Redback A 4952 Operating Manual

Redback® A 4952 5 Pin XLR - Cat5 Extender (Transmitter)
OVERVIEW:
This handy interface box allows balanced signals to be transmitted over long distances using economical UTP data cabling,
and provides easy local zone connection for audio sources. This unit carries the push-to-talk (PTT) signal to the connected
equipment ensuring seamless operation for paging microphones (connects to pins 4 and 5 of the XLR socket).
The unit has adjustable input sensitivities to handle either microphone (3mV) or line levels (1V) and has provision for phantom
power (15V DC). Both of these are DIP switch selectable. The output volume is adjusted via the control on the front.
The balanced output from the A 4952 can be received by the Redback® A 4954 Receiver. 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 such as the A 4954 receiver (24V DC Plugpack supplied).
