3. Persediaan dan Pemasangan
Proper installation is crucial for optimal performance and safety. Ensure you have all necessary tools and wiring before beginning.
3.1 Memasang Amplebih hidup
- Pilih lokasi pemasangan yang kering, mempunyai pengudaraan yang baik dan terlindung daripada cahaya matahari langsung atau haba yang berlebihan.
- Pastikan ruang yang mencukupi di sekeliling amppenguat untuk peredaran udara.
- Use the provided mounting hardware to secure the amplifier firmly to a solid surface.
3.2 Sambungan Pendawaian
Refer to the diagrams below for correct wiring connections. Always use high-quality cables.
Image 3.1: Rear panel of the Hertz DP 4.300 amplifier, showing power (GND, REM, +12V), fuse, and speaker output terminals.
Sambungan Kuasa:
- +12V (Kuasa): Connect to the positive terminal of the vehicle's battery via an appropriate fuse holder (not supplied) located within 18 inches of the battery.
- GND (Tanah): Connect to a clean, unpainted metal point on the vehicle chassis. Ensure a solid, low-resistance connection.
- REM (Penghidupan Jauh): Connect to the remote output of your head unit. This signal turns the amplifier on and off with the head unit.
Sambungan Pembesar Suara:
- Connect your speakers to the 'SPK OUT' terminals. Observe correct polarity (+/-) for each speaker.
- The amplifier supports 2Ω stable operation. Ensure your speaker impedance matches the ampkeupayaan liifier.
- For bridged mode operation, consult the specific wiring diagram in the full product manual for your speaker configuration.
Image 3.2: Front panel of the Hertz DP 4.300 amplifier, displaying RCA inputs (Mono In, Front In, Rear In, Pre Out), Speaker-In terminals, Auto Turn-On switch, Level controls, Filter Mode switches, and Frequency/Boost adjustments.
Sambungan Input:
- RCA Inputs (FRONT IN, REAR IN): Connect these to the corresponding RCA pre-outs from your head unit for low-level signal input.
- Speaker-In: For head units without RCA pre-outs, connect the speaker-level outputs directly to the 'SPK-IN' terminals. The amplifier features a Universal Speaker Simulator for compatibility.
- Auto Hidupkan: If using speaker-level inputs, the 'AUTO TURN ON' switch can be set to 'ON' to detect DC offset or audio signal for automatic amplifier turn-on, eliminating the need for a remote wire.
4. Arahan Operasi
Setelah dipasang, amplifier requires proper adjustment for optimal sound quality.
4.1 Adjusting Input Levels (Gain)
- Set the head unit volume to about 75% of its maximum.
- Play a dynamic piece of music.
- Slowly increase the 'LEVELS' control on the amplifier until you hear slight distortion, then back off slightly until the sound is clear.
- Avoid setting the gain too high, as this can lead to clipping and speaker damage.
4.2 Crossover Settings (Filter Mode)
- The 'FILTER MODE' switches allow you to select Full Range, High Pass (HI), or Low Pass (LO) filtering for each channel pair.
- PENUH: No filter applied.
- HI: Allows frequencies above the set point to pass. Useful for tweeters or full-range speakers.
- LO: Allows frequencies below the set point to pass. Useful for subwoofers.
- Adjust the 'FREQUENCY' knob to set the desired crossover point (e.g., 80 Hz for subwoofers, 100 Hz for mid-range speakers).
4.3 Peningkatan Bass
- The '50Hz BOOST' control allows you to increase bass output at 50 Hz.
- Use this feature sparingly and adjust carefully to avoid distortion or damage to speakers.
5. Penyelenggaraan
Penyelenggaraan yang kerap memastikan ketahanan dan prestasi peranti anda amplebih hidup.
- Pembersihan: Gunakan kain lembut dan kering untuk mengelapnya ampbahagian luar penapis. Jangan gunakan bahan kimia yang keras atau pembersih yang kasar.
- Pengudaraan: Memastikan bahawa ampSirip penyejuk lifier bebas daripada habuk dan serpihan untuk mengekalkan pelesapan haba yang betul.
- Sambungan: Periodically check all power, ground, and speaker connections to ensure they are secure and free from corrosion.
