PXC 310 BT

The PXC 310 BT headphones provide undisturbed music enjoyment in noisy environments – even without the constrictions of cables. Their supra-aural, closed design and the latest active noise compensation technology (NoiseGard) make the PXC 310 BT especially suitable for use with in-flight entertainment systems. Due to their active and passive attenuation of ambient noise, they let you enjoy music even in noisy environments.

Bluetooth

The PXC 310 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 310 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.

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 wireless 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.

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 310 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 microphones mounted on the outside of the headphones pick up all acoustic signals in the immediate vicinity. Annoying background noise is electronically filtered out, only allowing the voice of the other person to pass through the headphones clearly.

PXC 310 BT

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 patented adaptive baffle damping and Duofol diaphragms

• Optimum protection against ambient noise due to active and passive noise attenuation

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-

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 compression 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.

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 development 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 PostProduction 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’s 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 auditory 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 technology. Many current wireless devices suffer from unwanted delays which cause lip-sync issues, apt-X can enable real-time delivery of wireless 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 bandwidth-restricted connections.
