CAUTION -
Heavy microphones:
Many microphone and clip or shockmount combinations can be fitted to
guitars using the H-clamp without any special precautions. But heavier
microphones need to be handled with more care. Typical professional vo-
cal microphones and large diaphragm studio microphones are both bulky
and heavy. As long as the clamp can be tightened sufficiently securely, it is
possible to mount these safely on an instrument using an H-clamp but the
following additional precautions must be taken.
1. If the microphone causes the H-clamp’s boom
to swing up or down under the microphone’s
weight (as indicated in picture A), it can only
be used safely in one specific position (picture
B - the ‘captive boom’ position). The H-clamp is
designed so that the boom can be held captive
in the top disk’s boom slot by the microphone’s
weight. In this set up, the instrument can be
moved freely as long as the weight of the micro-
phone continues to hold the boom in its ‘locked’
position. More details about ensuring this locking
is maintained are provided in Section 4.
2. The H-clamp must never be used with a
heavy microphone in an orientation where the
weight of the microphone could cause it to fall
towards the instrument under gravity. For exam-
ple, in the normal attachment sites on an instru-
ment, as long as the instrument is being played,
the heavy microphone should remain securely
locked in position. But if the instrument were laid
on it’s back, the microphones’s weight could pull
it onto the instrument, causing damage to micro-
phone, instrument or both.
3. It is not just the axis of swing on the boom
that must be considered, if the microphone is
heavy enough, it could also either cause the
boom to twist in its grip, or to loosen from the
clip / shockmount enough to allow it to rotate
(see the picture). For heavy microphones it is
therefore important to ensure either that the
grip is secure enough to prevent twisting or that
no damage can result from such twisting.
