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.
