REAR PANEL CONTROLS AND FUNCTIONS

DC IN JACK

The UCR205D can be powered from external 10 to 16.5 Volts

DC applied directly to this jack, or conventional 110 VAC

sources via the supplied CH20 adapter. The UCR205D is pro-

tected from reverse polarity conditions which prevents damage

if a positive ground power source is applied. The center pin of

this jack is POSITIVE. This power connector is threaded to

allow the plug to be locked to prevent accidental pull-out.

AUDIO OUTPUT XLR JACK

This jack is a standard 3 pin XLR connector. For balanced

applications, Audio High is on pin 2, audio Low is on pin 3, and

audio Common is pin 1. For unbalanced use, the signal is

developed between pin 2 (Audio High) and pin 1 (Audio Com-

mon or Ground.) It’s not necessary or desirable to ground pin 3.

(The output is balanced and center tapped.)

MONITOR

This is an audio output to drive a wide variety of different types

of headphones. It is also usable as a second high quality audio

output to drive recorders or external audio devices. The level at

this jack is independantly adjustable with the associated knob.

RANGE SWITCH

The audio output range switch is located on the rear panel and

is the switch nearest the front panel. This switch controls the

range of adjustment of the front panel Audio Output control. In

the Low position the adjustment range is from –50dBm to –

20dBm, the High position allows an adjustment from –30dBm

to 0dBm, and the Fixed position sets the audio output to a fixed

+8dBm with no front panel control.
