Please take the time to familiarize yourself with this product by carefully reading this manual. Most questions can be answered by reading and following the instructions contained herein. Because of the multitude of products from other manufacturers, this manual cannot possibly cover all the different configurations and hookups. [. . . ] An exciter light changeover has at least 3 dB more circuit noise than an electronic changeover and is NOT recommended in high quality systems. Non-Sync Music Connections The non-sync music inputs for the MOD 7a are run through the Circle Surround matrix to generate 5. 1 channels of auditorium music. Connect your stereo music source (CD player, tape, etc. ) to the MUSIC LEFT and MUSIC RIGHT inputs on the back of the MOD 7a. Occasionally, a theater may use a monaural sound player such as a background music cartridge player or satellite music service that does not have stereo capabilities. In this event, connecting a mono signal into both LEFT and RIGHT MUSIC inputs will generate music in the center channel only. SMART recommends using a stereo distribution amplifier such as the SMART DA226 to feed signals from one music source to multiple sound processors. Automation Connections Connect the format pins on the AUTOMATION terminal strip of the MOD 7a to the systems corresponding automation relay terminals. A momentary ground contact on one of the FORMAT SELECT inputs on the rear of the MOD 7a will switch the processor to any desired format, including music. The EX format select terminal will toggle between EX ON and EX OFF when pulsed to ground. Note: The MOD 7a powers up in Non-Sync Music mode. Muting Function A convenient MUTE terminal in the AUTOMATION section of the back panel allows all output channels of the MOD 7a to be silenced whenever this terminal is grounded. Connecting the MOD 7a to a Reverse Scan Two Projector Systems Connect the CHANGEOVER and GROUND terminals on the MOD 7a AUTOMATION terminal strip to the booth automation changeover relay terminals. Projector changeover is accomplished by using only a single pair of wires and either a manual switch or relay contacts in the automation system. A relay closure in the automation equipment will execute a changeover by grounding the CHANGEOVER terminal. Run a twoconductor shielded cable to the dry contacts of the automation projector changeover relay. On the other end, connect one wire to the CHANGEOVER terminal on the MOD 7a. Ground the other wire to the nearest ground terminal on the MOD 7a. Connect the shield of the wire, on the MOD 7a end, to a ground terminal. Cut off the shield on the automation end. When the automation relay closes, Projector Two of the MOD 7a will be enabled, and the first pair of stereo preamplifiers (Projector One) will be disabled. Releasing the relay will cause the reverse action to occur. In other words, Projector One is always ON until the CHANGEOVER terminal is grounded. The CHANGEOVER 11 MOD 7a STEREO PROCESSOR Digital Player Connections The MOD 7a has six inputs (Left, Center, Right, Left Surround, Right Surround and Sub) via a female DB25 connector marked DIGITAL INTERFACE. [. . . ] However, any format may be overriden by simply pushing one of the Format buttons located on the front of the MOD 7a. DEFAULT PROGRAM SELECTION The MOD 7a can be programmed to power up in any desired format. While the unit is powered up, set the EX mode as desired. Then, press and hold the format button for the desired default format for two seconds. [. . . ]
