[. . . ] RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 250 mV and 8 volts. Speaker Load Select - Set 1 or 2/4 ohm to match the stereo load impedance of the system. Fan Port - connection port for FIGURE 1--AMPLIFIER CONNECTIONS 1200T FRONT connecting external, 12v DC brushless fan. ESP Port - For connecting the amplifier to ESP-2 alarm or second 1200T amplifier. Remote Level - Optional accessory which allows the level to be adjusted remotely (usually located for control by the vehicle's driver). 1 OUTPUT INPUT R 2 3 SPEAKER LOAD SELECT 1 2/4 45 6 - + ESP FAN PORT REMOTE LEVEL L © 2004 Directed Electronics, Inc 7 REAR PANEL CONNECTIONS 1. Speaker Out Terminals - Connect the speakers to these terminals. (Refer to the Speaker Connection section of this guide. ) 2. Power LED - This LED will illuminate Green to indicate the amplifier is on and operating normally. The LED will extinguish if the amplifier is off or if the amplifier shuts-down due to short circuit, DC offset, or overheating. One Ohm LED - This LED will illuminate when the 1-ohm mode is selected. Fuse 30A x 3 - These fuses protect the amplifier against internal electrical damage and are meant to protect the amplifier only. All other power connections should be fused at the source. (+) BATT - Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery. WARNING: Always protect this power wire by installing a fuse or circuit breaker of the appropriate size within 12 inches of the battery terminal connection. 6. REM (Remote Turn On) - This terminal turns on the amplifier when (+) 12 volt is applied to it. Connect it to the remote turn on lead of the head unit or signal source. If a (+) 12 volt remote turn lead is not available, a Remote Power Adapter (P/N #55000) can be used to supply a remote turn on signal. DO NOT connect this terminal to constant (+) 12 volt. GND (Ground) - Connect this terminal directly to the sheet metal chassis of the vehicle using the shortest wire necessary to make this connection. Always use wire of the same gauge or larger than the (+) 12 volt power wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this wire. DO NOT connect this terminal directly to the vehicle battery ground terminal or any other factory ground points. 8 © 2004 Directed Electronics, Inc FIGURE 2--AMPLIFIER CONNECTIONS 1200T REAR 1 L 1 MIN 2, 3 R 4 FUSE 30A x 3 567 + BATT REM GND POWER BRIDGED 2 MIN ONE OHM TOP PANEL FEATURES Control Panel Cover Remove/Install The gain and filter controls are located under a control panel cover on top of the amplifier. [. . . ] For subwoofer applications, try and keep the setting low enough to prevent image smearing (you should not be able to hear male voices from the subwoofer) but not so low as to create a gap between the subwoofer and the mid-bass/midrange speakers. For mid-bass/midrange settings, try to keep the setting low enough to keep your sound stage in front of you, without overdriving the speaker. It will be to your advantage to spend some extra time with this adjustment, listening to familiar music or system set-up discs to achieve the kind of musical reproduction that you prefer. The gain adjustment allows you to set proper signal match for clean, quiet amplifier operation. [. . . ]
