DPM 100/100H

Digital Processor/Monitor/Crossover

DPM Series processors are a powerful solution for today’s D-Cinema audio systems.


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 is configurable for passive and bi-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 100H)
  • Dolby® Digital Plus® and DTS®-HD
  • Network control and monitoring via SNMP
  • 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 or bi-amp screen channels
  • Compatible with all existing DCA amplifiers — thousands of DCA-equipped screens are ready for full network monitoring and control
  • Multiple Bypass modes 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

The DPM 100 digital signal processing capability outperforms traditional analog crossovers and equalizers for optimized speaker performance. Crossover frequency, 1/3 octave graphic EQ, parametric equalization, polarity, delay and gain can be precisely adjusted for each speaker in your system. Passive or active 2-way crossovers are available for three screen channels. QSC’s proprietary Intrinsic Correction adjusts for the intrinsic behaviors of loudspeakers, removing any anomalies from the equation of 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.

The DPM 100 greatly simplifies system wiring and set-up, significantly reducing installation time and labor cost. Digital input to the DPM 100 is provided via RJ45 cables from the D-Cinema server or IMB. Connections to DCA amplifiers for input and monitor signals are made through QSC DataPort VGA-style cables. Set-up is accomplished by a front panel USB cable connection, using a menu-driven, PC-based software program for configuration. The program includes a speaker data file that lists default parameters for popular QSC cinema speaker models.

In addition to audio monitoring of amplifier inputs and outputs, DPM 100 includes QSC’s exclusive “load fault” detection. It monitors all amplifier outputs and indicates any opens and shorts in the loudspeakers, providing confirmation that all amplifier outputs are functioning properly. In addition, the DPM 100 detects all amplifier clipping, protect modes and heat sink temperature for reporting via SNMP or Ethernet.
