McIntosh MC402 power amplifier

McIntosh MC402

Producing a minimum 400 watts per channel in stereo, 800 watts in mono, the MC402 delivers power that is fully balanced from input to speaker output. The extraordinary quad-differential design of the MC402 actually consists of four complete amplifier circuits. Each channel contains two amplifier circuits, each the mirror image of the other, whose outputs are combined in the unique McIntosh Output Autoformer® resulting in totally balanced operation from input to speaker output and the cancellation of virtually all noise and distortion.

The exclusive McIntosh Output Autoformer® is a handcrafted matching device that provides an ideal impedance match for all speaker types regardless of their rated impedance. Any departure from an optimum impedance match increases stress on the amplifier which threatens a rise in distortion as well as a reduction in the life expectancy of the amplifier. McIntosh Output Autoformers® enable the MC402 to operate at maximum efficiency and to always deliver full power, without stress, to any type of loudspeaker.

Exclusive McIntosh

Power Assurance System - A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.

Power Guard - A waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion.

Sentry Monitor - Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level – resets automatically.

Thermal Sensors - Protects against overheating if cooling air is blocked and output transistors become too hot.

DC Failure Protection - Protects speaker against output circuit failure. Any DC current that appears in the output is shunted to ground by the output autoformer.

Exclusive Double Balanced Circuity - Each channel of the MC402 consists of two balanced power amplifiers operating in push-pull with their outputs combined in a McIntosh Autoformer. This double balanced configuration from input to output cancels virtually all distortion

Output Autoformer - Unique McIntosh technology delivers the full rated amplifier output with the least possible distortion into loudspeaker impedances of 2, 4, or 8 Ohms; you get all the power you paid for and the freedom to choose any loudspeaker.

Wattmeter - Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy.

Turn-on Delay - Delays operation for about two seconds after turn-on, to silence any pops or thumps generated by other equipment.

Soft Start Inrush Protection - Eliminates component stress during turn-on. Theristors in the power transformer act as a cushion against inrush current

Balanced and Unbalanced Inputs

Balanced connections guard against induced noise and al-

low long cable runs without compromising sound quality.

Illuminated Power Meters - The Illuminated Power Output Watt Meters on the MC402 are peak responding, and indicate the true power output of the amplifier. The Peak Watt Hold Mode allows the meters to temporarily stay at the highest power output and then slowly decay. The Front Panel Meter Illumination may be switched Off at any time.

Fiber Optic Solid State Front Panel Illumination The Illumination of the Front Panel is accomplished by the combination of custom designed Fiber  Optic Light Diffusers and Light Emitting Diodes (LEDs). This provides even Front Panel Illumination, together with the extremely long life LEDs.

Glass Front Panel and Super Mirror Chassis Finish - The famous McIntosh Illuminated Glass Front Panel with a three dimensional look and the Stainless Steel Chassis with Super Mirror Finish ensures the pristine beauty of the MC402 will be retained for many years

McIntosh LS360 loudspeakers

 McIntosh LS360

At just more than four feet tall, the magnificent LS360 is the flagship of the Academy Series. Like the CS350, its five tweeters are wired to produce a Bessel Function array. The individual tweeter amplitudes and phase relationships are adjusted so that the array acts as a high frequency point source with a broad dispersion pattern. In addition, the array greatly increases power handling for high frequencies. Two 10-inch LD/HP® woofers and an 8-inch LD/HP ® midrange round out the driver complement. This two bass ports are flared at both ends to form a natural horn and minimize air noise. The tweeters are mounted on traditional McIntosh screened black glass. Natural Cherry, red Cherry, and Black Ash finishes. Exotic woods and finishes available by special order (Piano Black).

The new McIntosh loudspeaker line results from the most ambitious speaker development project in McIntosh history. Never have McIntosh speakers and electronics enjoyed such harmony of quality, performance, and purpose.

