[. . . ] Digital Cinema Monitor & Crossover System USER MANUAL DCM-1 DCM-2 DCM-3 DCM Series TD-000106-00 Rev. B *TD-000106-00* 1 IMPORTANT SAFETY INSTRUCTIONS & EXPLANATION OF SYMBOLS 1- Read these instructions. 5- Do not use this apparatus near water. 7- Do not block any ventilation openings. Install in accordance with QSC Audio Product's instructions. [. . . ] A typical cinema installation should require this setup procedure ONLY during the initial installation of the system. One particular advantage of the DCM Manager software and DCM hardware is the ability to calibrate one DCM-based cinema system and easily download ALL of these settings to any number of additional DCM units in venues that are similarly equipped. To aid in calibrating the crossover settings, the DCM Manager control software includes a database including many well known cinema speakers. This data will automatically set the DSP filters and transducer alignment delay settings within the DCM hardware according to the settings recommended by the speaker manufacturer for optimum sound performance. Select speakers for each of the physical locations (L, C, R, SL, SR, SUB), and a large portion of the system calibration is finished!NOTE: QSC updates these files regularly as new models are introduced from speaker manufacturers or settings are improved.

Four, self-adhesive rubber feet are included with your DCM for nonrack mount applications. If using the DCM in non-rackmount applications, we recommend the rubber feet be installed on the bottom of your DCM to minimize the chances of scratching any supporting surface. To use the self-adhesive feet: peel off the protective backing from the foot, place near one of the corners on the bottom, and press firmly to activate the pressure-sensitive adhesive. If rack mounting the DCM, secure the DCM to the rack rails using four machine screws and washers of the proper size. Most US rack equipment accepts #10-32 machines screws; length used depends upon application. The DCM will require 3-RU (rack units) of space. [. . . ] NOTE: If the DCM unit is okay, place the Bypass switch back to the NORMAL position and the Load Fault indicator will light (after a few minutes) if there was an open- or short-circuit in the speaker cables. NOTE: The Emergency Bypass circuitry in the DCM does not require power to operate. Even if the DCM loses power, signals can be bypassed to the center channel as long as the remaining required equipment is functioning properly. If the DCM fails to turn on when the Power switch is set to the "on" position. . . . [. . . ]
