Lexicon MC-14 Surround Sound Processor

Raising the Standard for Ultrahigh-end Luxury Audio

The Lexison MC-14 Analog / Digital Controller, is a reference-quality, 8-channel audio and video control center with independent zone monitoring to provide control of input source selection in two zones at the same time. The analog input allows for a true analog bypass mode to create a very high quality analog stereo preamp for critical listening.

The MC-14 features an HDMI interface that enables the transmission of uncompressed digital audio and video signals through a single connector. The MC-14 can pass digital video signals of up to 1080p, 12 bit and 3D, and multiple digital audio channels (7.1 channels) at sample rates of up to 192 kHz through the HDMI interface. The MC-14 also supports the High-bandwidth Digital Content Protection (HDCP) technology that comprises data encryption and authentication of the partner equipment.

Beyond the HDMI connectors and standard 7.1-channel audio output connectors, the rear panel includes stereo rear and stereo subwoofer connectors to provide even more audio channels. All Main Zone audio output connectors include 24-bit/192kHz D/A converters operating in dual differential mode. In addition, the MC-14 includes balanced and unbalanced audio output connectors for all Main Zone channels.

Two connectors are provided for external control. One RS232 9-pin serial and one Ethernet 10BaseT which also acts as a web page server, User Interface and firmware update tool.

The MC-14 is also equipped with Dolby® Digital Surround EX™, Dolby Pro Logic®, Dolby Pro Logic II, Dolby Pro Logic IIx, DTS 96/24™, DTS NEO:6®, DTS-ES®, Dolby True HD, Digital Plus, Digital EX, Pro Logic IIx, DTS-HD master audio, and Dolby volume

With two 32-bit floating-point TI DA710 digital signal processing (DSP) engines, the MC-14 offers unparalleled processing power. This processing is available at digital input sample rates up to 192 kHz, with 24-bit resolution to retain top performance from all input sources and listening modes.

High-precision 192kHz/24-bit A/D converters can be used to convert stereo analog audio input signals to digital signals, allowing the MC-14 to provide the benefits of precise digital signal processing without sacrificing signal integrity. Additionally, all output D/A convertors can operate at up to 192 kHz/24-bit and are completely asynchronous from input convertors and all digital inputs, allowing the outputs to be completely buffered and internally clocked to a very stable crystal oscillator. This is especially important in removing jitter from the unstable sources, especially HDMI. This allows the MC-14 to give the best possible signal output and maintain the highest possible resolution even on less than ideal sources.

To complement its audio performance, the MC-14 features a broadcast-quality HDMI video switcher that does not process or manipulate the signal in any way. This allows full resolution HDMI video to pass through the unit without any additional processing. This also allows for very high data and video resolution throughput including 3D.
