Initially turn the INPUT LEVEL control(s) to the minimum (counterclockwise) position. 2. On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL contr

16、ol(s) toward three oclock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard. NOTE: After the source unit is on, blue LEDs (on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remo

17、te connection from the source unit. Also refer to “Troubleshooting.” REMOTE LEVEL CONTROL The 1300a, 1600a and 5350a include a remote level control. This will allow the subwoofer level to be adjusted from the listening position. Connect the remote level control using the RJ11 jack on the side of the

18、 amplifier. Install the control module in the front of the vehicle within easy reach of the driver. Both the under- side of the dash and the center console are suitable locations. UNDER-DASH MOUNTING Select a mounting location that allows easy access to the control while driving. Using the REMOTE LE

19、VEL control as a template, mark and drill holes in the mounting surface. Attach the REMOTE LEVEL control using the mounting screws provided (Figure 11). Figure 11. Under-dash mounting of the REMOTE LEVEL control. Refer to the illustrations on the previous pages for control location. Reconnect the ()

20、 negative lead to the vehicles battery. Apply power to the audio system and play a dynamic music track. SETTING THE CROSSOVER(S) Determine your system plans and set the crossover-mode switch accordingly. If your system design does not include a subwoofer, set the crossover mode to FULL and skip to “

21、Setting Input Sensitivity.” If your system includes a subwoofer, set the crossover mode to HP (high-pass) for your full-range speakers. Adjust the crossover frequency to limit bass, and provide increased system volume with less distortion. Mode Switch: Full: Allows a full-range signal through to the

22、 speakers; can be used with larger full-range speakers such as 6 x 9s. HP: Allows a high-pass signal through to the speakers; should be used with most loudspeakers (can protect your full-range speakers from being overdriven with low frequencies, one cause of speaker damage). LP: Allows only bass to

23、pass through to the speakers; should be selected when powering subwoofers. High-Pass Filters: Initially set the crossover- frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possibl

24、e. Low-Pass Filters: For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer. If using the 475a to drive a subwoofer(s), set the crossover mode to LP (low-pass) on the channels connected to the subwoofer. NOTE: The 1300a, 1600a and the subwoofer ou

25、tput of the 5350a are low-pass only and do not have a crossover-mode switch. INSTALLATION ANDSETUP Route the cable behind the dash or other interior panels and under the carpet. Do not route the cable outside the vehicle. Connect the RJ11 cable between the RJ11 receptacle on the amp and the receptac

26、le on the REMOTE LEVEL control (Figure 12). Figure 12. REMOTE LEVEL control electrical connection. SETTING THE BASS BOOST The Bass Boost control will allow you to enhance the bass output of your system at 50Hz up to 6dB. AUX OUTPUT Reference amplifiers (except 5350a) are equipped with full-range out

27、puts that can be used to connect additional amplifiers. STATUS LEDs Power: Indicates the amplifier is on. Protection: Refer to “Troubleshooting” for specific indications. Figure 13. LED status. TROUBLESHOOTING PROBLEM: No audio (POWER LED is off). CAUSE and SOLUTION: No voltage at BATT+ and/or REM t

28、erminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM. PROBLEM: No audio (PROTECT LED glows red). CAUSE and SOLUTION: DC voltage on amplifier output. Amplifier may need service; see enclosed warranty card for service information. PROBLEM: No audio (PROTECT LED glow

29、s red). CAUSE and SOLUTION: Amplifier is overheated. Make sure amplifier cooling is not blocked at mounting location; verify that speaker-system impedance is within specified limits. PROBLEM: No audio (PROTECT LED glows red). CAUSE and SOLUTION: Voltage less than 9V on BATT+ connection. Check vehicl

30、e charging system. PROBLEM: No audio (PROTECT LED glows red). CAUSE and SOLUTION: Voltage greater than 16V or less than 8.5V on BATT+ connection. Check vehicle charging system. PROBLEM: Distorted audio. CAUSE and SOLUTION: Input sensitivity is not set properly, or amplifier or source unit is defecti

31、ve. Check INPUT LEVEL setting, or check speaker wires for shorts or grounds. PROBLEM: Distorted audio (PROTECT LED glows intermittently). CAUSE and SOLUTION: Short circuit in speaker or wire. Remove speaker leads one at a time to locate shorted speaker or wire, then repair. PROBLEM: Music lacks “pun

32、ch.” CAUSE and SOLUTION: Speakers are not connected properly.
