AKG Acoustics PERCEPTION 120 - Manual (Page 25)

Operation
Perception USB 25
The front of the microphone is the side of the
housing with the AKG logo. The Perception 120
USB microphone has a cardioid polar pattern so
it records very little sound from the rear. Always
point the logo towards the sound source to be
recorded. The microphone should be 20 to 40
cm (8 to 16 inch) from the speaker's mouth in
order to obtain the best results.
ATTENTION
Risk of damage Risk of damage Risk of damage Risk of damage
Keep the microphone dry.
Moisture directly entering the capsule during use of the microphone (singing a
short distance away, high air humidity) can cause crackling in the microphone as
tiny short-circuits can short-circuit the polarisation voltage.
When recording wind instruments, speech or singing ensure that you do not sing
or blow directly into the microphone.
NOTE
For optimum results, we also recommend the optional PF 80 pop screen to
prevent unwanted blowing and popping sounds or moisture problems.
NOTE
When using the microphone outdoors, use the optional AKG W 4000 windscreen
to protect the microphone from moisture and to reduce wind noise.
