Thanks thet --
You
don't say if it is a piano accordion or B/C system or some other
type, but reed layouts may vary, so consider the reed layout.
It's a piano accordion, so the reeds are linearly arranged. Doing
some tests (with a single Primo omni Simplest P48 inside the
right-hand side) I do hear a strong difference for the reeds near
the mic, as expected.
I
would think two mics on the keyboard and one or two on the bass
would be sufficient.
Glad to hear that this and Jerry's experience accord with each
other.
There
are better circuits than P48 that aren't really much more effort
if you are going to the trouble of installing multiple mics in an
accordion.
Interesting... what did you have in mind? I have made so many
S-P48's and they've been great, and given how simple and effective
they are, and that I don't need low noise performance in this
application, Simplest P48 seemed the natural choice?
If
you draw the circuit you intend we can comment better on the
mixing - seems to me in a mixer each capsule needs its own
resistor into the summing amp, just shorting together the capsule
fet outputs seems wrong to me.
Yeah the plan was to literally parallel multiple capsules on a
standard P48 circuit, so, .
IIRC it has been discussed a couple times here that this works
(and gives a little less noise) so it seemed like the easy way to
deal with mixing the signals from the capsules without having to
engineer some kind of active mixer as well... but I have no idea
if there are subtle consequences, so let me know if I'm missing
something.
