Adam Hall Group Showcases World Premieres at Prolight + Sound

At this year’s Prolight + Sound (April 4th to 7th) in Frankfurt, the Adam Hall Group will unveil several world premieres in Hall 3.1 #E60-F70. At the same time, the German company will announce its collaboration with the legendary Porsche Design Studio.   

At the start of the exhibition, our pro audio brand, LD Systems®, will unveil its near production concept for a future-oriented sound product, which has been developed in collaboration with the Porsche Design Studio. “Our development team, together with the designers from the Porsche Design Studio, have done a first-class job. We are introducing a brand new kind of design into the industry. I am really looking forward to seeing the reactions in the market,” says Alexander Pietschmann, CEO of the Adam Hall Group.

“This integrative design has never been seen before on the market and makes no compromises on sound quality, but is technically unique,” says Porsche Design Studio designer Jörg Tragatschnig, who has worked with his team on the design. And these could be ideal conditions for a new status quo in professional music reproduction. More information at

MDG Named North American Distributor for Gravity, the New Premium Stands Brand from the Adam Hall Group

Press Release

MDG Named North American Distributor for Gravity, the New Premium Stands Brand from the Adam Hall Group

New Jersey, USA / Neu-Anspach, Germany – February 14, 2017 – Musical Distributors Group (MDG) was officially named the exclusive North American distributor for Gravity® Stands, an award winning, premium stand brand under the Adam Hall Group umbrella.

Gravity® is the new Adam Hall Group brand for premium stands that comprises high-quality products for all stage and studio needs. Through many innovations, such as a customizable marking concept, soft touch elements and the focus on design, the Gravity® brand challenges the often undistinguished image of stands and accessories and facilitates the work of musicians and stagehands alike.

Designed and engineered in Germany, this new brand was launched in 2015 with more than two years of intensive research and development work behind it. Using powder-coated metal with double-injection-molded ABS plastic, die-cast zinc components, and soft touch rubber-coated clamps and knobs, make the Gravity® Stands ultra-durable and built to last. In addition to the superior materials used in the construction of the stands, the brand specific multi-colored “G-Rings” add a touch of style, as well as convenience, to these on-stage necessities.

“We're extremely pleased to officially be taking on this line of high-quality product” explained Steven Savvides, president of MDG, “It's wonderful to be able to carry all of the Adam Hall brands and bring the final component of their reputable product engineering to North America, as well as strengthen our relationship with the Adam Hall Group.”

Considering their previous work with all of our other brands, it is great to see them complete the collection of our products and continue to represent our company to its fullest extent” stated Markus Jahnel, COO of the Adam Hall Group.

Gravity® Stands have won the German Design Award, as well as a Red Dot Award, and have no intention of ceasing their innovation in the future. “Adam Hall Group – with the help of MDG – is re-defining the term Gravity® in the United States, and contrary to the brand name, it can only go up from here” smiles Savvides.

Ultrasone Announces a New Headphone Masterpiece to Celebrate Their Anniversary!

The Jubilee Edition 25: limited to only 250 units worldwide!

A quarter of a century of high-end hi-fi for completely private music enjoyment: the first Ultrasone headphones came onto the market 25 years ago. The Bavarian headphone manufacturers are celebrating this anniversary with a unique masterpiece: the Jubilee Edition 25. Limited to 250 units worldwide, the high-end headphones mark this anniversary year with perfection in sound, design and workmanship. And they represent the expertise that comes from 25 years of continuous development addressing all the senses: titanium-coated Mylar sound transducers and S-Logic® EX technology combine with ear cups made from Makassar ebony to produce a unique flagship with perfect workmanship

Celebrating 25 Years of Ultrasone Headphones With a Masterpiece

Ultrasone, the Bavarian headphone manufacturer from the Bavarian Prealps,
launched its first model exactly 25 years ago, and since then has been delighting
passionate music lovers and professionals alike. With its manufacturing facility on Lake Starnberg, Ultrasone has decisively shaped the production of dynamic high-end
headphones “Handmade in Germany”: the Edition series has earned the company
global renown. Today, hi-fi enthusiasts and audio professionals in over 50 countries
enjoy Ultrasone headphones. The company has successfully filed over 60 patents
that have been incorporated into numerous developments. They stand as a symbol
for our continuous research.

