MC-12HD Getting Started
1-3
These DSP engines perform custom Lexicon processing such as
Logic 7 decoding, bass enhancement, dialog enhancement, auto
azimuth, 5-speaker enhancement, bass management, high-
precision digital crossovers, and tone controls. This processing is
available at sample rates up to 96kHz, with 24-bit resolution to
retain top performance from all input sources and listening modes.
A fifth DSP engine is dedicated to decoding multi-channel
compressed audio sources.
High-precision 24-bit/96kHz A/D converters can be used to convert
stereo and 5.1 analog audio input signals to digital signals,
allowing the MC-12HD to provide the benefits of precise digital
signal processing without sacrificing signal integrity. Alternatively,
stereo and 5.1 analog signals can bypass A/D conversion and
internal processing to remain in the analog domain straight to the
output connectors.
Digital audio input signals are processed through a two-stage
phase lock loop for extremely low intrinsic jitter and high jitter
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 option is available for recording digital
signals with a CD recorder or a similar component.
To complement its audio performance, the MC-12HD features two
broadcast-quality video switchers. An ultra-wide bandwidth
component video switcher accepts analog component or RGB video
signals, and can pass analog high-definition (HD),
enhanced-definition (ED), and standard-definition (SD) TV signals. A
composite and S-video switcher accepts NTSC, PAL or SECAM video
signals. Both switchers are designed to pass video signals without
alteration or degradation. In addition, the MC-12HD can convert
composite and S-video input signals to analog component video.
High-definition digital TV (HDTV) broadcasts require equipment
that can process and display digital video signals at a resolution of
either 720p or 1080i. For sources with HDMI digital video outputs,
the MC-12HD delivers these resolutions through the HDMI output
to compatible display devices.
Analog 720p or 1080i video signals can pass through the
broadcast-quality component video switcher. In comparison, most
standard-definition (SDTV) broadcasts have a resolution of 480i.
Some DVD players and enhanced-definition (ED) digital TV
broadcasts have a 480p resolution. For analog video input sources,
the MC-12HD delivers these resolutions through the component
video switcher. For digital video input sources using an HDMI
interface, the MC-12HD delivers these resolutions through the
HDMI switcher.
Resolution is defined by the number of horizontal lines displayed
on-screen that comprise each frame of a video image. The more
lines of resolution used to create each frame of video, the greater
the detail and sharpness of the image. For example, the resolution
known as 720p refers to 720 horizontal lines of progressive video.
The resolution known as 1080i refers to 1,080 lines of interlaced
video.
An unparalleled processor, the MC-12HD conveys the best in music
and cinema with awesome power and leading-edge technological
sophistication. Even the most demanding enthusiasts will be
impressed with its exceptional performance. The MC-12HD is a
must-have addition for any high-quality home theater
