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.
Power Guard
®
clipping protection.
Power Guard ensures that the amplifier will always
deliver full power without causing clipping distortion. If an amplifier channel is over-
driven, Power Guard automatically reduces the input volume just enough to keep distortion
below 2% and prevent any clipping distortion. Thanks to an optical resistor, Power Guard
All it takes is one cable to join
the CR12 and the MC7108…
and one more to link a multi-
zone system to a home theater.
