To the right are four application diagrams to help plan your subwoofer system installation. NOTE: For simplicity, Figures 3 an

Reference 1300a or 1600a amplifier with one woofer connection. 1600a Reference Series 4 SETTING INPUT SENSITIVITY 1. Initially turn the INPUT LEVEL control(s) t

13、o the minimum (counterclockwise) position. 2. On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(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: A

14、fter 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 remote connection from the source unit. Also refer to “Troubleshooting.” REMOTE LEVEL CONTROL The 1300a, 1600a and 5350a include a remote level control. This

15、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 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 consol

16、e are suitable locations. UNDER-DASH MOUNTING Select a mounting location that allows easy access to the control while driving. Using the REMOTE LEVEL control as a template, mark and drill holes in the mounting surface. Attach the REMOTE LEVEL control using the mounting screws provided (Figure 11). F

17、igure 11. Under-dash mounting of the REMOTE LEVEL control. Refer to the illustrations on the previous pages for control location. Reconnect the () 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 pla

18、ns 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 “Setting Input Sensitivity.” If your system includes a subwoofer, set the crossover mode to HP (high-pass) for your full-range speakers. Adjust the crossov

19、er frequency to limit bass, and provide increased system volume with less distortion. Mode Switch: Full: Allows a full-range signal through to the 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 lou

20、dspeakers (can protect your full-range speakers from being overdriven with low frequencies, one cause of speaker damage). LP: Allows only bass to pass through to the speakers; should be selected when powering subwoofers. High-Pass Filters: Initially set the crossover- frequency control midway. While

21、 listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible. Low-Pass Filters: For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer. If using the 475a to dri

22、ve 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 output 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 panel

23、s 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 receptacle on the REMOTE LEVEL control (Figure 12). Figure 12. REMOTE LEVEL control electrical connection. SETTING THE BASS BOOST The Bass Boost control will allo

24、w 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 outputs that can be used to connect additional amplifiers. STATUS LEDs Power: Indicates the amplifier is on. Protection: Refer to “Troubleshooting” for speci

25、fic indications. Figure 13. LED status. TROUBLESHOOTING PROBLEM: No audio (POWER LED is off). CAUSE and SOLUTION: No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM. PROBLEM: No audio (PROTECT LED glows red). CAUSE and SOLUTION: D

26、C voltage on amplifier output. Amplifier may need service; see enclosed warranty card for service information. PROBLEM: No audio (PROTECT LED glows red). CAUSE and SOLUTION: Amplifier is overheated. Make sure amplifier cooling is not blocked at mounting location; verify that speaker-system impedance

27、 is within specified limits. PROBLEM: No audio (PROTECT LED glows red). CAUSE and SOLUTION: Voltage less than 9V on BATT+ connection. Check vehicle 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 ve

28、hicle charging system. PROBLEM: Distorted audio. CAUSE and SOLUTION: Input sensitivity is not set properly, or amplifier or source unit is defective. Check INPUT LEVEL setting, or check speaker wires for shorts or grounds. PROBLEM: Distorted audio (PROTECT LED glows intermittently). CAUSE and SOLUTI

29、ON: Short circuit in speaker or wire. Remove speaker leads one at a time to locate shorted speaker or wire, then repair. PROBLEM: Music lacks “punch.” CAUSE and SOLUTION: Speakers are not connected properly. Check speaker connections for proper polarity. 1600a Reference Series 5 Item# Part Number De
