Introduction
QSC’s DCP is a powerful solution for today’s D-Cinema audio systems. From server to speakers, the DCP offers a complete set of tools to facilitate all the signal processing, audio distribution, monitoring and automation control services required in a modern D-Cinema sound system.
The DCP builds on the legacy of QSC’s DCM and BASIS™ 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 DSP presets for QSC’s Digital Cinema Speakers (DCS), the DCP optimizes loudspeaker performance while simplifying cinema sound system wiring and configuration. The DCP
covers cinema systems ranging from three to five screen channels, and is configurable for bi-amp, tri-amp or quad-amp operation. Though optimized to receive audio content directly from a D-Cinema server, the DCP is also compatible with all analog cinema processor formats including Dolby® Digital Surround-EX and DTS-ES and features a 10 channel analog input for integration with 35 mm audio systems.
The DCP is more than an audio processor. Whether designing a system for a single auditorium or designing a large multiplex, the DCP offers the flexibility in configuration, networking, audio distribution and advanced management services to get the job done.

Digital Signal Processing
The DCP 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. Active 2-way, 3-way and 4-way crossovers are available. Advanced crossover presets for QSC DCS speakers speeds system set-up and ensures maximum performance.

Less Wiring, Faster Setup
The DCP greatly simplifi es system wiring and setup, signifi cantly reducing installation time and labor cost. Input to the DCP is provided via standard DB-25 cables from the D-Cinema server and/or 35 mm cinema processor. Connections to DCA amplifi ers for input and monitor signals are made through a single QSC DataPort cable (VGA-style cable). All traditional XLR and barrier strip terminations are eliminated. DCP processors simplify setup by using a menu-driven, PC-based software program for confi guration. The program includes a speaker data fi le that lists default parameters for popular cinema speaker models. Commonly used confi gurations can also be saved on a disk, or redistributed across a network, allowing you to quickly load them into other DCP processors throughout a theatre complex. All system confi guration data may be saved to an SD memory card, allowing easy transfer of settings to a new (backup) DCP, should replacement ever be required.
Advanced Monitor Functions
In addition to audio monitoring of amplifi er inputs and outputs, the DCP includes QSC’s exclusive “load fault” detection. The DCP monitors all amplifi er outputs and indicates opens and shorts in the speaker system, providing confi rmation that all amplifi er outputs are functioning properly. Further, the DCP detects all amplifi er clipping and protect modes and heat sink temperature for reporting via a QSControl™ Ethernet monitoring system or via SNMP.
The QSControl.net™ suite of applications allows for the creation of custom control screens via “drag and drop” design using the QSCreator software application. Screens can be designed to provide intuitive fault reporting and diagnosis that is accessible through remote network access. In addition, QSC’s PoE-enabled NAC 100 Ethernet remote control panel provides remote operation and status throughout a cinema multiplex from anywhere on the local network.
