RECEIVER REAR PANEL

12 VDC 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 to 18VDC sources using the correct plug (Switchcraft S-760 power plug). A diode

bridge is used in the external power input, so that the UCR190 will operate properly from either polarity.

AUDIO OUTPUT

Supplies a balanced, low impedance output at microphone level. The audio signal is output on pins 2 and 3, while pin

1 is ground. The output level of this jack is controlled by the OUTPUT control on the front panel of the receiver. The

connector is a standard XLR type.

BATTERY REPLACEMENT

The UCR190 is powered by a standard alkaline 9 volt battery. It is important that you use ONLY an ALKALINE

battery for longest life. Standard zinc-carbon batteries marked “heavy duty” or “long-lasting” are not adequate. They

will provide only about one hour of operation. Similarly, nicad rechargeable batteries give less than 2 hours of

operation, and will also run down quite abruptly. Alkaline batteries provide about 5 hours of operation.

To open the battery compartment, press outward on the cover door in the direction of the arrow as shown in the

drawing. Only slight, sliding pressure is needed to open and close the battery door.

TO OPEN

AUDIO OUTPUT 12 VOLT DC INPUT

Swing the door open and take note of the polarity marked inside showing the location of the positive (+) and negative

(-) terminals. Insert the battery and close the cover by pressing in and across, reversing the opening procedure

outlined above. Note that the battery door will NOT close if the battery is inserted incorrectly, since the terminals will

hit a protective polarity barrier. Do not force the battery in.
