Hi! I just purchased a set of Bose Roommate II speakers to hook to my IIx's audio jack, and I was distressed to find that the IIx has a faint but clearly audible hiss coming from its audio port. It's not in the speakers, since when I disconnect them from the jack the hiss goes away. Any ideas on how to get rid of it? Thanks, --Mike

We have a set of Bose speakers here at work (on a IIcx), I'm convinced that they turn themselves OFF when there is no input from the audio jack. I have a set of tiny Sony speakers that do the same (they run on batteries)). I suspect that this is the case since the speakers have a built-in amp and no ON/OFF switch. Try hooking your IIx onto a GOOD set of headphones WITHOUT any amp, you should see a definite improvement in sound quality. -- ----------------------------------------------------------------------------- Pascal Gosselin | gosselin@clik.qc.ca | SIMCO, Inc. - A division of Computer Connection | uunet!clik.qc.ca!gosselin | -----------------------------------------------------------------------------

Well, I tried the suggestion with the headphones and I got high-fidelity hiss. :-) The hiss from the speakers bothered me so much that I finally took them back to the store. I exchanged them for a set of Bose Video Roommates, which can't be run off of batteries like the others could (I didn't want them for the exclusive use of the computer), but they do have one key feature: a volume knob! I can turn them down until the hiss is unnoticeable, and then I just turn my beep sounds, etc. on the mac UP to compensate for the speakers' low volume. Then, if I really want to crank, I can just turn the volume up! Much more convenient than trying to deal with the control panel! --Mike

No wonder you got hisses, since the s/n ratio is way down at low volumes (the volume control is, as far as I can tell, logical, i.e. it converts the data BEFORE the d/a converter) h+ -- --- Stay alert ! - Trust no one ! - Keep your laser handy ! --- h+@nada.kth.se == h+@proxxi.se == Jon Watte longer .sig available on request

I still get hiss when a sound is playing. Before I was getting CONSTANT hiss. That was driving me gaga. --Mike
