[. . . ] DCP Series DCP ­ Digital Cinema Processor Digital Cinema Hardware User Manual TD-000285-00 C *TD-000285-00* IMPORTANT SAFETY PRECAUTIONS AND EXPLANATION OF SYMBOLS WARNING! The lightning 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. This unit has been engineered and manufactured to assure your personal safety. Improper use can result in potential electrical shock or fire hazards. [. . . ] 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 ManagerTM 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 BASISTM 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. . . 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. 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. netTM 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. 10 Setup Overview 1. Unpack Carton Remove your DCP product from its carton and inspect it carefully. Make sure that the carton contents are complete and that there are no signs of shipping damage. Retain all packaging for future unit storage or for the unlikely event that service is needed. 2. Install Software Load the DCP Manager disc into a CD-ROM or DVD drive on a Windows® PC or laptop computer. Follow the installation instructions displayed on your computer's screen. Note: DCP Manager must be installed before connecting the DCP to a Windows PC or laptop computer. 3. Configure DCP After DCP Manager is installed, connect a USB cable between the DCP and the computer. [. . . ] The DCP 100 and DCP 200 vary only in some functionality, and quantity of connectors.
