700 SERIES 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.
Auxiliary Input
One auxiliary input is provided for radio tuner, tape recorder, CD player or multi-media equip-
ment. 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 additional 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 speak-
er 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). 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
