A stereo power amplifier that achieves high sound quality while maintaining high reliability through various guard systems.
The power guard function constantly compares the input and output signal waveforms, and when a difference of 0.3% or more is detected, the gain is automatically lowered to prevent abnormal operation, and the output distortion is 14 dB safe until it exceeds 2%. Overdrive is guaranteed.
In addition, reliability is enhanced by circuits such as a sentry monitor, which is a protection circuit for the output stage, and temperature protection, which prevents overheating and achieves a long life.
The driver stage is connected in cascade to increase the speed.
The input level control is carried in the rear panel, and the fine adjustment of each channel is possible.
With MC162, it is possible to obtain an output of 500W by bridging.
The power meter can be turned on / off.