With the McIntosh loudspeakers, from the very beginning these models have been designed for low-distortion performance, thanks to patented LD/HP® drivers and unique arched bridge truss cabinet construction. Music benefits from smooth, extended response without the coloration and fuzzy imaging caused by driver distortion and cabinet vibrations. Movie sound benefits from high power handling and fast, clean dynamic response, from the high-output LD/HP drivers.

McIntosh speakers are a true family, sharing a common tonal quality that allows for great configuration flexibility. Virtually any combination of speakers can be used in multichannel applications. High-end loudspeaker in particular are often characterized by just one aspect of their performance. It could be bass response, treble transparency, depth of image, cosmetic appearance, or even price. In all of its products, however, McIntosh seeks balance, and so is the case with speakers. McIntosh speakers certainly have an extremely smooth and broad frequency response, and they do “measure” well in front of a microphone and spectrum analyzer. But in the final analysis, they are distinguished by their sheer musicality, which can only be measured by listening.

LD/HP® Drivers

In LD/HP driver, a pair of aluminum shorting sleeves makes the magnetic field more symmetrical and reduces distortion. The sleeves also lower the impedance of the voice coil, permitting greater current flow and hence higher output levels.

McIntosh XL10 loudspeakers

The XL10 is a three way loudspeaker system with two active drives and one passive. It can accurately reproduce a three dimensional sound space with smooth response. The McIntosh anechoic chamber provided the ability to adjust response, amplitude and arrival time. As a result, the XL10 can recreate stereo sound for you with full depth and spaciousness.

The XL10 has a one inch dome tweeter, a carefully matched, high power handling eight inch woofer and a ten inch controlled mass passive radiator. It has an extensive and meticulously designed crossover network.

The eight inch woofer has a copper wire voice coil wound on a black anodized aluminum voice coil form. This form, radiates heat effectively. Excessive heat is always destructive to electronic circuit elements so this design feature is very important to the long life of the XL10. the windings are attached with a high temperature, thermal setting adhesive.

The voice coil assembly is joined directly to the rigid cone. It moves in the magnetic field of a critically sized magnet and magnet structure. This assembly is cantered and suspended in the magnetic field by a special cloth spider. The compliance of the spider is controlled by the careful impregnation of the cloth with phenolic resins. Diligent engineering, decades of experience and continuous testing determined the selection of the right mass of the cone assembly to ideally match the energy capability of the magnetic structure. The total of the cone, voice coil, and suspension assembly is attached to the speaker basket with a critically formed, closed cell urethane surround.

The inch passive radiator has an accurately adjusted moving mass and compliance which complements the design characteristics of the eight inch woofer and the volume of air in the Xl10 enclosure. In the lower bass frequency range, this rigid cone is driven in phase, acoustically, by the woofer, extending the system acoustic output. The cone assembly is attached to the speaker basket by a special cloth spider and a closed cell surround.

The one inch high frequency dome tweeter is made of a specially formulated textile which is driven by a copper wire voice coil wound on a high temperature voice coil form. The assembly is centered and suspended in the magnetic field by a special surround. Both dome and surround are coated with a proprietary material to make an air tight seal. The surround is connected to an intermediate ring which is fastened to the magnet assembly.

The frequency directing crossover network directs all musical information below a designed frequency to the woofer and all frequencies above to the dome tweeter. The McIntosh crossover network, however, has additional tasks to perform. It must smooth the response in the active area of sound. A loudspeaker that can deliver ideal depth, spaciousness and three dimensional sound space, requires a crossover network that is a product of particular and comprehensive examination of the multitude of mathematical potentials to include the exact circuit components in order to provide smoothest response and correct arrival time. Exhaustive measurements in the McIntosh Full Sized Anechoic Chamber assures the exactness of the circuit and of the components selected for the crossover.

McIntosh C-30 preamplifier

The McIntosh C 30 Preamplifier

McIntosh continues research into user desires consistent with high quality music reproduction.

