McIntosh MA6300 Integrated Amplifier - All Analog with Phono Input
Fully tested and working brilliantly.
Includes original double box and remote.
Looks almost new. All meters and lights work as they should.
"Now you can take advantage of traditional McIntosh standards of excellence in the MA6300 Integrated Amplifier. The Power Amplifier section of the MA6300, with a power output of 100 watts per channel, will drive a pair of quality loudspeakers to a high level of performance.
The flexible Preamplifier section provides connections for various input sources and may also be used to drive an external Power Amplifier. The MA6300 reproduction is sonically transparent and absolutely accurate. .
The McIntosh Sound is “The Sound of the Music Itself.”
Some MA6300 Performance Features Include:
• Power Output
The MA6300 consists of a 100 watts per channel stereo Power Amplifier and a sophisticated Preamplifier in one compact unit with less than 0.005% distortion.
• Electronic Input Switching and Balanced Input
Digital Logic integrated circuits drive Electromagnetic switches on all seven inputs and operating functions for reliable, noiseless, distortion free switching. The Balanced Input allows the connection of a source component using long cable lengths, without a loss in sound quality.
• Power Guard
The patented McIntosh Power Guard circuit prevents the amplifier from being over driven into clipping with its harsh distorted sound that can also damage your valuable loudspeakers.
• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection circuits ensure the MA6300 will have a long and trouble free operating life. Built-in thermal protection circuits guard against overheating.