The Crowning Jewel of the Edition Series

Ultrasone now presents a new masterpiece from its manufacturing facility: the Jubilee Edition 25. Thanks to their matched titanium-coated, 40-millimeter Mylar drivers, these high-end closed headphones offer the ultimate audiophile experience. They provide a unique richness of detail, thus forming the foundations for the impressive resolution. At the same time, they form the basis for excellent spatial localization and precise depth graduation. Music is therefore reproduced exactly as the artist intended.

S-Logic EX Redefines Spatial Listening

When combined with the driver, one Ultrasone core technology ensures a musical
experience not normally found outside the concert hall: S-Logic EX is based on a
de-centrally positioned, angled sound transducer whose funnel-shaped housing
produces a much more spatial effect and greater transparency due to more frequent
signal reflections. The resulting sound experience is now virtually indistinguishable
from high-end speakers, but far outshines them in terms of audible details. S-Logic
EX creates a broad stereo platform and a vivid tonal depth gradation combined with
unrivalled detail of reproduction that turn both classical and modern music into a
unique experience.

Premium Materials Accentuate Exclusivity

The acoustic perfection of the Jubilee Edition 25 is impressively accentuated by an ensemble of premium materials: Ultrasone is setting new standards in headphone design, with ear cups made from Makassar ebony. This extremely exclusive, renewable raw material is finished by a specialist company based in Swabia, Germany. This precious wood, which has been coated in eight layers of piano lacquer, is then manually fine-sanded, polished and finally coated to protect the surface a further eight times – all to provide it with its final deep-gloss finish. The finely worked decorative inlay made of 925 sterling silver, which is accompanied by a
certificate providing proof of quality, emphasises the Jubilee Edition 25’s exclusive
appearance. The ear cushions and the cushioning on the aluminium headband
feature the dark-grey leather of the Ethiopian long-haired sheep, which provides an
attractive contrast to the colour of the wood grain.

Ready-Balanced Thanks to LEMO Connector

Even just connecting the Jubilee Edition 25 is a pure joy: the LEMO connectors snap securely into the ear caps and, together with a hand-selected, silver premium cable, provide a breathtaking musical experience. Thanks to the detachable cable and the standardised LEMO connector, it is possible to produce a tailor-made cable in any required length. This also provides the possibility of a balanced connection. Every Jubilee Edition 25 comes with a 3m cable for 3.5mm and 6.3 stereo jacks.

Unique Listening and Wearing Experience

Simply switch off, listen to the sound of your favourite music and relax – the true
virtues of a set of headphones are shaped not only by their sound quality, but above
all by their wear comfort and ergonomics. The headband and ear cushions on the
Jubilee Edition 25 are therefore covered with the fine leather of the Ethiopian longhaired
sheep. This soft material retains its silky properties for a lifetime, and yet is
extremely hard-wearing. The headphones sit perfectly with an optimal, gentle hold
thanks to the adjustable, cushioned headband. Weighing in at just 314 grams, these
headphones make it possible to enjoy music for hours on end. Furthermore, the
shielding conforms to the ULE standard, thereby guaranteeing fatigue-free

A Manufacturing Facility That Produces Unique Pieces

Each Jubilee Edition 25 is handmade in the ULTRASONE manufacturing facility on the Raucherberg Estate in the Bavarian Prealps. All the components undergo extensive quality checks before they are assembled to create a set of top-class headphones. In addition, precise matching of all sound-shaping components really ensures that the left and right sound channels sound the same and music lovers profit from the high-quality input to the full. After one last comprehensive quality check, each set of the 250 Jubilee Edition 25 headphones is given an individual serial number – making each pair visibly unique.

