4. Suidhich

4.1 Suidheachadh 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 Ceanglaichean

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

  • Cuir a-steach LFE (Buaidhean Tricead Ìosal): 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.

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. A’ cleachdadh an fho-fhuaimeadair

5.1 Smachdan thairisview

  • GAIN (Volume) Control: Atharraichidh seo ìre toraidh iomlan an fho-fhuaimeadair. Tòisich le suidheachadh ìosal agus àrdaich mean air mhean gus am bi am beus a’ measgachadh gu rèidh leis na prìomh luchd-labhairt agad.
  • LOW-PASS (Crossover) Control: 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.
  • PHASE Switch (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:
    • AIR: Bidh an subwoofer a’ fuireach air a chumhachdachadh gu leantainneach.
    • AUTO: Bidh an subwoofer a’ tionndadh air gu fèin-ghluasadach nuair a lorgar comharra claisneachd agus a’ dol a-steach do mhodh feitheimh às deidh ùine de neo-ghnìomhachd.
    • OFF: Tha an subwoofer dheth.

6. Cumail suas

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

  • Glanadh: Use a dry, soft cloth to wipe down the cabinet. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish.
  • Cùram Grille: 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.
  • Fionnarachadh: Periodically check that the ventilation openings are clear of dust and debris to prevent overheating.
  • Stòradh: Ma tha thu a’ stòradh an subwoofer airson ùine mhòr, dì-cheangail e bhon chumhachd agus stòraich e ann an àite fionnar, tioram, mas fheàrr san phacaid thùsail aige.
