practically begs for McIntosh-quality reproduction. The MX132 and MC7205 are the foundation for a powerful and engaging home theater experience. The MX132 features the absolute finest digital processing engine available for surround sound. As the “brains” of a home theater system, its roster of capabilities may astonish even the most jaded scorekeepers. The MX132 is logically organized, handles audio and video signals in purist fashion, and integrates elegantly with other McIntosh systems and components.

MC7205
5-Channel Power Amplifier
All it takes is one cable to join the MX132 and the MC7205… and one more to link a home theater to a multizone system.
Featured Technologies
24-BIT SIGNAL PROCESSING (MX132). The MX132 features one of the most powerful
DSP engines available. Three Motorola 24-bit digital signal processors decode Dolby
Digital ® , Pro Logic, and DTS ® soundtracks. One divides a digital bit stream into the
Dolby Digital and Pro Logic channels. Another is dedicated to decoding DTS. The third handles bass-channel management as well as ancillary functions. Except in pure Stereo mode, all analog inputs are processed by a 24-bit stereo A/D converter. Three additional
24-bit D/A converters handle the DSP output.
HOME THX ® CINEMA (MX132). Speaker Position Time Synchronization and Dynamic
Decorrelation – two THX enhancements for Dolby Digital – optimize sound in rooms lacking proper speaker locations.
TRIM SELECT (MX132). Settings for subwoofer, surround speakers, center speaker, treble, bass, loudness, and display can be adjusted using the TRIM LEVEL knob or via remote.
The settings are shown on the MX132’s large display. For each operating mode only the appropriate trim options can be accessed.
ON-SCREEN SETUP (MX132). All speaker size selection, room calibration, and custom sound enhancement features can be set from the listening position via remote control.
CONTROL DATA OUTPUTS (MX132). To facilitate system integration, the MX132 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 (MX132 + MC7205). The MC7205 receives power on/off data via its cable link to the MX132. In addition, power control jacks provide the same capability when the units are used independently. A special multipin jack on the MX132 connects to the PC3 AC Power Controller (see “Companions” section).
SUPER-TRACKING VOLUME CONTROL (MX132). Level differences among channels in a stereo or surround system compromise sound imaging. The MX132 uses an electronic volume control with tracking accuracy better than 0.5dB for all six channels.
ACTIVE VARIABLE LOUDNESS COMPENSATION (MX132). Typical loudness circuits apply a fixed amount of compensation for listening at low volume. The MX132 includes a separate loudness circuit that applies compensation proportionately. When off, the loudness circuit elements are completely removed from the signal path.
MATCHED AND BUFFERED VIDEO SWITCHING (MX132). High-resolution video sources such as DVDs demand high-quality video switching. Each MX132 video input is terminated with 75 ohms to maintain a proper impedance match. Video buffer amps feed the two monitor video outputs, ensuring no loss in picture quality. Built-in digital comb filters convert composite video to S-video, allowing use of S-video outputs for all video sources.
AUTOMATIC INPUT LEVEL CONTROL (MX132). The analog input to the DSP features a circuit similar to the Power Guard ® used in McIntosh amplifiers. AILC continuously monitors input voltage and if overdrive occurs reduces the input level, preventing distortion.
BALANCED CONNECTIONS (MX132 Zone B). A balanced connection provides 40dB more noise protection than an unbalanced connection. The balanced output of the
MX132’s Zone B allows distant placement of a Zone B amp without compromising sound.
About the MX132/MC7205 Companion Products
The McIntosh products shown at right are logical companions for the MX132/MC7205. Separate literature is available. Check with your McIntosh dealer for any late additions. McIntosh speaker systems are also covered in detail in separate literature.
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 MX132.
RFD2 AC-3 RF Demodulator. The RFD2 is required when connecting a laser disc player with a
Dolby Digital RF output to the MX132.
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 MX132 or the CR12.
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 MX132’s HOME data port and allows remote operation of other home devices such as lights and movie screens.
MC162 Power Amplifier. The MC162 is a good choice as a Zone B amplifier because it can form a balanced connection with the MX132, permitting a long cable run without degrading the sound.
In bridged mode an MC162 will deliver 500 watts to the HT2 subwoofer (see below), resulting in deep, well-controlled bass that will satisfy even large home theaters.
WK3 and WK4 Keypad Controllers. These can be used to operate Zones A and B of the MX132.
CR12 Multizone A/V Control Center. A single cable connects the MX132 and the CR12, allowing integration of a McIntosh home theater and multizone system. This lets the two systems share one group of source components, including the MX132’s built-in AM/FM tuner.
HT Series Loudspeakers. These THX ® -certified speakers deliver a musical, non-fatiguing sound not often heard from home theater speakers. The HT1 can be used for all three front channels or with the compact HT4 in the center. The rear-channel HT3F dipoles mount flush to a wall or ceiling and are also available in an on-wall version (HT3W). The HT2 passive subwoofer uses two
12-inch LD/HP ® drivers and can be driven by the potent MC162 in bridged mode.

Featured Technologies

EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM (MC7205). Power Assurance is a collection of technologies that enhance performance and reliability and protect the amp and speakers.
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 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.
ILLUMINATED PEAK-RESPONDING METERS (MC7205). McIntosh meters respond 95% full scale to a single-cycle tone burst at 2kHz. Response is almost 10-times faster than a professional VU meter. In the MC7205, a four-position switch selects the channels to be monitored by the three meters. When the MC7205 and MX132 are linked via the single cable connection, the correct meter mode is selected automatically. The meter illumination can also be switched off.
