MAGNETIC STRAY FIELDS
MICROPHONE POSITIONING
Always use a sturdy microphone stand with R44 series microphones.
Weighing around 8lbs, mounting R44 series microphones on a
strong, robust microphone stand with a heavy base (or tripod) is
essential. Large studio-booms with an appropriate counter-weight
are recommended to prevent your R44 from tipping-over and
crashing, causing injury to itself, a musician, or a valuable musical
instrument.
The integrated cushion mount was designezd to keep structure-
borne noise transmitted through the microphone stand and the
cable away from the low-tuned ribbon transducer. For the shock
mount to function as intended, it is important to position the
microphone with the cushion mount vertical and rotating the
microphone within the yoke. This requires the use of a swivel
Ribbon microphones are fundamentally prone to picking up
strong external magnetic fields caused by light dimmers or nearby
power transformers. Guitar players will know this phenomenon
from single-coil pickups. Even though much attention was paid to
suppressing such sensitivity to external magnetic fields in the design
of your microphone, it is still possible that you might encounter
this problem. If you should pick up a hum, try rotating or moving
the microphone to find a spot where the hum disappears, and try
eliminating potential sources of stray magnetic fields. You can use
the microphone to find where hum is originating. Rotate the mic
for maximum interference and move it back and forth to sense its
direction.
The high-performance magnets used in AEA microphones are
incredibly strong, and a significant amount of stray magnetic field
lines surround the microphone. Avoid placing the microphone
in close proximity to hard drives, credit cards, analog tape, or any
other magnetically sensitive items to prevent any data loss.
