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.

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.

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, 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 the all audio 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.

8. Tune System

Once the basic DCP 300 operating conﬁguration is deﬁned and all of the connections are in place, it’s time to power up the rest of the rack, complete the DSP setup, tune the system and run through ﬁnal check.

Refer to additional information in this Hardware User Manual and in the software Help Files for further setup and conﬁguration details to complete this step.

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 or SNMP.

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. Remote management also available via SNMP.

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 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 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

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
