DCM 100

Digital Crossover/Monitor

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 100 is configurable for passive and bi-amp operation of three screen channels. The DCM 100 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.

The DCM 100/DCM 300 greatly simplifies system wiring and set-up, significantly reducing installation time and labor cost. Connections to DCA amplifiers for input and monitor signals are made through QSC DataPort VGA-styles cables. Set-up is accomplished by a front panel USB cable connection, suing menu-driven, DPM Manager software for configuration. The program includes a database of QSC Intrinsic Correction settings for QSC cinema speaker models.

In addition to audio monitoring of DCA Series* amplifier inputs and outputs, DCM 100/DCM 300 includes QSC's exclusive "load fault" detection. It monitors amplifiers outputs and indicates any opens an shorts in the loudspeaker, providing confirmation that all ampifier outputs are functioning properly.

*DataPort connections also works with QSC ISA Series amplifiers, but will not provide open/short detection or standby function with ISA Series.
