4. Impostazione

4.1 Posizionamento del subwoofer

For optimal performance and bass response, it is recommended to place your Klipsch Sub-120 subwoofer in a corner of the room. Corner placement utilizes the room's acoustics to enhance bass output and provide a more immersive audio experience.

4.2 Connessioni

The Klipsch Sub-120 offers flexible connection options to integrate with almost any AV receiver or stereo system.

  • Ingresso LFE (effetti a bassa frequenza): For receivers with a dedicated subwoofer output (LFE or SUB OUT), connect a single RCA cable from the receiver's subwoofer output to the LFE input on the subwoofer. This is the recommended connection for home theater systems.
  • Line In (Stereo RCA Inputs): If your receiver does not have an LFE output, connect stereo RCA cables from your receiver's pre-out (left and right) to the corresponding Line In (L/R) inputs on the subwoofer.

4.3 Collegamento di alimentazione

Once audio connections are made, connect the provided power cord to the subwoofer's power input and then to a suitable wall outlet (100-240V, 50/60Hz 2A).

5. Utilizzo del subwoofer

The Klipsch Sub-120 features several controls on its rear panel to fine-tune its performance to your listening environment and preferences.

5.1 controlli oltreview

  • Controllo GAIN (volume): Regola il livello di uscita complessivo del subwoofer. Inizia con un'impostazione bassa e aumentala gradualmente fino a quando i bassi non si fondono perfettamente con gli altoparlanti principali.
  • Controllo PASSA-BASSO (Crossover): This knob sets the upper frequency limit for the subwoofer. Frequencies above this setting will not be reproduced by the subwoofer. Adjust this to match the low-frequency capabilities of your main speakers. A common starting point is 80Hz, but it can be adjusted between 40Hz and 120Hz.
  • Interruttore di FASE (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with both settings to find the one that provides the most impactful and coherent bass response in your listening position.
  • ON/AUTO/OFF Switch:
    • SOPRA: Il subwoofer rimane costantemente acceso.
    • AUTO: Il subwoofer si accende automaticamente quando viene rilevato un segnale audio e passa alla modalità standby dopo un periodo di inattività.
    • OFF: Il subwoofer è spento.

6. Manutenzione

To ensure the longevity and optimal performance of your Klipsch Sub-120 subwoofer, follow these simple maintenance guidelines:

  • Pulizia: Use a dry, soft cloth to wipe down the cabinet. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish.
  • Cura della griglia: The subwoofer features a removable grille. If cleaning is necessary, gently remove the grille and use a soft brush or vacuum cleaner with a brush attachment to remove dust.
  • Ventilazione: Controllare periodicamente che le aperture di ventilazione siano libere da polvere e detriti per evitare il surriscaldamento.
  • Magazzinaggio: If storing the subwoofer for an extended period, disconnect it from power and store it in a cool, dry place, preferably in its original packaging.
