One of the nice but annoying things about the Sonosax MiniR82 is how sensitive its meters are. I was getting anomolous non-zero readings when feeding it with a digital signal from a V3 with no signal going into the V3, though I could hear nothing. A friend with good test equipment found that the V3 was an early model without the DC offset circuit engaged, and Grace fixed that for me.
Now I am finding another problem that sounds like the same DC issue that has surfaced with the MR-1 using an external DC power supply. When I use the MiniR82 internal batteries, or the AC supply Sonosax sells for it, I get zero meter readings on line-in with no signal, but when I use a 5-6V DC supply there is a visible if low intensity response on the meters. Does this require a fix to the internals of the MiniR82 (as the V3 did) or is there a noiseless DC power supply out there somewhere?
