Overview
The DPM builds on the legacy of QSC’s DCM and DCP products to provide all signal processing 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 DPM optimizes loudspeaker performance while simplifying cinema sound system wiring and configuration. The DPM 300 is configurable for passive, bi-amp, tri-amp and quad-amp operation and 2 or 4 surround channels (5.1 or 7.1).
Features
- Ten digital inputs for 5.1 and 7.1 soundtracks and HI/VI
- HDMI input/output for non-sync sources (DPM 300H)
- Dolby Digital Plus™ and DTS-HD® (DPM 300H)
- Control and monitoring via Ethernet including full SNMP support
- Serial automation control via RS-232
- Analog Inputs for film processors, non-sync and Mic/Line
- Master volume and full 1/3 Octave Graphic EQ on all channels (except subwoofer)
- Booth Monitor loudspeaker and headphone jack
- Digital Loudspeaker Crossovers — three passive bi-, tri-, or quad-amp screen channels
- Compatible with all existing DCA amplifiers — thousands of DCA-equipped screens are ready for full network monitoring and control
- Bypass mode routes audio around failed components to insure that the show will go on
- Intrinsic Correction™ for DCS loudspeakers for optimal “out of box” performance and reduced set-up time
- Continued development of software and firmware will add new capabilities to the existing hardware with easy firmware updates
