DAW Auto-Mapping & Performance Control Thanks to the OLED screen that sits front and center, it’s easier than ever to search for and test sounds, map controls, and mix & edit your sessions. Hammer 88 Pro can control any DAW and automatically map commonly used functions such as Transport, Faders, Pan controls and much more! Whether you use Pro Tools, MPC Beats, Cubase, Logic, Studio One or any other major DAW, just select the map and Auto-Mapping will take care of the rest! It also instantly maps to all the virtual instruments included in the Hammer 88 Pro software bundle (Hybrid, Velvet, Mini Grand, Xpand!2, Vacuum, Boom, and DB33). These world-class AIR Music Tech plugins can be fully controlled by the Hammer 88 Pro and used in real-time as you create and mix your music. Smart Controls Hammer 88 Pro features M-Audio’s brand-new Smart Chord and Smart Scale technology. These functions open up your imagination and help blend your hardware seamlessly with your ideas across all 88 keys. Creating music on your computer has never been this intuitive and inspiring thanks to these workflow-centric features. With Smart Chord activated, pressing a single key or pad will play a full chord rather than just one note. The key or pad you press will determine the root note in the chord. The rest of the chord’s properties (major, minor, etc) are determined by the settings you choose. Smart Chord also has a Custom Mode that lets you determine the chord structure that will be assigned to each key by manually playing it. For example, if you select Custom Mode, and play a 1-b3-5-b7 chord, every key will then be assigned to play this chord structure. The note of the key you press will serve as the root of the chord and all of the parameters can be edited right on the Hammer 88 Pro! Smart Scale technology allows you to set the keybed so that only notes in the selected scale are able to be played. This allows you to play within a chosen scale without the risk of playing any “wrong” notes. You can choose from 16 different scale variations when assigning a scale to the keyboard. Smart Scale is easy to activate and deactivate and allows you to set the scale parameters you need to keep you focused on creating. Professional Controls Built into the Hammer 88 Pro are features that are essential to creating modern pop, electronic, hip hop, and dance music. Note Repeat and the built-in Arpeggiator open up a world of precise music production and live sound techniques to make your music sound professional. Note Repeat allows you to hold down any of the custom-made M-Audio performance pads and hear a repeated rhythmic pattern at a selectable note division. The Note Repeat feature can be activated momentarily or can be used in Latch mode. If you choose Momentary, holding the Note Repeat button will make the note played by the pad automatically repeat. If you choose Latch, pressing any pad will cause its assigned note to repeat without you having to hold down the Note Repeat button. The built-in Arpeggiator will affect anything you are playing on the keys from any virtual instrument in your DAW. When the Arpeggiator is activated, the keyboard will repeatedly play the pressed keys in sequence. The arpeggiator’s timing and rhythm is based on the keyboard’s time division setting and either the keyboard’s or your DAW’s tempo setting. Each note in the arpeggio will be the length you’ve selected for the time division setting; for example, if you select 1/4, each note in the arpeggio will be a quarter note. This powerful tool can operate in Latch or Momentary mode, making it easy to match your style. Next-Gen Piano Feel Hammer 88 Pro’s best-in-class 88 graded hammer-action keybed combines professional, graded, weighted hammer-action with advanced high-speed keybed scanning technology for an ultra-expressive playing experience. This custom keybed also features Channel Aftertouch, giving users added expression and control. Channel Aftertouch enables you to affect the sound of a virtual instrument plugin by continuously scanning how much pressure you apply to any key after initially pressing it. This makes creating the mood, dynamics and emotion you want to deliver in your music natural and fast.

