MA6600 Integrated Amplifier Features

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 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.
