Q-SYS DCM-300 8-Channel Digital Cinema Audio Processor

The DCM Series crossover/monitors are a powerful solution for today's D-Cinema audio systems for installations that use a separate cinema processor such as QSC USL JSD Series processors. The new DCM builds on the legacy of QSC's DCP and DPM products to provide loudspeaker crossover and monitoring functions for Digital Cinema in a Single integrated system. Designed to be used with QSC's Digital Cinema Amplifiers (DCA) and featuring advanced Intrinsic Correction™ settings for QSC's Digital Cinema Speakers (DCS), the DCM optimizes loudspeaker performance while simplifying cinema sound system wiring and configuration. The DCM 300 is configurable for tri- or quad- amp operation for three screen channels. The DCM 300 accommodates 2 or 4 surround channels (5.1 or 7.1)

When used with QSC DCS Series cinema loudspeakers, QSC's proprietary Intrinsic Correction adjusts for the intrinsic behaviours of loudspeakers, removing any anomalies from the equation factors that affect measured response and, ultimately, the quality of sound. The result is optimal "out of the box" performance while minimizing on-site room tuning.

Features:

• Analog inputs accept audio from cinema processors or other 8 channel analog audio sources
• QSC Intrinsic Correction DSP Settings for optimal performance of QSC cinema speakers
• Booth monitor with front panel control for easy operation
• Passive, bi-, tri- or quad-amp
• Compatible with all existing QSC DCA amplifiers
• Bypass mode - routes audio around failed components to ensure that the show will go on
• Control and monitoring via Ethernet including full SNMP support
• Continued development of software and firmware will add new capabilities via easy updates
