24-BIT SIGNAL PROCESSING. The MX134 features one of the most powerful DSP engines ever.
A Motorola 24-bit DSP handles Dolby® Digital/Pro Logic, DTS®, THX® processing, and bass management.
THX SURROUND EX AND DTS ES. The latest 7.1 multi-channel formats are supported to reproduce the
Back Surround channel information. This produces the most convincing soundstage ever.
PRO LOGIC II DECODING FOR MOVIES AND MUSIC. Dolby’s latest technology improves the surround
imaging by providing separate surround channel information, as opposed to the mono surround channel
used in standard Pro Logic. For music, Pro Logic II allows full range reproduction from the surround speakers with no added delay.
HOME THX® CINEMA. The latest Speaker Position Time Synchronization and Decorrelation enhancements for Dolby Digital, Pro Logic II, and DTS optimize sound in rooms lacking proper speaker locations.
24-BIT CONVERSION. A 24-bit stereo A/D converter on the analog input and four 24-bit stereo D/A converters at the DSP output provide a 96kHz throughput sampling frequency.
PURE STEREO MODE. In Stereo Mode, analog signals bypass all DSP processors for the purest audiophile
sound. Digital signals of any type are down-mixed to a stereo output.

TWO INDEPENDENT ZONES. By using the RECORD output and an additional power amp, a second zone
can be created with independent control of power, volume, and input selection via an IR sensor or keypad.
Zone B amp
Zone A (Theater)
OPTIONAL INTERNAL TUNER. The MX134 has provisions for adding the McIntosh TM1 AM/FM Tuner
Module. The module is a dealer-installed option.
AUTOMATIC INPUT LEVEL CONTROL. 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.
REMOTE SELECTION OF MODES AND TRIM SETTINGS. All surround modes and settings for speakers and
tone can be adjusted using the remote control from the listening position or by using the TRIM LEVEL knob
on the front panel.
ON-SCREEN SETUP. Speaker size selection, room calibration, sound enhancement features, and other system settings can be set from the listening position via remote control. Default settings are chosen to work
with McIntosh Home Theater speakers, allowing customers to get excellent performance right out of the box.
SYSTEM CALIBRATION. The MX134 has internal sequential channel switching and a special sound generator to aid in setting output levels for all speakers.
RE-ASSIGNABLE INPUT SELECTION. Any or all of the 11 A/V inputs can be re-assigned (e.g., change the
name TAPE2 to the name DVD2). Unused inputs can be turned off so that the Input knob skips over them.
All six digital inputs and component video inputs may also be assigned to any A/V source.
Zone B (Multiroom)
CONTROL DATA OUTPUTS. To facilitate system integration, the MX134 outputs control data for McIntosh
source components. This also allows remote operation of non-McIntosh components either by direct connection to compatible data inputs or via a McIntosh Remote Translator.
REMOTE POWER CONTROL. The MC206 receives power on/off data via its cable link to the MX134.
Power control jacks provide the same capability when the units are used independently.
RS232 PORT. In addition to connections for McIntosh keypads and other external IR sensors, the MX134
includes an RS232 port for use with popular touchscreen remote controls (e.g., Crestron® and AMX®).
SUPER-TRACKING VOLUME CONTROL. Level differences among channels in a stereo or surround system compromise sound imaging. The MX134 uses an electronic volume control with tracking accuracy better than 0.5dB for all eight channels.
All it takes is one cable to join the MX134 and the MC206 (or MC126)… and one more to link a home theater to a multizone system.
MX134/MC206 Companion Products
The McIntosh products shown at right are logical
companions for the MX134/MC206. Separate literature is available. Check with your McIntosh dealer for
late additions.
TM1 Optional Internal AM/FM Tuner. The dealerinstalled TM1 delivers the same exceptional performance as the stand-alone MR85 tuner.
MVP841 DVD/CD/Video CD Player. The MVP841
delivers crystal-clear DVD video and outputs 5.1 digital surround sound.
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 MX134.
PC4 AC Power Control. The PC4 provides six outlets (five switched) for turning non-McIntosh components on and off automatically when it is connected
to the power control output of the MX134.
HC1 Home Controller. The HC1 connects to the
MX134’s HOME data output and allows remote
operation of other home devices such as lights and
movie screens.
WK2, WK3, WK4 Keypad Controllers. These can
be used to operate Zones A and B of the MX134. In
addition, an RS-232 port makes the MX134 compatible with popular touchscreen remotes.
CR16 Multizone A/V Control Center. A single cable
connects the MX134 and the CR16, integrating a
McIntosh home theater and a multizone system. This
lets the two systems share one group of source
components, including the MX134’s optional TM1
AM/FM tuner.
Academy Series Loudspeakers. The Academy
speakers satisfy the often contradictory demands of
pure music versus movie sound. All McIntosh loudspeakers use the acclaimed LD/HP ® driver, which
significantly reduces bass distortion while increasing
power handling. The compact HT5 has a small footprint. The LS320 and CS350 feature arched bridge
truss construction that is virtually immune to vibrations that can distort sound. The tweeter plate in the
LS320 reduces edge diffraction cancellation. The
CS350 center channel speaker is sonically matched
to the LS320 and features five tweeters wired in a
Bessell Function Array that acts as a point source.
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 black glass control panel. (All Academy
speakers are fully described in a separate brochure.)
Featured Technologies (cont’d.)
ACTIVE VARIABLE LOUDNESS COMPENSATION. Typical loudness circuits apply a fixed amount of compensation for listening at low volume. The MX134 includes a separate variable loudness control that
applies compensation proportionately. When off, the loudness circuit elements are completely removed
from the signal path.
COMPONENT VIDEO SWITCHING AND UP-CONVERSION. High-resolution DVDs demand high-quality
video switching. The MX134 handles composite, “S”, and component video signals. New Digital Video
Processing Circuitry will up-convert composite video to “S” video (Zones A and B) and composite and “S”
video to component video (Zone A only). Video buffer amps feed the two monitor video outputs, ensuring
no loss in picture quality.
EXCLUSIVE MCINTOSH POWER ASSURANCE SYSTEM. Power Assurance is a collection of technologies
that enhance performance and reliability and protect the MC206 and the loudspeakers.
Power Guard® clipping protection. Power Guard ensures that the amplifier will always deliver full power
without audible clipping distortion. If an amplifier channel is overdriven, Power Guard automatically
reduces the input volume just enough to keep distortion below 2%. Thanks to an optical resistor, Power
Guard acts quickly, producing absolutely no audible side effects. An amplifier with Power Guard will actually deliver clipping-free output well above its rated power.

The patented McIntosh Power Guard in the
MC206 provides real-time clipping protection
without affecting power output or sound quality.
a. test signal b. overdriven amp without Power
Guard produces SEVERE clipping c. overdriven
amp with Power Guard produces minimal distortion.
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 Protection. If the cooling air is blocked and the power transistors become too hot,
thermal cutouts protect against overheating.
Turn-On Transient Protection. 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 input circuit primary 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.
ILLUMINATED PEAK-RESPONDING METERS. McIntosh meters respond 95% full scale to a single-cycle
tone burst at 2kHz. Response is more than 10 times faster than a professional VU meter. In the MC206, a
four-position switch selects the channels to be monitored by the three meters. When the MC206 and
MX134 are linked via the single cable connection, the correct meter mode is selected automatically when the
system is calibrated. The meter illumination can also be switched off.
