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.

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.

- 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.