Engineering that is aggressively inquisitive in the search for better ways to bring these user dictated requirements to a technologically superior, innovative and clearly useful result.

Appearance design that has long life, complements the living style, is complimentary to the owner, and is made of materials, whose characteristics permit a like new always appearance.

Easy, to operate; the unique McIntosh designed panels are always easily readable in your choice of home lighting. They are obviously designed by human beings for human beings.

Manufactured of carefully specified and selected component parts that have high quality and long predicted life.

Assembled by highly trained craftspeople who are dedicated to quality, accuracy and perfection.

Thorough verification of the desired capabilities and quality of performance by constant and complete setting throughout the entire manufacturing process.

Here is the latest advanced technology instrument that adds to the already formidable McIntosh reputation.

Five separate tone shaping controls provides musical spectra tone shaping. Each control adjusts two octave band segments to satisfy your personal preference or the demands of the program material. At the detent in the center of the rotation of each control the equalizer circuits are disconnected, completely removed from the operating circuits.

 

Loudness controls in ordinary equipment are usually simple, passive circuits connected to a portion of the rotation range of the volume control. As a consequence, loudness compensation accuracy is dependent on many variables such as speaker efficiency amplifier gain and differences in input level. The C30 loudness control is continuously variable, operates independently of the volume control, and its contour is accurately modelled after the family of "Equal Loudness" curves developed by Drs. Fletcher and Munson.

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.

Headphone loudness is adjusted using the same type of Precision Step Attenuator. The loudness of the program when using headphones is controlled by this front panel control. The control adjusts the output to the headphone jacks only and does not affect the program loudness from the loudspeakers. Then, while wearing the headphones, adjust the headphone level controls to the desired loudness level.

The appearance of a McIntosh speaker eloquently of precision, quality, premier performance and long, trouble-free life. Consider the construction and materials used in the front panel and knobs. Each constituent part is selected for long, wear-resistant life and stable attractive styling. The panel itself is select white flint glass, free from bubbles, flow marks and other faults. It is silk screened on the reverse side with thermal setting epoxy screen inks which practically become a part of the glass. Then it is built into a brightly polished and anodized frame. The knobs used are meticulously machined of solid aluminum then anodized and thermally isolated.

McIntosh MC 2002 power amplifier

Power Amplifier. 

 The MC 2002 amplifier is designed for the Real world of 10 decibel overloads from compact disc players. It combines: 200 watts of extremely low distortion power at 8 ohms; 300 watts of the same power at 4 ohms. The greatest reliability in modern amplifiers to protect your investment. And most important today, design for 10 decibels of overload stress with the greatest Spectral Fidelity.

Spectral Fidelity is one of the most meaningful characteristics of an amplifier. The harmonic distortion and the two tone intermodulation measurements are important criteria in predicting the sonic performance. However to obtain better correlation with human hearing response, we need to know not only the energy in the distortion spectrum, but also the number of discords and their frequency spacing from the desired tones. This is what the Spectral Fidelity testing can do, enlarging the scope of the data and showing its meaning more fully.

Spectral Fidelity Protection

The threshold for human hearing shows a pronounced sensitivity in the region of 1500 Hz. At low levels of music, during pianissimo passages for example, is where we hear most intermodulation discords. But during the periods of sonic overload, this sensitivity characteristic changes. Under this condition, the sensitivity of the human ear becomes more uniform over most of the range of hearing. Thus all of the discords from sonic overload combine to reduce the musicality of instruments and voices, their clarity and definition. This loss of the order, the structure, and harmony, remebered from live musical experience, is frustrating and disappointing to the human psycho=physical hearing phenomenon. This frustration is the major cause of unacceptable  Listening Fatique.

Of all the amplifiers tested for Spectral Fidelity under stress, the McIntosh alone could accept the compact disc overload without exceeding 3/10 of 1% distortion. The others produced high levels of distortion, distortion from 20% to 30%. Some designs blew fuses. Others suffered output stage device failures.
