Redback® A 4954
5 Pin XLR - Cat5 Extender (Receiver)
OVERVIEW:
The Redback® A 4954 receives audio from compatible Redback® Cat5e/6 transmitters and converts the signal to a balanced
XLR output with PTT connection. The output level is DIP switch selectable, and the output volume is screwdriver adjusted via
the trimpot on the front of the unit.
The unit is powered from 24V DC, which can be connected to the DC socket on the rear of the unit, or it can be supplied
through the Cat5/6 cabling from other compatible Redback® products. A 24V DC plugpack is supplied for connection to
the DC socket.
The Redback® A 4954 can be connected to compatible Redback® products such as the A 4952 and A 4953. These units
carry the balanced output and push-to-talk (PTT) signal to the A 4954 ensuring seamless operation for paging microphones
(PTT connects to pins 4 and 5 of the XLR socket).
