Regarding audio quality with the FLEX-3000. In the old days, the rule of
thumb was to minimize the number of active audio stages to minimize
noise and distortion. (The ideal was said to be a straight wire between
the microphone and the speaker!) The FLEX-3000 manual does not say much
about the use of the FlexWire balanced line input vs. the unbalanced
RJ-45 microphone input. Does the FlexWire line input involve fewer
preamp stages or is its audio signal simply attenuated? If simply
attenuated, it would seem that the use of an external microphone
preamp/processor will not reduce noise and distortion, even though the
external compression or equalization functions may be more sophisticated
than those built-in the FLEX. And, I would guess that with the
microphone connected directly to the FLEX via its RJ-45 connector, fewer
chances exist for ground loops or other RFI issues. So, any advice would
be appreciated.
