CR16 Multizone A/V Control Center
MC58 Eight-Channel Power Amplifier
McIntosh Multizone A/V
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
smart investment, as it uses just one set of audio and video sources to supply any
number of rooms or areas in your home. The CR16 Multizone A/V Control Center and the
MC58 8-Channel Power Amplifier go together like hand in glove, offering abundant
possibilities for a house-wide entertainment system with true McIntosh performance.

Featured Technologies
FOUR INDEPENDENT ZONES (CR16). The CR16 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 CR16s
can be linked (“cascaded”) for a total of 24 independent A/V zones.
CONTROL DATA OUTPUTS (CR16). To facilitate system integration, the CR16 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 (CR16 + MC58). The MC58 receives power on/off data via
its single cable link to the CR16. In addition, power control jacks provide the same capability when the units are not linked. A special multipin jack on the CR16 connects to the PC3
AC Power Controller, which coordinates power on/off of zone amps, audio sources, and
video components.

home theater
All it takes is one cable to join the
CR16 and the MC58 (or MC7108)
… and one more to link a multizone system to a home theater.
EXCLUSIVE MCINTOSH TONE CONTROLS (CR16). Judicious use of well-designed bass
and treble controls can compensate for acoustical irregularities. Each zone of the CR16 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 (CR16). High-resolution video sources
such as DVDs demand high-quality video switching. Each CR16 video input is terminated
with 75 ohms to maintain a proper impedance match. Video buffer amplifiers feed the
CR16’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 CR16 or a master preamp.
BALANCED CONNECTIONS (CR16). Balanced connections guard against induced noise
and allow long cable runs without compromising sound quality. The CR16’s four balanced
outputs can be used to feed larger power amps (such as the MC202) for installations that
require high sound levels.
CONFIGURABLE POWER OUTPUT (MC58). Channels 1/2, 3/4, 5/6, and 7/8 can be
operated either in the normal mode (50W 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 50Wx2
for the surround speakers.
collection of technologies that enhance performance and reliability and protect the amp
and the loudspeakers.
Power Guard® clipping protection. Power Guard ensures that the amplifier will always
deliver full power without causing clipping distortion. If an amplifier channel is overdriven, Power Guard automatically reduces the input volume just enough to keep distortion
CR16/MC58 Companion Products
The McIntosh products shown at right are logical
companions for the CR16/MC58. Separate literature is available. Check with your McIntosh
dealer for late additions.
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 CR16 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.) In addition, an RS-232 port makes
the CR16 compatible with popular touchscreen
remotes from Crestron and Panja.
RCT4 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 CR16.
HC1 Home Controller. The HC1 connects to the
CR16’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 CR16.
PC4 AC Power Control. The PC4 provides five
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.
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 broadcast 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.
MX132 A/V Control Center + Processor. One
cable from the MX132 to the CR16 will integrate
a McIntosh home theater with a McIntosh multizone system. This lets the two systems share
one group of source components.
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. The
compact HT5 has a footprint less than 10 inches
square. The LS320 features arched bridge truss
construction that is virtually immune to vibrations
that distort sound. A special tweeter plate
reduces edge diffraction cancellation and is
mounted on traditional McIntosh screened black
glass. The WS320 is the wall-mount sibling of the
LS320 and comes in a paintable white finish. At
400 watts, the PS112 is McIntosh’s most powerful amplified subwoofer. It features arched bridge
truss construction and a screened black glass
control panel.

below 2% and prevent any clipping distortion. Thanks to an optical resistor, Power Guard acts literally at the speed of light, producing absolutely no audible side effects. An amplifier with Power
Guard will actually deliver clipping-free output well above its rated power.
Sentry Monitor® current protection. Sentry Monitor continually senses the voltage and current of the
output stage and confines it to a safe limit. Sentry Monitor does not limit 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.
Consumer electronics products usually are viewed as shortterm 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, 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
then becomes clear: There is nothing like a McIntosh.
