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.
While gobo isolation panels can be effective in isolating performers
from each other, they introduce their own set of problems - including
reflections close to the performers and/or microphones that result in
comb-filter distortions. Because gobos usually are bulky and occupy
valuable floor space, they also inhibit the ability of the musicians to
hear and see each other easily. Such a setup requires complex and
often cumbersome headphone monitor mixes for the musicians.
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.
