What else to know about the McIntosh MAC 6700?

"Now you can take advantage of traditional McIntosh standards of excellence in the MA6700 Integrated Amplifier or MAC6700 Receiver. The Power Amplifier section of the MA/MAC6700, with a power output of 200 watts per channel, will drive a pair of quality Loudspeakers to a high level of performance.

The flexible Preamplifier section provides connec- tions for various input sources and may also be used to drive an external Power Amplifier(s).

The MAC6700 tuner circuitry delivers the same exceptional performance as a stand-alone McIntosh Tuner. The MA6700 has provisions for adding an optional McIntosh AM/FM Tuner Module. The Tuner Module can be installed by your McIntosh Service Dealer at any time, usually while you wait.

The MA/MAC6700 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Amplifier Performance Features

• Power Output with Patented Autoformer

The MA/MAC6700 consists of a 200 watts per chan- nel stereo Power Amplifier with less than 0.005% distortion. The McIntosh designed and manufactured Autoformer allows connection of 2, 4 or 8 ohm Loud- speakers. The Power Amplifier uses ThermalTrak1 Output Transistors for lower distortion and cool operation.

• Power Guard

The patented McIntosh Power Guard circuit prevents amplifier clipping and protects your valuable Loud- speakers. • Sentry Monitor and Thermal Protection

McIntosh Sentry Monitor power output stage protec- tion circuits ensure the MA/MAC6700 will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating.

• Electronic Switching and Balanced Connections

The Preamplifier uses Logic Circuits controlling Electromagnetic Switches on all inputs and operat- ing functions for reliable, noiseless, distortion free switching. There is a Balanced Input for connection of source components.

• Digital Audio Inputs

The MA/MAC6700 has Coaxial, Optical and USB Digital Inputs to Decode PCM Signals from an external source. The MA/MAC6700 Up Samples the Digital Signal to 192kHz with 32Bit resolution before the Digital to Analog process begins.

• Moving Coil and Moving Magnet Phono Inputs

The MA/MAC6700 contains two different precision Phono Preamplifier Circuits. One for low output Mov- ing Coil Phono Cartridges with selectable resistance loading, the other is for Moving Magnet Cartridges. Both circuits use the latest designs to provide the lowest possible noise and distortion. The RIAA Cor- rection Equalization Circuitry utilizes close tolerance resistors and capacitors for an extremely flat frequen- cy response.

• Multifunction Fluorescent Display

The Front Panel Display indicates source selection, volume levels, tone adjustments and setup functions.

• Illuminated Power Meters

The Illuminated Power Output Watt Meters on the MA/MAC6700 are peak responding, and indicate the power output of the amplifier.

• PassThru Mode

The Automatic PassThru Mode allows the MA/ MAC6700 to become part of a Multichannel Sound System for DVD-Audio, SACD and Home Theater Movies.

• Power Control and Remote Control

The Power Control Output connection provides conve- nient Turn-On/Off of McIntosh Source Components. The Data Ports together with the supplied Remote Control provide control of McIntosh Source Compo- nents connected to the MA/MAC6700.

• Special Power Supply

The large Power Transformer, multiple filter capaci- tors with 120 Joules of Energy Storage and regulated Power Supply ensures stable noise free operation even though the power line varies.

• McIntosh Custom Binding Posts

McIntosh Patented gold plated output terminals deliver high current output. They accept large diameter wire and spade lugs. Banana plugs may also be used only in the United States and Canada.

• Fiber Optic Solid State Front Panel Illumination

The even Illumination of the Front Panel is accom- plished by the combination of custom designed Fiber Optic Light Diffusers and extra long life Light Emit- ting Diodes (LEDs). The glass Front Panel ensures the pristine beauty of the MA/MAC6700 will be retained for many years." - McIntosh

Brief History of McIntosh

Long mapped-to Binghamton New York – the current headquarters and manufacturing center for McIntosh Labs – not many people know the brand was originally launched outside of the Nation’s Capital in Silver Spring Maryland, in 1949. In 1956, the brand built their original facility in New York, according to the official brand website.
