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 
35mm audio systems.  
 
The DCP 300 is more than an audio processor. Whether 
designing a system with 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.  
 
 

Features 

 

 

Digital inputs accept up to 16 channels of audio (AES-3) 
from a D-Cinema server or other digital source 

 

 

Networked audio I/O via CobraNet™ 

 

 

Analog inputs accept audio from film processors 

 

 

Additional analog inputs accommodate non-sync and 
Mic/Line sources 

 

 

Master volume and full 1/3 octave EQ on all channels 
(except subwoofer) 

 

 

Booth monitor with touch screen control for easy 
operation 

 

 

Digital loudspeaker crossovers 

 

 

Three or five screen channels – 2, 3 or 4-way crossovers 

 

 

Compatible with all existing QSC DCA amplifiers 

 

 

Dual internal power supplies with load sharing for 
seamless recovery in the event of a failure 

 

 

SD memory card for quick unit swap – restores all 
settings 

(not yet supported: expected Winter 2009)

 

 

 

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, 3 or 4-way systems 

 

 

QSControl.net suite of applications (including Venue 
Manager, QSCreator, Notify and API for 3

rd

 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 to the existing hardware with easy updates 

 

 

The DCP 300 is the heart of a new generation of QSC 
products designed expressly for the needs of D-Cinema 
sound systems 

 
 

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 insures maximum performance. 
 
 

Less Wiring, Faster Setup 

 
The DCP 300 greatly simplifies system wiring and set-up, 
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 35mm 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. DCP 300s 
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, or redistributed across a network, allowing you 
to quickly load them into other DCP 300s throughout a theatre 
complex. All system configuration data is saved to an SD 
memory card, allowing easy transfer of settings to a new 
(backup) DCP 300, should replacement ever be required 

(SD 

functionality is not yet supported: expected Winter 2009)

  

 
 

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. In addition,
