[. . . ] DCP 300 Digital Cinema Hardware User Manual DCP 300 ­ Digital Cinema Processor TD-000285-00 REV B *TD-000285-00* IMPORTANT SAFETY PRECAUTIONS AND EXPLANATION OF SYMBOLS WARNING! The lighting flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous" voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in this manual. SAFEGUARDS Electrical energy can perform many useful functions. This unit has been engineered and manufactured to assure your personal safety. [. . . ] Refer to the Help Files for instructions on how to configure the basic operating parameters of the DCP 300 (source inputs, format, presets, etc). 4. Attach Amplifiers Connect DataPort outputs on the DCP 300 rear panel to DataPort inputs on QSC's DCA or PL3 Series amplifiers using QSC approved DataPort cables. 7 Setup Overview 5. Connect Audio Connect cinema audio sources to the appropriate DCP 300 rear panel input connectors. Main sources can come from digital content servers or analog film processors. Additional analog and digital inputs are provided for alternative content sources, live feeds, DVD players, mic/paging sources etc. Connect the Hearing Impaired and Visually Impaired special mix outputs and/or the Monitor Output feed to appropriate external devices as needed. 6. Connect Automation Connect appropriate external control devices to the DCP 300's automation Inputs. Connect the Logic Outputs and/or Relay Outputs to any external devices to be controlled. 7. Complete Installation Remove protective film covering the touch panel LCD surface. Insert the included SD Card into the rear panel receptacle. The SD Card provides DCP 300 configuration storage for quick unit service/replacement. 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. 8 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 (QSControlTM). 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.
