  3. Kawalan Fader: Adjusts the balance between front and rear speakers.
  4. Penunjuk Tahap Kuasa: Multi-colored LEDs indicating output power levels.

4. Pemasangan dan Pendawaian

Before beginning installation, ensure the vehicle's battery is disconnected to prevent electrical shorts. This unit is designed for 12V DC negative ground systems.

4.1 Pemasangan

  • The 903G features a Half-DIN design, allowing for flexible installation in various vehicle dashboards or consoles.
  • Choose a location that provides adequate ventilation to dissipate heat, as the unit can become warm during operation.
  • Secure the unit using the provided mounting hardware.

4.2 Sambungan Pendawaian

Refer to the wiring diagram (if provided with your unit) for specific connections. The following describes general wiring principles:

  • Kuasa (wayar MERAH): Connect to a switched 12V DC power source (e.g., ignition wire) that turns on and off with the vehicle's ignition. Ensure this connection is fused.
  • Tanah (wayar HITAM): Connect securely to a clean, unpainted metal chassis point in the vehicle. A poor ground connection can lead to noise (ground loops).
  • Remote Turn-On (BLUE wire - if present): Connect to the remote output of your head unit. This will turn the equalizer on and off with your head unit.
  • Input Audio: Connect the speaker outputs from your head unit to the corresponding input terminals on the 903G. The unit supports 2 or 4 speaker hook-up.
  • Output pembesar suara: Connect your vehicle's speakers to the output terminals of the 903G. Ensure correct polarity (+ to + and - to -). The unit supports 4-8 Ohm output impedance.

Note: The unit's wiring may be angled downwards, which can reduce effective wire length. Plan your wire routing accordingly.

5. Operasi

Once installed and wired correctly, follow these steps to operate your Pyramid 903G:

  1. Hidupkan kuasa: Turn on your vehicle's ignition and your head unit. If wired correctly, the 903G should power on automatically or by using its Power ON/OFF switch. The multi-colored power level indicators will illuminate.
  2. Pemeriksaan Bunyi Awal: Start with all equalizer bands set to the center (flat) position. Play a familiar audio track.
  3. Adjust Fader Control: Use the Fader control to balance the sound between your front and rear speakers to your preference.
  4. Penyamaan: Adjust the 10 equalizer band sliders to fine-tune the audio frequencies. Each band allows for up to 12dB of boost or cut.
    • Lower frequencies (leftmost sliders) control bass.
    • Mid-range frequencies (middle sliders) control vocals and instruments.
    • Higher frequencies (rightmost sliders) control treble and clarity.
    Adjust gradually and listen for improvements in sound quality. Avoid extreme settings that can introduce distortion.
  5. Monitor Power Level Indicators: The multi-colored LEDs provide a visual indication of the amplifier's output. Avoid consistently high levels that may indicate clipping or distortion.

6. Penyelenggaraan

  • Pembersihan: Use a soft, dry cloth to clean the unit's exterior. Do not use harsh chemicals or abrasive cleaners.
  • Pengudaraan: Periodically check that the ventilation areas are not obstructed by dust or debris.
  • Sambungan: Ensure all wiring connections remain secure. Loose connections can lead to intermittent sound or noise.
