PXC 450 Headphones

The PXC 450 is a closed, dynamic, ear-enclosing stereo

headset with newest-generation active noise

compensation (NoiseGard 2.0) for use, for example,

with inflight entertainment systems. Passive and active

tone suppression together enable brilliant music

enjoyment even in noisy environments.

PXC450_517600_0806_SP6.book Seite 4 Donnerstag, 13. September 2007 10:26 10

TalkThrough

TalkThrough allows direct communication with your

environment, even while wearing headphones. The

NoiseGard 2.0 and peak level protection remain

active, and your hearing remains protected.

NoiseGard 2.0

The active noise compensation, NoiseGard 2.0, is

based on the principle of deleting tones in the low

frequency range (to 1 kHz) with inverse tones (phase-

inverse tone). Tiny microphones record the ambient

noise. NoiseGard 2.0 electronics creates a sound wave

that is phase-inverted by 180° to the interfering tone

- resulting in the two sound waves almost canceling

each other out.

Additional features

yExcellent sound quality through patented adaptive

baffle damping and duofol diaphragm system

yIdeal for traveling: comfortable, sturdy and folding

design with one-sided cable connection

yPerfectly suited for use in inflight entertainment

systems as well as mobile music sources

yHeadphones can also be used without cable to

dampen noise

Adjusting headband

In order to achieve good sound transmission and noise

damping, as well as the most comfort, adapt the

headband to your head size. You can adjust the

headband using the snap-in locking mechanism.

왘Wear the headphones so that the headband runs

across the middle of your head.

왘Adjust the headphones so that

–theearcushioncompletely surrounds the ears,

– you feel slight pressure around your ears,

– the headband is flat on the head.

왘Check in a loud environment whether the ear

cushions are optimally placed to ensure maximum

noise damping.

Connecting the headphones

왘Connect the audio cable  to the headphone

bushing of your sound source.

You will hear the sound from your sound source.

If the plug on the audio cable does not fit:

왘Use the adapter for 6.3-mm plug bushing (see

illustration to the left).

If you wish to use the headphones for the inflight

entertainment in an airplane:

왘Use the inflight adapter  (see illustration to the

left).

Daily use

Adjusting the volume

왘Use the VOLUME + button or the VOLUME –

button , to adjust the volume.

Note:

The volume of the TalkThrough signal does not

change.

Listening loud? - No!

People like to listen more loudly with

headphones than with speakers. Loud

volumes for extended periods of time

can lead to permanent hearing loss.

Protect your hearing! Sennheiser head-

phones also sound very good at low

volumes.

CAUTION!
