Oklahoma Sound 111PLS Power Plus Floor Lectern

Before operating the amplifier, be sure you fully understand all instructions and features of the amplifier. DO NOT turn the amplifier on until all input and output connections have been made. NEVER replace fuses unless power is off. 

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 channels, 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. 

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. 

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 recharge mode. 

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.
