MC1201 Power Amplifier
Overview
For over fifty years, McIntosh Laboratory has been building the finest high end audio components - including an amplifier in each generation designed to be "the best amplifier in the world." Now we have a new contender for the world title - the MC1201, a 1,200 watt Mono Power Amplifier.
The MC1201 amplifier is fully double balanced from input to speaker output. Two matched amplifiers with complimentary balanced circuitry operate in a PUSH-PULL configuration. Their outputs are combined in a balanced "OUTPUT AUTOFORMER". The resulting double balanced configuration cancels virtually all distortion. This circuit is ONLY possible with the exclusive "McINTOSH OUTPUT AUTOFORMER".
All critical circuits employ precision metal film resistors and film capacitors with low absorption dielectrics. Transistors are selected for constant current gain across their entire operating range. Every stage of voltage or current amplification is designed for the best linear performance. All of the above guarantee the lowest distortion.
High power amplifiers draw high current from the AC power line. Most owners desire that there be one power switch for the whole audio system. The MC1201 is equipped with a circuit that provides remote POWER CONTROL from your McIntosh preamp or control center.
The MC1201 also has a remote POWER CONTROL OUT jack. The POWER CONTROL signal from this jack is delayed by a fraction of a second so that the turn on power surge of the next power amplifier occurs at a later time. This helps prevent power circuit overload that could pop circuit breakers or blow fuses, a very important feature in a high power Home Theater System employing all MC1201 Power Amplifiers.
The tremendous peak output power capability of the MC1201 has made the addition of a circuit that regulates the brilliance of the panel and meter illumination necessary. When there are high power output demands the line voltage may sag, however this new circuit prevents the lights from dimming.
The MC1201 hides its glorious sound and high power behind the famous glow of the McIntosh 1/2-inch thick illuminated glass panel. Its green nomenclature and the soft blue light of the wattmeter make it the world's most attractive power amplifier. After 50 years of masterful engineering, McIntosh really knows how to build a power amplifier.
