ANTENNA INPUTS
hese inputs connect to any 50 ohm antenna with a BNC type connector.
12 VDC INPUT
This input connects to the supplied CH-12 AC adapter for powering the receiver from a 110/120V AC source. The
receiver may also be powered from external 12 volt DC sources using the correct plug (Switchcraft S-760 power
plug). The center pin is positive. (+).
AUDIO OUTPUTS
XLR: This XLR type connector supplies a balanced, low impedance output at microphone level. The audio signal
is present on pins 2 and 3, while pin 1 is ground. The output level of this jack is controlled by the OUTPUT
ATTENUATOR control on the front panel of the receiver. Pin 2 is “hot” in terms of polarity.
1/4": A high level (700mV max.) output at medium impedance (600 ohms). This is a three conductor jack with
the tip and ring carrying the signal and the sleeve as shield. The tip is “hot” in terms of polarity. Output from this
jack is controlled by the OUTPUT ATTENUATOR control on the front panel.
RCA: A 1 Volt “line” output at 1K Ohms. The output of this jack is not controlled by the OUTPUT ATTENUATOR
control on the front panel.
AUDIO IN: This is an audio input providing a unity gain mixing bus input via a standard RCA jack. Signal applied
to this jack will appear at all three output jacks. This input is provided as a convenience in multiple channel
installations with simple mixing requirements, or for patching in another audio source (tape deck, etc.). Multiple
DR185 receivers may be “stacked” with mixed audio output by connecting the LINE OUT jack of one receiver to
the AUDIO IN of the next receiver, and so on. Up to four or five receivers may be “stacked” in this manner before
noise build-up becomes objectionable.
