TD-000371-00-A 3 Introduction The DXP adds new capabilities to the DCP line of Digital Cinema Processors, creating a powerful solution for today’s networked D-Cinema audio systems. From server to speakers, the DCP and DXP combine to offer 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. A single DXP provides all signal processing and monitoring functions for up to 12 DCA Amplifiers connected via DataPort connectors. The DXP also offers relays and contact closure inputs to interface with automations and other theatre systems like masking, dimmers, and curtain, as well as a Mic/ Line input to facilitate connection of podium microphones in multi-use facilities. The DCP and DXP communicate via CobraNet on a standard Ethernet infrastructure. Up to two DXP's may be connected to each DCP. The DXP requires a DCP for operation. The DXP provides advanced DSP presets for QSC’s Digital Cinema Speakers (DCS), the DXP optimizes loudspeaker performance while simplifying cinema sound system wiring and configuration. The DXP can provide crossovers for bi-amp, tri-amp or quad-amp operation or it can be used to power full range systems like surround channels. The use of standard Ethernet infrastructure allows the power amplifiers for the screen channels and subwoofers to be mounted near the speakers, eliminating long and expensive speaker cables and conduit. The DataPort connection through the DXP allows the remote-mounted amps and speakers to be fully monitored and controlled from the DCP. The DCP/DXP combination is more than an audio processor. Whether designing a system for a single auditorium or designing a large multiplex, the DCP and DXP together offer the flexibility in configuration, networking, audio distribution and advanced management services to get the job done. Features • The DXP accepts 16 Digital inputs via CobraNet. It supports crossover processing for up to 5 screen channels or up to 6 Auxiliary (point source) channels. • Analog Mic/Line Input • Compatible with all existing QSC DCA amplifiers • Dual internal power supplies seamless recovery in the event of a failure • Continued development of software and firmware will add new capabilities via easy updates Digital Signal Processing The DXP digital signal processing capability outperforms traditional analog crossovers and equalizers for optimized speaker performance. Crossover frequency, 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. Full range outputs for surround channels are also supported. Less Wiring, Faster Setup The DXP greatly simplifies system wiring and setup, significantly reducing installation time and labor cost. Input to the DXP is provided via standard Ethernet hardware via CobraNet from the associated DCP. Digital audio is routed over the network from the DCP to the DXP. The use of QSC's HD-15 DataPort cables to connect the DCA amplifiers to the DXP speeds installation as all traditional XLR and barrier strip terminations are eliminated. DCP and DXP 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 easy transfer of settings to the DXP. All configuration data may be saved to an SD memory card in the DCP, allowing easy transfer of settings to a new (backup) DCP or DXP, should replacement ever be required. Advanced Monitor and Control Functions In addition to audio monitoring of amplifier inputs and outputs, the DXP includes QSC’s exclusive “load fault” detection. The DXP monitors all amplifier outputs and indicates opens and shorts in the speaker system, providing confirmation that all amplifier outputs are functioning properly. In addition, the DXP detects all amplifier clipping and protect modes, and heat sink temperature. The DXP can also turn amps off and on, and control external devices via the four relay outputs. DCP Connect applications for iOS and Android mobile devices provide system control, fault reporting, and diagnosis, accessible through remote wi-fi network access throughout a cinema multiplex.

DXP Product Carton Contents 1. DXP 2. Hardware User Manual 3. IEC power cord and wire cord retainer 4. Euro style connector plug kit Mounting The DXP product is designed to be mounted in a standard 19" (480 mm) equipment rack and requires 1 vertical rack space (1 RU) (refer to IEC 60297 for additional rack dimensions and design details). Rack mounting provides the DXP with stability and a convenient means for dressing the cables connecting to the product. Some rack systems also provide climate control and/or conditioned power. Rack mount the DXP product by supporting it from underneath while aligning the four front panel mounting holes (in the rack ears) with the threaded screw holes in the rack rails. Install all four mounting screws and washers and tighten securely. The DXP product comes with rear rack support ears. Ensure that these rear mounting points are securely fastened to rear rack rails or rack side walls. Configuring the DXP DCP Manager™ is used to configure the DCP/DXP system. This includes configuring the device properties, the DSP objects, audio and control I/O and Presets. The network communications properties and audio networking features can also be configured using DCP Manager™. Refer to the DCP Hardware User Manual for instruction on the installation of DCP Manager, and the DCP Manager™ application Help Files for additional information on product configuration, management and network connectivity. NOTE: The DXP does not store any configuration information – configuration information is loaded from the DCP whenever a valid control connection is established. Additionally, the DCP will perform any necessary firmware updates automatically when it connects to the DXP. Once the basic DCP/DXP 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 DCP/DXP 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 Connections AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the DXP product. Plug the AC line connector into an AC outlet. The power supply on the DXP product will accept from 100 to 240V, 50 to 60 Hz. If a different type of IEC power cord is required than that supplied with the product, consult QSC’s Technical Services Group. — Figure 3 — TD-000371-00-A 7 CobraNet Network Connect one end of a data communications cable terminated with an RJ45 plug into the CobraNet™ Primary receptacle on the rear panel of the DXP product. Ensure that the lock tab on the cable engages with the RJ45 receptacle on the rear panel DXP connector. For systems requiring redundant network connections, connect a second data communications cable terminated with an RJ45 plug into the CobraNet™ Secondary receptacle on the rear panel of the DXP product. NOTE: Data communications cabling must be rated CAT-5 or better for all CobraNet™ connections. — Figure 4 — Automation Inputs The automation inputs use a 2-terminal Euro style (a.k.a. Phoenix) receptacle. The Automation Inputs can be connected to relay contacts or a switch and require a 2-terminal Euro style plug. The DXP rear panel label provides all necessary signal information. The negative terminal of each receptacle is at chassis potential. Relay Outputs Four relay outputs are provided via two 3-terminal Euro style (a.k.a. Phoenix) receptacles. Relay contacts are floating and rated for 30 VDC at 1A. Each output includes one common terminal, one normally open contact (NO), and one normally closed (NC) contact. These terminals are labeled C, NO and NC, respectively on the DXP rear panel. When the relay is not energized, the C terminal is connected to the NC contact and the NO contact is not connected. When the relay is energized, the C terminal is connected to the NO contact and the NC contact is not connected. NC DataPorts NO QSC DataPorts on the DXP 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. To connect a DataPort cable between a DXP DataPort and an amplifier DataPort, attach the cable’s male connectors to the HD15 ports and finger tighten the thumb screws on the connectors. NOTE: Although 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. C — Figure 5 — — Figure 6 — Mic/Line Input A single Mic/Line Input is accessible on the DXP rear panel. This input can be used for mono non-sync 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 or via the DXP front panel interface. The Mic/Line Input uses a standard 3-conductor XLR receptacle. NOTE: The Mic/Line input uses standard XLR cables that are readily available through retailers specializing in musical equipment, pro audio or home electronics. — Figure 7 — TD-000371-00-A 8 Specifications Refer to the individual sections in this document for more information.
