Other McIntosh features included in the MA8950 are:

• Power Guard^® that continuously monitors input and output signals and can dynamically adjust input levels to ensure maximum output while avoiding harsh sounding distortion and clipping that could damage your speakers
• Our fuse-less short-circuit protection technology Sentry Monitor^™ that disengages the output stage before the current can exceed safe operating levels and then resets automatically when operating conditions return to normal
• McIntosh Monogrammed Heatsinks^™ that are made from high quality materials with excellent thermal conductivity and heat dissipation properties
• Home Theater PassThru that allows for seamless integration into a home theater system
• High Drive headphone amplifier with Headphone Crossfeed Director (HXD^®) which can bring an added dimension to headphone listening
• A discrete, five-band tone control that allows for advanced manual analog adjustment of ±12dB in 2dB increments of your favorite recordings at frequencies of 30Hz, 250Hz, 500Hz, 2kHz, and 10kHz
• Power Control to send power on/off signals to connected McIntosh components for easy system power up and shutdown
• Gold-plated speaker binding posts that prevent corrosion to ensure a quality signal is sent over your speaker cables to your speakers
