Amplifier Operating Instructions
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 con- nections 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.
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”.
One auxiliary input is provided for radio tune; tape recorder, CD player or multimedia equipment. Output level is adjusted by the auxiliary volume control.
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 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
connector located on the panel of the amplifier (using 6' battery cable). Note the
positive line is equipped with an in-line fuse, as this is the only polarity identifier. Be
sure that the positive line (in-line fuse) is connected to the positive pole of the
battery (Red terminal) and the negative line (no fuse) is connected to the negative
pole (Black terminal). When lectern is plugged into a standard wall outlet, the
battery will automatically recharge. Green indicator light illuminates during
Set Mic volume control on lowest when turning unit on.
Ensure correct polarity for D.C. supply connections.
Reverse connections will blow the fuse and may damage internal circuitry.
Always replace fuse with specified rating.
