Description
The AT2020 USB is a side-address xed-charge condenser microphone
with USB digital output (Windows and Mac compatible) and a cardioid
polar pattern. Designed to plug directly into a computer’s USB port, the
microphone is ideal for digitally capturing music or any audio source using
your favorite recording software. The microphone offers studio-quality
articulation and intelligibility perfect for home studio recording, eld
recording, podcasting and voiceover use.
The microphone requires USB Power (5V DC) for operation; this is
supplied through the computer’s USB port via the included USB cable.
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 USB-type connector. The microphone
has a bit depth of 16 bits and a sample rate of 44.1 kHz.
The microphone includes a 3.1 m (10') USB cable that connects the
microphone to any computer with a USB port.
The microphone is enclosed in a rugged housing. The included pivoting
stand mount permits mounting on any microphone stand with 5/8"-27
threads. A tripod desk stand and a soft protective pouch are also included.
Operation and Maintenance
The AT2020 USB is designed to plug into a computer’s USB port.
Detailed instructions for setting up the microphone with Mac OS X,
Windows XP, and Windows Vista are included with the product and
available online at www.audio-technica.com.
It is important to position the microphone directly in line (on axis) with
the person speaking/ singing or instrument (or other sound source) to
achieve the best frequency response of the microphone. For use in
speaking/singing applications, the ideal placement for the microphone is
directly in front of the person speaking/singing. The same placement is
optimal when miking an instrument such as an acoustic guitar, drums or
piano. Experiment with different mic placements to nd the best sound
for your particular setup.
Set up the microphone with included pivot mount and tripod desk stand
as follows: First, screw the pivot mount onto the top of the tripod desk
stand. Next, place the tripod desk stand on a at surface. (The tripod
legs will extend to provide a wide, secure base.) Install the AT2020 USB
microphone into the threaded collar of the pivot mount and tighten collar
while holding the microphone in place. The front of the microphone
should be facing the sound source. (A USB icon and blue LED indicate
the front of the microphone; the product model number is displayed on
the rear of the microphone.) If necessary, adjust the microphone’s angle
with the pivot mount’s thumbscrew. Plug the provided USB cable into the
USB digital output at the base of the microphone.
Avoid leaving your 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.
