging from the A 4660A will override input 1.
