Informazioni sulla sicurezza

Per evitare lesioni o danni all'apparecchiatura, osservare sempre le seguenti precauzioni di sicurezza:

• Installazione professionale consigliata: L'installazione di apparecchiature audio per auto può essere complessa. In caso di dubbi su qualsiasi fase del processo di installazione, rivolgersi a un professionista qualificato.
• Scollegare la batteria: Prima di iniziare qualsiasi lavoro elettrico, scollegare il terminale negativo della batteria del veicolo per evitare cortocircuiti e danni.

Configurazione e installazione

This section outlines the general steps for setting up your GZRB 250BPX subwoofer. Specific wiring diagrams for your amplifier should be consulted in conjunction with these instructions.

Disimballaggio

Carefully remove the subwoofer from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is present, contact your dealer immediately.

Posizionamento

The GZRB 250BPX is a bandpass enclosure, which typically performs well in the trunk or cargo area of a vehicle. Experiment with different orientations and positions to find the optimal sound for your vehicle's acoustics. Ensure the enclosure is not obstructing any safety features or vehicle controls.

Collegamenti elettrici

The subwoofer features a 50 mm 2 x 2 Ohm voice coil. Proper impedance matching with your amplifier is crucial for optimal performance and to prevent damage. Refer to your amplifier's manual for recommended wiring configurations (e.g., series or parallel) to achieve the desired impedance (e.g., 1 Ohm, 2 Ohm, or 4 Ohm).

1. Cablaggio di alimentazione: Collegare il amplifier's power input to the vehicle's battery using an appropriately gauged power cable, fused close to the battery.
2. Cablaggio di terra: Collegare il ampil terminale di terra del generatore a una superficie metallica pulita e non verniciata del telaio del veicolo.
3. Accensione remota: Collegare il amplifier's remote turn-on terminal to your head unit's remote output.
4. Ingresso segnale: Connect the RCA outputs from your head unit or line output converter to the ampingressi RCA del lifier.
5. Collegamento subwoofer: Connect the speaker output terminals of your amplifier to the input terminals on the GZRB 250BPX enclosure. Ensure correct polarity (+ to + and - to -).

Illuminazione a LED

The GZRB 250BPX features switchable LED illumination between white and blue. Consult the specific wiring or switch on the enclosure for controlling this feature. Typically, this will involve a separate power connection or a switch on the enclosure itself.

Istruzioni per l'uso

Once the subwoofer is installed and wired correctly, follow these steps for initial operation:

1. Accensione iniziale: Reconnect the vehicle's negative battery terminal. Turn on your head unit. The amplifier and subwoofer should power on.
2. Impostazione del guadagno: Inizia con il amplifier's gain control at its minimum setting. Play a familiar piece of music with strong bass. Slowly increase the gain until you hear distortion, then back off slightly. This ensures the amplifier non sovraccarica il subwoofer.
3. Impostazioni crossover: Utilizzare il filtro passa-basso (LPF) sul tuo amplifier or head unit to send only low frequencies to the subwoofer. A common starting point is 80-100 Hz. Adjust this setting to blend seamlessly with your vehicle's main speakers.
4. Controllo di fase: Alcuni amplifiers have a phase switch (0° or 180°). Experiment with both settings to determine which provides the most impactful and coherent bass response in your listening position.
5. Aumento dei bassi: Utilizzare l'amplificazione dei bassi con parsimonia, se non del tutto. Un'amplificazione eccessiva dei bassi può causare distorsioni e potenziali danni al subwoofer.

Allow the subwoofer to break in for several hours of normal use before playing at maximum volume. This allows the suspension components to loosen up and perform optimally.

Manutenzione

The Ground Zero GZRB 250BPX subwoofer requires minimal maintenance. Follow these guidelines to ensure its longevity:

• Pulizia: Use a soft, dry cloth to wipe down the enclosure and visible surfaces. Avoid using harsh chemicals or abrasive cleaners.
• Ispezione: Controllare periodicamente tutti i collegamenti elettrici per accertarsi che siano saldi e privi di corrosione.
• Condizioni ambientali: Protect the subwoofer from direct sunlight, extreme heat, and moisture.
• Montaggio sicuro: Regularly check that the enclosure remains securely mounted in your vehicle.
