I
learned about Symmetrical Impedance from the DPA website below.
?
I hate to say this, but te dpa site's technical readings are
sometimes inaccurate or simply confusing. I know that they are
redacted by junior engineers who are not very scientifically exact.
So,
generally, the Output Impedance provided refers to the
impedance between Pin 2 and ground, a
No. The impedance between either pin 2 or 3 is somewhat parasitic.
It's almost never specified.
nd
when a microphone is described as 'balanced,' it means that
the impedance between Pin 3 and ground is identical to that of
Pin 2 and ground, correct?
Although they should, not always. For example a Schoeps mic has
different impedances. The difference is minor but it exists. It's an
example of an imperfect balanced connection.
In that respect, transformer-balanced mics are different than
transformerless.
Typically, dynamic (moving-coil or ribbon)mics have nominally
infinite Z between pins and ground (actually several 100 Megohms).
Phantom-powered mics have about 1-10kilohms bertween pins and
ground, when they have about 50-200 ohms between pins 2 & 3.
