Hospital Case Study
Oregon Health Sciences University
Design Sound NW rejuvenates the OHSU auditorium with a new AV system based on Biamp's Audia® platform.
Design Sound NW, located in Portland, Oregon, serves the Northwest with audio, video, acoustical, testing, system design and installation, specializing in corporate AV, churches and schools.
CHALLENGE
Revamp the sound and video system in OHSU's 1930s era, 450-seat auditorium, which hosts lectures, panel discussions, concerts and community outreach events. Tangible objectives: make the system instantly user-friendly and provide clear, comprehensible sound to an audience onsite, or for remote videoconferencing, cable broadcast and satellite. Intangible goal: ensure that sound and video quality reflect the qualities of OHSU – professional, authoritative and leading edge.
Design Sound NW took into account that a constant stream of OHSU faculty and staff will be running sound and video for varied events, so flexibility and simplicity are critical. The Biamp Audia® Digital Audio Platform is just what the doctor ordered. The ease of use inherent in the Audia software allows for constant changes and refinements to the system.
The intuitive Audia software provides the ability to modify the audio to enhance the video. The system processes house audio, as well as four separate controllable feeds for TV broadcast, local recording, campus building Internet feeds and wireless for the listening-impaired. Additional low-frequency bi-amped subwoofers, dynamic processing and EQ changes in the software bussing add a sense of excitement to music.
NW Sound also redesigned the small control room into a more efficient space, with audio and video separated into distinct racks. Biamp's networked media systems significantly reduced the amount of materials and resources needed, minimizing installation time and maintenance. OHSU's fresh layout is good for the environment and more affordable, too.
“When I became aware of the Audia – both the power of the processor and the software was just amazing. The capacity of the mixing and preset recalls to different configurations is simply a matter of how much control OHSU wants to give to the end-user.”

SYSTEM SPECIFICS
System engineer/installer Craig Leppert specified two Audia DSP packages, controlled by the existing AMX Axcess touch-panel systems installed both in the control room panel and in the lectern. Linked on the internal 100 Base-T Ethernet network via CobraNet™, each Biamp Audia box is configured as a 12 x 4 digital mixer (24 x 8 total), with EQ, filters, crossover, dynamics and delays, plus other controls. As configured, the current system simulates two independent 24-channel mixers, one for house audio and one for video. The Audia DSPs also allow OHSU to process the microphone channels differently than the audio input channels from CD, tape, DVD and laptop through the matrix mixer.

CONCLUSIONS
For OHSU, the vast improvements in its auditorium deliver a stellar experience for presenters and audiences, both onsite and remote. The networked media system managed by Audia allows a greater variety of presentational modes and more flexibility in the way presenters handle the audience. And thanks to superb audio quality, the audience can be much more interactive. In a sense, the audio video system helps put a face on the institution and makes it more accessible to people. Efficient expansion options, easy upgrades and simplified support all combine to make for a healthier system – and bottom line.
“The auditorium now has greatly enhanced built-in audio capabilities that will likely grow down the line. A facility like this can grow into Audia's capabilities and do so cost-effectively, because all that is required are a few modifications to the DAP file in the software.”
