[. . . ] OWNER'S MANUAL models D600 D800 D1200 D2400 CONGRATULATIONS Congratulations for choosing a Directed Audio power amplifier from Directed Electronics, the industry leader in high quality automotive security and audio equipment since 1990. Directed Audio power amplifiers continue to set new standards of performance, reliability, and affordability in the mobile electronics industry. Featuring high-efficiency MOSFET power supplies, flexible on-board crossovers, and state of the art audio design, Directed Audio power amplifiers will excite and delight the mobile sound enthusiast with years of high-quality audio reproduction. Directed Audio power amplifiers come with a two-year limited warranty if installed by an authorized Directed dealer. [. . . ] Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged. 8. LPF Control - Controls low pass filter cutoff from 30Hz to 250Hz. Phase Switch - 0° or 180° selectable for switching the phase output to the woofer. LED/FAN Connector - Allows connection of an optional LED light bar or optional cooling fan for the amplifier. Status LED - Will illuminate GREEN to indicate the amplifier is on and operating normally, and will be illuminated RED if the amplifier shuts down due to short circuit, DC offset, or overheating detected by onboard protection circuitry. © 2004 Directed Electronics, Inc 7 FIGURE 1--AMPLIFIER CONNECTIONS/CONTROLS D600/D800 FRONT 1 2 4 5 6 7 8 9 10 11 D600/D800 FIGURE 2--AMPLIFIER CONNECTIONS/CONTROLS D1200/D2400 FRONT 1 2 3 4 5 6 7 8 9 10 11 D1200/D2400 FIGURE 5--LED/FAN HARNESS BLACK BLUE BLACK RED + + TO LEDs TO FAN 8 © 2004 Directed Electronics, Inc REAR PANEL CONNECTIONS 1. Fuses - 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. The D600 uses 1-40A fuse, the D800 uses 2-25A fuses, the D1200 uses 2-30A fuses, and the D2400 uses 3-30A fuses. (+) 12 Volt Power - 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. 2. 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. Speaker Terminals - Connect subwoofers to these terminals. (Refer to the Speaker Wiring Diagrams section of this guide. ) 2. Remote Turn On - This terminal turns on the amplifier when (+) 12 volt is applied to it. (Refer to External Synced Bridged section of this guide for amplifier and speaker connection diagrams. ) NOTE: Amplifiers in this combination can only be connected in matched pairs. Multiple matched pairs may be added to drive separate subwoofer loads in a given system. Combined Amplifiers Gain and Filter Settings NOTE: You MUST set the Subsonic, EQ, and other filter settings on the master amplifier to the same positions to achieve safe, optimal results. Adjustment guidelines are discussed in the Crossover and Gain Adjustment section of this guide. 12 © 2004 Directed Electronics, Inc PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS Refer to figure 5 for wiring details. Input Signal - Connect these RCA jacks as described in the Front Panel Connection section of this guide. Slave/Master Switch Set the slave/master switch on the master amplifier to the MASTER position. [. . . ] With the gain adjustment on the amplifier in the middle of its rotation, bring up the volume on your head unit to the 3/4 volume setting or until you start to hear distortion or clipping. If you hear distortion before you reach the 3/4 volume setting of your head unit, reduce the gain setting on the amplifier and start to raise the head unit volume again. When you can listen to the music at or slightly above 3/4 on your head unit without audible distortion, slowly raise the gain of the amplifier until distortion is heard, then back off the gain until the distortion is not audible. This setting will allow you to reach full output with all but the quietest of source material, while avoiding excessive noise in the system. [. . . ]
