Mcintosh MC352 Power Amplifier

The stereo amplifier of the legendary American company McIntosh MC 352. 350 watts of power will cope with any speakers. A classic American sound that has so many connoisseurs. The device was built in 1999, when the Macintosh was still playing. Everything is in perfect condition.

In the MC352, the linearity of voltage and current amplification is strictly controlled at each stage.
For this reason, 16 units of each element with excellent performance and stable current gain have been selected for the output transistor. In addition, feedback is applied to the two balance stages before the amplification stage, so that the load impedance of each amplification stage becomes constant depending on the input signal level, and the linearity of the impedance is improved.
In addition, by using high-precision parts with small fluctuations in capacitors and resistors, as well as by reducing cross-distortion with an automatic tracking and offset system, linearity at low output is also improved.

Using an output transformer, the output transistor can always operate in the best condition, since optimal impedance matching is possible for any type of speaker load.
In addition, the MC352 has improved dynamic performance and stability thanks to the use of the first balanced winding of the Macintosh.

A rigid stainless steel chassis is used for the chassis, the power transformer is placed in the center, and the output autoformer is spread out on the left and right sides for a monoblock design with reduced crosstalk.
The power transistors are mounted on a well-cooled 2,800-square-inch radiator, eliminating the need for cooling fans.

Equipped with a unique power protection system.
The shape of the output signal is compared with the input signal. When the total harmonic distortion due to overload exceeds 0.3%, the power protection indicator lights up. When the distortion increases further, the power protection circuit is triggered to control the input signal.
In addition, the MC352 uses an auto-shaper of the output signal so that direct current does not damage the speakers in principle. In addition, even if the speakers are shorted or subjected to an ultra-low resistance load, the Sentry Monitor circuit is triggered to protect the power stage.

It is equipped with a large peak power indicator with Macintosh Blue backlight.
This meter also has a light off position.

Uses a gold-plated speaker connector.

Equipped with a temperature protection that disables the input when the sensor detects overheating.
