or more than a decade McIntosh has offered multizone systems distinguished not
only by musical excellence but also by operating ease and adaptability. A
McIntosh multizone A/V system integrates seamlessly with non-McIntosh products
and can be scaled for any size installation. If you love music and you want
McIntosh performance, a multizone system gives you more of both. But it’s also a

FOUR INDEPENDENT ZONES (CR12). The CR12 is four audio/video preamps in one
chassis, each with its own input selector, volume control, and tone controls. For example,
you can listen to FM stereo in one zone, CD in a second, watch satellite in a third, and
watch a DVD movie in a fourth – all at the same time. In addition, a local “private” A/V
source can be connected for each zone for use only by that zone. As many as six CR12s
can be linked (“cascaded”) for a total of 24 independent A/V zones.
CONTROL DATA OUTPUTS (CR12). To facilitate system integration, the CR12 outputs
control data for source components. This allows remote operation of non-McIntosh components
either by direct connection to compatible data inputs or via a McIntosh Remote Translator.
REMOTE POWER CONTROL (CR12 + MC7108). The MC7108 receives power on/off
data via its single cable link to the CR12. In addition, power control jacks provide the
same capability when the units are not linked. A special multipin jack on the CR12 connects
to the PC3 AC Power Controller, which coordinates power on/off of zone amps, audio
sources, and video components.
EXCLUSIVE MCINTOSH TONE CONTROLS (CR12). Judicious use of well-designed bass
and treble controls can compensate for acoustical irregularities. Each zone of the CR12 has
its own bass and treble control that offers ±12dB adjustments with fine resolution, yet in
the “flat” position is completely removed from the signal path.
MATCHED AND BUFFERED VIDEO SWITCHING (CR12). High-resolution video sources
such as DVDs demand high-quality video switching. Each CR12 video input is terminated
with 75 ohms to maintain a proper impedance match. Video buffer amplifiers feed the
CR12’s monitor video output, ensuring no loss in picture quality. In addition, the input
buffers feed a line-matched signal to the individual video outputs, preventing signal
degradation if those sources are in turn fed to another CR12 or a master preamp.
BALANCED CONNECTIONS (CR12). Balanced connections guard against induced noise
and allow long cable runs without compromising sound quality. The CR12’s four balanced
outputs can be used to feed larger power amps (such as the MC162) for installations that
require high sound levels.
CONFIGURABLE POWER OUTPUT (MC7108). Channels 1/2, 3/4, 5/6, and 7/8 can be
operated either in the normal mode (40W x 8) or with each channel pair independently
bridged (100W x 4). Configurations of 7, 6, 5, and 4 channels are also possible. For example,
a 5-channel configuration for home theater would comprise three bridged channel pairs
plus two normal channels, resulting in 100Wx3 for left/center/right speakers and 40Wx2
for the surround speakers.
EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM (MC7108). Power Assurance is
a collection of technologies that enhance performance and reliability and protect the amp
and the loudspeakers.
All it takes is one cable to join
the CR12 and the MC7108…
and one more to link a multizone system to a home theater.

About the CR12/MC7108 Companion Products
The McIntosh products shown at right are logical companions for the CR12/MC7108. Separate
literature is available. Check with your McIntosh dealer for any late additions. McIntosh speaker
systems are also covered in detail in separate literature.
WK2, WK3, WK4 Keypad Controllers and R649 IR Sensor. The wall-mount, illuminated keypads
enable pushbutton operation and include IR sensors that relay commands from handheld
remotes. The CR12 can accommodate as many as four keypads or IR sensors in each of its four
zones. (See the separate McIntosh System Accessories literature for more on keypads and IR sensors.)
RCT3 Remote Translator. The Translator allows non-McIntosh components to be operated with
a McIntosh IR remote or keypad controller. It connects to the data outputs on the CR12.
HC1 Home Controller. The HC1 connects to the CR12’s HOME data output and allows remote
operation of other home devices such as lights and movie screens.
PC3 AC Power Controller. The PC3 provides a total of 14 AC outlets (11 switched, 3 unswitched)
for automatic AC control of zone amps, audio sources, and video components. It connects to a
multipin jack on the CR12.
PC4 AC Power Control. The PC4 provides five AC outlets (four switched) for turning nonMcIntosh components on and off automatically when it is connected to the power control output
of a Control Center or Integrated Amplifier.
MR7084 AM/FM Tuner with RAA1 Remote AM Antenna. Likely to be the most-used source in
a multizone system, the MR7084 tuner is a thoroughly engineered broadcast monitor that reveals
the upper limits of AM and FM performance. The optional RAA1 antenna can be positioned away
from sources of interference (e.g., TV sets, fluorescent lights) for greatly improved AM quality.
MX132 A/V Control Center + Processor. A single cable connection between the MX132 and
the CR12 integrates a McIntosh home theater and multizone system. This lets the two systems
share one group of source components. (The MX132 has a built-in AM/FM tuner and is supplied
with the RAA1 antenna, obviating the need for the MR7084.)

power output.
Thermal Cutout. If the cooling air is blocked and the power transistors become too hot,
thermal cutouts protect against overheating until the amp cools.
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 act as a cushion
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.

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.
