Live Sound Seminar Details

Saturday, May 9, 10:30 — 13:00

LS1 - Neumann & Müller and d & b

Stefan Goertz
Michael Kennedy

Sound System Design and Commissioning in Critical Acoustic Environments

The interaction of sound systems with special attention to the excitation of diffuse sound will be examined in theory and practical demonstrations using speech intelligibility measurements as an indicator. Software-aided line and subwoofer array designs will be discussed followed by a live demonstration of the tuning and
alignment process.

Saturday, May 9, 15:00 — 18:30

LS2 - Sennheiser & Yamaha – Live Sound Workshop

Svenja Dunkel
Horst Hartmann
Oliver Voges
Jürgen Wilhelm
Gregor Zielinsky

The workshop will cover two important aspects of PA:

(1) Digital mixing consoles for PA and monitors.

(2) A complete soundcheck of a live rockband on stage. The visitors will experience how high-end professionals do their soundcheck, including FOH, monitors, and wireless techniques.

The special task will be to get the tricky sound of the location under control. The hall Atrium 2 is very reverberant and is not an optimized condition. This is what pros have to work with every day. The band "Rauschenberger" is a new upcoming group from Hannover around singer and leader Rauschenberger, who has a splendid and very characteristic voice. After the soundcheck, there will be a half-hour concert.

Sunday, May 10, 10:30 — 12:30

LS3 - Yamaha and d & b

Stefan Goertz
Arthur Koll


Line Source to Point Source Transformation—Technical Concept of the d&b T-Series

Increasing demands on flexibility, scalability, and efficiency in sound reinforcement applications encouraged one loudspeaker development configurable for point and line source applications by an easy mechanical
modification. Several implemented design technologies will be discussed before the listening demonstration of the performance of the system under critical acoustic conditions comparing Q-Series line arrays.


Modern IT-Compatible Audio Networks

IT-compatible audio networks and standards: Cobranet and Ethersound. Both formats will be discussed regarding their advantages and limitations. Advanced network strategies like VLAN programming offers high channel counts and a wide range of additional services via Gigabit audio networks. Now video, intercom, remote control, and DMX services may be included in a modern network infrastructure. Of course, such a network has to be as safe and stable as possible, so the redundancy concepts developed by the IT industry like link aggregation / trunking / spanning tree will be discussed.

Sunday, May 10, 13:00 — 15:00

LS4 - Sennheiser

Matthias Fehr, DKE (German Comission for Electronics and IT-Techn.)
Hubert Eckart, DTHG (German Society of Theatre, Event, etc.)
Bruno Marx, APWTP (Association of Professional Wireless Production Technologies)
Walter Möller, BLM, TKLM (Technical Conference of State Media Authority)
Florian von Hofen, VPLT (Society of Private Light and Soundtechique)

Loss of Spectrum for Wireless Production Tools

The WRC 07, World Radio Conference 2007, has identified the Spectrum 790 – 862MHz for IMT, International Mobile Telecom. In Germany more than 630,000 users operate in that spectrum: they need a new home for their activities.

The discussion will focus on the alternative spectrum that has to be opened and the transition time that can be expected.

For how long can the quality of wireless production tools be guaranteed?
Experts of the Federal Network Agency, the IRT, and the APWPT user organization and from the Manufacturers will give Spectrum users an outlook on expected changes.
