i tried a simple, not so scientific test with my 460's. moving a paradise pizza (no affiliation) refrigerator magnet close to the capsules had a noticeable effect on the sound... it seemed to lower the levels.
Good way to test
worst case magnetic effects, AND is a
potential issue!
Fortunately, even a most magnetic sensitive mic has good chance of working normally
INTRODUCING
the production model of the "GRAV-CLAMP"
with ~3" overall length
universal collar accommodating up to 1.5" dia. mics. More importantly, the GRAV motor mounts a safe distance well behind the diaphragm, AND has mic-side sufficient magnetic shielding to not mag-lockup output mics with transformer. Designing good shielding
is not difficult, and with performance benefits, so expect no mag-effects issues whatsoever in refined production models.
The GRAV-CLAMP features easy and fast mic mounting after
just one setup experience!
Quick Instruction: AFTER
the
slacked mic cords are carefully secured at point where mic is about center inside clamp's
fixed outer hull , clamp's movable
collar now easily slides along the body
, quickly locking-down
a
little behind equilibrium balance position of floating collar+mic body. This adds needed mass-loaded
forward bias to offset the slacked cord's vectoring effect.
First setup will take much time and care,
and it's most important to find
and mark cord/collar positions with label or permanent pen.
When already knowing exact mic mounting positions,
repeating the setup is easily done in a few minutes using
same mic + cord combination.
Bottom line is a practical magnetic mic suspension is
still a GO waiting to happen!
