Description
The AT2020 is a side-address fixed-charge condenser
microphone
with
a
cardioid polar pattern.
It
is designed for project/home studio applications.
The microphone requires 48V phantom
power
for operation.
The cardioid polar pattern
of
the
microphone is
more
sensitive
to
sound
originating directly
in
front
of
the
element, making
it
useful
in
controlling
feedback, reducing pickup
of
unwanted sounds and providing isolation
between
performers.
The
output
of
the
microphone is a 3-pin XLRM-type connector.
The microphone is enclosed in a rugged housing. The included stand
mount
permits mounting on any microphone stand
with
5/s''-27
threads. A
soft
protective pouch is also included.
Operation
and
Maintenance
The AT2020 requires 48V phantom
power
for operation.
Output
is
low
impedance (Lo-Z) balanced. The signal appears across Pins
2 and 3;
Pin
1 is ground (shield).
Output
phase is "Pin 2
hot"-positive
acoustic pressure produces positive voltage at
Pin
2.
To
avoid phase cancellation and poor sound, all
mic
cables
must
be
wired
consistently:
Pin
1-to-Pin
1,
etc.
An Audio-Technica
emblem
is on
the
front
of
the
microphone. Position
this side
of
the microphone
toward
the
sound source.
In
use, secure
the
cable
to
the
mic
stand or boom, leaving a slack loop
at
the
mic. This will ensure
the
most
effective shock isolation and reduce
the possibility
of
accidentally pulling
the
microphone
out
of
its
mount.
Avoid leaving
the
microphone
in
the
open sun
or
in areas
where
temperatures exceed 110° F (43° C) for extended periods. Extremely high
humidity
should also be avoided.
