OPERATION
Notes:
• You can use a wireless and wired
microphone at the same time.
• Be sure to select the correct fre-
quency channel for your PA sys-
tem to match your wireless
microphone’s operating fre-
quency channel.
Using a Wireless Microphone
1. Rotate WIRELESS MIC VOLUME
counterclockwise to the mini-
mum level (the smallest dot on
the left side of the knob).
2. Select the frequency channel on
the PA system to match your
microphone’s operating fre-
quency channel or channel com-
bination by setting the
DIP switch
located on the back of the PA
system.
For example, if your microphone
frequency is A, use a sturdy
pointed-object (like a ball-point
pen or finger nail file) to set each
switch on the
DIP to as indi-
cated by the operation channel
combination table located on the
back panel. The “ ” represents
the raised nub on each switch.
Notes:
• Wireless microphones are sold
in three channel combinations:
AEH, BDG, and CFH.
• If you use two receivers in the
same room with a separate
wireless microphone assigned
to each receiver, make sure
the channels are not adjacent
(follow in alphabetical
sequence). For example, if one
receiver is set to channel G
and the other to H, it will create
interference. To remove the
interference, set one receiver
to H and the other to F.
3. Set ON/OFF to ON . POWER
lights.
4. Set the wireless microphone’s
ON/OFF switch to ON. READY
