A FIGURE-OF-8 MICROPHONE
Figure-of-8 microphones
are constructed with
positive polarity on the
front and negative polarity
on the back. Positive
pressure on the front side
of the ribbon produces a
positive voltage on (Pin-2),
with respect to (Pin-3) on
the output connector.
The sound of your R84 series microphone is slightly different
between the front and the back — subtle, but sufficient to offer two
“flavors.” In addition to polarity, this is the result of using two wraps
of grille cloth on the back and only one on the front. When using
the rear lobe, remember to invert the polarity on your preamp or
DAW. This ensures your recordings with the back lobe will be in-
phase with other microphones.
HOW TO MINIMIZE BLEED
A significant and ever-present challenge in contemporary studio
recording is minimizing leakage from nearby instruments into the
various microphones. The deep nulls of ribbon microphones provide
good rejection of unwanted sounds, which can be beneficial in
sound reinforcement situations where feedback is always a threat.
