Performance Features
•Power Output
The MC252 consists of two separate power amplifier chan- nels, each capable of 250 watts into 2, 4 or 8 ohm speakers with less than 0.005% distortion. The two channels can be combined into a single channel with 500 watts into 1, 2, 4, 8 or 16 ohm speakers with less than 0.005% distortion.
•Patented Autoformers
The McIntosh designed and manufactured Output Autoformers provide an ideal match between the amplifier output stage and speaker loads of 2, 4 and 8 ohms. The Autoformers also provide perfect DC protection for your valuable Loudspeakers.
•Patented Power Guard
The patented McIntosh Power Guard Circuit prevents the amplifier from being over driven into clipping, with its harsh distorted sound that can also damage your valuable Loudspeakers.
wiring and protection devices.
•Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MC252 are peak responding, and indicate the 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 MC252 will be retained for many years.
