10. 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. © 2003 Directed Electronics, Inc FRONT PANEL CONNECTIONS/CONTROLS N NNO OOT TTE EE: :: The step numbers listed below are referenced on the Input Wiring Diagram. 1.

FLAT does not attenuate any frequencies and is for full-range speaker systems. HPF attenuates low frequencies and is used for mid-range speakers and tweeters. LPF attenuates high frequencies and is used for subwoofers speakers. 5.

N NNO OOT TTE EE: ::The 2300X and 4600X amplifiers require that the system remote power be cycled off and on again to restart the amplifier after a protection shutdown. The 1500X amplifier will cycle off and automatically turn back on when the fault condition clears. The amplifier should be inspected for proper ventilation clearance on all sides of the amplifier (2inches). The speaker wiring should be inspected for any shorts. N NNO OOT TTE EE: ::The 1500X and 2300X amplifiers have one combined Power/Protection (BLUE/RED) LED, the 4600X amplifier has separate Power (BLUE) and Protection (RED) LEDs. © 2003 Directed Electronics, Inc © 2003 Directed Electronics, Inc 7 1 5 4 2 3 6 3 LPF HPF INPUT WIRING DIAGRAMS 1 5 4 2 3 6 X-OVER 8 © 2003 Directed Electronics, Inc 2 3 3 2 5 4 5 4 FOUR CHANNEL 4600X 1 1 6 6 POWER PROTECT LPF HPF CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Xtreme Series power amplifier by Directed Audio needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when fine-tuning the amplifier. • For full-range and simultaneous stereo/mono bass applications, the crossover selection switch should be set to FLAT. If the amplifier is driving your subwoofers, set the switch to LPF, and for mid-bass/midrange output, set to HPF. • The crossover frequency control needs to be adjusted to suit your particular system. For subwoofer applications, try to keep the setting low enough to prevent the 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 midbass/ 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. 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 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. • The same procedure should be used for adjusting the amplifier when the on-board crossover is set to LPF or HPF, but you will also have to take into consideration...
