ULE technology and new design
PROline with ULE stands for Ultra Low Emission and means significant benefits for professional users as it is highly developed and specially designed for professionals. The new design does not only distinguish the professional line but also allows due to more ear anatomy area a higher degree of transparency in combination with the spatial sense and understanding.

The ULE technology was systematically developed for professionals 
as they do spend half of their lives in headphones. Most headphone drivers convert an electric signal into an acoustical signal, producing low-frequency magnetic fields. In response, ULTRASONE developed a special MU Metal shielding (ULE technology) to reduce the radiation by up to 98% compared to current headphones. The ULE technology has stood the test of international review and is recommended by technical surveillance organisations.

S-Logic™ Natural Surround Sound
Through the S-Logic™ Natural Surround Sound the usual headphone sound will be moved out of the head in the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived - it’s just like being in a live concert. 
For this new technology additional equipment is not required. Take 
a pair of ULTRASONE headphones plus your sound device and you will be ready for the 3-dimensional enjoyment!

Safer hearing
S-Logic™ Natural Surround Sound allows an up to 40% lower 
dB output (3-4 dB) for the same loudness sensation. This may significantly reduce the risk of hearing damage while ensuring 
hours of fatigue-free listening - an absolute must if you spend 
a lot of time in headphones. 

Character
Using the same stiff titanium-plated driver as PROline 750 within an open-beck design, PROline 2500 will provide you with the most airy sound within the complete line. If you don´t need a closed-back design the PROline 2500 will satisfy your expectations with the most proper, accurate and finest sound reproduction.

Due to professional needs and requests we implemented an additional function which enables you to fold these headphones for a compact storage and easy transportation in a suitcase.

 

Edition9 
is hand-made in Germany. Edition9 is a new pair of headphones with extraordinary qualities. Designed and manufactured with a maximum of attention. You are interested in a pair of headphones with the most sophisticated sound system and the most exclusive materials. Exclusive beauty and high technology at the same time. Take your time and enjoy the finesse in manufacturing and choice of materials. 

The specifically created box allows you to store your Edition9 safely and convenient even for transportation. The earcups are black ruthenium-plated and the insignia on the earcups is made of chrome-plated brass, crafted in Bavaria. Earpads and head pad are made of soft genuine Ethiopian hair sheep leather in dark grey. This is the finest leather available with convincing attributes. This leather is so soft and smooth that you barely feel the headphones on your ears and it provides an excellent isolation. Your Edition9 is equipped with titanium-plated drivers and polished MU Metal shieldings for reduced magnetic field emissions. The set also contains a gold-plated adapter 6,3/3,5 mm. This combination of selected materials and ULTRASONE technologies presents the exceptional accurateness of your Edition9 headphones. Only manufacturers having proved their high standard and qualities by working with the most exclusive and luxurious automotive brands were chosen as suppliers for the realisation of Edition9.

Due to the great feed-back regarding the sold out “Edition7 limited” series, the Edition9 headphones have been developed to meet our customers special requests in design and sound. Edition9 is not limited and disposes of the highest quality materials and the most precise and natural sound appearance. 

S-Logic™ - ULTRASONE´s 
Natural Surround Sound
The patented S-Logic™ technology is described as Natural Surround Sound. No other digital surround system can compare with this new standard. As the sound of normal headphones will sound direct and even on both sides, the S-Logic™ system pushes the sound around your head! It appears as though you are listening to speakers meters away. Even at very low levels, this spacious sound allows you to hear precisely. Edition9 uses titanium-plated drivers which offer the most accurate and finest sound reproduction. And on top, the S-Logic™ technology does not require additional electronic equipment!

How does S-Logic™ work?
S-Logic™ sends music around your head not just into it, because this technology uses decentralized driver positioning. Did you know that all of us use and need the outer ear for 3-dimensional hearing to define the direction and the distance where a sound comes from? Instead of hitting the inner ear directly, with S-Logic™ the signals are reflected off the surface of the outer ear in different directions before entering the auditory canal to create a natural 3-dimensional sound. S-Logic™ is the only headphone system which includes your entire sense of hearing. S-Logic™ does not change your personal hearing. It intensifies it for your individual needs and listening pleasure. S-Logic™ does neither need artificial echo nor digital processing or cross over run time delay (like DSP). You can hear the music just the way the sound mixer produced it. 

ULE technology - ULTRASONE´s 
MU Metal shielding for reduced magnetic field emissions 
ULE stands for Ultra Low Emission. The ULTRASONE ULE technology was systematically developed for professionals as they do spend half of their lives in headphones. Most headphone drivers convert an electric signal into an acoustical signal, producing low-frequency magnetic fields. In response, ULTRASONE developed a special MU Metal shielding (ULE technology) to reduce the radiation by up to 98% compared to current headphones. All professional ULTRASONE headphones are basically equipped with the ULE technology. Certainly your Edition9 headphones may not miss the ULE technology. The exclusiveness of your Edition9 calls for the ULE standard. This patented technology has stood the test of international review and is recommended by technical surveillance organisations.

ULTRASONE´s 
concept for safer hearing
The S-Logic™ technology does not only create a Natural Surround Sound. S-Logic™ allows at the same time a lower dB output (3-4dB) for the same loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, ULTRASONE generally advises not to listen to music at high volumes to prevent hearing damage.

Many audiophiles use headphones to enjoy their system. While some people are compelled to do so by their living circumstances, others simply prefer cans to loudspeakers. However, some amplifiers either have no headphone output, just as they don't have phone stages, or if they do have one, it is often just a simple IC-based stage. Regrettably, even many outboard amplifiers resort to this simple - and cheap - solution, making it impossible for headphones to perform at their best. Let us introduce the CanAmp, offering a no-compromise solution at a realistic price - in fact, given its technology and manufacturing quality we might even say at a "discount" price.

Headphones can be considered as high quality loudspeakers, but with a much lower power requirement. For this reason, they have distortion levels an order of magnitude lower than conventional speakers, and therefore are capable of showing up amplifier deficiencies more clearly. What's more, headphones are one-way systems, with very few exceptions, and for this reason crossovers do not interfere with sound quality. Consequently, a headphone amplifier must offer the best possible sound quality, even at very low volume levels, whilst working not unlike a real power amplifier.

The CanAmp is a two-stage amplifier. While the first - voltage gain - stage is based on an integrated circuit of the highest audio pedigree, the second - power gain - stage is a single-ended, pure Class-A amplifier. It enables the CanAmp to drive virtually any headphones from 8 ohms up to 600 ohms. As its output power (at 8 ohm) is nearly 1W, the CanAmp could drive even a high-sensitivity loudspeaker!

The unit has no internal wiring, and the signal path is kept to a minimum on its PCB.

Its high-quality, 1 dB-tolerance Blue Alps volume pot goes through a further selection process during manufacturing to achieve an even tighter, 0.5 dB tolerance.

The CanAmp not only has a line-level input but offers a line-level output to boot; it can therefore be connected to the TAPE MONITOR output of an amplifier, leaving the TAPE output free for additional components (MP3, MiniDisc, CDR, etc.). Gold-plated RCA terminals are used, and soldered directly onto the fibreglass PCB.
