5. Impostazione
Posizionamento
The recommended placement for the DALI SUB E-12F is on the floor, near a wall or in a corner. Experiment with different positions to find the best bass response for your room. Corner placement often provides the most bass output, while placement along a wall can offer a more balanced sound.
Connessioni
Before making any connections, ensure the subwoofer and all connected audio equipment are turned off and unplugged from the power outlet.
- Collegamento elettrico: Connect the supplied power cord to the AC INLET on the subwoofer's rear panel and then to a suitable wall outlet.
- Connessione audio:
- For AV Receivers with LFE Output: Connect a single RCA cable from the LFE output of your AV receiver to the LFE INPUT on the subwoofer.
- For Stereo Amplifiers/Pre-amplificatori: Connect RCA cables from the pre-out or line-out of your amplificatore/pre-amplifier to the LINE INPUT (Left/Right) on the subwoofer.
6. Istruzioni per l'uso
- Accensione: After making all connections, flip the main POWER switch to the 'ON' position. If the POWER MODE switch is set to 'AUTO', the subwoofer will automatically turn on when an audio signal is detected. If set to 'ON', it will remain on.
- Regolazione del volume: Start with the VOLUME knob at a low setting (e.g., 9 o'clock position). Play some audio and gradually increase the volume until the bass blends seamlessly with your main speakers.
- Frequenza di crossover: Adjust the CROSSOVER knob to set the frequency at which the subwoofer takes over from your main speakers. A good starting point is typically between 60Hz and 80Hz, depending on the low-frequency capabilities of your main speakers.
- Regolazione della fase: Use the PHASE switch (0° or 180°) to ensure the subwoofer's output is in phase with your main speakers. Listen for the most impactful and coherent bass response. You may need to experiment with both settings.
- Modalità audio: The subwoofer supports various sound modes, including Standard Mode, Live Sound Mode, and Extra Bass Mode, which can be influenced by the source signal or system settings.
7. Manutenzione
To keep your DALI SUB E-12F in optimal condition:
- Pulizia: Per pulire il mobile, utilizzare un panno morbido e asciutto. Non utilizzare detergenti abrasivi, cere o solventi.
- Polvere: Regularly dust the grille and cabinet to prevent buildup.
- Ventilazione: Assicurarsi che le aperture di ventilazione siano libere da ostruzioni per evitare il surriscaldamento.
- Evitare la luce solare diretta/il calore: Do not place the subwoofer in direct sunlight or near heat sources.
8. Risoluzione Dei Problemi
If you encounter issues with your subwoofer, try the following:
- Nessun suono: Check all cable connections (power and audio). Ensure the subwoofer is powered on and the POWER MODE switch is not in 'OFF'. Verify the source device is playing audio.
- Bassi deboli: Adjust the VOLUME and CROSSOVER knobs. Experiment with the PHASE switch. Try different placement positions.
- Suono distorto: Reduce the VOLUME. Check if the source audio is distorted. Ensure all connections are secure.
- Rumore di ronzio: Check for ground loops. Try plugging the subwoofer into a different electrical outlet. Ensure audio cables are not running parallel to power cables.

10. Suggerimenti per l'utente
- Acustica della stanza: Subwoofer performance is highly dependent on room acoustics. Experiment with placement and settings to achieve the best sound in your listening environment.
- Calibrazione: If your AV receiver has an automatic room calibration system (e.g., Audyssey, MCACC), run it after connecting the subwoofer. This will help optimize the subwoofer's settings for your room.
- Integrazione: The goal is to integrate the subwoofer seamlessly with your main speakers, not to overpower them. The bass should sound like it's coming from the entire soundstage, not just the subwoofer's location.
