Introduction

QSC’s DCP 300 is a powerful solution for today’s D-Cinema audio systems. From server to speakers, the DCP 300 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 300 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 300 optimizes loudspeaker performance while simplifying cinema sound system wiring and conﬁguration. The DCP 300 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 300 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 300 is more than an audio processor. Whether designing a system for a single auditorium or designing a large multiplex, the DCP 300 offers the ﬂexibility in conﬁguration, networking, audio distribution and advanced management services to get the job done.

• SD memory card for quick unit swap – restores all settings

• Multiple bypass modes – routes audio around failed components to ensure that the show will go on

• DSP presets for QSC’s DCS speakers for great “out of the box” performance and reduced setup time

• Crossovers support active 2-way, 3-way or 4-way systems

• QSControl.net™ software (including Venue Manager, QSCreator, Notify and API for 3rd Party control systems) offer ultimate ﬂexibility in

management and allow for the creation of custom control screens, remote access, fault reporting and diagnosis

• Easily integrates with existing ﬁlm processors for dual ﬁlm/digital projection systems

• CobraNet offers digital non-sync routing and future expansion capability

• Continued development of software and ﬁrmware will add new capabilities via easy updates

Digital Signal Processing

The DCP 300 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 300 greatly simpliﬁes system wiring and setup, signiﬁcantly reducing installation time and labor cost. Input to the DCP 300 is provided via standard DB-25 cables from the D-Cinema server and/or 35 mm cinema processor. Connections to DCA ampliﬁers 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 300 processors simplify setup 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, or redistributed across a network,

allowing you to quickly load them into other DCP 300 processors throughout a theatre complex. All system conﬁguration data maybe saved to an SD memory card, allowing easy transfer of settings to a new (backup) DCP 300, should replacement ever be required.

Advanced Monitor Functions

In addition to audio monitoring of ampliﬁer inputs and outputs, the DCP 300 includes QSC’s exclusive “load fault” detection. The DCP 300 monitors all ampliﬁer outputs and indicates opens and shorts in the speaker system, providing conﬁrmation that all ampliﬁer outputs are functioning properly. Further, the DCP 300 detects all ampliﬁer clipping and protect modes and heat sink temperature for reporting via a QSControl™ Ethernet monitoring system.

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.