Designed from the ground up for network audio Typical IT network switches/routers are designed with the sole purpose of taking data from A to B with a noise floor and precision that is "enough" for the rate of transmission. This is fine for data networks but when sensitive components such as DACs and Pre-Amplifiers are involved, it will have an audible impact on sound quality The PhoenixNET is the realization of Innuos' philosophy of simplicity and signal purity applied to the network switch. Having started with improvements to the Ethernet ports' clock on our flagship Statement, Innuos has now taken the concept to the next level with a completely new network switch design that focuses exclusively on audio use. Design is focused on 4 areas: Noise, Clock, Power and Vibration. Minimise Network Switch Noise Simpler 100mbps network switch chip results in lower operating noise floor compared to Gigabit Network switch chip with no internal switching regulators. All 3 independent voltages supplied by internal Statement-grade linear power supply with independent ultra-low noise regulation. Massive individual Network Isolation Transformers to further isolate from noise coming from router or connected devices Just the right amount of Individually shielded, high quality ethernet ports soldered directly to the board with no ethernet activity lights as blinking leds introduce considerable electrical noise. EMI absorption at the right places so that interference produced can be captured before influencing other components. Increase Clocking Precision and Stability Using the same 3ppb 25MHz OCXO oscillator as used in the Statement, individually powered by its own linear power supply and connected directly to the network switch chip, avoiding precision losses from using external master clocks. Provide Pristine Power to the Components 2 independent Statement-grade linear power supplies with Mundorf Caps to power individually the OCXO clock and the mainboard, keeping the power path short with less opportunity for EMI contamination. Minimise Vibration on Components Vibration was managed at 3 levels: Anti-Vibration feet tuned to the resonant frequency of the chassis, top cover treatment to convert vibration captured from sound waves into small amounts of heat and sturdy RJ45 ports with silicone connection to the chassis.
The new WA-MBA professional broadcast boom arm from Warm Audio adds the finishing touch to your broadcast or streaming setup, allowing you to properly position your microphone for ultimate sound quality.

XT40i with X-Tube™ Technology As befits a company rapidly closing in on its fifth decades at the forefront of speaker cable design, QED’s brand new XT40i speaker cable builds on the formidable reputation of the XT40 cable it replaces and offers a decisive step up in sound quality.This pure oxygen-free copper cable uses an evolution of QED’s established X-Tube technology to guarantee superb timing and stereo imaging, and adds the brand new and highly innovative Air Gap dielectric to bring unheard-of rhythmic accuracy and musicality to a cable of this modest price. Very low DC resistance adds unrivalled frequency response to XT40i’s already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.We urge you to audition XT40i - we’re confident you’ll agree it even outperforms alternative cables at many times the price. Prepare to be surprised and delighted. Air Gap dielectric By increasing the separation of the conductors inside the cable, and therefore the amount of air between them, QED has created a low-loss Air Gap dielectric. This technology halves the dissipation and capacitance characteristics of the cable, and results in numerous audible improvements - particularly where timing and rhythmic accuracy are concerned. Despite this increased separation, though, XT40i retains the sort of cross-sectional area that makes it ideal for long cable runs. X-Tube technology Forming the cable conductors into a tube-like shape around a hollow insulating rod in the centre of the cable equalises current densities, delivers very low inductance and presents a consistent, even load to an amplifier. The result is a cable that retains more of the finest musical details, that handles rhythms and tempos in the most natural and musically satisfying way, and that outperforms rival designs costing far more. Specification: Outside diameter: 6 x 14 mm Conductor area: 4 mm² Dielectric properties: Air Gap (εr = 2.4) Conductor chemistry: 99.999% oxygen-free copper Dielectric properties: Air Gap Loop resistance: 8.0 mΩ/m Parallel capacitance: 35 pF/m Dissipation factor @ 10kHz: 0.0295 Self-inductance: 0.57 μH/m Gauge: 12 AWG
The SNAIC family of interconnects use a cable which is custom manufactured to our specification to provide the ideal impedance, capacitance and conductivity for Naim Audio products. Each SNAIC interconnect is meticulously hand-built in-house using established production techniques.