High-Quality Case for Safe Transport and Optimal Storage

Even though it is tempting to enjoy music on the Jubilee Edition 25 every minute of the day, safe storage and transport should still be guaranteed. That is why ULTRASONE provides a painstakingly crafted premium case with every model. The elegant hard case stores the headphones and their accessories and perfectly showcases the Jubilee Edition 25 even on the go.

ULTRASONE Jubilee Edition 25 will be available in stores from the end of November 2016.

Ultrasone Unveils Its Latest Masterpiece: The Edition 8 EX

Ultrasone's Edition 8 EX uses S-Logic® EX technology to make a big impression at home and on the go.

With the Edition 8, Ultrasone has created a piece of headphone history: No other handmade headphones have sold as well as the masterpiece manufactured in Bavaria.... Now, in 2016, some 8 years after the launch of the Edition 8, it is time for a successor that will once again inspire the segment it has created for itself: the Edition 8 EX. 

A new masterpiece is created through innovation and precision.

The mission of headphone developers is to continuously delight music lovers. But how do you improve upon a masterpiece? With innovation and precision. With the Edition 8 EX, Ultrasone introduces the first mid-size headphones with S-Logic® EX and balanced input. For hi-fidelity audio enjoyment at home and on the go. The centrepiece of the closed-ear headphones is a titanium-coated 40-millimeter Mylar sound transducer that reveals the unique audiophile properties through this exquisite material combination. All the fine details that facilitate balanced input are reproduced precisely. With a frequency range from 5 to 46000 Hz, the driver covers more than the range of human hearing. When fine-tuning the headphones, Ultrasone drew inspiration from its legendary predecessor and made musical enjoyment the priority.

S-Logic® EX redefines spatial listening with headphones.

The latest and most elaborate development in the history of S-Logic® was, up until now, Ultrasone’s flagship Edition 5 headphones. For the first time the Edition 8 EX offers impressive three-dimensional listening for closed mid-size headphones. S-Logic® EX is based on a peripherally positioned, funnel-shaped arrangement for the sound transducer, oriented downwards to the front, which results in a much more three-dimensional effect due to more frequent sound wave reflections. The resulting sound experience is now virtually indistinguishable from high-end speakers. The S-Logic® EX creates a broad stereo platform and a vivid tonal depth gradation that turn both classical and modern music into a unique experience.

Masculine design for a powerful sound statement.

Just for listening? No way! With its masculine lines, the Edition 8 EX is an elegant eye-catcher – whether it’s in use or not. The dark ceramic inlay with the fine laser engraved Ultrasone logo is impressively accentuated together with the high-gloss chrome-plated ear cups and the pale silver aluminium headband. A classic interplay of dark colors and matte silver that represents technique and passion. The dark grey leather of the ear cushions and on the top of the headband emphasizes the powerful design. And even the high-end cable has its part to play: it echoes the silver of the headband and thus continues the silver line from the headband to the exquisite high-end audio components.


Exquisite materials for excellent wear comfort.

High-gloss chrome-plated ear cups, Ethiopian long-haired sheep leather and an aluminium headband with ceramic inlays: the Edition 8 EX, made of fine, perfectly matched materials, stands for unique music-listening pleasure. All the materials also have something in common: they are extremely lightweight. The Edition 8 EX’s excellent wear comfort is largely due to the fact that it weighs only 330 grams. While the velvety leather caresses the skin, the new Edition rests almost imperceptibly on the wearer’s head. And there is one more thing that the materials used have in common: they all stand for a sustainable production philosophy and lasting enjoyment with the product.

Fine details: balanced input and magnetic ear cushions.

Perfection down to the very last detail: The Edition 8 EX impresses with its extremely precise build quality. One special detail: the ear cushions are connected to the cups by four strong magnets and can be removed easily by applying slight pressure. They are therefore easy to detach when necessary. The cable, designed for balanced operation, can be connected in no time and trouble-free with the professional four-pole LEMO connectors. The signal can thus reach the headphones optimally.

