DESCRIPTION:
The
PV@
is a cardioid unidirectional
dynamic microphone designed for
applications in which a built-in “on/off”
switch is desired. With a clean, natural
speech response and good noise and
feedback rejection, the PV is an ideal
microphone for vocals, church and
institutional systems, meeting rooms,
auditoriums, and some instruments
almost anywhere in which convenient
local control of the microphone is
required. The PV mic has been
-
re-fashioned to make it attractive in any
setting. An integral acoustic foam pop
and wind filter provides effective control
of plosive sounds and moderate wind.
The internal shock-mounting system
minimizes handling and stand noise.
The PV is a rugged, reliable
microphone well-suited for rental
systems, convention centers and similar
rough usage applications. The PV mic
gives the look, feel, and performance of
expensive professional microphones at
a fraction of the price. Also available
in Hi
Z.
NOTE: The switch mutes the
microphone by directly shorting across
the dynamic element. Microphones with
this type of switching should not be
used if more than one microphone is
connected to the same input, since the
“off” function on one microphone will
also short any other unit connected to
that input. If this type of operation is
required, the use of a transformer-type
microphone combiner is suggested.
(Another possible alternative is to rewire
the PV so that the switch is used to
open one side of the line for
(‘off.“)

Proximity effect is a naturally
occurring phenomenon in
unidirectional microphones. The
effect is to accentuate or boost the
low frequency response. This
effect is a function of distance
from the diaphragm to the source
and increases as the diaphragm is
moved closer to the source.

For high impedance
mics,
cable lengths
of 25’ or more and input impedance
not less than 20 kilohms are not
recommended due to loss of signal
quality.
