User manual DEI 1200T

[. . . ] During this one-year period there will be no charge for this replacement PROVIDED the unit is returned to Directed, shipping pre-paid. This warranty is non-transferable and does not apply to any unit that has been modified or used in a manner contrary to its intended purpose, and does not cover damage to the unit caused by installation or removal of the unit. This warranty is void if the product has been damaged by accident or unreasonable use, neglect, improper service or other causes not arising out of defects in materials or construction. ALL WARRANTIES INCLUDING BUT NOT LIMITED TO EXPRESS WARRANTY, IMPLIED WARRANTY, WARRANTY OF MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE, AND WARRANTY OF NONINFRINGEMENT OF INTELLECTUAL PROPERTY ARE EXPRESSLY EXCLUDED TO THE MAXIMUM EXTENT ALLOWED BY LAW, AND DIRECTED NEITHER ASSUMES NOR AUTHORIZES ANY PERSON TO ASSUME FOR IT ANY LIABILITY IN CONNECTION WITH THE SALE OF THE PRODUCT. [. . . ] Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can't deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system. 6 © 2004 Directed Electronics, Inc FRONT PANEL CONNECTIONS/STATUS LED 1. RCA Output Jacks - These pass through RCA jacks can be used to send a signal to a second amplifier. 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. 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. (+) 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. 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. [. . . ] This increases the output of a subwoofer by as much as 3 dB by increasing the mechanical power handling of the subwoofer. Depending on the type of enclosure the subsonic filter can increase the useable low frequency output by an additional 10 dB!Acceptable boost levels are determined by the type of enclosure used, wattage of the amplifier, and the woofer's excursion capability. To adjust this filter, place the Subsonic Filter switch to the IN position and turn the Subsonic Frequency adjustment to the desired frequency (15­50 Hz). [. . . ]
