RECEIVER REAR PANEL

ANTENNA

terminals -- Standard BNC 50 ohm connectors for connecting the antennas. The R172 is normally

shipped with a telescoping whip antenna and a coaxial antenna. Rack mounted units are shipped with two coaxial

antennas.

ANTENNA MODE -

The unit may be operated as either a single antenna or a dual antenna system. If two

antennas are used set the switch to

DUAL

. If operating with only one antenna, set the switch to

SNGL.

12 VDC DC POWER

-- Connect the power supply here -- the CH-12 AC adapter is supplied with the receiver for

powering the unit from a 110 V AC outlet -- the receiver may also be powered from 12 volt DC sources using the

correct plug (Switchcraft S-760 power plug); the center pin is positive (+).

AUDIO OUTPUTS

MIC LEVEL

-- 3 pin XLR at microphone level (80mV max.); 200 ohm impedance for either balanced or unbalanced

inputs

LINE LEVEL

-- RCA phono jack at "line" level (1 volt max); 1K ohm impedance for unbalanced inputs. The output

level of this RCA jack is not affected by the front panel

OUTPUT LEVEL

control.

SEPARATE MIXED SWITCH -

Allows the "A" and "B" audio signals to be mixed, if desired. Setting the switch to

SEPARATE

will keep the signals from the two channels discrete. Setting the switch to

MIXED

will mix the signals

internally, allowing both channels to be output through either output jack.

AUDIO INPUT

(mixing bus)

AUX INPUTS

-- RCA phono jack inputs accept external tape deck or other audio source; mixes audio with receiver

output. Also allows "stacking" multiple receivers.
