Setting Up the Transmitter
Your Peavey Assisted Listening System requires minimum installation. Simply place the
transmitter on any flat surface, connect your mixing board to the transmitters back panel input
(See connecting Audio input below), connect the included power supply (as explained below),
and the transmitter is ready to broadcast to any number of Peavey Assisted Listening System
receivers operating on the same frequency.
Powering the Transmitter
Connect the AC adapter provided into the 9V DC JACK (1) on the back panel of the transmitter.
Plug the other end into an AC wall outlet. Press POWER SWITCH (2) the POWER ON LED (3)
will illuminate.
Antenna
Extend ANTENNA (4) fully and position 90 degrees from top of the transmitter.
Connecting Audio Input
The LINE IN JACK (5) on the rear panel lets you connect the Peavey Assisted Listening System
to your mixing console. This ¼” mono phone jack accepts an unbalanced line level audio source
at 0 dBm nominal signal level. If your mixer has XLR outputs only, you will need an XLR-to-
phone plug adapter, available from most music equipment stores or sound contractors.
Using a Microphone
The MIC JACK (7) on the front panel allows wireless cueing of on stage performers.
IMPORTANT: This ¼” mono phone jack is designed for an electret condenser microphone, and
9V DC power is present at the input jack. If you wish to use a conventional dynamic microphone,
at least 20 dB more gain is required, and a preamp should be used. If a preamp is used, be sure
to have a blocking capacitor (1mdf) between the preamp output and the mic input. If a dynamic
mic is plugged into the mic input by mistake, there should be no damage because the current is
limited to 1.0 mA.
Audio Input Gain Adjustment
You can quickly adjust the transmitter to obtain optimum performance with the INPUT GAIN
CONTROL (8). The audio modulation indictor LED, marked SIG (6) will increase in brightness as
the control is turned clockwise, and decrease in brightness as the control is turned
counterclockwise. When the “SIG” LED is flas hing during transmission, the transmitter is
broadcasting properly. (If the LED stays off continuously or barely flashed at all, the input gain
needs to be increased. If the LED stays on continuously and does not flash during modulation,
the input is overloading and needs to be decreased.) You will also need to test the transmitter
