24-BIT DSP PROCESSING. The MHT100 features one of the most powerful DSP engines available

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 surround

system compromise sound imaging. The MHT100 uses an eight-gang precision digitally

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 75Ω. FET

switches select the input in use. Then the signal is restored to its original value by a broadband

video buffer amplifier with 75Ω 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 display

can be adjusted using TRIM UP/DOWN or via remote. The settings are shown on the

MHT100’s fluorescent display and on-screen. For each operating mode only the appropriate

trim options can be accessed.
