Bought new and barely used. Works flawlessly. Smoke Free Home.
Also have two matching KLIPSCH Speakers Towers, being sold separately to go with the Mc Intosh.
All functions work perfectly. See photos. Case in perfect condition. Just line crease on the top left corner of the glass. Purely cosmetic.
the MA6500 incorporates premium McIntosh technologies – including Power Assurance and Silent Electromagnetic Switching – as well as several features that facilitate system integration and expansion.
EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM. Power Assurance is a collection of technologies that enhance performance and reliability and protect the amp and the loudspeakers.
Power Guard® clipping protection. Power Guard ensures that the amplifier will always deliver full power without causing clipping distortion. If an amplifier channel is overdriven, Power Guard automatically reduces the input volume just enough to keep distortion below 2% and prevent any clipping distortion. Thanks to an optical resistor, Power Guard acts literally at the speed of light, producing absolutely no audible side effects. An amplifier with Power Guard will actually deliver clipping-free output well above its rated power.
Sentry Monitor® current protection. Sentry Monitor continually senses the voltage and current of the output stage and confines it to a safe limit. Sentry Monitor does not limit power output. Thermal Cutout. If the cooling air is blocked and the power transistors become too hot,
thermal cutouts protect against overheating until the amp cools.
Turn-On Delay. This circuit delays operation for about two seconds after turn-on in order to
avoid any pops or thumps generated as other equipment turns on.
Soft Start inrush protection. Thermistors in the power transformer act as a cushion against
inrush current, eliminating component stress during turn-on. Soft Start is one of many design details that contribute to the remarkable longevity of McIntosh equipment.
ILLUMINATED PEAK-RESPONDING METERS. McIntosh meters respond 95% full scale to a single-cycle tone burst at 2kHz. Response is almost 10-times faster than a professional VU meter.
