Anleitung Zusammenfassung
Warning Thoroughly investigate the layout of your vehicle before drilling or cutting any holes. Take extra precautions when working near tanks, lines, hydraulic lines, and electrical wiring. Don’t mount this system so that the wire connections are unprotected or are subject to pinching or damage from nearby objects. The +12 volt DC power wire must be fused at the battery positive (+) terminal connection. Before making or breaking power connections at this system’s power terminals, disconnect the +12V wire at the battery end. Make sure that your stereo and other audio equipment is turned off while connecting the input jacks and speaker terminals of your amplifier. If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the system. Using a fuse of a different type or rating may result in damage to this system, which isn’t covered by the warranty. 12 Insignia NS-A1200 Car Amplifier Connecting the speakers Single-amplifier system Front view Rear view To inputs of satellite amplifier system From outputs of source device Woofer Ground To remote turn-on from source device Capacitor Distribution block Battery In-line fuse holder 13 Insignia NS-A1200 Car Amplifier Bridging two amplifiers Using your amplifier Turning on the amplifier The amplifier automatically turns on a few seconds after you turn your vehicle’s ignition switch to ACC or ON or turn on your sound system, depending upon how you wired the system. The POWER indicator on the top of the amplifier turns on when the amplifier is on. Note Your amplifier requires 90 amps or more of power from your vehicle’s battery during operation. To protect your battery from discharging to the point that you cannot start your vehicle, do not operate the amplifier unless your vehicle is running.

Insignia NS-A1200 Car Amplifier Adjusting the audio level by ear For best performance, you must match the amplifier’s input sensitivity to your source’s maximum output level (also called “gain matching”). The LEVEL (gain) control located on the side of the amplifier is designed to do this. It is not a volume control. It adjusts the incoming signal level so that the source device and the amplifier reach maximum output at the same time. This ensures that maximum system volume is achieved with minimal distortion. Warning High-powered audio systems in a vehicle are capable of generating “live concert” levels of sound pressure. Continued exposure to excessively high volume sound levels may cause hearing loss or damage. Operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to hear external sounds such as horns, warning signals, or emergency vehicles, which could create a traffic hazard. To adjust the audio level: 1 Turn the LEVEL (gain) control fully counterclockwise to MIN. 2 Play full-frequency music that has continuously high levels (FM pop music is a good choice). 3 Turn up the source device’s volume control until just before you hear the source device’s distortion, or at 90% of full output (whichever comes first). 4 Slowly turn the LEVEL (gain) control clockwise until just before you hear amplifier or speaker distortion, or until you reach a maximum comfortable listening level (whichever comes first). 5 Turn the source device’s volume control back down to a comfortable listening level. Adjusting bass boost +18 dB @45 Hz Insignia NS-A1200 Car Amplifier The BASS BOOST control raises the amplifier output up to 18 dB at frequencies tightly centered around 45 Hz. This “bump” can have a dramatic effect on the bass system’s apparent volume. Use caution when adjusting this control, as subwoofer damage may result if the subwoofer begins to distort. When you exceed the subwoofer’s capabilities, the distortion will be obvious. To adjust bass boost: 1 Rotate the BASS BOOST control counter-clockwise until it points at 0. Use a screwdriver to adjust the BASS BOOST control on the amplifier, or adjust the remote BASS BOOST control by hand. Caution Adjusting the bass boost should be done with caution, so that the woofer cone throw’s maximum excursion is not reached. Adjust to the woofer’s best performance level (best bass performance where no distortion is present), then reduce the bass boost slightly. 2 Play some music, and adjust the source device’s volume and the amplifier’s LEVEL (gain) control to a comfortable listening level. 3 Slowly rotate the BASS BOOST control clockwise until it sounds the way you want. Troubleshooting Symptom Cause Solution No sound. If the PWR LED is off, fuses may be blown, remote lead may be disconnected, source leads may be disconnected, gain control may be set too high or low, or source device’s volume may be set too low. Check fuses in amplifier and on power lead...
