<p class="MsoNormal">Or ditch the bluetooth speakers and install regular speakers running from an amp. You could go 70V or standard without issues at those distances, though 70V would probably be easier.<o:p></o:p></p>

<p class="MsoNormal">Hey all, I wanted to move audio from my media pc to rooms in my home<br>
and I was wondering if anyone had suggestions on an inexpensive piece<br>
of gear that'll do that. I just want to listen to podcasts and some<br>
music while i'm doing stuff around the house, nothing high quality,<br>
but I'd prefer not to have hum and static and strong high freq<br>
rolloff. I'd prefer to do this in analog so that I can turn on<br>
multiple speakers and they're in phase. I'll be moving the audio over<br>
a distance of ~ 10-15 meters to 4 different zones. In the target rooms<br>
I'm going to hook up inexpensive bluetooth speakers with aux input<br>
running off of a usb wall wart.<br>
<br>
Also looking for inexpensive European (Schuko-style) USB wall warts<br>
that don't have a lot of ripple. I have tried a bunch (~10?) of<br>
different usb power supplies over the years and almost all of them<br>
make the speakers buzz audibly. The only one that I have that doesn't<br>
do that is an ancient Samsung one that I got with I think my Galaxy<br>
S3. I hope it never dies to be honest.<br>
<br>
Obviously a better power supply circuit in the bluetooth speakers<br>
would make them not buzz, but I tried two different ones (starting<br>
with Anker Soundcore 2 and most recently Earfun UBoom L) and they all<br>
do that so... it is what it is.<br>
<br>
Best regards<br>
