[. . . ] RCA Sync Out Jack - This RCA jack sends a synced, or in-phase, gain matched signal to a 750d slave amplifier when connected in the Parallel Synced Gain combination. (Refer to the Combined Amplifiers section of this guide. ) 5. RCA Bridge Output Jack - This output sends an out-of-phase signal to a 750d slave amplifier when connected in the External Synced Bridged combination. (Refer to the Combined Amplifiers section of this guide. ) 6. 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.

Sub Out Terminals - Connect subwoofers to these terminals. (Refer to the Speaker Wiring Diagrams section of this guide. ) 2. Speaker Out Terminals - Connect the speakers to these terminals. (Refer to the Speaker Wiring Diagrams section of this guide. ) 3. Power 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. (+) 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. DO NOT connect this terminal to constant (+) 12 volt. 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. [. . . ] 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. [. . . ]
