User manual DEI 1100D5

[. . . ] models 1100d5 2 © 2002 Directed Electronics, Inc 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. [. . . ] It is the summed stereo output of the one through four channel inputs of the amplifier. RCA Sync Out Jack - This RCA jack sends a synced, or in-phase, gain matched signal to a 600d slave amplifier when connected in the Parallel Synced Gain combination. RCA Bridge Output Jack - This output sends an out-of-phase signal to a 600d slave amplifier when connected in the External Synced Bridged combination. Status LEDs - The Power LED will light GREEN to indicate the amplifier is on and operating normally. The GREEN LED will turn off and the Protection LED will light RED when the amplifier has shut itself down due to speaker short circuit, DC offset or overheating. Remote Sub Level Control - Controls the subwoofer amplifier gain controls from a remote location for ease of adjustment during listening. Warning: DO NOT connect a level control knob from other manufacturers to the Remote Sub Level Control of any Directed amplifier. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged.

Power Fuses - These fuses protect the amplifier against internal electrical damage and are meant to protect the amplifier only. (+) 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. 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 on lead is not available, Remote Power Adapter (P/N #55000) can be used to supply a remote turn on signal. 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. 5.

The control panel cover must be removed to gain access to the gain and filter controls. Four Allen-head screws hold the control panel cover to the amplifier top panel, one at each corner. They can be removed with the wrench supplied in the hardware pack. © 2002 Directed Electronics, Inc 11 SPEAKER WIRING DIAGRAMS Five channel operation (top view) Three channel operation (top view) 12 © 2002 Directed Electronics, Inc COMBINED AMPLIFIERS The Viper 1100d5 channel five subwoofer section can be combined with a 600d in a master/slave combination for increased power and accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations. NOTE: The Directed 1100d5 is always the master amplifier in these combinations. External Synced Bridged The External Synced Bridged combination includes a master amplifier and a slave amplifier. In this master/slave combination the master amplifier's pre-amp controls remain active and the slave amplifier's pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. [. . . ] 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. [. . . ]
