RECEIVER UNIT
Operation
Switch on the wireless microphone receiver unit by pressing the POWER switch and the POWER
light will illuminate to show the receiver unit is working. Raise the aerial to the maximum height. The
positioning of the aerial is not critical for performance, ideally it should be fully extended. Switch ON the
microphone, checking that the red LED comes on for a second and then goes off. When the microphone
is ON, the SIGNAL light will illuminate on the receiver unit.
The wireles microphone is now ready for use, adjust the volume and tone levels of your amplifier system
as well as the receiver and the bodypack as required. When the wireless microphone is not being used
turn OFF the microphone.
Note that switching the microphone on and off can cause interference that will be heard if the mic
volume level of the amplifier system still set high.
SYSTEM INSTALLATION
To connect the wireless microphone to your amplifier system refer to the installation diagram above.
Using the supplied screened jack-to jack lead, connect from the AF OUT jack socket to the
MICROPHONE INPUT socket on your amplifier. Plug the mains power adaptor into a suitable mains
socket and plug the lead connector into the DC 12V input socket.
