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.

PXC350_515699_0607_SP6.book Seite 4 Dienstag, 5. Juni 2007 11:47 11

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 1 kHz) 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° out-of-

phase), the effect being that the polarity reversed

signal cancels most of the outside noise.

Additional features

yOutstanding sound quality due to patented

adaptive baffle damping and Duofol diaphragms

yOptimum protection against ambient noise due to

NoiseGard Advance active noise compensation

yGreat for travel: comfortable, rugged and foldable

headphone construction with single-sided cable

yDesigned for use with in-flight entertainment

systems and audio, video and game consoles

yWithout the detachable audio cable, the head-

phones can be used as passive hearing protectors

Adjusting the headband

For optimum transmission quality, good noise

attenuation and best possible comfort, the headband

has to be adjusted to properly fit your head:

왘Wear the headphones so that the headband 

runs over the top of your head.

왘Adjust the length of the headband so that

– your ears are completely inside the earpads ,

– you feel even, gentle pressure around your ears,

– a snug fit is ensured.

왘Final adjustment is best made in a noisy environ-

ment!

Connecting the headphones

왘Connect the audio cable to the headphone

socket of your sound source.

You hear the sound from your sound source.

If the plug on the audio cable does not fit:

왘Slip on the audio adapter for ¼" (6.3 mm) jack

socket (see diagram on the left).

If you want to use the headphones with an in-flight

entertainment system:

왘Slip on the in-flight adapter  (see diagram on the
