AMPLIFIER OPERATING INSTRUCTIONS
Operating Precautions
Before operating the amplifier, be sure you fully understand all instructions and
features 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 multi-
media 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 halfway; 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 imped-
ance of the speaker line matches the output impedance setting on amplifier.
Be sure that speaker terminals are not shorted together by speaker line con-
necting 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 connector 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.
Precautions
• Set Mic volume control on lowest when turning unit on.
• Insure correct polarity for D.C. supply connections.
• Reverse connection will blow the fuse and may damage internal circuitry.
• Always replace fuse with specified rating.

1) Disconnect A/C wall plug.
2) Remove 2 side screws one on each side panel under podium top.
