Introduction
Now you can take advantage of traditional McIntosh stan- dards of excellence in the MA7000 Integrated Amplifier. The Power Amplifier section of the MA7000, with a power output of 250 watts per channel, will drive a pair of quality Loudspeakers to a high level of performance. The flex- ible Preamplifier section provides connections for various input sources and may also be used to drive an external Power Amplifier. The MA7000 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”
Performance Features
• Power Output with Patented Autoformer
The MA7000 consists of a 250 watts per channel stereo Power Amplifier with less than 0.005% distortion. The McIntosh designed and manufactured Autoformer allows connection of 2, 4 or 8 ohm Loudspeakers.
•Electronic Switching and Balanced Connections The Preamplifier uses Logic Circuits controlling Electro- magnetic 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 Guard
The patented McIntosh Power Guard circuit prevents the amplifier from being overdriven 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 MA7000 will have a long and trouble free operating life.
• Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MA7000 are peak responding, and indicate the power out- put of the amplifier.
• Power Control and Remote Control
The Power Control Output connection provides convenient
• Special Power Supply
The large Power Transformer, multiple filter capacitors and regulated Power Supply ensures stable noise free operation even though the power line varies.
•Fiber Optic Solid State Front Panel Illumination The even Illumination of the Front Panel is accomplished by the combination of custom designed Fiber Optic Light Diffusers and extra long life Light Emitting Diodes (LEDs). The glass Front Panel ensures the pristine beauty of the MA7000 will be retained for many years.
