In Topic: Setting gains on XTi amps

Please do this with no speakers connected!  40 volts of 1kHz in a speaker will be, errr, anoying to hear!  ;)

If you need a subsonic filter (20 Hz high pass) then the XLS won't do it.  This is an entry-level amp.  There is no such thing as firmware updating on this amp either.

Amps don't blow speakers.  Sound operators do.

What Crown probably meant in their white paper is, if you use an underpowered amp, you will tend to overdrive it, so the speaker is now getting an higher *average* power level, even if the peaks are not higher (they can't, they are clipped).  And a marginal speaker is now at risk of overheating, then blowing.

Yes.  A two channels amp is just that : two amps in one box.  Hence each channel is operating independently of the other.  Different loads on each channel is OK.  It's done regularly actually!

This is doable and will work, but is not generally recommanded.  The 4 ohms load will receive more power than the 8 ohms load, which may be a good thing, or not, depending on the power rating of each speaker.

Try it anyway!