Hand-crafted in Bavaria

Every individual Ultrasone Edition 8 EX set of headphones is handmade at Ultrasone’s factory in Bavaria. Here, on the Raucherberg Estate, great care is taken to assemble each individual component to create an audiophile masterpiece. After manufacturing, every model is put through painstaking testing procedures in order to ensure that every music lover enjoys satisfaction with the Edition 8 EX. At the end of the meticulous manufacturing process the Edition 8 EX is given the final touch: every model is given an individual serial number, making it unique.

They will be available in stores from the beginning of November 2016.

Sound On Sound Reviews the LD Systems Curv 500 ES Compact Line Array

LD’s latest PA range combines the benefits of a line-source sound system with a flexible and modular design.

LD Systems’ new Curv 500 is a compact and lightweight (around 22 kg max) modular sound system, which can be purchased in three configurations for either mono or stereo applications. All follow a familiar format, with a powered sub feeding up to four compact, passive satellites. The smallest configuration comprises one sub feeding two satellites in stereo, and you can go up to a two-satellites-per-side stereo variant. We received the four-satellite, mono ‘ES’ (Entertainer Set) for review, which would be weil suited for solo/duo acts playing in bars, but also has other applications induding dance studios, schools or AV presentations. Although LD are a German company, Far Eastern manufacturing is used to maintain a competitive price.

A frequency response of 47 Hz to 20 kHz is specified, and the total system power is 460 Watts, producing a sound pressure level of 128 dB (peak; around 120 dB continuous level), making it suitable for small-scale, full-range applications or as a vocal PA for use in smaller venues. A rotary switch on the sub’s control panel configures the internal DSP to optimise the system for one, two or four satellites.

Each satellite locks to the next via a rugged sliding latch, which also carries the necessary electrical contacts; the lowest satellite locks to the top of a Smartlink adaptor for converting a Speakon feed to power the satellites above. This adaptor also indudes a pair of sockets for the induded pole mount, which fixes to the top of the sub. Which pole socket you use depends on how many satellite speakers you have, as they are set at two different angles.

In addition to the subwoofer/mixer and the satellites, our review system included one Smartlink adaptor, one speaker cable, an IEC mains cable and a mounting pole. With four satellites mounted together, the system takes on some of the character of a line array due to acoustic coupling between the speakers. This, in turn, changes the overall frequency response characteristics, hence the need to switch the sub feed to match the number of satellites.


The front face of each satellite measures only 12 cm square, but they are built into tough, powder-coated aluminium cases that slot together to form a gently curving array. Each satellite speaker houses a four-inch driver plus three one-inch tweeters; you can’t see them through the metal grille, but the three tweeters are arranged in a vertical line, and mounted in front of the four-inch driver. This driver arrangement is given the title of WaveAhead technology, and we’re told it achieves a dispersion of 110 degrees in the horizontal plane but only 10 degrees in the vertical plane (for an individual speaker). This is helpful in difficult spaces as it allows you to put the sound where it needs to be, rather than spraying half of it onto the ceiling and floor.

An included short cable connects one of the two satellite outputs from the sub to the base of the Smartlink adaptor; the sub’s left and right satellite outputs are on separate Speakon connectors, though only one is used in a mono setup. For fixed installations and desktop applications, a terminal block connector is provided on the back of the Smartlink adaptor.

Power for the satellites comes from the power pack in the sub (325 x 383 x 491 mm), which can drive up to four satellites in mono or two pairs of two in stereo. To expand the review system for two-plus-two stereo use would require only an additional Smartlink adaptor and a floor stand. The Smartlink adaptor has a proprietary pole-mount format and so won’t fit a Standard speaker stand.

