DCM-1 | DCM-3
QSC’s Digital Cinema Monitors provide signal
processing and monitor functions in a single
integrated system. Designed to be used with QSC’s
Digital Cinema Amplifiers (DCAs), DCMs optimize
loudspeaker performance while simplifying cinema
sound system wiring and configuration. The
DCM-1 and DCM-3 cover cinema systems ranging from
three to five screen channels, and is configurable for
bi-amp or tri-amp operation. DCMs are also compatible
with all cinema processor formats including Dolby
Digital Surround-EX and DTS-ES.
Digital Signal Processing
The DCM’s digital signal processing capability
outperforms traditional analog crossovers for optimized
speaker performance. Crossover frequency, parametric
equalization, polarity and gain can be precisely adjusted
for each speaker in your system. Digital delays, adjustable
in 20
µs increments, assure proper acoustical time-
alignment of loudspeaker drivers for smooth frequency
response, especially critical in three-way systems. A
passive emergency bypass crossover is also included
for fail-safe operation.
Less wiring, faster setup
DCMs greatly simplify system wiring and set-up,
significantly reducing installation time and labor cost.
Input to the DCM is provided via a standard DB-25
cable from the cinema processor. Connections to DCA
amplifiers for input and monitor signals are made through
a single QSC DataPort / VGA-style cable. All traditional
XLR and barrier strip terminations are eliminated.
DCMs also simplify set-up by using a menu-driven, PC-
based software program for configuration. The program
includes a speaker data file that lists default parameters
for popular cinema speaker models. Commonly used
configurations can also be saved on a disk, allowing you
to quickly load them on other DCMs.
Advanced Monitor Functions
In addition to audio monitoring of amplifier inputs and
outputs, DCMs include QSC’s exclusive “load fault”
detection. DCMs monitor all amplifier outputs and indicate
opens and shorts in the speaker system and wiring via
LED “load fault” indicators, providing confirmation that all
amplifiers outputs are functioning properly.
