The McIntosh products shown at right are logical
companions for the MA6900. Separate literature
is available. Check with your McIntosh dealer for
late additions.
MVP841 DVD/CD/Video CD Player. The MVP841
delivers crystal-clear DVD video and outputs
Dolby Digital
®
and DTS
®
surround sound.
MR85 AM/FM Tuner with Dual Tuners. Ideal for
multiroom systems, the MR85 is available with a
second tuner (the TM1 module) that operates
independently. A thoroughly engineered broad-
cast monitor, the MR85 reveals the upper limits
of AM and FM performance. The supplied RAA1
AM antenna can be positioned away from
sources of interference (e.g., TV sets, fluorescent
lights) for greatly improved AM quality.
MVS3 A/V Selector. The MVS3 connects to the
VIDEO data output of the MA6900 and accom-
modates five additional A/V sources.
RCT4 Remote Translator. The Translator allows
non-McIntosh components to be operated with a
McIntosh handheld remote or keypad controller. It
connects to the data outputs on the MA6900.
PC4 AC Power Controller. The PC4 provides
five AC outlets (four switched) for turning non-
McIntosh components on and off automatically
when it is connected to the power control output
of a Control Center or Integrated Amplifier.
HC1 Home Controller. The HC1 connects to the
HOME data output and allows operation of other
devices such as lights and movie screens via a
McIntosh handheld remote or keypad controller.
WK2 Keypad Controller or R649 IR Sensor.
With switching for two outputs, the MA6900 can
feed music to a second zone with the addition of
a power amp and operation via keypad or sen-
sor.
Academy Series Loudspeakers. The Academy
loudspeakers satisfy the often contradictory
demands of pure music versus movie sound. All
Academy loudspeakers use the acclaimed
LD/HP
®
driver – which significantly reduces bass
distortion while increasing power handling.
Academy models are available in floorstanding,
bookshelf, in-wall, and subwoofer models in a
variety of finishes.

Thermal Cutout. If the cooling air is blocked and the power transistors become too hot,
thermal cutouts protect against overheating until the amp cools.
DC Failure protection. In the rare event of an output circuit failure, any DC current that appears in
the output is shunted to ground by the autoformer, protecting the loudspeakers from damage.
Turn-On Delay. This circuit delays operation for about two seconds after turn-on in order to avoid
any pops or thumps generated as other equipment turns on.
Soft Start inrush protection. Thermistors in the power transformer primary circuit act as a cush-
ion against inrush current, eliminating component stress during turn-on. Soft Start is one of many
design details that contribute to the remarkable longevity of McIntosh equipment.
EXCLUSIVE MCINTOSH 5-BAND EQUALIZER. The equalizer provides 12dB of boost or cut at cen-
ter frequencies of 30, 150, 500, 1500, and 10000Hz. Notice that the center frequencies are clus-
tered at the lower end of the spectrum where room correction is most often needed. When an
equalizer control is in the center or flat position, its circuit components are completely removed
from the signal path.
CONTROL DATA OUTPUTS. To facilitate system integration, the MA6900 outputs control data for
source components. This allows remote operation of non-McIntosh components either by direct con-
nection to compatible data inputs or via a McIntosh Remote Translator.
REMOTE POWER CONTROL. This enables the MA6900 to turn other McIntosh components on/off.

Consumer electronics products usually are viewed as short-
term investments because they don’t last or they quickly
become obsolete in some way. But 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 customers are presented with McIntosh products, cri-
teria 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
then becomes clear: There is nothing like a McIntosh.
