overall system setup, but this is dependent on speaker manufacturers making this information available – or even having access to it in the first place. Amplifiers not tied in to a specific manufacturer’s speaker systems must establish new methods of making their designs both more intelligent and less complex to configure. It’s a tricky balance!” From next month, Yamaha’s CL series
of digital mixing consoles and Nexo’s powered TD controllers will use the new Yamaha-Nexo NXDT104 Dante network card to advance the integration and control of the NXAMP via the consoles’ touchscreen displays. The integration allows NXAMP discovery and patching operations that hitherto needed a computer running the Dante Controller software application. According to Yoshi Tsugawa, CEO of
Nexo: “We intend to take all operations and processes that are troublesome, time-consuming, complex or uncertain and make them fast, easy, assured and safe. This development marks another step in that direction.” Such pooling of resources is able to
take advantage of several evolutionary steps that seem to come together beneath the hood of the 21st century power amplifier. “Class D technology and its variants is now mature and established in the pro-audio market,” explains Joseph Carcopino, “so we’re seeing young engineers brought up with this knowledge and building the next generation with a power efficiency unimaginable a few years ago. The power electronics industry also has new components, with new materials, that solve some of the historical pitfalls with standard components.
CRASH TEST DUMMIES
One of QSC Audio’s ‘Testing The Limits’ videos has founder Pat Quilter firing bullets into a PLX2 (pictured). An exaggeration? Watch the video at
www.qscaudio.com/media. “We also offer a video – throwing an LX amplifier out of the window,” claims Dynacord’s Martin Traut. “It’s a bad joke, but the amplifier survived…” As for
Lab.gruppen: “We have examples of our amplifiers falling off a truck on the highway and still working,” states Klas Dalbjorn. “No one would expect an amplifier designed for touring to fall to pieces the first time a rack gets dropped,” points out the more sanguine Waring Hayes of XTA-MC2. “In many ways, the lightweight advantages of switching amplifiers go a long way towards self-preservation. We pot all coils and transformers, and ensure heatsinks are ‘sandwiched’ between the chassis and the top cover to reduce mechanical stresses on the output devices. They have enough to deal with!”
FULL & WIDE SOUND EXACTLY WHERE IT’S REQUIRED
“End users will decide who makes the toughest amp on the market,” admits Luca Giorgi of Powersoft. “What we can say is that we’re trying to focus our design on the power supply. This, in our view, is the more sensitive part of a touring amp in terms of reliability. Mechanical stress is an issue, but 90% of problems are related to the mains conditions you find during your performance.” And a final, salient point from
Nexo’s Joseph Carcapino: “Add a good economic crisis on top of increasing technology complexity, and you can see how tough we have to be…”
Just 300mm deep, the SL Series can be installed against a wall or in it...dramatically reducing the venue floorspace required.
The new KV2 SL412 and SL2.15 speakers incorporate an eye-catching, slim and stylish cabinet design. Using KV2’s VHD technology, the SL412 loudspeaker utilises 4 x 12” low mid-range components with a single 8” mid-range and 3” large format NPVD compression driver. The cabinet’s configuration keeps low mid frequencies in a controlled pattern, greatly reducing problem room resonances. Cabinets can be designed and supplied with custom colors, grill templates and logos, offering a flexible and true designer-integrated product.
The system is driven by proprietary KV2 amplification. The KV2 SL3000 powers a pair of SL412s and the VHD3200 which can drive up to four SL2.15 subs. SL Series - The Ultimate Club System

“In the end, the democratisation of computing resources and industrial CPU has made signal processing part of the game. So my feeling is that the ‘one-guy’ amplifier companies that were very common in the early years of this industry will have difficulties competing with companies that have an overall knowledge of power electronics, signal processing, industrial converters, isolators and so on. And I think that our [Yamaha-Nexo] combined knowledge between speakers, amplifiers and signal processors puts us in a good position for the future.” “Crown is in a good spot for the
future,” chimes Brian Pickowitz. “We have DriveCore technology that will help us achieve higher power, more efficient amplifiers with less weight. Combine that with the synergies at Harman in signal processing and loudspeaker design and you’ll see complete system packages that exceed the expectations of not only our customers, but their customers as well.” And so it is in the engine rooms of
pro audio: brands are ganging together to push their weight around. n
