Other MA12000 features include:

• Power Guard^® that monitors the output signal for over driving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers
• Our fuse-less short-circuit protection circuit Sentry Monitor^™ that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal
• A pair of peak responding, trademarked “McIntosh Blue” Watt meters that indicate the real time power output of each audio channel
• McIntosh Monogrammed Heatsinks^™ which are connected to advanced high current output transistors that minimize thermal equilibrium lag (or warm-up) time and help keep the MA12000 running cool
• Home Theater PassThru that allows for seamless integration into a home theater system
• Our patented Solid Cinch^™ speaker binding posts that easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables to your speakers
• A discrete, eight-band tone control that allows for advanced manual analog adjustment of your favorite recordings
• High Drive headphone amplifier with Headphone Crossfeed Director (HXD^®) which can bring an added dimension to headphone listening
• Power Control to send power on/off signals to connected McIntosh components for easy system power up and shutdown
• Doubling of filter capacity compared to our other integrated amplifiers for even better low frequency performance
• The latest audio-grade circuit components to deliver the best sound possible
• Powerful control microprocessors to improve overall system operation
• Easy operation via front panel controls or the included comprehensive remote control
