MM 550-X
MM 550-X
The MM 550-X is an accessory which allows for wireless music enjoyment
when used with mobile phones or other Bluetooth devices/Bluetooth
compliant devices. Its circumaural, closed design and the latest active
noise compensation technology (NoiseGard) makes the MM 550-X especially suitable for use with in-flight entertainment systems. Due to its
active and passive attenuation of ambient noise, it lets you enjoy music
even in noisy environments.
Bluetooth
The MM 550-X complies with the Bluetooth 2.1 standard. Via its Bluetooth
interface, it can be connected to a wide variety of Bluetooth enabled
devices. Bluetooth wireless technology allows the MM 550-X 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 HDTM
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 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.
NoiseGardTM
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.
4 | MM 550-X
MM 550-X
TalkThrough
The MM 550-X has a TalkThrough function, which allows you to communicate with other people without having to remove the headset. When TalkThrough is activated, professional quality microphones mounted on the
outside of the headset 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 headset clearly.
Additional features
•
Great for travel: comfortable, rugged and foldable headset 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

SRS WOW HD
Remarkable enhancement for
mono and stereo playback
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. SRS WOW HD also shapes a maximized bass
response using sculpted filters and driver physics to go beyond the lowfrequency 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 forefront 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 nonoptimally 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
limitations.
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.

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
listening
Bluetooth technology has revolutionized our communications and lifestyle 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.
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 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 Post_Production markets make it the perfect solution for delivering high
quality audio on wireless devices. apt-X is leading the way in bringing proaudio quality to the discerning consumer.

apt-X key features:
28 | MM 550-X
•
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.
