揚聲器擺放
建議
• 將揚聲器放於金屬櫃之外並遠離金屬櫃、其他音訊/視訊元件和直接熱源。
• 將揚聲器放到電視正下方（最佳）或正上方，使格柵朝向房間。
• 將揚聲器放在橡膠底座上並置於穩定的水平表面。為保證適當支撐，兩個支腳都
必須靠在表面上。振動會導致揚聲器移動，在光滑表面（大理石、玻璃或高度拋
光的木材）上，這種情況特別突出。
• 如果將揚聲器放在架子或電視架上，一定要使揚聲器前側儘量靠近架子或電視架
前沿以獲得最佳音質。
• 使揚聲器的後側與任何其他表面保持至少 1c
m
的距離。堵塞這一側的連接埠會影
響音質。
• 確保附近有交流（市電）插座。
• 為了避免干擾，應使其他無線設備遠離揚聲器 0.3 – 0.9 m。
• 為了獲得最佳音質，請勿將揚聲器放置於封閉式機櫃或斜放在角落。
• 請勿在揚聲器上放置任何物品。
小心： 在使用時請勿將揚聲器躺放、側放、倒放。
