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

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.
