McIntosh is one of the most dependable brand names when it comes to high-end audio systems. For years the brand has been recognized by audiophiles throughout the world as equipment that delivers clear and consistent quality in music. McIntosh is probably best known for its amplifiers and preamps, but the company produces many other components and parts for stereo and home theatre.
What are the specs for the McIntosh MA 7900?
What else to know about the McIntosh MA 7900?Now you can take advantage of traditional McIntosh standards of excellence in the MA7900 Integrated Amplifier. The Power Amplifier section of the MA7900, 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 connections for various input sources and may also be used to drive an external Power Amplifier(s). The MA7900 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.” Introduction Performance Features • Power Output with Patented Autoformer The MA7900 consists of a 200 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. 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 Loudspeakers. • Sentry Monitor and Thermal Protection McIntosh Sentry Monitor power output stage protection circuits ensure the MA7900 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 1 ThermalTrak™ and ON Semiconductor are trademarks of Semiconductor Components Industries, LLC Electromagnetic Switches on all inputs and operating functions for reliable, noiseless, distortion free switching. There is a Balanced Input for connection of a source component. • Digital Audio Inputs The MA7900 has Coaxial, Optical and USB Digital Inputs to decode PCM Signals from an external source. The MA7900 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 MA7900 contains two different precision Phono Preamplifier Circuits. One for low output Moving 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 Correction Circuitry utilizes close tolerance resistors and capacitors for an extremely flat frequency response. • Five Band Equalizer The Equalizer Controls provide 12dB of boost or cut at center frequencies of 30, 125, 500, 2,000 and 10,000Hz. There is also an Equalizer Bypass Mode to remove the Equalizer from the Signal Path of any selected input. • Multifunction Fluorescent Display The Front Panel Display indicates source selection, volume levels and setup functions. • Illuminated Power Meters The Illuminated Power Output Watt Meters on the MA7900 are peak responding, and indicate the power output of the amplifier. • PassThru Mode The Automatic PassThru Mode allows the MA7900 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 convenient Turn-On/Off of McIntosh Source Components. The Data Ports together with the supplied Remote Control provide control of McIntosh Source Components connected to the MA7900. • Special Power Supply The large Power Transformer, multiple filter capacitors 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 accomplished by the combination of custom designed Fiber Optic Light Diffusers and extra long life Light Emitting Diodes (LEDs). • Glass Front Panel and Super Mirror Chassis Finish The famous McIntosh Illuminated Glass Front Panel and the Stainless Steel Chassis with Super Mirror Finish ensures the pristine beauty of the MA7900 will be retained for many years.
