Should i always use LFE? (1 Viewer)

[Ryan-Stone]

I was wondering if i should use LFE for only DD and DTS or can i use it for every thing(pro logic,DD,DTS). The instuction book says to use LFE for a digital signal and use "normal" for analog signals. Would it sound bad to use LFE for analog and digital?

LFE only exists on DD and DTS signals; it's the '.1' in '5.1' signals; ie, 5 discrete channels plus a Low Frequency Effects channel.

Most receivers switch to "normal" for non 5.1 signals; they use the receiver's cross over circuit to send sounds below a pre-set frequency to your subwoofer. Note that this will also occur for digital signals without a dedicated LFE channel (just because a signal is encoded in DD or DTS doesn't mean it has 5.1 channels)
