重低音喇叭後面板控制鈕和連接
1) 電源模式:
切換至「Auto」(自動)位置後,重低音喇叭會進入待命模式。當偵測
到音訊訊號後,重低音喇叭會自動開啟,並在大約 10 分鐘內未偵測到任
何音訊訊號後返回到待命模式。將此開關設定到「On」(開啟)會對重
低音喇叭保持供電,直到電源開關被設定到「Off」(關閉)為止。
2) 開啟/待命 LED
當電源開關處於「On」(開啟)位置時,此 LED 指示重低音喇叭處於開
啟或待命狀態。
LED 發藍光時,重低音喇叭已開啟。
LED 發紅光時,重低音喇叭處於待命模式。
3) 相位開關:
此開關決定重低音喇叭轉換器的活塞式動作是否以與主喇叭同相的方式
移入移出。若重低音喇叭在播放時與主喇叭不同相,那麼主喇叭發出的
聲波可能部分地抵消重低音喇叭發出的聲波,從而降低低音效能和聲音
的震撼力。這種現象部分地取決於所有喇叭相對於聆聽位置的放置以及
它們在房間內彼此的相對位置。
4) 分頻控制鈕:
此控制鈕決定重低音喇叭再現聲音時所處的最高頻率。分頻控制鈕設定
得越高,重低音喇叭工作的頻率也會越高,並且其低音與喇叭的低音
「重疊」得越多。對於各種不同房間和重低音喇叭位置,此調節都有助
於重低音喇叭和其他喇叭之間達到低音頻率的平穩過渡。
5) 音量:
此控制鈕用於調節重低音喇叭的音量。順時針轉動旋鈕可增大音量;逆
時針轉動旋鈕可減小音量。
6) 重低音喇叭(LFE 輸入):
將重低音喇叭連接到接收器/處理器的專用重低音喇叭/LFE 輸出端。
7) 電源開關:
將此開關設定到「On」(開啟)位置可開啟重低音喇叭。如果您 要外
出或是會停用重低音喇叭較長一段時間,請將此開關設定到「Off」(關
閉)位置以節省能源。
8) 電源輸入:
在完成並確認重低音喇叭的輸入連接後, 請將電源線插入帶電且不切換
的電源插座, 以實現重低音喇叭的正常工作。
請勿將電源線插入某些音訊元件上的附件插座。
