• We strongly recommend the use of a pop shield or
fi lter for all vocal recording. These aid in minimising
plosive sounds (hard ‘P’, ‘B’, ‘T’ and ‘K’ sounds)
that produce a sudden jet of air which can cause
the capsule to overload and produce a ‘popping’
sound.
• Any moisture on the microphone capsule can
cause problems for condenser microphones,
however the use of a pop shield or wind shield
(optional accessory WS2) will reduce the risk of this
occurring.
• Placement of the microphone and pop shield
relative to the vocalist may be varied on several
factors including room acoustics, the vocal
performance, and whether the vocalist has a high
or deep voice.
• An ideal reference is to begin with the pop shield
directly in front of the vocalist, and approximately
15cm (6”) away from the microphone. This will assist
in keeping the performer at a constant minimum
distance from the microphone and helps to
maintain reasonable recording levels.
• Experimentation should be made with the angle
from which the microphone is addressed, as
different results can be achieved when the vocalist
is ‘off-axis’ to the microphone (and the gold dot).
• If an earth loop is present (a mains frequency hum)
there is a ground lift switch on the rear panel of
the power supply, which should be raised to the
‘lift’ position. This earth loop can appear when two
devices which are both earthed are connected
together.
