5.2 Sambungan Pendawaian
All wiring should be performed with the vehicle's battery disconnected. Use high-quality cables and connectors for optimal performance and safety.
5.2.1 Sambungan Kuasa dan Tanah
- Power (+BATT): Connect a main power cable (minimum 4 AWG recommended) from the amplifier's +BATT terminal to the vehicle's positive battery terminal. An appropriate fuse holder with an 80A fuse (not included) must be installed within 18 inches (45 cm) of the battery.
- Tanah (GND): Connect a ground cable of the same gauge as the power cable from the amplifier's GND terminal to a clean, solid, unpainted metal point on the vehicle chassis. Ensure a good electrical connection.
- Penghidupan Jauh (REM): Connect the REM terminal to the remote output of your head unit. This signal turns the amphidupkan dan matikan lampu dengan unit kepala anda.
5.2.2 Sambungan Input
The HDP5 offers both RCA (low-level) and High-Level inputs for compatibility with various head units.
Figure 2: Input panel of the Hertz HDP5 amplifier, showing RCA and high-level input terminals.
- RCA Inputs (PRE-IN A, PRE-IN B, SUB PRE-IN): Use high-quality RCA cables to connect the corresponding pre-out channels from your head unit to the ampinput RCA liifier.
- High-Level Inputs (HI-IN A, HI-IN B, SUB HI-IN): For head units without RCA outputs, connect the speaker wires directly from your head unit to these terminals. The amplifier features an auto turn-on function when using high-level inputs, which can be enabled via the 'HI-IN AUTO TURN-ON ON/OFF' switch.
- Input Mode Switch: Select the appropriate input mode (A, B, A+B SUB) based on your head unit's output configuration.
5.2.3 Sambungan Pembesar Suara
Sambungkan pembesar suara anda ke amplifier's output terminals. Ensure correct polarity (+ to + and - to -) for all speakers.
Figure 3: Output and power connection panel of the Hertz HDP5 amplifier, detailing speaker terminals and fuse location.
- Channels A & B: Connect your front and rear speakers to the L and R terminals for Channels A and B.
- Subwoofer (SUB): Connect your subwoofer to the L and R terminals for the SUB channel. The amplifier is designed to power a single subwoofer or multiple subwoofers wired to present an appropriate impedance.
6. Arahan Operasi
Once installed, the Hertz HDP5 amplifier requires proper adjustment of its controls to achieve optimal sound quality.
6.1 Kawalan dan Pelarasan
- Level Control (Gain): Adjusts the input sensitivity to match the output voltagunit kepala anda. Mulakan dengan penguatan minimum dan perlahan-lahan tingkatkannya sehingga kelantangan yang diingini dicapai tanpa herotan.
- Crossover Controls (HI-PASS, LO-PASS, BAND-PASS): These filters allow you to define the frequency range that each channel reproduces.
- HI-LULUS: Filters out frequencies below the set point, protecting smaller speakers from damaging low bass.
- LO-LULUS: Filters out frequencies above the set point, typically used for subwoofers to reproduce only bass frequencies.
- BAND-PASS: Allows a specific range of frequencies to pass, useful for mid-range speakers.
- Penapis Subsonik: Filters out extremely low, inaudible frequencies below the set point, protecting subwoofers from over-excursion and improving efficiency.
- Phase Control (SUB): Adjusts the phase of the subwoofer output (0° or 180°) to optimize bass integration with your front speakers and prevent cancellation.
- Bass Boost (SUB): Provides an adjustable low-frequency enhancement at a specific frequency, typically around 45-50 Hz. Use sparingly to avoid distortion.
- Turn-On Mode Switch: Selects between remote turn-on (REM) and auto turn-on (for high-level inputs).
