McIntosh MA 6200 – High End Stereo Equipment We Buy

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 else to know about the McIntosh MA 6200?

"The MA 6200 is another fine expression of stereo engineering and craftsmanship by McIntosh. The flexibility and high performance found in the MA 6200 are a result of direct customer contact, continued market analysis and aggressive, advanced research. The McIntosh reputation for excellence in performance, flexibilty, quality and reliability comes from extensive testing leading to the careful selection of materials and circuit components combined with dedicated craftsmanship.

MA 6200 Features

Seven Different Program Sources
The input switch selects from five different sources or you can choose to listen to either of two tape recorders at the push of a button. Electronic Active Filter Elements "Active filter" technology is used to generate the equivalent of the inductors normally used in equalizer filters. This eliminates the hum pickup of inductance non linearity than often occurs from conventional inductors.

"LED" Function Indicators
System status is indicated by long life "LED" indicators

Turn-on Transient Elimination Circuits
Speaker outputs are connected only sfter power supplies and circuits have stabilized eliminating turn on thumps or clicks

Auto Turn On/Turn Off
Harmonic distortion does not exceed 0,05% when measured from the phono input to the speaker output from 20 Hz to 20 kHz at all power levels from 250 mW to full rated output.

Auto Turn On/Turn Off
Power to the entire stereo system can be controlled from either the front panel power switch or the turntable's power switch. A current sensing relay connected to the turntable AC power outlets is controlled by the turntable power switch. The relay, in turn controls the AC power to the remainder of the system.

Speaker switches for Three Sets of Speakers
Three sets of loudspeaker may be used one at a time, two together, or all three simultaneously.

Speaker Protection Circuits
Loudspeaker are protected from burnout by the Power Guard circuit and also by other circuit that instantaneously disconnect the speakers in he presence of DC on the output.

Precision Step Attenuator Volume Control
Ideal volume control tracking accuracy and noise free performance are two of the considerable benefits of the McIntosh Precision Step Attenuator. It is a thirty-two step, 70 dB range control with unheard of tracking accuracy within 1 dB. The extreme accuracy is obtained through special electronically controlled resistance element trimming. The accuracy and quiet operation are maintained because the switch commutator touches, only the switch contact pad and not the precision resistor elements.

True Loudness Compensation
In the past, loudness controls have typically used simple passive circuits connected to a portion of the rotation range of the volume control. As a consequence, loudness compensation accuracy was dependent on many variables such as speaker efficiency, amplifier gain and differences in input level. The MA 6200 loudness control is continuously variable, operates independently of the volume control, and its contour is accurately modeled after the Fletcher Munson family of "Equal Loudness" curves.

Five Band Program Equalizer
Five separate controls permit individual musical spectra shaping in two octave segments to satisfy personal preference or program limitations. There is 12 dB plus or munus control at center frequency of the individual segments. The center frequency are 30, 150, 500, 1500 and 10,000 Hz.

Dual Tape Monitor And Tape Copy Switches
Two tape recorders can record simultaneously from the program being listened to or you may record from one to the other without interfering with the "Listen" program.

Power Guard Indicator and Protection Circuit
Two red power quard indicators indicate when the power amplifier has reached full output. At this point the power guard circuit begins to control amplification dynamically so that you will not hear the harsh distorted sound of square wave clipping. In addition your speakers are protected from burnout.

Very Low Impedance Phono Preamplifier
A new state-of-the-art. Technology operational amplifier is arranged in a low impedance circuit to reduce noise to the lowest achievable level. The circuit follows the RIAA equalization curve.

Preamp Output - Power Amp Input Connections
Back panel connections provide the ability to insert room equalizers, reverberation units or other signal processing devices.

Low Noise High Performance Op-Amps
New technology low noise operational amplifiers give lower noise and greater band width than conventional devices." - 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.

Other McIntosh Products We Often Buy

Typically, StereoBuyers purchases mostly used amplifiers, especially the vintage amps and high-end McIntosh models such as the MC202 or MC252, and the C220 preamp, for example. We have also purchased many pre-owned tuners from McIntosh over the recent years, including the MR67 and MR78 models, for example.

StereoBuyers has purchased tens of thousands worth McIntosh brand equipment since 2014, with individual buys ranging from $100 to well over $50,000. If you are moving, ready to upgrade, or have McIntosh equipment you do not or will not be using, why not contact us today to find out if it is worth good money?