The bass-reflex subwoofer is built around a 10-inch driver and uses DSP-controlled, Class-D power amplification to provide limiting, short-circuit protection, and to guard against overheating and over-voltage conditions. Power can be from 100 Volts to 240 Volts, and two audio connections are provided for the system output: a five-pin XLR socket to connect an additional Curv 500 SE subwoofer or the Curv 500 PES Power Expansion Set, and a three-pin XLR line output to allow expansion or integration into other sound systems. A ground-lift switch is fitted.

The sub is built into a plywood cabinet with three carry handles, and the controls are located on the top panel and the main connections are on the rear. A simple four-channel stereo mixer is built in and includes 16 digital effect presets as well as basic EQ, though there’s no channel panning. Audio can be streamed in from a mobile device via Bluetooth, which is useful for those needing backing tracks or interlude music. A mono switch on the mixer configures it for mono use when no second-channel speaker system is connected – as was the case for our review system. This sums all channels, effects and stereo inputs to mono.

‘Combi’ jack/XLR sockets handle the mic/line inputs for channels one and two, with channel three/four being arranged as a single stereo channel that can accept either left/right singles on separate ‘combi’ inputs, via an aux stereo mini-jack feed (wired in parallel with the main inputs) or a Bluetooth feed. lf you use an external mixer to handle more channels, it could feed into inputs 3/4 leaving you with two free mic channels. A button and LED facilitate Bluetooth pairing. Channels one and two have high and low shelving EQ controls plus a send to the effects section, and all channels have an input level control. The mono/stereo button is located at the bottom of channel 3/4, while a master control section provides a main level control, a sub level control, switching for one, two, three or four satellites, and a rotary selector for the preset effects. These comprise mainly reverbs, delays and combinations of the two, though there are a couple of options that also include chorus.


Setting up the system is easy enough, and the satellites lock together very firmly, so I’d be inclined to leave them joined and then store them in a foam-lined plastic toolbox or similar for protection while in transit. The curved array when four satellites are used means that you can set the speakers up fairly high yet still get good coverage at the front for those close to the speakers; the top speaker faces forward while the bottom one is angled down at around 30 degrees or so. I tested the system at a party, where several musical acts would be performing to around 70 guests, and the LD system, set up close to a corner, covered most of one room while an adjoining space was covered by one of my Schertler 150 Watt powered speakers.

Music retains rather more clarity than might be expected from a typical small PA system, with a clean mid-range, more-than-adequate bass weight and open-sounding highs. This characteristic carries over to vocals, delivering a very natural sound with none of that plastic-speaker ‘boxiness’ that sometimes intrudes. A miked cajon showed the subwoofer as being more than capable, and even when things got lively with the addition of electric guitars and electric piano, we always had plenty of vocal level, with fewer feedback worries than usual. The effects work weLl and deliver the kind of quality you might expect from a modest hardware reverb unit, though as we so often find in mixers of this type, many of the reverb presets have longer decay times than might be considered ideal. Even so, there are enough usable ones to add a suitable gloss to vocals without overdoing things.

A pair of these systems would probably hold their own in a band context for smaller gigs, but the Curv concept really shines when handling more discerning material at a moderate level. It sounds great on acoustic guitar and vocals, keyboards come over cleanly, and while the lows might not challenge those of an 18-inch sub, there’s still plenty of depth for most applications without the system sounding strained. For duo and trio bar gigs where you need an almost hi-fi sound, a stereo setup with two satellites per side would probably be the best option, while this mono system might be a more practical choice for performing in a tight space or for other mobile applications, such as dance classes or presentations.

Given its build quality, portability and sound quality, the cost of the system makes it very attractive, especially if you need something that’s easy to carry and set up.

• Lightweight and compact
• Clean, well-balanced sound
• Directs the sound where you need it
• Built-in mixer and effects

• Nothing obvious

This is a well thought-out system that allows you to buy the mono or stereo configuration that best meets your needs. It is well suited to high-quality, moderate-volume bar gigs and suchlike.
