Auxiliary Audio Connection

The 6 pin telephone jack (RJ-11) may be used to supply audio into and out of the base station. RTS Matrix type intercoms may be interfaced to the base station through this jack.

Since audio is not “Channelized” through this jack, the audio channel switch has no effect on the audio passed through the jack. The audio will be heard on both channels 1 and 2 equally, audio generated by the BTR on channels 1 or 2 will be sent to the Aux- iliary Jack.

Dummy Load

In the case where a wired intercom will not be used with the base station or only one of the audio chan- nels are connected to the unit, it is important that the dummy load(s) (supplied) be installed.

I/C Switch = Set for Telex

Telex dummy loads should be plugged into both XLR ports if a wired Telex intercom system is not being used. A single Telex dummy load should be plugged into the unused channel’s XLR port if only one channel is connected to an intercom system.

I/C Switch = Set for RTS

RTS dummy load should be plugged into one of the XLR ports if an RTS intercom system is not being used.

NOTE: If the dummy load is not placed properly, an annoying squeal may result that may cause dam- age to the ears.

Power Connection

Insure the Power ON/OFF Switch on the front of the base station is in the “OFF” position. Connect the supplied AC power supply cord to the receiver at the socket labeled “POWER”. Connect the power supply unit to an AC outlet supplying 105 to 125 VAC, 60 Hz.
