Featured Technologies
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 overdriven,
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

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 non-McIntosh 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.)
