The SETTING DISTANCES screen displays when the MC-12 calibrates speaker distances.

During speaker distance calibration, the MC-12 sends calibration noise signals to the Main Zone audio output connectors in the order shown on the SETTING DISTANCES screen. The cursor auto- matically scrolls downward through speaker calibration parameters, highlighting each parameter while the MC-12 calculates a distance for the corresponding speaker. As it finishes each parameter, the MC-12 enters the calibrated value or an ERROR message to the right of the parameter label.

3 • Because of the way low frequency signals propagate in most listening spaces, automatic speaker dis- tance calibration often produces unreliable results for subwoofers and LFE subwoofers. For this reason the MC-12 does not send calibration noise signals to the Subwoofer L/R and LFE output connectors during speaker distance calibration. Instead, the MC-12 automatically calibrates subwoofer and LFE subwoofer distances to the shortest distance of the other speakers. These distances can be manually adjusted. See “PERFORMING MANUAL SPEAKER DISTANCE CALIBRATION” on page 3-53.

This step does not occur when the AUTO SPEAKER SETUP menu LEVELS option is selected.

The SETTING LEVELS screen displays when the MC-12 calibrates output levels.

The MC-12 sends calibration noise signals to the Main Zone audio output connectors in the order shown on the SETTING LEVELS screen. The cursor automatically scrolls downward through speaker calibration parameters, highlighting each parameter while the MC-12 calcu- lates an output level for the corresponding speaker. As it finishes each parameter, the MC-12 enters the calibrated value or an ERROR message to the right of the parameter label.

This feature is particularly appealing to users who prefer the warmth and richness of analog sound. The processor also boasts a 24-bit/192 kHz digital-to-analog converter (DAC), ensuring that audio playback is both high-fidelity and precise.

Equipped with a range of surround sound formats, including Dolby Digital, DTS, and THX, the MC-12 provides an immersive audio experience. It supports multiple channels, delivering up to 7.1 surround sound, making it ideal for cinema-style setups. The processor also features Lexicon's proprietary Logic 7 processing, which enhances stereo and discrete surround signals for a more enveloping soundstage.

The MC-12 features customizable room acoustic settings that allow users to tailor the audio output to their specific environment. An integrated automatic calibration system uses sophisticated algorithms to analyze room acoustics and adjust speaker settings accordingly. This optimization ensures that users achieve the best possible sound quality, regardless of their room’s dimensions or layout.

Connectivity is another strong point of the MC-12. It comes with multiple inputs, including HDMI, coaxial, optical, and balanced inputs, allowing users to connect a variety of audio and video sources. Additionally, the processor includes both analog and digital outputs, ensuring compatibility with a multitude of external devices.

The Lexicon MC-12 also features a user-friendly interface, allowing for easy navigation and control. Its ergonomic design includes a sleek front panel and a backlit remote control, enhancing the overall user experience.

In summary, the Lexicon MC-12 stands out as a premium choice for audiophiles seeking exceptional sound quality and advanced features.
