CD Transport

s distinctions among CD players grow ever finer, those seeking the ultimate
in sonic purity find salvation through separation – one box for the transport,

A

one box for the converter. The MCD751’s advanced optomechanical design makes
it the last CD transport you may ever need. It connects directly to the McIntosh
MDA700 D/A Converter or to any DAC-equipped component with a digital input.

Featured Technologies

PRECISION TRANSPORT MECHANISM. The Vibration-Free Rigid Disc Clamping System uses
a CD-size, die-cast aluminum overhead turntable with a precision helicoid clamp that provides
superior rotational stability. The motor bridge and clamping system are made of high-density
material containing polyester fibers and ceramic powders to suppress spurious vibrations.

DIGITAL SERVO CONTROL MOTORS. The Brushless Hall Effect drive spindle motor for disc
rotation and the linear laser assembly motor ensure the integrity of the digital data.

DUAL OUTPUTS. The two digital outputs (coaxial and optical) provide connection flexibility
and also can be used to feed two D/A converters simultaneously.

DATA IN/OUT. These allow the MCD751 to operate the MDA700 D/A Converter via remote
and to connect to other McIntosh system components.

REMOTE POWER CONTROL. This enables the MCD751 to turn on/off with other McIntosh
system components.

REGULATED POWER SUPPLY. A fully regulated power supply with a special power transformer
ensures stable, noise-free operation even when the power line varies.

About the MCD751 Companion Products

The McIntosh products shown at right are logical companions for the MCD751. Separate literature
is available. Check with your McIntosh dealer for any late additions. McIntosh speaker systems
are also covered in detail in separate literature.

MDA700 D/A Converter. The MDA700 features a breakthrough balanced/parallel design that
uses eight of Burr-Brown’s best D/A chips for music reproduction of unparalleled clarity. With
four digital inputs and automatic selection of the correct sampling frequency, the MDA700 will
ensure uniformly excellent sound with the MCD751 and other digital sources.

MX132 A/V Control Center + Processor. The MX132 includes digital inputs and uses a highly
refined 24-bit D/A converter, requiring only the MCD751 transport for superb CD performance.

MSD4 Surround Decoder. The MSD4 contains the same highly refined DAC as the MX132.

As seen on the inside surface of this demonstration piece,
the screening process for a McIntosh glass panel entails as
many as 12 individual layers.

MSD4 SURROUND DECODER

The glass panels are cut using a computer-controlled
high-pressure water jet.

ost consumer electronics products are necessarily viewed
as short-term investments because either they don’t last

M

or they quickly become obsolete in some way. Coincidentally,
manufacturers supply a steady stream of “new-and-improved”
products that you can buy. Again.

Behind every McIntosh is a fifty-year heritage of excellence,

proudly carried forward by every employee. No production

lines, no “price-point” engineering, no planned obsolescence.
McIntosh equipment is made to sound better and last longer.

When McIntosh products are presented to customers, the
criteria they have been conditioned to overlook – reliability,
longevity, craftsmanship, ease-of-use, adaptability, pride of
ownership – suddenly leap to the top of their list.

The choice becomes clear: There is nothing like a McIntosh.
