ABOUT THE MC-8
Thank you for purchasing the MC-8 Digital Controller, an 8-channel
audio and video control center with independent zone monitoring
that provides control of audio and video source selection in two
zones at the same time. The MC-8 includes eight configurable
inputs, each of which can be assigned to its eight digital audio,
eight analog audio, five composite video, five S-video, or three
component video input connectors. The analog connectors can be
configured for up to two 5.1-channel sources. In addition, the
MC-8 balanced offers balanced analog audio output connectors for
all Main Zone and Zone 2 channels.
Inside and out, the MC-8 is designed for possible future
developments. The rear panel houses one RS-232 connector
capable of performing configuration downloads and flash memory
software upgrades and another capable of supporting future
developments. The rear panel also includes two removable access
panels to accommodate connectors for emerging technologies.
More than just an audio and video control center, the MC-8 offers
the latest version of Lexicon's critically acclaimed LOGIC7®
decoding, which creates a 7.1-channel output signal from stereo,
5.1-, and 6.1-channel sources. Unlike other decoders, LOGIC7
decoding is compatible with all input sources and requires no special
encoding. Because the improvement it provides is clearly audible,
LOGIC7 is widely regarded as the finest available.
In addition to LOGIC7, the MC-8 offers Dolby Digital Surround EX,
Dolby Pro Logic II, Dolby Pro Logic, dts 96/24, dts NEO:6, dts-ES,
THX Ultra2, and THX Surround EX decoding. THX Ultra2 Certification
guarantees that the MC-8 meets the highest THX specifications.

With four floating-point SHARC™ digital signal processing (DSP)
engines, the MC-8 boasts enormous processing power. These
powerful processors perform custom Lexicon processing such as
LOGIC7 decoding, bass enhancement, dialog enhancement, auto
azimuth, 5-speaker enhancement, bass management, high-precision
digital crossovers, and audio controls. These features are available at
sample rates up to 96kHz, with 24-bit resolution to retain top
performance from all sources. In addition, a fifth DSP engine is
dedicated to decoding multi-channel compressed audio sources.
The MC-8 is one of the most advanced audio and video control
centers available. High-precision 24-bit/96kHz A/D converters can
be used to convert stereo analog audio input signals to digital
signals, allowing the MC-8 to provide the benefits of precise digital
signal processing without sacrificing signal integrity. Alternatively,
stereo analog signals can bypass A/D conversion and internal
processing, following a pure signal path directly to the output
connectors.
Digital audio input signals are processed through a two-stage phase
lock loop for extremely low intrinsic jitter and high rejection.
Lexicon's proprietary auto azimuth technology corrects timing and
level imbalances in stereo sources, ensuring exceptionally accurate
playback of surround-encoded sources. A digital audio pass-through
output is available for recording digital signals with a CD recorder
or a similar component.
