KV2 Audio partners with RADA to offer training opportunities for sound students
UK – KV2 Audio has announced a partnership with RADA (Royal Academy of Dramatic Art) to support the training of young students in theatre sound production. KV2 has provided a range of EX Series loudspeakers to equip RADA’s Jerwood Vanbrugh and Gielgud theatres, and will also offer masterclasses on sound design and the use of point source technology in a theatre environment.
RADA’s head of sound, Steve Mayo, is delighted that KV2 has chosen to become a RADA in-kind partner. “These partnerships are the life-blood of hands-on training for our students,” he declares. “I am very eager for our sound students to have the opportunity, not only to work with high quality, modern equipment, but also to meet the people behind it. “The support we’ve had from KV2 has been invaluable in paving the way for this partnership, from our initial conversations at ABTT in June through to them organising for all our students to have a proper demo of the full KV2 range at PLASA last month.”
Mayo recalls that his decision to approach KV2 was sparked initially by well-known theatre sound designer, Richard Brooker, when he came in to talk to the students about working on musicals and mentioned that KV2 had become an important part of his designs. He was further prompted by the fact that Autograph Sound (with whom RADA already has a close relationship) are an important KV2 user, a fact endorsed by Autograph sound designer, Avgoustas Psillas: “We were lucky enough to get Avgoustos in to mentor to our sound design students when we were preparing for our musical production during the last summer term, and he was very complimentary about KV2, just as Richard Brooker had been. I was able to meet Tom Weldon from KV2 at ABTT for an initial conversation and arrange a visit for him to RADA so that he could see for himself the level and quality of training we offer our students.”
Following the visit, Weldon had no hesitation in agreeing to the partnership. “We’re very keen to work with the technicians, engineers and designers of the future and feel that we can contribute to offering them a solid grounding in modern theatre techniques with equipment that is actually in use in productions across the West End and Broadway as well as on national tours. We’re proud to be able to make a positive contribution to the education of future generations.”
Mayo wholeheartedly agrees: “RADA does an amazing job in terms of the amount of productions we do,” he explains. “Over the course of this academic year we will mount thirteen RADA productions across three venues as part of the Technical Theatre and Stage Management course in collaboration with the third year actors training. The partnership with KV2 hugely improves our FOH systems for both the Jerwood Vanbrugh Theatre and the Gielgud Theatre and is incredibly exciting for the students and the productions to be using state-of-the-art equipment for their learning.”

L-Acoustics Spotlights AVB Networking at AES
USA - The AES Convention’s technical programme has long been praised by seasoned audio professionals and students alike for its rich schedule of educational and training seminars offered at each gathering. This month, at the 147th convention and exhibition held at NYC’s Javits Center, L-Acoustics team members will be leading and/or participating in seven AES presentations, several of which will focus heavily on AVB (audio video bridging) networking and newly Milan-certified solutions, including the L-Acoustics P1 processor.
The first event, presented in room 1E13 at 9:00am on Wednesday, 16 October, will be a networked audio track panel session titled, “Solution-Based Approaches for Networked Audio in Live Production.” Moderated by Sound & Communications editor Dan Ferrisi, L-Acoustics director of electronics Genio Kronauer, one of the most recent members of the Avnu Alliance board of directors, and fellow panelists from Meyer Sound, Solotech, and other companies will share “how to” tips on working with Milan and AVB networking and practical use-cases from end users implementing Milan in live sound projects.
Kronauer will also participate in an Avnu Alliance-led session on 16 October for the Live Production Stage, starting at 2pm (LS04), titled “Milan Protocol: Deterministic AV Networks,” sharing an overview of the Milan product philosophy and benefits for the market, as well as case studies of live sound installations using a Milan network.
That same day, at 1:30pm in room 1E12, L-Acoustics product manager Scott Sugden will deliver a sound reinforcement track event titled, “Large-Scale Loudspeaker System Calibration from Simulation-Based Design to On Site Tuning.” The presentation will cover, among other things, the efficient implementation of the manufacturer’s Soundvision Autosolver tools, the benefits of Milan-compliant AVB networking as offered by P1, and the brand new M1 measurement platform, part of the upcoming LA Network Manager 3.0 release.
In the year since its debut, the multifunctional P1 AVB processor and measurement platform has firmly established itself as an indispensable tool for many audio pros. Designed from the very start to be compliant with Avnu Alliance’s new Milan interoperability protocol, P1 became one of the very first two products on the market to officially receive Milan certification through Avnu Alliance as a fully compliant Milan device earlier this year.
“Milan represents the pro AV industry coming together to define common protocols and ensure seamless interoperability between products, regardless of their brand,” says Kronauer. “What L-Acoustics and our fellow industry-leading manufacturers did with Milan was to take IEEE’s open AVB standard to a truly reliable and convenient ‘plug-and-play’ level, you simply connect a device and it works every time. This allows our users to focus on what they do best, which is creating amazing audio-video experiences for their clients and audiences.”
Designed to optimally deal with the real-time needs of professional media transport, Milan is a standards-based, user-driven deterministic network protocol that takes into account the specific needs of the pro AV market for moving time-sensitive, high-quality audio, video, and data across the network. Once network connectivity is established, Milan reserves bandwidth specifically for deterministic delivery, which ensures that users will never have a dropout or loss of information during a show or live performance.
Over the past year, numerous audio professionals have already enjoyed Milan’s benefits that the L-Acoustics P1 has provided, including tours for Hugh Jackman, Mark Knopfler, Madness, and Rammstein, as well high-profile installations at the Wells Fargo Center (home to the Philadelphia 76ers) and the iconic Hollywood Bowl.
According to Hollywood Bowl principal mixer and sound designer Fred Vogler, “There's a different show here almost every night and we have to stay on top of it every time. The Milan processors are easy to use and have a fidelity and a resolution that is really high. I've heard other types of digital transmission – we had AES in here – and it seems like the AVB Milan protocol is cleaner with enhanced fidelity, which makes it sound more natural. Also, in discussion with tours and other sound design folks that come through, we never get any pushback. We have to rely on it daily and alter or change it if necessary, so it is comforting to know that it's easy to use, has a great sound, and is something that, industry-wide, people are comfortable using.”
As a founding member of the Milan initiative, L-Acoustics has been able to build Milan into all of its amplified controllers and audio processors, concurrent with the development of the Milan standard.
The P1 processor is a unique, three-in-one unit that serves as a front-end processor, an audio matrix and bridge, as well as a system measurement and tuning platform, all in one convenient, robust package. The P1 takes the complex and hardware-intensive task of system optimization and streamlines it to a single piece of hardware, fully integrated with the industry-leading LA Network Manager software platform.
As a signal processor with equalisation, delay, and dynamics, its four analogue line inputs with premium A/D conversion assure the utmost sound quality. Integrating 20 inputs and 16 outputs in one rack space, the P1 can matrix, bridge, and distribute AVB, AES/EBU and analogue audio. Time-aligned redundant signal distribution guarantees artefact-free sound with the click of a button.
Updates to LA Network Manager will leverage P1’s four microphone preamps to create an analyzer that is aware of all system parameters. This technology enables system tuning without additional noise.
