MC162
Commentary

A stereo power amplifier with high sound quality while maintaining high reliability through various guard systems.

The power guard function constantly compares the input and output signal waveforms. When a difference of 0.3% or more is detected, the gain is automatically lowered to prevent abnormal operation. A safe overdrive of 14 dB is guaranteed until the output distortion exceeds 2%.
In addition, reliability is enhanced by circuits such as the Sentry Monitor, which protects the output stage, and temperature protection, which prevents overheating and realizes a long life.

High speed is achieved by cascade connection of driver stages.

The input level control on the rear panel allows fine adjustment of each channel.

On the MC162, it is possible to obtain an output of 500W by bridge connection.

The power meter can be turned on/off.
