5. Amplifier Layout and Connections

Biasakan diri anda dengan amplifier's layout and connection terminals before proceeding with installation.

Rajah 5.1: Panel belakang view of the ESX QL750.1 amplifier, highlighting power input, signal inputs (RCA and high-level), output, and various control knobs.

5.1. Power Input Terminals

• GND (Tanah): Sambungkan pada permukaan logam casis kenderaan yang bersih dan tidak dicat.
• REM (Jauh): Sambungkan ke output hidup jauh unit kepala anda atau sumber 24V yang telah dihidupkan.
• +24V (Kuasa): Connect directly to the positive terminal of the vehicle's 24V battery via an appropriate fuse holder.

5.2. Signal Input Terminals

• INPUT (RCA): Low-level RCA inputs for connecting to your head unit's RCA pre-outs.
• INPUT ARAS TINGGI: For connecting to your head unit's speaker outputs if RCA pre-outs are not available.

5.3. Terminal Keluaran

• KELUARAN (RCA): Line output for connecting to another amplebih hidup dalam pelbagaiamppersediaan penguat.
• OUTPUT SPEAKER: Connect your subwoofer(s) to these terminals. Observe correct polarity.

5.4. Control Knobs and Switches

• LEVEL INPUT (MIN/MAX): Melaraskan kepekaan input agar sepadan dengan output unit kepala anda.
• SUB SONIC (10Hz-40Hz): Filters out ultra-low frequencies below the audible range, protecting your subwoofer.
• LOW PASS (40Hz-150Hz): Sets the upper frequency limit for the subwoofer.
• BASS BOOST (0dB-18dB): Increases bass output at 40Hz. Use sparingly to avoid distortion.
• PHASE SHIFT (0°-180°): Adjusts the phase of the subwoofer output to match other speakers in the system.
• AUTO TURN-ON (DC/VOX/OFF): Memilih amplifier's turn-on method when using high-level input.
  • DC: Detects DC offset from the head unit's speaker output.
  • VOX: Detects audio signal from the head unit's speaker output.
  • MATI: Disables auto turn-on; requires REM connection.

6. Persediaan dan Pemasangan

Pemasangan yang betul adalah penting untuk prestasi dan keselamatan peranti anda amplifier. Follow these steps carefully.

6.1. Memasang Amplebih hidup

• Pilih lokasi yang kering, mempunyai pengudaraan yang baik, jauh daripada cahaya matahari langsung dan sumber haba.
• Pastikan terdapat ruang yang mencukupi di sekeliling amplifier for airflow, especially around the cooling fins.
• Gunakan skru pelekap yang disediakan untuk memasangnya amplifier firmly to a solid surface in your vehicle.

6.2. Power Wiring (24V System)

1. Putuskan Sambungan Bateri: Before making any power connections, disconnect the negative terminal of your vehicle's 24V battery.
2. Power Cable (+24V): Run a heavy-gauge power cable (e.g., 8 AWG or thicker, depending on cable length and power requirements) from the positive terminal of the 24V battery to the amplifier's "+24V" terminal. Install an appropriate fuse holder (e.g., 40A-60A, refer to ampspesifikasi pengisi kuasa untuk penarafan tepat) dalam lingkungan 18 inci (45 cm) dari bateri.
3. Ground Cable (GND): Run a heavy-gauge ground cable (same gauge as power cable) from the amplifier's "GND" terminal to a clean, unpainted metal part of the vehicle chassis. Ensure a good electrical connection.
4. Remote Turn-On Cable (REM): Run a smaller gauge wire (e.g., 18 AWG) from your head unit's remote turn-on output (usually blue/white wire) to the amplifier's "REM" terminal. If using high-level input with auto turn-on, this connection may not be necessary.

6.3. Signal Input Connection

• Input RCA: Connect RCA cables from your head unit's subwoofer pre-out (or full-range pre-out if no dedicated sub-out) to the amplifier's "INPUT" RCA jacks.
• Input Tahap Tinggi: If your head unit does not have RCA outputs, connect the speaker wires from your head unit to the amplifier's "HIGH LEVEL INPUT" connector. Ensure correct polarity. Set the "AUTO TURN-ON" switch to "DC" or "VOX" as appropriate.

6.4. Sambungan Output Speaker

• Sambungkan subwoofer anda ke terminal "SPEAKER OUTPUT". Pastikan kekutuban yang betul (+ ke + dan - ke -).
• Verify the impedance of your subwoofer(s) to ensure it is within the amplifier's supported range (e.g., 1 Ohm stable).

6.5. Permulaan Kuasa

• Double-check all connections for correctness and security.
• Sambung semula bateri kenderaan.
• Hidupkan unit kepala anda. amplifier should power on (indicated by a power LED).

7. Arahan Operasi dan Pelarasan

Once installed, fine-tune the amptetapan pencahayaan untuk kualiti bunyi yang optimum.

7.1. Gain (Level Input) Adjustment

• Set your head unit's volume to about 75% of its maximum.
• Play a dynamic piece of music.
• Perlahan-lahan tingkatkan amplifier's "LEVEL INPUT" gain control until you hear distortion, then back it off slightly. This matches the amplifier's input sensitivity to your head unit's output.

7.2. Crossover Settings (Subsonic & Low Pass)

• LALUAN RENDAH (LPF): Adjust this control to set the upper frequency limit for your subwoofer. A common starting point is 80-100 Hz, but this depends on your subwoofer and other speakers.
• SUB SONIC: Set this filter just below the lowest frequency your subwoofer can safely reproduce, or just below the tuning frequency of your ported enclosure. This protects the subwoofer from over-excursion. A common setting is 20-30 Hz.

7.3. Peningkatan Bass

• The "BASS BOOST" control provides an increase in bass output at 40 Hz. Use this feature cautiously. Excessive bass boost can lead to distortion and potential damage to your subwoofer. Start at 0dB and increase gradually if desired.

7.4. Anjakan Fasa

• The "PHASE SHIFT" control (0°-180°) helps to align the subwoofer's output with the rest of your vehicle's speakers. Experiment with this setting while listening from your normal seating position. The correct setting will result in the most impactful and seamless bass response.

7.5. Remote Bass Control

• Connect the provided remote bass control unit to the amplifier. This allows for convenient adjustment of the subwoofer's output level from the driver's seat.
