McIntosh MC162 380,000yen(around the 1998 time)

Description
 
Stereo power amplifier which attained high-quality sound-ization maintaining a high robustness by various guarding systems.

If the signal wave form of an input/output is always compared and 0.3% or more of difference is detected by a power guarding functionality, by the time it will lower gain automatically, it will prevent an unusual operation and distortion of an output will exceed 2%, a safe over drive of 14dB will be secured.
In addition, circuitries, such as a sentry monitor which is a protection network of an output stage, and a temperature protection which prevents overheat and realizes a long life, are raising the robustness.

The driver stage was made into cascade connection and is high-speed-ized.

The input level control is carried in the rear panel, and a fine tune of each channel is possible.

The output of 500W is able to obtain by bridge connection at MC162.

A power meter can be turned on and off.