During the development of the reference CD555 CD player, a special project ran in parallel; to develop a new signal cable that would exceed the performance our standard signal cable. The brief was to investigate all parameters of a signal carrier; to improve the whole rather than just improving the cable as is the more normal development practice. The result of this pure development project is the Hi-Line signal cable. Available with both DIN and RCA terminations, its patented Air-PLUG connector is a decoupling device that reduces vibration transmitted along the cable itself, preserving your system’s precious musicality. Features Patented Air-PLUG decoupling mechanism prevents vibration transmission through the cable Twisted-pair cable construction consisting of 80 litz conductors surrounded by individual spiral shielding layers of PTFE and Kapton RCA or DIN terminations available, plus DIN-to-RCA if needed Technology & Craft The Hi-Line Air-PLUG (patented) is designed as a decoupling device to minimise microphonic interference and preserve the integrity of the audio signal. The many different rear sections of the Air-PLUG are clipped together to form a lossy flexible section. The cable is clamped compliantly to the end of this flexible section. The cable itself was also carefully designed to preserve audio signal integrity so improving sound quality. It is manufactured from twisted pairs of 80 Litz conductors surrounded by PTFE, Kapton and PTFE tape all then enclosed within a semi conductive shield to reduce static charges. This is then wrapped by two spiral wound copper shields and lapped PTFE tape. Two of these assemblies side by side are then wrapped in layers of PTFE tape and finally a rubber outer covering. This gives a two-channel cable where the signal and RF grounds are held in a static position relative to each other negating any difference in field between them.

Very low DC resistance adds unrivalled frequency response to XT40i’s already potent audio capability. The result is a cable that advances on the class-leading standards set by its predecessor.We urge you to audition XT40i - we’re confident you’ll agree it even outperforms alternative cables at many times the price. Prepare to be surprised and delighted. Air Gap dielectric By increasing the separation of the conductors inside the cable, and therefore the amount of air between them, QED has created a low-loss Air Gap dielectric. This technology halves the dissipation and capacitance characteristics of the cable, and results in numerous audible improvements - particularly where timing and rhythmic accuracy are concerned. Despite this increased separation, though, XT40i retains the sort of cross-sectional area that makes it ideal for long cable runs. X-Tube technology Forming the cable conductors into a tube-like shape around a hollow insulating rod in the centre of the cable equalises current densities, delivers very low inductance and presents a consistent, even load to an amplifier. The result is a cable that retains more of the finest musical details, that handles rhythms and tempos in the most natural and musically satisfying way, and that outperforms rival designs costing far more. Specification: Outside diameter: 6 x 14 mm Conductor area: 4 mm² Dielectric properties: Air Gap (εr = 2.4) Conductor chemistry: 99.999% oxygen-free copper Dielectric properties: Air Gap Loop resistance: 8.0 mΩ/m Parallel capacitance: 35 pF/m Dissipation factor @ 10kHz: 0.0295 Self-inductance: 0.57 μH/m Gauge: 12 AWG

The powerhouse model of the Wharfedale DIAMOND 12 series, the DIAMOND 12.4 is the room-filling, chest-pounding, largest model in the series. For larger, more powerful systems and cinema-style home theatre experiences, the DIAMOND 12.4 will fill your room with an impactful, immersive performance. Configured in a 2.5 way system with exception crossover technology, the DIAMOND 12.3 utilises dual 150mm (6.5”) KlarityTM drivers for impactful yet refined mid-range and bass frequencies, while the 25mm (1”) dome tweeter delivers open and smoothly extended high frequencies. A voice coil beyond this class The voice coil is wound on a high-power epoxy/glass fibre bobbin highly unusual in speakers at this price level. This has the advantage of not adding eddy currents and delivering greater power handling than an aluminium bobbin, whilst also being much stiffer than the Kapton type associated with this price-class. DIAMOND highs The 25mm dome is made from a woven polyester film with a high-loss coating to deliver open and smoothly extended high frequencies. The magnet system and the front plate have been optimised for wide dispersion and uncompressed behaviour. The front plate is flat and exposes the dome as much as possible; only a very short duct on the front plate balances the acoustic load and improves the SPL (sound pressure level) measurement. A crossover of style The crossover network uses an acoustic LKR 24dB topology. This includes air-core inductors of the type more commonly found in high-end speakers, selected because they produce the lowest distortion of all inductor types. As the resistance of the coil is higher than a standard laminated steel or ferrite core inductor, the magnetic structure of the mid/bass driver has been modified to compensate, resulting in fast, clean bass with no distortion from the inductor. Firm and fair The DIAMOND 12.1 ’s rear-ported enclosure is precisely sized so that the internal volume works in harmony with the drive unit system to deliver the desired sonic result. A multi-layered sandwich design subdues the identifiable characteristics of the cabinet’s ‘sound’. Even the resonant properties of the glue between the layers was measured to determine the optimum combination. Brace yourself Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a specific form of the wood brace to achieve an optimal reduction of cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the commonplace ‘figure of eight’ brace, which may simply transfer resonance from one wall to another.

