Most impressive about the MC-12 HD is its extensive custom processing capabilities. Four 32-bit floating-point DSP engines provide vast resources for such proprietary features as Logic 7, Auto Azimuth correction, five-speaker enhancement, bass enhancement, and dialog enhancement. Lexicon?s bass management system, digital crossovers and tone controls are also powered by these DSP engines. This processing is performed at sample rates up to 96kHz with 24-bit resolution to retain top performance from all input sources. A fifth DSP engine is dedicated to decoding Dolby Digital and DTS sources. Inside and out, the MC-12 HD is designed to accommodate potential hardware and software advancements with internal expansion, a removable rear panel access plate, and two RS-232 connectors.
