he awesome sonic potential of DVD movies with Dolby Digital ®and DTS ®prac-
tically begs for McIntosh-quality reproduction. And if youve been waiting for an
all-in-one home theater receiver that can hold its own against high-performance
separates-¦ the MHT100 is all that, and more. Featuring eight channels of ampli-
fication (two for Zone B) plus 24-bit DSP processing for Dolby Digital, DTS, Pro
Logic, and 6.1 Expanded Surround, the MHT100 combines the brains of the crit-
ically acclaimed MX132 controller/processor with the indomitable brawn of McIntosh power
amps. Although we prefer the term A/V System Controller, consider the MHT100 as The
McIntosh of Home Theater receivers.

24-BIT DSP PROCESSING.The MHT100 features one of the most powerful DSP engines avail-
able to decode Dolby Digital ®, Pro Logic, and DTS ®soundtracks.
20-BIT ANALOG-TO-DIGITAL CONVERSION. Analog inputs to Zone A feed a 20-bit A-to-D
converter featuring AILC (automatic input level control). The AILC acts similar to Power Guard
-“ if overdrive is detected a digitally controlled attenuator turns down the input signal.
20-BIT DIGITAL-TO-ANALOG CONVERSION. The output of the DSP module has four 20-bit
stereo D-to-A converters that feed the volume control stage.
SUPER-TRACKING VOLUME CONTROL. Level differences among channels in a stereo or sur-
round system compromise sound imaging. The MHT100 uses an eight-gang precision digital-
ly controlled volume attenuator with tracking accuracy better than 0.5dB for all channels.
BUFFERED FET AUDIO SWITCHING. All eight inputs of the MHT100 are buffered with high-
performance op-amps. These provide a uniform high input impedance, protect the FET switches
from static discharge damage, and supply the necessary isolation for multiple Zone switching.
MATCHED AND BUFFERED VIDEO SWITCHING. High-resolution video sources such as DVDs
demand high-quality video switching. All video switching in the MHT100 is done at 75 -„¦. FET
switches select the input in use. Then the signal is restored to its original value by a broadband
video buffer amplifier with 75 -„¦output impedance. There are buffers for both Zone A and Zone
B monitor outputs.
CONTROL LOGIC. All inputs, outputs, and data ports are controlled by logic circuits in the
MHT100, ensuring low-resistance, distortion-free switches that never need cleaning. Another
benefit is that non-selected inputs are truly off, eliminating potential sources of interference.
ON-SCREEN DISPLAY. Initial setup is a one-time set-and-forget procedure. In the setup mode,\
all speaker size selection, room calibration, and custom sound enhancement features can be
set from the listening position via remote control. During regular operation, an overlay style
on-screen display shows changes in input, volume, trim, and mode selections.
TRIM SELECT. Settings for subwoofer, surround speakers, center speaker, treble, bass, and dis-
play can be adjusted using TRIM UP/DOWN or via remote. The settings are shown on the
MHT100s fluorescent display and on-screen. For each operating mode only the appropriate
trim options can be accessed.
