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.
Features
• Digital inputs accept up to 16 channels of AES-3 audio from a D-Cinema server or other digital audio 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 with 2-way, 3-way 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
• 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,
3
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.

Front Panel User Interface Details
Front Panel UI
The DCP 300 front panel includes a 480 x 272 pixel, 4.3", color TFT display with a touch control interface and a 16:9 wide screen aspect ratio. The
touch control “user interface” allows authorized system operators to recall previously configured presets, adjust levels, change monitor tap points etc.
The “Monitor Volume” knob is used to manipulate these parameters when the DCP 300 is in “setup mode” (indicated when the “SETUP” LED in the
middle of the Monitor Volume knob is illuminated green).
The Monitor Volume is also used to change the level of the amplified monitor signal feeding the DCP 300 front panel speaker when the DCP 300 is in
“monitor mode” (indicated when the “SETUP” LED is not illuminated).
The global “Mute” button, when engaged, decouples all DataPort outputs from their amplifiers by opening a relay in the signal path. Engagement of
the Mute button is indicated when the red LED in the mute button cap is illuminated. Normal operation (non-muted) is indicated through illumination
of the Mute button cap with a green LED.
The large rotary encoder knob to the right of the touch control LCD is the master level control for the auditorium sound system. Adjusting this control
manipulates the level of the audio signal fed to the DataPort outputs.
Setup Overview
Initial configuration of the DCP 300 is performed through QSC’s DCP Manager™ software, which must be installed on a Windows® PC or laptop
computer. Once the software is installed on the computer, the computer can then be connected to the DCP 300 product via a USB connection.
A system designer would typically begin high-level configuration by defining the basic system topology and distribution of audio within the DCP
Manager application. This involves selecting the audio sources for the DCP 300 program inputs, auditorium sound format, amplification and speaker
design and whether additional devices (such as BASIS™ devices) are included in the system design for the purposes of expanding the quantity of
DataPort outputs or for locating the amplifiers remotely for example: outside of the projection booth… behind the projection screen. Presets can be
created to accommodate multiple audio sources or distribution topologies (i.e.., to support different configurations for the main theatre presentation
and for alternative content/non-synch audio) and/or to support multiple auditorium mixes or multi-use applications.
Once the high-level configuration is complete, the rest of system can be connected to the DCP 300 and/or powered up and completion of the DSP
configuration, assignment of levels, application of architectural delay etc. and system tuning can commence.
Note that recalling of system presets and adjustment of system parameters such as output and monitor levels, monitor tap points etc. can be made
through the front panel user interface (the touch control LCD and associated rotary encoders) by authorized users.
The Setup Overview on the following pages is a general application guide showing the installation steps required for a basic system. Refer to the Help
Files in DCP Manager and the QSControl.net™ suite of applications for detailed setup and configuration instructions and for system examples. The
QSC Cinema Products web pages are also a good source of information for application notes and system design assistance.

Configuration and Networking
The DCP 300 offers a variety of accessibility options for configuring and managing the product and an entire cinema sound system locally or remotely.
Local DCP 300 configuration and system management are provided through directly applied connections to the DCP 300 via universal serial bus
(USB), the DCP 300 front panel touch-control LCD or through a local Ethernet link (QSControl™). Remote and system-wide management are possible
through more sophisticated network implementations and/or via wide area network (WAN) topologies, Internet access or 3rd party subscription
services that make use of the DCP 300 3rd party API.
Basic configuration of the DCP 300 product is performed through the USB interface on the product rear panel. The system designer connects to the
DCP 300’s rear panel USB port with a Windows laptop or PC running the DCP Manager software application. DCP Manager offers all the setup tools
and system management objects to configure the auditorium audio format, selection of audio source material, configure the DSP signal path, apply
crossovers, EQ etc., Define the routing of audio to the amplifiers, define the system speakers and speaker processing etc. Once the basic configuration
is complete, the system designer can define custom Presets that can be recalled for different auditorium setups. For example, a Preset can be created
for the primary presentation content. Another Preset can be created for non-sync or alternative content. And yet another Preset can be created for live
application use such as seminars or corporate events. Once these Presets are created they become accessible via the DCP 300 front panel touchcontrol LCD.
In addition to basic configuration, DCP Manager can be used to monitor health, status and performance of the local system (the directly connected
DCP 300) via the product’s rear panel USB interface.

Once the DSP signal chain and audio format are configured, the DCP 300 can be connected to an Ethernet LAN for local or remote management
using the QSControl.net™ suite of applications or via a custom application or control system using the DCP 300 3rd Party API.
A local Ethernet connection to a Windows laptop or PC that is running QSC’s Venue Manager Application provides the system designer with access
to status, health and performance of the local system. Changes to Presets, audio levels and some automation control objects can be made through
Venue Manager access.
DCP 300 firmware updates can also be performed through the Venue Manager Application. For more venue-specific needs, QSC’s QSCreator
Application allows the system designer to create custom control screens with varying levels of password protection (authentication rights). QSCreator
screens can be as elaborate as the system designer’s imagination and can be created to depict the physical layout of the auditorium or the entire
cinema complex.
Since the QSControl.net™ suite of applications provide accessibility to the DCP 300’s network interface, these applications can be used to manage
an entire sound system consisting of multiple DCP 300 products, QSC amplifiers, QSC speakers and other QSC network enabled products such
as BASIS, RAVE and DSP 300 series products. Management can be localized (within the theatre complex) or remote, depending on the network
implementation deployed.

