FUNCTION DESCRIPTION 1. Power Switch Button Control AC power supplier, the power indicator lights up when “on”, indicating that the power supply is connected ; the power indicator is switched off when“off ”, indicating that the power supply is disconnected. 2.
CH1, CH2, CH3, CH4, CH5 channel constant voltage 100V can be selected to meet the requirements of different partition broadcasting. Note: The panel structure and function of FPA-801U/1501U two-sensitivity product amplifier are the same. The panel structure and function of FPA-2501U/3501U teaching product amplifier are the same, like FPA-801U/1501U/2501U/3501U, the FPA-12001U has a different structure and model for the amplifier panel.

10. Fan Note: The rear plate structure and function of FPA-801U/1501U are the same, but the output attact rate is different. The plate structure and function of FPA-2501U/ 3501U are the same, but the output attact rate is different. The function of FPA-12001U is the same with FPA-801U/1501U/2501U/3501U,but the rear plate structure and output attact rate is different.
OPERATION 1. Check that all connections are correct and the backplate voltage is the same as the mains voltage. 2. Check that the audio output voltage is equal to the speaker input voltage. 3. Check whether the total impedance of the system is greater than or equal to the norminal impedance of the amplifier.
