User manual SMART DEVICES COPYCAT 280-2 INSTALLATION

[. . . ] Please consult with your Dealer, Installer, Technician or the SMART factory for any unusual situations involving the connection and use of this product with equipment from other manufacturers. When properly connected and operated, this product should deliver outstanding results. SMART products are designed to deliver unsurpassed quality in workmanship and performance. The following information gives detailed instructions on the installation and operation of the SMART COPYCAT 280-2 stereo processor. [. . . ] DOUBLE CHECK your work to see that the solar cell leads arrive at the proper terminals. A reversal of leads will cause very strange results. You may hear the center channel information through the surround speakers, the surround through the stage, and the left channel out of phase with the right. This is a common error, so verify correct wiring before proceeding. terminal must be tied to ground to activate Projector Two. 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 COPYCAT 280-2. This necessitates that BOTH exciter lamps be lit at the same time. No exciter light changeover is provided in the unit. 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 COPYCAT 280-2 are run through the Circle Surround matrix to generate 5. 1 channels of auditorium music. SMART has interconnection cables available to connect the popular digital player systems to the COPYCAT 280-2. Simply plug the appropriate DB25 connector to the COPYCAT 280-2 DIGITAL INTERFACE port and the other DB25 connectors to the audio and control ports on the digital player. If you desire to make your own cables, here is the pinout for the DB25 connector. Digital Interface DB25 Pinout Pin 1 Left Pin 3 Center Pin 5 Right Pin 6 Left Surround Pin 7 Right Surround Pin 8 SubWoofer Pin 9 Mono Pin 10 Music Pin 11 Stereo A Pin 12 Digital Pin 13 Stereo SR Pin 14-25 Ground Another application for the digital input is for external sync sources. Sound interlock from a 35-mm reproducer or a single 16-mm projector may be fed into the DIGITAL INTERFACE and selected with the front panel DIGITAL format switch. Default Optical Selection External digital decoders available on the market have a function that instructs the processor to switch to an optical format in the event that the digital decoder fails or loses time code. When this happens, the digital decoder will pulse the appropriate terminal (MONO, STEREO A, STEREO SR, or MUSIC) to ground to alert the processor to switch to the optical format. The information pertaining to which format to default to is encoded in the digital soundtracks on DTS prints. On Dolby Digital, the default is SR. Monitor Interface The MONITOR INTERFACE Port is a male DB25 connector to which a booth monitor's processor inputs can be connected. The pinout is as follows: Pin 5 Right Rear/Overhead Pin 7 Left Rear Pin 12 +15 VDC Pin 13 -15 VDC Pin 15 Subwoofer Pin 17 Right Wall Pin 19 Left Wall Pin 21 Right Pin 23 Center Pin 25 Left Pins 2, 4, 6, 8, 10, 16, 18, 20, 22, & 24 Ground Output Connections The main OUTPUTS are labeled LEFT, CENTER, RIGHT, LEFT WALL, LEFT REAR, RIGHT REAR, RIGHT WALL, and SUB. Shielded cable should be run between these terminals and the next piece of equipment in the sound system (equalizer, amplifer, etc. ). [. . . ] Become familiar with all switches or breakers that control power to the sound equipment. The COPYCAT 280-2 is equipped with a power up muting circuit that allows time for the low level circuits to stabilize before enabling the processor outputs. This circuit prevents a "turn-on thump" from being passed to the auditorium speakers. However, since most amplifiers are not equipped with a comparable muting circut for the power down sequence, it is recommended that the amplifiers be turned off before the processor to avoid a "turn-off thump" in the auditorium.
