GROUND CONNECTION Connect the amplifiers Ground (GND) terminal to a solid point on the vehicles metal chassis, as close to the amplifier as possible. Refe

POWER CONNECTION Connect a wire (see chart at right for appropriate gauge) directly to the vehicles positive battery terminal, and install an appro

Be sure to use appropriate grommets whenever routing wires through the firewall or other sheet metal. Fail

When you are done routing and connecting this wire to the battery and to the amplifier, you may install the fuse at the battery. The fuse value should be selected based on total amplifier-current draw; se

If your installation differs markedly, you will need to adjust the wire gauge accordingly. SPEAKER CONNECTIONS Refer to the application guides on the pages that

13、follow. Speaker connections should be made using a minimum of 16-gauge wire. NOTE:When using the low-level or high-level inputs, the AUX outputs can be used to pass a full-range line-level signal to another amplifier. POWERCONNECTIONS Figure 1.Terminal-connection end plate.

Either set of (+/) terminals may be used when connecting woofers. To the right are two application diagrams to help plan your sub

15、woofer system installation. Figures 3 and 4 show how to configure the Reference subwoofer amplifiers NOTE: For simplicity, Figures 3 and 4 do not show power, remote and input connections.

SETTING INPUT SENSITIVITY 1. Initially turn the INPUT LEVEL control(s) to minimum (counterclockwise). 2. Reconnect the () negative

17、lead to the vehi- cles battery. Apply power to the audio system and play a dynamic music track. 3. 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

18、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 remote connection from the source unit. Also refer to “Troubleshooting” on the page 7. INSTALLATION ANDSE

19、TUP REMOTE LEVEL CONTROL (OPTIONAL) All three Reference subwoofer amplifiers and the 5760a amplifier have inputs for an optional remote level control (100rc). This will allow the subwoofer level to be adjusted from the listening position. Connect the optional remote level control using the RJ-11 jac

20、k on the side of the amplifier. Install the control module in the front of the vehicle within easy reach of the driver. Both the underside of the dash and the center console are suitable locations. Refer to the mounting instructions accompanying the 100rc. AUX OUTPUT Reference amplifiers are equippe

21、d with full-range outputs that can be used to connect additional amplifiers. NOTE:When using the low- or high-level inputs, the AUX outputs can be used to pass a full-range line-level signal to another amplifier.

22、amplifier is being overdriven, and your speakers may be in danger. This should blink only on musical peaks, and not be on constantly. Power: Indicates the amplifier is on. Protection: Refer to “Troubleshooting” for specific indications. Figure 15. LED status. SETTING DBO The Dynamic Bass Optimizer (

23、DBO) is used to enhance low-frequency reproduction in a vehicle. Conventional bass-boost circuits only increase bass at a fixed frequency, and cause the amplifier to consume considerable power. The DBO allows you to adjust the frequency (20Hz 80Hz) as well as the boost level (up to 12dB; see Figure

24、14), allowing you to fine-tune the bass in your system to optimize performance. For sealed enclosures, the DBO can be used to enhance the lower bass region of sealed enclosures. For bigger/fuller bass, adjust the HP FREQ between 35Hz and 45Hz; adjust the BOOST control according to your preference. F

25、or tighter-sounding bass, adjust the HP FREQ between 45Hz and 55Hz; adjust the BOOST control according to your preference. For vented enclosures, the DBO should be used as a subsonic filter to reduce overexcursion of the woofers. Set the HP FREQ control 10Hz below the tuning frequency of the enclosu

26、re (e.g., 25Hz for a box tuning of 35Hz); adjust the BOOST control to taste. This will conserve amplifier power typically wasted on frequencies below the tuned frequency of the enclosure. For infinite-baffle applications, set the HP FREQ to the speakers Fs value (reducing overexcursion of the woofer

27、); adjust the Boost control to taste. Figure 14. Frequency-response curves show typical DBO control ranges. INSTALLATION ANDSETUP(CONT.) -9 -6 -3 0 -12 2080Freq.