QSC DataPorts on the DCP 300 rear panel are intended to interface to QSC amplifiers with v1
DataPorts. These are the all-capable DataPorts, which are included on DCA and PL3 series amplifiers.
All DataPorts use the HD15 connector format and connect to QSC amplifiers via data communications
cables having male HD15 connectors on both ends. These are commonly referred to as VGA cables.
Note: though many off-the-shelf VGA cables may work with satisfactory results, the QSC DataPort
specification requires that all conductors be present and that all audio I/O conductors be shielded.
Therefore, only QSC supplied DataPort cables should be used. A variety of lengths are available through
QSC’s Technical Services Group. To connect a DataPort cable between a DCP 300 DataPort and an
amplifier DataPort, attach the cable’s male connectors to the HD15 ports and finger tighten the thumb
screws on the connectors.
Ancillary Interfaces
A single Mic/Line Input is accessible on the DCP 300 rear panel. This input can be used for mono nonsynch sources or for connecting a microphone for local paging or announcements into the auditorium
or to support various corporate or live events requiring a microphone. Phantom power may be enabled
via DCP Manager™ configuration. The Mic/Line Input uses a standard 3-conductor XLR receptacle.
L/R analog line input connectors and a multi-channel digital S/PDIF input are accessible on the DCP 300
rear panel. These RCA connectors accommodate non-synch sources appropriate for alternative content,
advertising, corporate or live event feeds.
A USB Type B interface is provided for directly connecting to a Windows® PC or laptop. All configuration
and local management of the DCP 300 via DCP Manager software is performed through this portal.
Note: all ancillary interfaces use standard cables that are readily available through retailers specializing
in computer equipment, musical equipment, pro audio or home electronics.

Appendix A:
DCP 300 Serial Port Automation Control Protocol Rev 1.0
Description
This appendix describes the serial port automation control protocol for managing QSC’s DCP 300 Digital Cinema Processor. Serial port automation is
handled via ASCII text commands sent via RS-232 from an external device. All commands must be terminated with a CR [0Dh] or LF[0Ah].
NOTE: Settings manipulated via serial port automation commands may be overridden or modified by commands issued from the DCP 300 front panel
display, by commands sent over the network using QSC’s Third Party Control Protocol, or by triggers coming in through other automation inputs on
the DCP 300 rear panel.
1.1 Communication Settings
The serial port settings required to communicate with the serial interface on the DCP 300 are as follows:
• Baud rate of 15200 BPS
• 8 Data Bits
• No Parity
• 1 Stop Bit
• Straight through cable (not a null modem)
1.2 Command Protocol
A communication terminal program such as Hyper Terminal can be used for initial testing of the DCP 300 automation commands. After connecting the
serial port cable (no null modem) and configuring a communication session (you should see the following command prompt indicating that the DCP
300 unit is ready to accept serial automation commands, you may need to use a <CR> to see the prompt):
cmd>
1.3 Automation Command Reference
The following serial commands are currently supported by the DCP 300:
dcp300preset
Selects the preset specified (1 – 32). If no preset number is entered following the ‘=’ character, then the currently selected audio preset is returned.
Examples:
To select preset 1:
cmd>dcp300preset=1
Return value:
dcp300preset=1
To query currently selected audio preset (presets 1-16):
cmd>dcp300preset=
Return value:
dcp300preset=1
If invalid, disabled preset number, or out of range value entered:
cmd>dcp300preset=50
Return value:
dcp300preset=invalid
Note: Currently selected preset will remain active
dcp300mute
Turns the Master Mute on or off (1 = mute, 0 = unmute). If no value is entered following the ‘=’ character, then the current state of the Master
Mute is returned.
Examples:
To turn master mute on:
cmd>dcp300mute=1
Return value:
dcp300mute=1
17
To turn master mute off:
cmd>dcp300mute=0
Return value:
dcp300mute=0
To query current state of master mute:
cmd>dcp300mute=
Return value:
dcp300mute=1
If invalid or out of range value entered:
cmd>dcp300mute=a
Return value:
dcp300mute=invalid
Note: Current state of Master Mute will remain active
dcp300fader
Sets the Master Volume level to the value specified in dB (-90.0 to 10.0 in .5dB increments). If no value is entered following the ‘=’ character, the current Master Volume level is returned. If a ‘+’ character is entered following the ‘=’ character, then the volume is incremented by .5 dB (not to exceed
the maximum allowable volume of 10.0 dB). If a ‘–‘ character is entered following the ‘=’ character, then the volume is decremented by .5 dB.
Examples:
To set Master Volume to 5 dB:
cmd>dcp300fader=5.0
Return value:
dcp300fader=5.0
To increment volume by .5 dB:
cmd>dcp300fader=+
Return value (assuming volume previously set to 5 dB):
dcp300fader=5.5
To decrement volume by .5 dB
cmd>dcp300fader=Return value (assuming volume previously set to 5 dB):
dcp300fader=4.5
To query current volume:
cmd>dcp300fader=
Return value:
dcp300fader=4.5
If invalid or out of range value entered:
cmd>dcp300fader=20.0
Return value:
dcp300fader=invalid
Note: Master Volume will remain at current level
dcp300version
Returns the version of the DCP 300 firmware (in the form: major.minor.build).
Example:
To read the DCP 300 firmware version:
cmd>dcp300version=
Return value:
dcp300version=1.00.0039
