Topic: R4 run times

[Nick's Picks]

cool.
it probably does go down to 7v ish.  (the ua5 that is).

fwiw...
the ua5 will power up w/7v, but it will not provide phantom.
it needs 9v min.
not really related to the thread, but it was discussed on age 7-8

The R-4, like the UA-5, has reversed polarity relative to most units and most batteries.  Most units require, and most batteries and cables provide, (+) tip and (-) ring, whereas the R-4 and U5 take (-) tip and (+) ring.
