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 simplifies system wiring and setup, significantly 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 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 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 processors throughout a theatre complex. All system configuration 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 amplifier inputs and outputs, the DCP includes QSC's exclusive “load fault” detection. The DCP 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 detects all amplifier 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.

Front Panel User Interface Details
The DCP 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 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 front panel speaker when the DCP is in "monitor mode" (indicated when the "SETUP" LED is not illuminated).
The global "Mute" button, when engaged, mutes all audio outputs. 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 all audio outputs.
Setup Overview
Initial configuration of the DCP 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 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 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-sync 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 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 offers a variety of accessibility options for configuring and managing the product and an entire cinema sound system locally or remotely. Local DCP configuration and system management are provided through directly applied connections to the DCP via universal serial bus (USB), the DCP 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 3rd party API or SNMP.
Basic configuration of the DCP product is performed through the USB interface on the product rear panel. The system designer connects to the DCP'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 front panel touch-control 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) via the product's rear panel USB interface.

Appendix A: DCP Serial Port Automation Control Protocol Rev 2.0
Description
This appendix describes the serial port automation control protocol for managing QSC's DCP 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 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 rear panel.
1.1 Communication Settings
The serial port settings required to communicate with the serial interface on the DCP are as follows:
- Baud rate of 115200 bits per second
- 8 Data Bits
- No Parity
- 1 Stop Bit
- Flow Control: none
- 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 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 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 all DCP products. Serial commands prefixed by “dcp100” and “dcp200” are also supported by all DCPs.
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
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 firmware (in the form: major.minor.build).
Example:
To read the DCP 300 firmware version:
cmd>dcp300version=
Return value:
dcp300version=1.00.0039
