Overview: The AKG Perception 120 USB condenser microphone
that can be used for recording podcasts and for recording with a computer. It
features a built-in 24-bit analog-to-digital (A/D) converter with 128x
oversampling and a USB output. The microphone comes with a tripod adapter, a
tabletop tripod, and a 15' USB cable.
Plug-and-Play: The Perception 120 USB can be used right out
of the box. The mic supports Windows XP, Vista, and 7, as well as Mac OS X
version 10.4 and up, and requires no software installation, additional drivers,
or a reboot. With the USB interface, the Perception 120 USB connects to, and is
powered by, virtually any computer.
Controls: The Perception 120 USB microphone had two controls
on the front panel: an attenuation pad, and a bass-cut filter. When recording
loud sound sources at close proximity, you can apply a -20dB attenuation pad to
prevent overloading the microphone. This allows you to make distortion-free
recordings. The bass-cut filter can prevent low frequency distortion caused by
wind noise and rumble. The filter has a slope of 6 dB/octave starting at 120 Hz.
The bass-cut filter can also be effective at reducing the proximity effect when
the microphone in less than 6" away from the sound source.
Cardioid Polar Pattern: The Perception 120 USBs diaphragm is
located on the front of the microphone rather than the end. The front of the
microphone is designated as the side with the AKG logo. The Perception 120 USB
has a cardioid polar pattern, which records very little sound from the rear. For
best results, you should point the AKG logo toward the sound source to be
recorded, keeping the microphone approximately 8 to 16 inches from the speaker's
Pop Filter: The microphone has an integrated pop filter
which reduces popping when pronouncing plosive consonants (such as "T" or "P").
For optimum results, an external pop screen, such as the PF 80 (available
directly from the manufacturer), is recommended to prevent unwanted blowing and
popping sounds or moisture problems.
