University Of Illinois At Urbana-Champaign Looks To Lectrosonics

DM Series mixer facilitates wide range of events on campus

Alice Campbell Alumni Center with the University’s Lectrosonics DM Series Digital Automatic Matrix Mixer.Urbana, IL – August 2007… With tremendous breadth and depth in its academic offerings, the University of Illinois at Urbana-Champaign has greater than 150 undergraduate and more than 100 graduate and professional programs. Encompassing a preeminent faculty that propels many academic programs to be ranked among the best in the world, the university’s emphasis on campus-wide academic excellence has built Illinois' reputation as one of the nation's premier public universities. To help facilitate the multitude of lectures, meetings, conferences, and other campus events, the University of Illinois recently opened a new alumni center, and at the heart of it resides signal routing and processing capabilities provided by Lectrosonics.

Completed in the spring of 2006, the Alice Campbell Alumni Center comprises 54,000 square feet, with a reception gallery, library, conference rooms, lounges, administrative offices, and a patio for outdoor activities. Matt Sherer, Lead Installation Technician for CITES Classroom Technologies, a group of IT, audio visual, and related specialists charged with designing, installing, and maintaining the university’s vast technology infrastructure, discussed the challenge the new complex presented.

“The main ballroom is a large multipurpose area that is used for everything from social gatherings to lectures and conferences, said Sherer. “During the design and construction of this building, it became apparent we needed the capability to route a variety of inputs to multiple destinations. Of equal importance, we wanted the ability to program several configurations so that they could be easily recalled—depending upon how the room was to be set up. To address these issues, we installed a Lectrosonics DM1612 Digital Automatic Matrix Mixer.”

“This room can be used as a single, large space or it can be divided into two smaller areas,” noted Sherer. “In addition to general sound reinforcement, we also have the mixer programmed to provide feeds to multiple press boxes as well as the Alumni Center’s lounge. The mixer can accommodate one large setup or two smaller room setups simultaneously and everything is written into system memory and is recalled via the house control system.”

The DM1612 is a powerful digital audio processing, mixing and routing system. The primary applications are sound reinforcement and conferencing in boardrooms, courtrooms, worship centers, distance learning systems, hotels and other applications with multiple microphones and loudspeakers. The basic architecture consists of 16 mic/line inputs and 12 outputs with a full DSP-based crosspoint matrix that enables every input to be routed to any or all outputs. Following the A-D conversion at each input, the signal passes through multiple DSP filters, ADFE (automatic digital feedback eliminator), a compressor and a digital delay. In the matrix, gain is adjustable from -69 to +20 dB in 1 dB steps at each crosspoint. Each of the 12 outputs provides a digital delay, multiple DSP filters, and a compressor/limiter.
