This DB25-type connection conforms to cinema industry standard pinout. Most common cinema processors use this DB25 connection standard, making connection to the DCM simple. Orient the DB25-type connector properly, push gently to seat the pins, then finger-tighten the retaining screws. Cinema processors that do not use standard DB25-type connection typically have adapter cables available. Check with the processor manufacturer. We recommended that you purchase a standard 25-pin cable from any of the well known cinema industry cable suppliers. FROM PROCESSOR OUT Pinout- Configuration: 25-pin SubD male to 25-pin SubD male.

The output signal is similar to levels that are output from a standard CD player. DCM-1 Terminals DCM-2 and -3 Terminals Output Level Impedance -11.8 dBu 50 ohms (200 mVrms) (±5%) Connect other end of cable according to equipment manufacturer’s instructions. Use balanced audio connections and high-quality, shielded, balanced audio cable for interconnecting the DCM and Hearing Impaired equipment. Balanced connections are less prone to noise pick-up than unbalanced connections. POWERED SUBWOOFER CONNECTION Screw terminal connections make it DCM-1 Terminals DCM-2 and -3 Terminals possible to send a balanced signal to a powered subwoofer. This signal is balanced and the circuitry is designed for long cable runs from the projection booth to the theater screen. The high-pass filtering and level adjustments are done by the DCM unit. NOTE: There will be no fault analysis or output audio monitoring available for the sub channel signal if this connection is used. Connect other end of cable according to equipment manufacturer’s instructions. Use balanced audio connections and high-quality, shielded, balanced audio cable for interconnecting the DCM and Powered Subwoofer equipment. Balanced connections are less prone to noise pick-up than unbalanced connections. INSTALLATION- Connections: Surround Insert SURROUND INSERT CONNECTION DCM-1 Surround Insert Connector Surround insert connections are provided for and Selector Switch connection to a Dolby Surround Processor. The surround insert connections are made using the TO SURROUND EX DECODER connection. Connect a cable between this connector and an external processor such as the Dolby SA-10. Signals will be routed out of the DCM to the processor and back into the DCM for output to the amplifiers. DCM-2 and -3 Surround Insert Connector TO SURROUND EX DECODER Pinout- Configuration (typical): 9-pin SubD female on DCM end to loose wires attaching to surround processor’s terminal strip inputs and outputs Pin# Signal Description 1 Surround Left Send 2 Surround Right Send 3 Signal Ground 4 Surround Left Return 5 Surround Right Return 6 Signal Ground 7 Signal Ground 8 Surround Back Left Return 9 Surround Back Right Return INSTALLATION- System Calibration SYSTEM CALIBRATION When installing a typical cinema sound system, most of the calibration involves the Cinema Processor. Refer to the user manual for the Cinema Processor that you are using. WARNING: Turn the Gain Controls on all of the system’s amplifiers all the way down until crossover settings and levels are verified! Connect a PC computer to the RS-232 connector, turn on the DCM unit, load the DCM Manager software and either load a full configuration file (if this theater uses the exact same settings as another theater), or select and enter all of the new data. The General, Amp, Speaker, and DSP Settings tabs must all be set correctly and downloaded to the DCM for the system to function properly. Once all system and crossover settings are correct in the DCM Manager software, you are ready to star...
