Operating Precautions
Before operating the amplifier, be sure you fully understand all instructions and fea-
tures of the amplifier. do noT turn amplifier on until all input and output connections
have been made. NEVER replace fuses unless power is off.
microphone input connection
The microphone input accepts 1⁄4" phone jack. do not position microphone next to or
facing speakers. This may cause acoustic feedback.
Wireless Operation
Turn on the power on both the wireless receiver and wireless mic-1 making sure both
are set to matching chanels, either “A” or “B”.
auxiliary input
one auxiliary input is provided for radio tuner, tape recorder, cd player or multimedia
equipment. output level is adjusted by the auxiliary volume control.
tone / equalization controls
The Low and High frequency controls are similar to the bass and treble controls found
on most stereo systems. optimum tone is achieved by first setting both knobs half-
way; adjust Low and High frequency controls to suit environment.
auxiliary / line Out
connect speaker line to navy line out connector of the amplifier. For maximum power
transfer and to avoid amplifier overload, be sure that the total impedance of the
speaker line matches the output impedance setting on amplifier. Be sure that speaker
terminals are not shorted together by speaker line connecting cables. Can also be
used for a recording device.
Power Supply 12V dc Operation
Connect a 12 volt rechargeable battery 5 Amp (not included) to the battery input con-
nector located on the panel of the amplifier (using 6' battery cable). Be sure that the
positive pole of battery is connected to the white wire terminal (+) and the negative pole
to the Brass wire (–). When lectern is plugged into a standard wall outlet, the battery will
automatically recharge. Green indicator light illuminates during recharge mode.
