Total Production


September 2007

September's PLASA trade show, which annually draws international crowds to London's Earls Court, will take on a new layout and occupy two halls for the first time.

This year's show at Earl's Court will feature the hotly anticipated debut for PLASA Events, a new division of the Association, which foresees record exhibitor and visitor numbers over September 9-12.

The industry's leading manufacturers will use PLASA07 as the launch pad for their latest technologies, including new developments in lighting, analogue and digital audio, video, special effects, staging and rigging products.

The show's new single-floor layout — which gives the show plenty of room for future growth — has made it possible to create more quiet and comfortable seating areas in Earls Court 2, including a wi-fi zone, for meetings and socialising.

A dedicated fast-track entrance will be provided for pre-registered visitors (tickets can still be bought on the day from the usual registration area at the front of Earls Court 1), as well as four PLASA Theatres, which will host four days of exclusive seminars, training sessions and workshops. These Theatres are located on the main show floor in Earls Court 2, divided into official 'special interest' seminar theatre sessions and exhibitor-led sessions.

With its broadest agenda in the show's history, the PLASA07 educational programme will give attendees access to some of the most knowledgeable practitioners in the industry. Last year's guest presenters Technologies for Worship and InfoComm International return with an expanded seminar programme, while Cast Software will host a series of visualisation training sessions.

The four-day Special Interest Seminars programme includes sessions from InfoComm International and the British Entertainment Industry Radio Group (BEIRG). It is designed to offer attendees an update on current industry issues, as well as valuable knowledge that can be applied in the workplace.

Several theatres have recently announced their intention to become carbon neutral, so Monday will see a special presentation from The Theatres Trust, assessing how venues can do more to become carbon neutral theatres. On Tuesday, BEIRG presents Digital Dividend Review: The Consequences, an update on the status of this crucial issue which has brought the industry together to fight to save the radio frequencies it relies on.

Tuesday also sees InfoComm Academy's Design School present Using Displays In A Staging Environment (understanding image brightness level essentials), aimed at all presentation professionals, whilst on Wednesday, InfoComm returns to present Ethernet Usage For AV & Staging, addressing the uses of Cat-5/6 cabling in a staging environment.

Leading the charge among the exhibitor-led sessions is Wireless Solutions whose team present Wireless Control Technology on Monday, followed later in the day by Acrobatic Rigging At Cirque du Soleil, hosted by Cirque du Soleil's technical director for Dralion and the chief rigger for Kà.

On Tuesday, Dr. Evert Start of Duran Audio’s R&D team will host a presentation entitled Modern Loudspeaker Array Theories & Technologies. The seminar will cover the basic physics of loudspeaker arrays and show how the directivity of loudspeaker arrays can be altered using ‘beam steering’ or digital directivity technologies.

Dr. Start will also investigate how these technologies can help achieve high levels of speech intelligibility and music clarity in even the most difficult of acoustic spaces and also how the technologies can be used to gain directivity at low frequencies. The theory and technologies discussed can be applied to both the worlds of commercial audio and sound reinforcement.

These are just part of a wider programme, full details of which can be found on the PLASA07 website at


Earls Court 2 will host the first public assessment sessions for the newly-launched National Rigging Certificate, which officially goes 'live' at PLASA07 following a successful pilot run this spring.

The redesigned Innovation Gallery, where the products nominated for the 2007 PLASA Awards for Innovation will be on display, has become a special feature of the walkways connecting Earls Court 1 and 2, with the Awards presentation at the Central Bar open to all visitors and exhibitors at 6pm on the Monday. These Awards recognise the best design and development work going on across the industry.

The PLASA Central Bar, at the heart of the show in Earls Court 1, will stay open until 8pm on the Sunday, Monday and Tuesday after the exhibition floor closes, giving everyone a chance to socialise without having to leave the show floor.

PLASA's director of events, Nicola Rowland, commented: "The buzz in the build-up to PLASA07 is tremendous and we are confident this will be the most exciting year yet in the PLASA Show's 30-year history."

We’ve already covered Lab.gruppen’s big product launch in our news section, but the Swedes aren’t the only company that’s showcasing significant new amplifier technology.

Yamaha’s line-up of power amplifiers is extended at PLASA by the launch of its new flagship TXn Series consisting of three high power models, the TX6n, TX5n and TX4n. Delivering 2200W, 2500W and 3000W respectively at 2 ohms, each model offers sophisticated onboard DSP, an area in which Yamaha quality is legendary. All three TXn models incorporate a sophisticated 24-bit 96-kHz DSP engine that delivers an extraordinary range of control and processing capabilities.
