Page 7: Introduction
Some speaker designs have impedance characteristics that may dip to as low as 1 or 2 ohms at certain frequencies. It is possible for the MC150 to deliver as much as 50 amperes peak current into these lower impedance loads. -

POWER OUTPUT METERS FRONT The MC150 power output meters respond 95% full scale to a single cycle of a 2000Hz PANEL tone. Both voltage and current are electronically measured and fed to a special circuit that accelerates the pointer movement in the upward direction. When the meter pointer reaches its peak, it is time stretched to pause just long enough to be read, and then drops. -

POWER/OFF-REMOTE/ ON Turn on the MC150 power by turning the front panel POWER switch to ON. You can also turn the MC150 power on with a Power Control signal from an accessory Mclntosh com- ponent or Control Center that includes a Power Control Out. - Page 10 HOW TO CONNECT OUTPUTS The Mclntosh output circuit, superior in its performance, demands a superior method of coupling the amplifier output to the loudspeaker load. The MC150 incorporates Mclntosh designed and manufactured Autoformers to insure peak performance and protection, as well as outstanding compatibility between amplifier and speakers.
- Page 11 If the actual load impedance of a speaker is lower than the specified impedance, par- ticularly at different parts of the frequency range, it will cause no problems. The high current output capacity of the MC150 will produce the extra current necessary to properly drive the speaker under these conditions.
- Page 12 Control Center or Preamplifier. POWER CONTROL, IN/OUT The MC150 AC power can be turned on and off by a control signal fed to the POWER CONTROL IN connector from the POWER CONTROL OUT connector on compatible Mclntosh products. The MC150 POWER CONTROL OUT jack will feed the same power control signal out, delayed 0.2 seconds, to turn on and off another accessory component with a compatible...

Page 14: Technical Description
The secret to this performance will sound very simple, but it is more difficult to carry out than it may seem. The principle used in the design of the MC150 was to arrange every stage of voltage or current amplifications to be as linear as possible. - Page 15 The unequalled expertise of Mclntosh in the design and manufacture of output auto- formers is legendary in the Hi Fi industry. In the MC150, they provide proper matching for 2, 4 and 8 ohm loads. They protect your speakers from damage in the event of an output transistor failure, provide low distortion power transfer at frequencies well beyond human hearing and deliver peak output currents in excess of 53 amperes.
- Page 16 Four large heatsinks provide cooling for the 12 output power transistors. The mechanical and electrical design of the MC150 is the result of the many years of engineering and manufacturing experience held by the staff at Mclntosh This "Know How", the meticulous attention to design and production details, makes the MC150 one of the finest amplifiers ever produced by Mclntosh Laboratory, Inc.
