PXC 360 BT  
PXC 360 BT  
The PXC 360 BT headphones provide undisturbed music enjoyment in  
noisy environments – even without the constrictions of cables. Their  
circumaural, closed design and the latest active noise compensation tech-  
nology (NoiseGard) make the PXC 360 BT especially suitable for use with  
in-flight entertainment systems. Due to their active and passive attenua-  
tion of ambient noise, they let you enjoy music even in noisy environ-  
ments.  
Bluetooth  
The PXC 360 BT comply with the new Bluetooth 2.1 standard. Via their  
Bluetooth interface, they can be connected to a wide variety of Bluetooth  
enabled devices. Bluetooth wireless technology allows the PXC 360 BT to  
communicate with your Bluetooth enabled device (e.g. mobile phone, MP3  
player, PC or PDA) within a range of up to 10 meters.  
SRS WOW HD™  
SRS WOW HD improves the dynamic audio performance of compressed  
and uncompressed audio by expanding the size of the audio image  
and creating a deep, rich bass response. The patented techniques in  
SRS WOW HD widen the horizontal sound field and raise the vertical sound  
image, retrieving information lost in the mixing process to create a more  
natural audio experience.  
®
apt-X  
With apt-X audio coding, you can be assured of crisp, pure and full stereo  
sound. It allows you to not only hear, but experience and feel the audio as  
it was intended. Utilizing apt-X, Bluetooth technology can now offer wire-  
less audio quality that is indistinguishable from the highest quality wired  
connection.  
From major public broadcasters to film production studios, apt-X is used  
throughout the world to transmit high quality digital audio from A to Z in  
real-time. It was developed to meet the exacting standards of musicians  
and audio engineers who love the exceptional dynamic range and high  
fidelity it provides.  
Now available on selected consumer devices, the apt-X technology ensures  
that music lovers everywhere can stream the rich listening experience that  
only apt-X can deliver.

PXC 360 BT  
NoiseGard™  
The NoiseGard 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 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.  
TalkThrough  
The PXC 360 BT headphones have a TalkThrough function, which allows  
you to communicate with other people without having to remove the  
headphones. When TalkThrough is activated, professional quality micro-  
phones mounted on the outside of the headphones pick up all acoustic  
signals in the immediate vicinity. Annoying background noise is electroni-  
cally filtered out, only allowing the voice of the other person to pass  
through the headphones clearly.  
Additional features  
Great for travel: comfortable, rugged and foldable headphone  
construction  
Optional connection via audio cable for music enjoyment without  
Bluetooth technology  
Outstanding sound quality due to Duofol diaphragms  
Optimum protection against ambient noise due to active and passive  
noise attenuation

Connecting the PXC 360 BT to the audio source  
CAUTION Danger of malfunction!  
The transmitted radio waves can impair the operation of  
sensitive and unprotected devices.  
̈ Only use the headphones in aircraft where wireless  
Bluetooth transmission is permitted or use the audio cable  
instead (see “Connecting the PXC 360 BT using the audio  
cable” on page 16).  
The headphones comply with the Bluetooth 2.1 standard. In order that  
data can be transmitted wirelessly using Bluetooth technology, you have  
to register your headphones with your audio source (pairing).  
The headphones can save the connection profiles of up to 8 Bluetooth  
devices with which they have been paired. After switch-on, the head-  
phones automatically connect to one of these devices.  
If you pair the headphones with a ninth audio source, the saved connection  
profile of the first Bluetooth device will be overwritten. If you want to re-  
establish a connection with the first audio source, you have to pair the  
headphones with this audio source again.  
If your audio source does not have a Bluetooth interface, use an optional  
dongle (see “Accessories” on page 25). In addition to adding Bluetooth  
capability to your audio source, this dongle uses apt-X, a technology that  
ensures crisp, pure and full stereo sound. With apt-X, Bluetooth can now  
offer wireless audio quality that is indistinguishable from the highest  
quality wired connection.  
A connection to the headphones is only possible if your audio  
source supports the A2DP profile.

