Based on the reference MC-12, the MC-4 Digital Controller is
perfectly suited for less complex multi-channel systems in
which sound quality, picture quality, ease-of-use and reliabil­ity are still of paramount importance.

Value

Equipped with 8 configurable inputs, and 8 channels of out­put, the MC-4 is ideal for all but the most elaborate systems.
Drawing on Lexicon's legendary expertise in digital audio,
the MC-4 offers superior performance and value for today's
music and home theater enthusiast.

Powerful

At the heart of the MC-4 are four Analog Devices SHARC dig­ital signal processing engines, one Cirrus Logic DSP engine,
and eight 24-bit/192kHz digital-to-analog converters - an

architecture that is nearly identical to the MC-12. As a result,
the MC-12 and MC-4 share the same tremendous processing
power and sonic soul. The MC-4 includes THX Ultra2 certifi­cation and dts 96/24 decoding. Rounding out its impressive
list of playback technologies: Dolby Digital EX, Pro-Logic II,
dts-ES, dts Neo6, and LOGIC7.

LOGIC7

The MC-4 features Lexicon's decoding technology: LOGIC7.
Based on years of psychoacoustic research, LOGIC7 strikes a
delicate balance between channel separation and surround
envelopment. For music, film, and broadcast sources, LOGIC7
distinguishes between primary and background signals and
processes them appropriately. Prominent sounds like a
singer's voice or an airplane's roar are reproduced with stun­ning clarity. The signal is sent to the appropriate speaker with

• 8 channels, 8 configurable inputs

• Up to two 5.1-channel analog audio inputs

• Analog bypass available for stereo and 5.1-channel analog audio
inputs

• S/PDIF coaxial and S/PDIF optical digital audio inputs

• Automatic switching between analog and digital audio inputs

• 24-bit/192kHz D/A converters

• Stereo side and rear outputs and a dedicated subwoofer output

• 2 broadcast-quality video switchers

• 3 component video inputs with full HD-TV compatibility

• 5 S-video and 5 composite video inputs

• 4 32-bit, floating-point DSP engines

• Separate DSP engine to decode Dolby Digital and DTS signals

high channel separation, while secondary sounds like the
ambient noise of a concert hall or the great outdoors are
reproduced with amazing spaciousness. With LOGIC7, the
listener experiences an unmatched sense of involvement.

Connected

With formats such as DVD-Video, DVD-Audio, Super Audio
CD, and High-Definition TV, the demand for input connectors
has grown. The MC-4 provides compatibility with these for­mats, offering 3 component video inputs and 8 configurable
analog inputs. The analog inputs can be configured as 8
stereo inputs, 5 stereo inputs plus one 5.1-channel
input, or 2 stereo inputs plus two 5.1-channel
inputs for separate DVD-A and SACD
sources.

Simple

The MC-4 uses the same intuitive on-screen
menu system and user interface as the MC-12 for
navigation of the set-up options and features. Both
new users and those that are familiar with Lexicon digi­tal controllers will instantly feel at home with the MC-4 and
will be fine-tuning it in minutes.

Conclusion

Designed with a careful balance of performance and function,
the MC-4 is sure to impress with its stellar performance, sim­ple user interface, and set-up flexibility. Combined with an RT­10 disc player and an LX series power amplifier, the MC-4
serves as the core of a high performance, high value home
theater system.
