Opsætning og installation

Choose a secure and dry location within your vehicle, such as under a seat, behind a seat, or in a storage compartment. Ensure the mounting surface is flat and stable. The aluminum casing provides durability, but avoid areas prone to excessive vibration or direct sunlight.

Ledningsforbindelser

The US08 subwoofer operates on a 24V power supply, suitable for trucks and buses. Use the provided power cable set for connections.

1. Power (24V+): Connect the positive wire from the subwoofer's power input to a constant 24V power source in your vehicle. It is recommended to connect directly to the battery with an inline fuse (not supplied, recommended 15A-20A) for protection.
2. Jord (GND): Connect the ground wire to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
3. Fjernbetjening (REM): Connect the remote turn-on wire to the remote output of your vehicle's head unit. This will turn the subwoofer on and off with your stereo.
4. Lydindgang (RCA): Connect the RCA audio cables from your head unit's pre-out (subwoofer or full-range) to the RCA input jacks on the US08. The audio output mode is Stereo.

Note: Ensure all connections are tight and properly insulated to prevent short circuits. Incorrect wiring can damage the unit or the vehicle's electrical system.

Første gang tændt

After completing all wiring connections, turn on your vehicle's ignition and head unit. The subwoofer should power on automatically via the remote wire connection.

Justering af indstillinger

The US08 typically features controls for gain (volume), low-pass filter (LPF), and phase. Refer to the specific controls on your unit for precise adjustments.

• Gain Control: Adjust this to match the output level of your head unit. Start with the gain at minimum and slowly increase it until the bass blends well with your main speakers without distortion.
• Lavpasfilter (LPF): This control sets the upper frequency limit for the subwoofer. Typically, set it between 80Hz and 120Hz to ensure the subwoofer only reproduces low frequencies.
• Faseomskifter: This switch (0° or 180°) helps to align the subwoofer's output with your main speakers. Experiment with both settings to find the one that provides the most impactful and coherent bass.

The maximum output power of the speakers is 24 Watts.

Opretholdelse

The Audio System US08 Subwoofer requires minimal maintenance. Follow these guidelines to ensure its longevity:

• Rensning: Use a soft, dry cloth to wipe down the exterior of the subwoofer. Do not use liquid cleaners or abrasive materials.
• Ventilation: Ensure that the cooling fins (if present) and surrounding area are free from obstructions to allow for proper heat dissipation.
• Forbindelser: Kontrollér regelmæssigt alle ledningsforbindelser for at sikre, at de forbliver fastgjorte og fri for korrosion.
• Miljø: Avoid exposing the subwoofer to extreme temperatures, direct sunlight, or excessive moisture.
