Specs for K3U in my Revue 13 say "12-48v".


Thanks a million Klay. That's what I was looking for.


The sticker inside my K3U specifies the PX23 battery, a mercury type which
is no longer available. The PX23, according to the Sennheiser sticker
inside the K3U specifies the battery voltage as 5.6 volts. As I said in my
earlier post, the SPX23, is a perfect fit. It is rated at 6 volts, not the
3.6 volts I erroneously stated earlier. The K3U also works perfectly on
standard 48 volt phantom power. As far as battery life, I've used the
microphone on location for about 15 hours since putting in a new battery.
The battery still measures 6 volts. So, I think battery life should be
pretty good. I hope this helps.
