5.1 stýringar yfirview

  • GAIN (Volume) Control: Stillir heildarútgangsstyrk bassans. Byrjaðu á lágum stillingum og aukið þá smám saman þar til bassinn blandast fullkomlega við aðalhátalarana.
  • 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-rofi (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:
    • Kveikt: Basshátalarinn er stöðugt kveiktur.
    • SJÁLFvirkt: Basshljóðneminn kveikir sjálfkrafa á sér þegar hljóðmerki greinist og fer í biðstöðu eftir að hafa ekki verið notaður í smá tíma.
    • SLÖKKT: Basshljóðneminn er slökktur.

6. Viðhald

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

  • Loftræsting: Gakktu reglulega úr skugga um að loftræstiop séu laus við ryk og rusl til að koma í veg fyrir ofhitnun.
  • Geymsla: Ef þú geymir bassahátalarann ​​í langan tíma skaltu aftengja hann frá rafmagninu og geyma hann á köldum, þurrum stað, helst í upprunalegum umbúðum.