The journey to XT25..... The QED speaker cable story began in 1973, with the launch of the world's first specialist speaker cables, QED 42 and 79 strand, now household names in the audio industry. Building on this longstanding British speaker cable heritage, QED embarked on an exhaustive research program into cable parameters which began in 1995 and continues into 2017 with the release of “The Sound of Science”, a 40 page White Paper distilling the research published since 1973 by QED. These reports set out the “top down” design-principles that have resulted most recently in the development of QED XT25 loudspeaker cable – the new class leading standard in budget to mid-range speaker cables. What are the features which make this cable so special? X-Tube™ technology first came to prominence in 2005 with the launch of the world renowned Silver Anniversary XT, the most highly regarded mid-range cable in the world, winning the What Hi-Fi Product of the Year three years in a row. These design principles also grace the multiple award winning XT40 speaker cable and XT25. As frequency increases, electrons flow more and more towards the periphery of a conductor so that if the frequency is high enough only a very thin layer (or skin) on the outside of the conductor is used. This “skin depth” varies for different materials at a fixed frequency and in copper it means that if a conductor has larger than 0.66 mm² cross-sectional area not all of that area is available for an analogue music signal to use. In SAXT the “skin effect” problem was effectively eliminated by the use of X-Tube™ Technology which works by placing all of the conducting material around a central hollow insulating rod. However, for a.c. signals, changing magnetic fields generated by the flow of current set up eddy currents in nearby conductors which force current to flow only in areas furthest away from conductors carrying current in the same direction and vice versa. This “proximity effect” has a detrimental influence on current distribution in a speaker cable even if it utilises X-Tube™ Technology. With XT25 we tackle the proximity effect and the skin effect by combining our existing Aircore™ and X-Tube™ Technologies into a new X-Tube™ variation. By forming the conductors into a tube-like shape with a hollow centre, current densities at higher frequencies are maintained because the electric field which contributes towards the skin effect acts towards the centre of the conductor from where the conductive material has been removed. At the same time instead of using a braided structure a ring of conductors is formed into separate bundles with only a loose electrical association which are then twisted into a 90 mm lay so that no single conductor bundle remains on the inside or outside of the cable (and therefore prey to the proximity effect) for long enough for it to become an audible problem. This geometry promotes a more consistent signal distribution making for a more accurate musical reproduction. Low DC Resistance At QED we recognise that low d.c. resistance of the loudspeaker cable is of paramount importance for high-fidelity signal transfer. This is because the speaker presents a frequency dependent load to the amplifier of which the cable forms a variable proportion. If resistance is allowed to be too large then audible changes to the frequency response characteristics of the loudspeaker will be introduced which cannot be corrected for by the amplifier’s negative feedback loop. In order to provide a marked improvement over similarly priced cables in both our own and our competitors’ ranges without increasing the overall size and flexibility of the cable substantially, the cross-sectional area (CSA) of XT25 has been enlarged to 2.5mm2 of 99.999% oxygen-free copper. This instantly gives the new cable a low d.c. resistance and therefore a more accurate musical delivery. Low-Loss Dielectric It is not generally appreciated that the electrical signals moving at or near the speed of light in a wire do so via the medium of electromagnetic (EM) waveforms which exist within the dielectric which surrounds the conductors as well as within the conductors themselves. The movement of electrons along the conductor merely facilitates generation of the EM waveform as their “drift velocity” is only a few centimetres per second. It is therefore important to ensure that the dielectric material used to insulate and protect the central conductors of the speaker cable is of a type which “permits” the