Live Sound Seminar Details
Thursday, October 20, 9:00 am — 11:00 am (Room: 1E14)
LS1 - DSP Algorithms
Chair:
Rich Frembes, Fulcrum Acoustics
Panelists:
Bradford Benn, Crown International
Klas Dalbjörn, Lab Gruppen
Dave Gunness, Fulcrum Acoustics
Langston Holland, Soundscapes
Bennett Prescott, ADRaudio
Dana Troxel, Rane Corporation
Abstract:
It's not talked about often, but almost no two brands of digital loudspeaker processors use the same filter definitions. As a result, there is no such thing as a cross-platform, DSP agnostic, optimal crossover setting. This panel looks at how to create a precise set of crossover and equalization filters for the best loudspeaker performance despite so much variability in DSP filter shapes. DSP engineers and loudspeaker experts talk filter definitions, tips on DSP settings conversion and the need for a loudspeaker filter definition standard.

Abstract:
The entertainment industry has a growing need for frequency coordination at every level of production from the Super Bowl to community theater and school events, etc. Today an ever increasing number of manufacturers are developing and marketing new license free devices that transmit audio, video, communications, and data. Desired coverage areas range from the one room community theater to the largest stadiums and arenas in the world. The panel will discuss a number of these situations and the most popular types of devices and how they work. We will include a discussion of how, in most cases, coordination and spectrum management technologies can allow almost all devices to work without interfering with each other, in the same general atmosphere. The discussions will include current and future spectrum usage. Frequency coordination protects everyone.

LS9 - Production Wireless Systems Practical Applications and Practices
Chair:
James Stoffo
Panelists:
Joe Ciaudelli, Sennheiser USA
Mark Gubser, GSC
Tim Vear, Shure, Inc.
Karl Winkler, Lectrosonics
Abstract:
From houses of worship and wedding bands to regional theaters and corporate audio , there are small to medium-sized wireless microphone systems and IEMs in use by the hundreds of thousands. Unlike the Super Bowl or the Grammys, these smaller systems often do not have dedicated technicians, sophisticated frequency coordination, or in many cases even the proper basic attention to system setup. This panel will begin with a basic discussion of the elements of properly choosing components, designing systems, and setting them up in order to minimize the potential for interference while maximizing performance. Topics covered will include antenna selection and placement, coax, spectrum scanning, frequency coordination, gain structure, system monitoring, and simple testing/troubleshooting procedures.

LS13 - Multitrack Recording for the Live Sound Engineer
Chair:
Sam Berkow, SIA Acoutics
Panelists:
Ted Leamy, ProMedia/UltraSound
Robert Scovil, Avid
Adam Shulman
Abstract:
Multitrack recording of performances is now commonplace for many artists, whether for internal reference and archiving or for potential release. This poses a new set of parameters on both the FOH and monitor mix engineers which at times are diametrically opposed. The best house sound does not not necessarily produce the best recordings and sometimes results in the FOH engineer to mix two shows simultaneously; one for live, a second for the recording. This panel will discuss the issues confronted by mix engineers and the best techniques and practices to insure both an optimal live show and recording.
