Used McIntosh MA6600 Integrated Amplifier for sale
Remote included
 
-----
The MA6600 integrated amplifier teams a very low distortion, full function preamplifier with a potent 200 Watt per channel autoformer-coupled amplifier. The ability to accept an optional AM/FM/HD tuner module, the TM2, enables the MA6600 to become the first stereo receiver offered by McIntosh in over 15 years. The preamplifier stage supports 1 balanced and 7 unbalanced inputs and the input names are user configurable. The Variable Rate Volume (VRV) control with Post Attenuator, a McIntosh innovation, provides exceptionally accurate tracking and very low noise operation. Bass, treble and balance functions are all digitally controlled and adjustable via the MA6600 front panel or IR remote and bass and treble settings are automatically memorized independently for each input selection. All signal routing is accomplished with highly reliable, sealed electromagnetic switches. A ¼” front panel jack accesses a dedicated, low impedance headphone amplifier for use with dynamic headphones. Two switched, unbalanced line outputs are available for multi-zone use. The MA6600 power amplifier utilizes a 2-stage differential-balanced voltage amplifier coupled to a push-pull current amplifier and Output Autoformer. This topology exhibits extremely low noise and distortion along with high current capability and is designed to drive a wide range of loudspeakers to sound their very best. The output Autoformer enables the MA6600 to respond with full rated power and low distortion regardless of the load connected and delivers 200 watts per channel into 8, 4 or 2 ohms.

EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM
A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.
 
POWER GUARD®
A waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion.
 
ELECTRONIC SWITCHING AND BALANCED CONNECTIONS
The preamplifier uses Logic Circuits controlling Electromagnetic Switches on all inputs and operating functions for reliable, noiseless distortion free switching. There are two Balanced Inputs for connection of source components and a Balanced Preamplifier output for driving an external Power Amplifier
 
POWER CONTROL AND REMOTE CONTROL
The power control output connection provides convenient Turn-On/Off of McIntosh Source components. The Data Ports together with the supplied Remote Control provides control of McIntosh Source components connected to the MA6600.
 
WATTMETER
Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy.
