Ground

Audio/Video Control Center or Preamplifier. If any addi- tional McIntosh Power Amplifiers are part of the system, a delayed Power Control Output Trigger is available. This delayed trigger reduces the strain on the house’s electrical wiring and protection devices.

Now you can take advantage of traditional McIntosh stan- dards of excellence in the MC501 Power Amplifier. The 500 watt high current output will drive any high quality Loudspeaker System to its ultimate performance. The MC501 reproduction is sonically transparent and abso- lutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Performance Features

•Power Output

The MC501 is a Power Amplifier with a capability of 500 watts into 2, 4 or 8 ohm speakers with less than 0.005% distortion.

•Full Balanced Quad-Differential Circuitry

The MC501 is fully balanced from inputs to outputs. It consists of two matched power amplifiers operating in push-pull with their outputs combined in a McIntosh Autoformer. The double balanced configuration cancels virtually all distortion.

•Patented Autoformers

The McIntosh designed and manufactured Output Autoformer provides an ideal match between the amplifier output stage and speaker loads of 2, 4 and 8 ohms. The Autoformer also provides perfect DC protection for your valuable Loudspeaker.

•Patented Power Guard

The patented McIntosh Power Guard Circuit prevents the amplifier from being over driven into clipping, with its

•Balanced and Unbalanced Inputs

Balanced connections guard against induced noise and al- low long cable runs without compromising sound quality.

•Illuminated Power Meter

The Illuminated Power Output Watt Meter on the MC501 is peak responding, and indicates the true power output of the amplifier. The Peak Watt Hold Mode allows the meter to temporarily stay at the highest power output and then slowly decay. The Front Panel Meter Illumination may be switched Off at any time.

•Fiber Optic Solid State Front Panel Illumination The Illumination of the Front Panel is accomplished by the combination of custom designed Fiber Optic Light Diffus- ers and Light Emitting Diodes (LEDs). This provides even Front Panel Illumination, together with the extra long life LEDs.

•Glass Front Panel and Super Mirror Chassis Finish The famous McIntosh Illuminated Glass Front Panel with a three dimensional look and the Stainless Steel Chassis with Super Mirror Finish ensures the pristine beauty of the MC501 will be retained for many years.
