phone plug to connect the receiver’s AF Out jack to the mixer/amplifier’s aux-
level input. 

 
Power Connection 

Connect the DC plug on the included AC power adapter to the DC power input 
on the back of the receiver. Secure the cord over the cord hook on the back of 
the receiver, to keep the plug from being detached by an accidental tug on the 
cord. Then plug the adapter into a standard 120 Volt 60 Hz AC power outlet.  
 
(Note that the receiver has no power Off/On switch. The receiver will be 
energized whenever the power adapter is connected and plugged into the AC 
outlet. Unplug the power supply from the AC outlet when the system is not in use 
– both for safety, and to conserve energy.) 
 

Antennas 

A novel “dipole” antenna system on the receiver improves operation by providing 
a “ground” element in addition to the usual “signal” element. Position the two 
antennas at 90° in the form of a “V,” or position the left (“signal”) antenna 
vertically and the right (“ground”) antenna horizontally, in the shape of an “L” (Fig. 
B). Use the position that performs better in your operating environment. Be 
certain to extend both antennas to their full 15" (38 cm) length by holding them at 
their bases and pulling out on their caps. Both antenna elements may be 
swiveled to the left and right, but do not attempt to rotate them in a 
screwing/unscrewing motion. To do so may damage the antenna and/or receiver. 
For best performance, locate the receiver so its antennas are in direct line-of-
sight to the transmitter’s likely operating position. 

 

Receiver Controls and Functions 

 

Front Panel Controls and Functions (Fig. C) 

1. ANTENNAS: Position the “signal” antenna (1a) and “ground” antenna (1b) as 
shown in Figure B. 
 
2. POWER INDICATOR: Lights when power is supplied to the receiver. 
 
3. RF INDICATOR: Lights to show presence of transmitter signal. 
 
4. AF PEAK INDICATOR: Only lights when audio distortion is present at 
maximum modulation. Not affected by position of Volume control. 
 

Rear Panel Controls and Functions (Fig. D) 

5. VOLUME CONTROL: Adjusts the audio level at the 1/4" output jack. Does not 
affect AF Peak indicator. 
 
6. DC POWER INPUT: Connect the provided docking power adapter, or other 
12V DC source. (Receiver requires 200 mA.)
