3.2. د تارونو نښلول
The HD900/5 utilizes removable power and speaker plugs for simplified wiring. Ensure all connections are secure and properly insulated.
- برېښنا او ځمکه: A 4-gauge power and ground lead is recommended. An external 60-amp in-line fuse is required on the power wire, located close to the battery.
- سیګنال داخلونه: د amplifier features differential-balanced inputs to minimize noise from the vehicle's electrical system. It accepts both preamp-level (RCA) and speaker-level inputs. A separate adapter may be required for speaker-level input.
- د سپیکر محصولات: Connect your speakers to the designated output terminals. The amplifier supports various impedance loads:
- Front/Rear Channels: 100 watts RMS x 4 at 4 ohms, or 75 watts RMS x 4 at 1.5-3 ohms. Can be bridged to 150 watts RMS x 2 at 3-6 ohms.
- Subwoofer Channel: 500 watts RMS x 1 at 1.5-4 ohms.
- ریموټ چالان: Connect the remote turn-on lead from your head unit to the ampد لایفیر ریموټ ان پټ.
۲. د چلولو Ampلايف
The HD900/5 offers various controls for fine-tuning your audio system's performance.
4.1. Crossover Adjustments
- متغیر لوړ پاس فلټر: Available on the front and rear channels (50-500 Hz, 12 or 24dB/octave). This filter allows you to remove low frequencies from your full-range speakers, improving clarity and protecting them from over-excursion.
- متغیر ټیټ پاس فلټر: Available on the subwoofer channel (50-500 Hz, 12 or 24dB/octave). This filter allows only low frequencies to pass to the subwoofer, ensuring it reproduces only the intended bass notes.
- سبسونیک فلټر: On the subwoofer channel (24 dB/octave at 30 Hz). This filter removes extremely low, inaudible frequencies that can waste amplifier power and potentially damage subwoofers.
4.2. Input Sensitivity (Gain)
Adjust the input sensitivity controls to match the output voltage of your head unit. This ensures the amplifier receives an optimal signal without clipping or distortion. Refer to the detailed instructions in the full JL Audio manual for proper gain setting procedures.
4.3. Optional Remote Level Control
An optional wired remote control can be connected to the amplifier for convenient adjustment of the subwoofer channel's level from the driver's seat.
5. ساتنه
