正在RIP手上一張CD「Erich Kunzel and the cincinnati Pops Top 20」,突然注意到CD盒背面有一段警告訊息:
CAUTION:Digital Sound Effects of high levels with infrasonic frequenceies to 5Hz,Please establish safe playback levels before playing tracks.
Excessive playback levels could result in damage to equipment.
英文不太好,上面這段意思是CD當中的歌曲的低音會低到 5Hz,請建立安全的播放環境?(頻率響應沒到 5Hz 的設備不能播放這張CD? )
然後重複播放可能會損壞設備?啊咧∼真的會這樣嗎?
