Dear Jerry,?
?
Thanks to your reply.
?
Earthworks Homepage's M23R Spec :
?
OUTPUT IMPEDANCE ? ?65Ω balanced (between pins 2 & 3)
?
This is the specification provided on the website.
What I mean here is not the Symmetric impedance between Pin 2 and Pin 3?
I think R1 + R2 = Symmetric impedance.
?
If so, 130 Ohm would be the output impedance, but I wonder if Earthworks is providing 65 Ohm.
?
haha, Thanks to you, I am building up my knowledge.