establishment of EM waveforms without appreciable loss. Dielectric losses are directly proportional to the “permittivity” of the material used and as this a measure of each material relative to that in a vacuum it should be as close to unity as possible. Like its predecessors, XT25 uses a specially formulated low-density polyethylene (LDPE) dielectric which at 1.69 has the lowest relative permittivity practically available. QED research has shown that low capacitance cables are generally preferred in listening tests over high capacitance counterparts and this is usually because low-loss dielectrics have been utilised. The use of LDPE and careful control of conductor spacing results in a cable with a very low capacitance per meter and a dissipation factor (loss tangent) of 0.0001 at 10 kHz. What is the result of all these techniques? The graph below shows how the dc resistance of XT25 remains effectively unchanged across the entire audible frequency band when compared to a conventional cable of the same cross-sectional area. Combined with the sonic advantages of a low loss dielectric the improvements in current distribution place the new cable in a class well above cables with a less sophisticated geometry. What makes XT25 unique? 1. Award winning heritage guaranteed All QED cables are designed using the top down principle. XT25 represents the core musical performance trickled down from our money-no-object Supremus cable in a more affordable package. QED has won more What Hi-fi? Awards than any other single brand and with XT25 this heritage is delivered at a sensible price. Unlike most other manufacturers, QED offer an unlimited lifetime guarantee which means that if your cable ever fails to deliver to its full potential during its lifetime we will replace it free of charge. 2. X-Tube™ Technology....but with a twist In loudspeaker cables high pitched sounds are forced to travel towards the outside of the conductor and so are able to use less and less of the available cross-sectional area as the pitch increases. This is called the “Skin Effect”. It means that for high frequencies the resistance of the cable appears to be much higher than it does for lower pitched sounds. Eddy currents in one conductor can affect the current flowing in an adjacent conductor so that currents flowing in the same direction move away from each other. This “Proximity Effect” also increases resistance as frequency increases. These phenomena have a detrimental effect on the fidelity of the sound you hear. The XT25 variation of QED X-Tu Insulation LDPE jacket with 100% coverage of Aluminium Mylar tape wrap Plugs and spades QED Airloc™ Forte banana plugsbe™ Technology solves these problems by creating a hollow tubular conductor geometry out of individual conductor bunches through which each frequency can pass with equal ease when compared to traditional solid or stranded conductors. 3. Low-Loss Dielectric Music signals in a loudspeaker cable move back and forth many times every second. The insulating material used to separate the send and return conductors from each other (the dielectric) has to be charged and discharged every time. Not all of the energy stored in the dielectric during each charge cycle is completely returned during each discharge cycle which has a detrimental effect on the fidelity of the sound you hear. That’s why at QED we use low-loss dielectric materials such as Polyethylene (PE) or Teflon™ (PTFE) in preference to cheaper PVC alternatives found in inferior unbranded cables. 4. 99.999% Oxygen-Free Copper Speaker cables need to have a large current carrying capacity. If the electrical resistance of the cable is too large, part of the music signal will be lost, causing a detrimental effect on the fidelity of the sound you hear. To stop this from happening we make the resistance of our speaker cables as small as possible. We do this by using the largest practical cross-sectional area of copper within the size constraints of each cable. In order to squeeze the last drop of performance from the conductors we make sure that there are no impurities in the copper which would defeat the object of making them so large. That’s why we use 99.999% oxygen-free copper exclusively. 5. Just Listen Unique proprietary technology and trademarked geometries plus our award winning heritage all combine to create audible sonic improvements when compared to other loudspeaker cables. Ask your dealer for an audition – he will be happy to let you hear the difference.
