Balanced audio inputs are differential and are more immune to RFI.

Assuming the preamp offers both balanced and unbalanced outputs, is
there any advantage of one vs the other?
If anyone decides to try the preamp idea, and by chance you are using
a ribbon mic, be sure the preamp has the option to disable the phantom
48v power. Many of the less expensive preamp mixers don't offer that
option.

Personally, I would not generate additional gain from the software
DSP (mic boost), but would use a microphone preamp and use its
line level output to drive the FLEX-5000. For best SNR, you want
all of the required gain to come from the first gain "stage" in
the AF signal path. The little Behringer mixers are cheap.

Fellow flexers...
On the Flex 5000a is it normal to need "Mic Boost" (selected
from Audio
menu) to in order use a balanced mic such as a Shure SM58?
I could not generate enough audio level without activating
"mic boost" with
my Shure.
Yet using a standard Yaesu fist mic in the front panel socket
does not need
Mic Boost...
Is this to be expected?
Thanks
