Audio Connections - Redback A 4565B Operating Manual

Redback® A 4565B Evacuation Controller

2.3 AUDIO CONNECTIONS

Provision has been made for two different audio sources to be connected to the unit. These are the BGM input and the
Aux input. Both of these inputs have the same priority and are automatically muted when any other function is activated
i.e. Paging, Alert, Evac or Chime triggering.
BGM Input:
This input is for connecting a background music source to the controller. The stereo sockets are combined internally to
form a mono signal. The volume level is set via the BGM level control on the rear of the unit (See Fig 2.3) so that the vol-
ume cannot easily be tampered with.
Aux Input:
This input is for connecting an auxiliary source to the controller for the purposes of background music where the source
volume is required to be accessible from the front panel. The stereo sockets are combined internally to form a mono
signal.
Audio Output:
This output consists of stereo RCA sockets with an output of 0dBm into a 600Ω input. This is suitable for most PA
amplifier auxiliary inputs.

Rear Panel Volume Controls:
The output levels of the Alert, Evac and bell/chime tones can all be adjusted via trimpots located on the rear of the unit.
Volumes are set as follows:
Evac Vol: This sets the output level of the alert & evac tones.
Chime: This sets the output level of the chime.
NOTE: The microphone volume is affected by the tones level. Set this level after setting the tones volume control as the
mic volume is relative to the tones volume. Adjusting the tones volume up will increase the mic volume, and adjusting the
tones volume down will decrease the mic volume.
