Instructions
for use
The PXC 350 headphones
The PXC 350 are closed, dynamic, circumaural stereo
headphones
with NoiseGard Advance active noise
compensation technology, designed
for use with e.g.
in-flight entertainment systems. Passive and active
noise reduction enable you
to enjoy music even in
noisy environments.

NoiseGard Advance
The NoiseGard Advance active noise compensation
system
is based on the principle of cancelling out
sound using "anti-sound" (phase-inverted sound).
Tiny microphones pick up low-frequency
ambient
noise (up to 1kHz) near the ear. The NoiseGard
Advance electronics use
this noise to generate a
sound wave which
is the exact opposite (IE: at the •
same level
but polarity reversed - 180
0
out-of-
phase), the effect being that the polarity reversed
signal cancels most
of the outside noise.
Additional features
•Outstanding sound quality due to patented
adaptive baffle damping and Duofol diaphragms
•Optimum protection against
ambient noise due to
NoiseGard Advance active noise compensation
•Great
for travel: comfortable, rugged and foldable
headphone construction
with single-sided cable
•Designed
for use with in-flight entertainment
systems and audio, video and game consoles
•
Without the detachable audio cable, the head-
phones
can be used as passive hearing protectors
