CR187

Receiver Rear Panel

Main Output XLR Jack 12 VDC Input

Audio Output XLR Jack

The Audio Output XLR Jack 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.

12 VDC Input

The 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

other external 12 VDC sources using the correct plug

(Switchcraft S-760 power plug). Although the CR187 is

a negative ground device, a diode bridge is used in the

external power input, so that the CR187 will operate

properly from either polarity.

Warning: Because the CR187 is a negative

ground device, do not connect this receiver

to a positive ground device through the audio

cabling. Damage to either device could result.

Battery Replacement

The CR187 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 abrupt-

ly. 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. 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.
