Hi Rich,
I made the same decision regarding the use of balanced mics. I also
built a box using LM194s and LM833Cs. No complaints about its use
except that generating 48 volts for phantom power was a challenge
without the use of an inverter (not used because of efficiency vs
battery discharge rate). I didn't fancy the idea of carrying a heavy
battery pack everywhere so record time with NiMh batteries is limited
with the internal ones. The performance and noise rejection is
astounding over unbalanced ones and opens up new worlds with regard to
the choice of different microphones. The box has dual channels, a
mixing function, internal charger etc. The chip you're using looks
interesting and wait for your posting relating to this.
Cheers,
David.
PS: Sadly Australia, like the US, has not opted to adhere to the Kyoto
protocol. Word has it that the powers-that-be do not wish to affect
our energy production! I've much to say on this but I think my
sentiments are already shared throughout this group.
