M-10X

7.2 CIRCUIT DESCRIPTION
Use a wide range linear circuit of A-607R series for voltage stage, and use HEX POWER MOSFET for output stage.
This circuitry eliminates source resistance, and reduce power loss in large amount with super low capacity resistor of output stage device and realize the low generation of heat, low source voltage. This circuitry eliminates source resistance and listing electric coil, and achieve the damping factor that is flat with band (20Hz - 20kHz).

NOTE: The protection function will operate in case of internal amplifier malfunction or in case of external causes such as static electricity or speaker terminal short circuits. When the protection function operates, the POWER indicator flashes, and the unit goes out into standby mode. If this occurs, check the speaker terminals and speaker cords to make sure they are not shorted, then press the STANDBY/ON button to turn on the unit. If the protection function then operates again, unplug the power cord and contact a service center.

1 Main power ( � OFF/ _ ON ) button
If the button is OFF (�), the power of the amplifier is shut off and the STANDBY/ON button on the amplifier does not function. Pressing the main power button will turn the amplifier ON (_).

2

STANDBY/ON button
Press to switch the amplifier ON or into STANDBY mode.

3 STANDBY indicator
Lights when the amplifier is in STANDBY mode. (Please note that this amplifier consumes a small amount of power (1 W) during the standby mode.)

4 POWER indicator
Lights when the power is switched on.
