User manual DEI A802

[. . . ] OWNER'S MANUAL A802 A1004 models D2205 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. [. . . ] Subsonic - the OFF position takes the filter out of the system, the IN position places the the filter into the system (D2205). 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. LED/Fan - allows connection of an optional LED light bar or optional cooling fan for the amplifier. Sub Input/Line Out - selects RCA jacks (4) (Sub/Line Out) as either Subwoofer Input or Line Output. © 2004 Directed Electronics, Inc 7 FIGURE 1--AMPLIFIER CONNECTIONS -- FRONT 1 3 4 6 8 9 7 14 13 A802 2 1 3 4 17 6 8 9 7 10 14 13 A1004 2 2 3 4 5 6 7 8 9 10 11 12 13 D2205 1 17 16 15 14 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. The A802 uses 2-30A fuse, the A1004 uses 2-40A fuses, and the D2205 uses 3-40A fuses. For the Alarm to Amplifier, the Transmit and Receive wires must cross from one end to the other. Bitwriter® commands can control parameters such as Turn on Delay, Fan Control, Input Gain adjustment, and also place the amplifier into a monitoring state for commands from an ESP2 equipped alarm. Fan Control - AUTO - The fan will automatically turn on when the internal temperature exceeds approximately 40 deg C. Use the ON option if you are using the external FAN port to drive optional LED tubes. Service Code Display - The Directed ESP® Engine stores up to seven previous faults for later replay. The Service Code Display allows the installer to step through the fault history. - FLASH CODE ON LED - the last recorded fault is "replayed" on the ESP® Indicator LED. If the unit has never recorded a fault, the ESP® Status indicator will not flash. Note that this allows you to see previous faults prior by backstepping one at a time through the fault history. Input Gain Range - The sensitivity on the gain control can be limited to specific ranges. The DEFAULT position allows adjustment over the full range of amplifier sensitivities. Input Gain Adjustment - In the LOCK position, the gain range and gain control can be locked out to prevent accidental mis-adjustment. The © 2004 Directed Electronics, Inc 11 Default mode is UNLOCKED. Valet - Selecting ENABLE allows the amplifier to monitor valet signals from the alarm system. The amplifier will not power up once remote power is removed when the Valet monitoring mode is ENABLED and the alarm system has been set into Valet mode. Note: To make use of the Anti-theft or Valet features, the amplifier must "learn" which transmitters are associated with the currently used alarm system. [. . . ] For full-range and simultaneous stereo/mono bass applications, start by playing some music you are familiar with. With the gain adjustment on the amplifier in the © 2004 Directed Electronics, Inc 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.