apt-X audio coding  
Outstanding audio quality apt-X technology is what wireless audio has been waiting for. With apt-X  
audio coding, you can be assured of crisp, pure and full stereo sound. It  
allows you to not only hear, but experience and feel the audio as it was  
intended. Utilizing apt-X, Bluetooth can now offer wireless audio quality  
that is indistinguishable from the highest quality wired connection.  
Professional grade sound Until now, apt-X has been the best-kept secret of the professional audio  
industry. From major public broadcasters to film production studios, apt-X  
is used throughout the world to transmit high quality digital audio from  
A to Z in real-time. It was developed to meet the exacting standards of  
musicians and audio engineers who love the exceptional dynamic range  
and high fidelity it provides.  
Now available on selected consumer devices, the technology ensures that  
music lovers everywhere can stream the rich listening experience that only  
apt-X can deliver.  
Revolutionizing Bluetooth Bluetooth technology has revolutionized our communications and life-  
listening style by eliminating troublesome wires and letting us get on with life “on  
the move”. Listening to a mobile phone conversation on a Bluetooth  
earpiece sounds just fine but when it comes to delivering full stereo sound,  
a little extra help is required. apt-X works within Bluetooth to deliver CD  
quality audio, ensuring you are getting the most from your wireless  
listening experience.  
In order to deliver two-channel digital sound within the Bluetooth A2DP  
profile, audio compression is necessary. While traditional audio compres-  
sion technologies struggle to provide full-bandwidth, high-fidelity audio  
over Bluetooth, apt-X works to ensure you enjoy the fullest, richest sound  
your music collection has to offer.  
apt-X legacy If you have ever been to the movies or listened to the radio then chances  
are you’ll already have heard apt-X in action. Over 20,000 radio stations  
across the world and thousands of cutting-edge film studios rely on apt-X  
for high quality audio delivery.  
The digital compression technology now known as apt-X was originally  
developed in Queen’s University, Belfast, Northern Ireland. The technology  
was first brought to market for radio automation applications to store CD  
quality audio on computer hard drives for direct playout during radio  
shows, hence automating the process of the disc jockey.  
The acclaim the technology received lead to further research and develop-  
ment and throughout the 1990s the technology was used by Broadcast  
and Post-production studios worldwide to deliver high-fidelity, low latency  
audio in situations where bandwidth was limited. The same core principles  
that have earned apt-X worldwide acclaim in the Broadcast and Post-  
Production markets make it the perfect solution for delivering high quality  
audio on wireless devices. apt-X is leading the way in bringing pro-audio  
quality to the discerning consumer.

apt-X audio coding  
apt-X key features:  
Blind listening tests with industry reference audiences have shown  
that apt-X over Bluetooth is indistinguishable from audio delivered  
over wired technology. Unlike psychoacoustic-based technologies such  
as MP3 or AAC, apt-X can be used to transport audio without degrading  
the audio quality. With MPEG/AAC compression, the encoding process  
is destructive and content perceived as “irrelevant” is discarded. apt-X  
transparent, non-destructive approach ensures that every frequency  
present in the original signal is preserved in the encoded and decoded  
signal.  
Dynamic range of > 92 dB for 16 bit audio and > 120 dB for 24 bit audio.  
The overall framework of apt-X ensures a high degree of resilience to  
random bit errors, with the bit error response well matched to the audi-  
tory response of the human ear. apt-X employs connection and  
synchronization techniques to ensure a robust connection and enable  
delivery of audio even under stressful conditions.  
Shortest processing delay of any professional audio compression tech-  
nology. Many current wireless devices suffer from unwanted delays  
which cause lip-sync issues, apt-X can enable real-time delivery of wire-  
less audio ensuring seamless integration when used with video  
devices.  
apt-X encoded audio fits neatly within the available bandwidth of  
wireless transmission standards to offer an efficient solution for band-  
width-restricted connections.

SRS WOW HD  
SRS WOW HD  
Remarkable enhancement for SRS WOW HD™ improves the dynamic audio performance of compressed  
mono and stereo playback and uncompressed audio by expanding the size of the audio image and  
creating a deep, rich bass response. The patented techniques in  
SRS WOW HD widen the horizontal sound field and raise the vertical sound  
image, retrieving information lost in the mixing process to create a more  
natural audio experience. SRS WOW HD also shapes a maximized bass  
response using sculpted filters and driver physics to go beyond the low-  
frequency limitations of speakers and headphones. SRS WOW HD also adds  
Definition™ Control, for realistic clarity, and the new Center Control, for  
dynamic extraction and positioning of dialog.  
Immersive 3D audio SRS WOW HD adjusts the space of the stereo image and eliminates the  
narrow stereo sweet spot and creates an immersive stereo image from  
mono and stereo source material. It also restores audio realism which is  
often masked by traditional recording and playback techniques.  
Center Control SRS WOW HD adjusts the mix of the center information into the stereo  
image. It works in tandem with the space control to create the perfect  
balance, acting as a “zoom” lens for sound. It can bring content to the fore-  
front to dominate the mix or fade it backward, virtually eliminating the  
content all together.  
Optimal headphone listening SRS WOW HD includes techniques based on patented HRTFs to deliver a  
natural, non-fatiguing headphone listening experience by placing the  
perception of the stereo sound image outside of one’s head making it more  
realistic and immersive.  
Elevated sound image SRS WOW HD adjusts the horizontal plane of the audio image from non-  
optimally placed speakers placing it at an appropriate listening level.  
Definition Control SRS WOW HD delivers a livelier, more brilliant sound. The purified sound  
can be heard in musical vocals, high-frequency instruments, and exposes  
details of ambient sound present in the audio source.  
Bigger bass SRS WOW HD includes psychoacoustic bass enhancement techniques  
which enhance the perception of low bass frequencies from speakers and  
headphones which, under normal conditions, can not produce these  
frequencies due to the inherent low frequency cut off and driver size limi-  
tations.  
Audio level management SRS WOW HD includes an audio level management system which monitors  
the output levels of the entire product audio system and manages the  
level dynamically to prevent sudden audio clipping.  
Features of SRS WOW HD  
Stereo enhancement which improves dynamic audio performance  
Sculpted bass response for maximum thump on small speakers  
More natural audio with a wider sound field and raised sound image  
High-definition control for realistic clarity  
Center Control for dynamic extraction and positioning of dialog
