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. [. . . ] TWO PROJECTOR SYSTEMS - NO AUTOMATION: Rig a single pole, single throw switch between the CHANGEOVER terminal and a GROUND terminal. When the switch is open, Projector 1 will be active, when it is closed, Projector 2 will be active. NOTE : Changeover between projectors is done electronically in the MOD 8. 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 8 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 8. 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 8 to the system's corresponding automation relay terminals. A momentary ground contact on one of the FORMAT SELECT inputs on the rear of the MOD 8 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 8 powers up in Non-Sync Music mode as the factory default. Muting Function A convenient MUTE terminal in the AUTOMATION section of the back panel allows all output channels of the MOD 8 to be silenced whenever this terminal is grounded. 11 Connecting the MOD 8 to a Reverse Scan soundhead. Two Projector Systems Connect the CHANGEOVER and GROUND terminals on the MOD 8 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 8. Connect the shield of the wire, on the MOD 8 end, to a ground terminal. When the automation relay closes, Projector Two of the MOD 8 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. [. . . ] MUSIC SELECTION It is likely that the sound system will be turned on before the arrival of the first audience of the day. If the music player (CD player or tape machine) is running, music will be heard in the auditorium and on the booth monitor. PROGRAM SELECTION The automation should be set to select the proper formats when needed. However, any format may be overriden by simply pushing one of the Format buttons located on the front of the MOD 8. [. . . ]
