DROTECTION CIRCUIT FOR OCL POHER AMPLIFIER V ,
AND SPEAKER
. Over current detecting circuit
operation at the time of over load, such as a
speaker terminal short.
. DC voltage detecting circuit
Operation at the time when positive or negative DC
voltage (il.lV of detection level) has generated
at output terminals.
. Muting circuit
Transient noise protection when power is ON-OFF.
. Relay driver circuit (Drive current of 130mA at Max.)
. Operation by dual power supply.
