HARDWARE DESCRIPTION- Front Panel FRONT PANEL The front panel of the DCM series resembles traditional cinema monitor products. This provides the projec- tionist a well known and easy to understand interface. Power Switch: The power on/off switch is the master control for the DCM and the amplifiers connected to it. Amplifiers must be connected to the DCM with DataPort cables and power switches must physically be in the “on” position. The DataPort connection to DCA amplifiers have a standby contro

HARDWARE DESCRIPTION- Front Panel FRONT PANEL (continued) Monitor Source Selection Switches: Pressing any of the Monitor Select buttons will either select or deselect the corresponding (marked) signal for monitoring. Each button can select either the Proces- sor signals (input to the DCM) or the Amplifier signals (output to the speakers), depending on the current selection of the PROC/AMP switch. LEDs provide confirmation of the active monitor source for each of the cinema channels. If no LED is

HARDWARE DESCRIPTION- Front Panel FRONT PANEL (continued) Diagnostics Check Button and Indicators: The Diagnostics / Indicator section includes an ex- tremely simple method of verifying proper system operation and performing basic troubleshooting. The Power LED shows whether the DCM unit is on or off. The Input Clip LED is helpful in verifying that the cinema format processor is not over-driving the DCM input circuitry. The Load Fault indicator is a unique and powerful feature which verifies tha

HARDWARE DESCRIPTION- Front Panel FRONT PANEL (continued) Test Jacks: The Test jacks give you access to any of the signals being sent to the front panel speaker (before the gain potentiometer). These signal levels are at the exact same level as the cinema processor output signals (unity gain) and can be used as a test point for system calibration. Emergency Bypass: This is an extremely powerful feature. If there should ever be a problem with the DCM or system cabling, you have the ability to byp

HARDWARE DESCRIPTION- Rear Panel REAR PANEL Amplifier DataPorts: One QSC amplifier DataPort includes all connections required to send two channels of audio from the DCM to the amplifier input circuitry, and current and voltage information back from the two speaker terminal outputs. Also included on this connector is remote on/standby control of the amplifier which allows the DCM to act as a master system power controller. Custom-length DataPort cables with individually shielded-pair construction

HARDWARE DESCRIPTION- Rear Panel REAR PANEL (continued) From Processor Output: This connection is from the cinema processor, and is the input source of all film sound into the DCM unit. The 25-pin connector is an industry standard type and pinout, and will connect into your system very easily. These cables are available from several cinema supply houses. RS-232 Connection: This connects to the RS-232 serial port on the host PC. All of the crossover functions and many other features can be viewed

SOFTWARE DESCRIPTION DCM MANAGER WINDOWS SOFTWARE To access the powerful crossover and system calibration functions of the DCM hardware, you must use the DCM Manager control software. A 9-pin male to female serial data cable is also needed to connect your PC to the DCM. One of the computer’s available COM ports (RS-232) provides communications between the DCM Manager software and the DCM hardware. The PC must meet the minimum System Requirements outlined on page 5. A typical cinema installation

INSTALLATION- Rack Mounting RACK MOUNTING Rack mounting of the DCM is optional. Four, self-adhesive rubber feet are included with your DCM for non- rack 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 activa

INSTALLATION- Rear Rack Ears (optional accessory) SUPPORTING THE REAR OF THE DCM (requires optional hardware) For mobile and touring use, it is extremely important to support the rear of the DCM. The chassis and rack can be damaged if the DCM is not properly supported. Unless the DCM is being installed in its final, fixed location, QSC strongly recommends supporting the rear of the unit. Rear rack ears, required hardware, and a separate instruction sheet are available from QSC’s Technical Servic
