Lectrosonics R172 - Manual (Page 4)

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.
