Based on the award-winning MC-12, the Lexicon MC12HD EQ with balanced outputs and Room Equalisation, bring HDMI switching to the world’s most celebrated pre-amp/processor with an impressive six HDMI inputs and one HDMI output. In response to the growing availability of HDMI equipped source components, the MC12HD EQ balanced version will provide state-of-the-art sound quality and control for the most complex home entertainment systems. It retains the features of the acclaimed Lexicon MC-12 with the addition of HDMI switching capabilities and EQ room technologyWith the MC12HD EQ balanced version Lexicon takes an approach to solving the problems of room equalization that delivers better results than traditional methods, which simply attempt to flatten the frequency response of the listening room.

Lexicon’s V5 EQ algorithm measures the decay times of the room resonance modes and prioritises those with long decay times as being the most important to correct. This approach has far more impact on the audio experience than merely flattening the frequency response. Another benefit of using this method is that the long decay times occur throughout the room; correcting them for one listening position also fixes them for others, resulting in a more uniform experience from seat to seat. Unlike other EQ solutions, V5 EQ utilizes four microphones, allowing detection of room modes that would be missed by systems that employ only a single microphone. Using four microphones also provides improved accuracy resulting from correlated measurements. Lexicon Microphone Kit purchased separately.

Version 5.0 continues Lexicon’s improvement programme: a newly designed implementation of Logic7 extends the MC12HD EQ balanced version advantage over the competition; a fully automated level and time alignment system optimises the MC12HD EQ balanced version irrespective of room shape or speaker layout; the MC-12 HD’s Lexicon LIVE! system is able to create an expansive soundstage for live recordings. Automatic calibration of speaker distances and output levels is available using the rear panel microphone inputs and an optional Lexicon Microphone Kit.

With myriad features available in the Lexicon MC12HD EQ balanced version, the simple and intuitive user interface provides ultimate adjustability without being confusing. Access to the listening modes, input and output settings, speaker distances and levels is never more than a few button pushes away. The Lexicon MC12HD EQ balanced version’s three zones are independent, allowing for seamless control of multi-room systems. Because each zone is capable of routing a different input source, it is possible to watch a DVD in the home theatre while listening to a CD in the kitchen and recording a program from a satellite receiver to a DVD-R. The record zone can also be used to provide audio to a third room.

A glance at the Lexicon MC12HD EQ balanced version’s rear panel will show the tremendous array of inputs and outputs. Analogue audio is available on stereo connectors and a 5.1-channel connector, ideal for DVD-A or SACD sources such as the RT-20 Disc Player. High resolution 24-bit/96kHz analogue-to-digital converters can be used to bring these sources into the digital domain for processing or, for audio purists, a true analogue bypass option is available which keeps the signal in the analogue domain from input to output.

Digital audio input is available on one AES/EBU, six S/PDIF coaxial, and six S/PDIF optical connectors. These signals are processed at their native sampling rates through a two stage phase lock loop, achieving remarkably low intrinsic jitter and high jitter rejection. Lexicon’s proprietary auto azimuth processing corrects timing and level imbalances in stereo signals, resulting in exceptional channel separation in matrix-encoded sources.

The Lexicon MC12HD EQ balanced version has twelve channels of audio output, including stereo subwoofers, an LFE, and two auxiliary outputs. The MC-12HD balanced version adds XLR connectors for all Main Zone and Zone 2 audio outputs – useful for installations where long cable runs are required or where there is a high risk of RF interference.

Each of the outputs uses two 24-bit/192kHz DACs operating in dual-mono mode. This design extends the signal-to-noise ratio and dynamic range, resulting in superior sound quality. High precision crossovers and tone controls are digital to avoid the signal distortion their analogue counterparts often introduce. In addition, digitally controlled analogue output levels can be adjusted in 0.5dB increments.

For maximum flexibility, each of the main audio outputs has independent crossover, speaker distance, and output level control. The crossovers are available in 10Hz increments from 30 to 120Hz. If the THX speaker setup is selected, a THX 80Hz crossover setting is automatically applied to all main audio outputs. The MC-12 also provides access to advanced speaker array processing and, if a THX Ultra2-certified subwoofer is present, boundary gain compensation controls.
