About DSH - Company History

DSH Audio Visions LLC was established in November 2009 in a spin-off network relationship with Scott R. Riedel Associates in Milwaukee, WI. President David Hosbach worked directly under Scott Riedel as Lead Audio-Video Design Consultant for several years after spending the majority of his career in audio-video system design-build contracting and on the factory level. In May of 2010 DSH-AV was incorporated as a Limited Liability Corporation in the State of Wisconsin.

DSH Audio Visions maintains memberships in the NSCA (National Systems Contractors Association) and InfoComm. Both are leading trade associations for the audio-video installation industry, providing trade shows and educational opportunities that help us stay up-to-date with products, technologies, and installation practices.

At DSH Audio Visions we have the expertise to take on many types of audio and video projects: houses of worship, school athletic facilities and auditoriums, civic performance halls, and sports and entertainment venues.

However, our core business is focused on our specialty: working in "classic" liturgical reverberant spaces of all sizes. Examples are The Cathedral of St. John the Baptist, Charleston, SC; St. Francis Xavier Cathedral, Green Bay, WI; the Chapel of the Christ, Martin Luther College, New Ulm, MN; Peace Lutheran Church, Harford, WI; Atonement Lutheran, Milwaukee, WI; St. Luke’s Lutheran, Waukesha, WI; First Presbyterian Church, Boise, ID; Christ Church Cathedral – Episcopal, Houston, TX (see our references for other examples, all of whom you are invited to contact).

DSH Audio Visions is nationally-recognized as a very-high-quality design consultation firm driven by a passion for helping the client "get it right" from concept to completion. Attention to detail with specific equipment lists and detailed conceptual drawings and bid packages, timely response to requests for information, state-of-the-art yet practical systems design, and an insistence on coming back to tune the completed audio system have become hallmarks which in many cases separate us from our competition.

Our Team

David Hosbach

President, Principal Design Consultant

David oversees all aspects of the DSH-AV operation. David is at the “point” of client relations and communications, and carries out audio and video design concepts. David also provides project oversight, will inspect installation on-site, and will perform audio system tuning.

David is a professional audio and systems industry veteran of 35 years. He graduated from Dr. Martin Luther College in New Ulm, MN in 1983 with a Bachelor of Science in Education degree, and a minor in science. He began in 1985 as an installer with a large Minneapolis-based sound contracting firm, and worked into systems design, sales and acoustic analysis.

David has spent the bulk of his career focusing on systems design, with 12 years’ experience in the audio-video design/build market and nearly ten years in the design consulting business, with a five-year stop at the factory level (Electro-Voice in Buchanan, MI from 1995-2001) working in product development, marketing and education.

David has extensive experience designing sound reinforcement systems for all types of venues: liturgical and contemporary houses of worship, school gymnasiums and auditoriums, and performance venues.
David holds certifications with Syn-Aud-Con (Synergistic Audio Concepts) as a systems designer, and with many manufacturers such as Symetrix and Renkus-Heinz for programming and setup of digital equipment. He is fluent in EASE (Electro-Acoustic Simulator for Engineers), an industry-standard computer modeling software package to aid in loudspeaker system design and performance prediction.

David is versed in AutoCAD, is trained in TEF analysis and has regularly employed this and other measurement systems such as Ivie, SMAART Live, and EASE-RA SysTune in his analysis, design and system setup work.

David has written articles for trade and end-user magazines pertaining to design philosophies in the liturgical church. He was featured in an article pertaining to sound and acoustics for traditional houses of worship in Pro Sound Canada. He has also been a major presenter at industry trade shows and end-user showcases, teaching non-product-specific concepts relative to sound and sound system design and applications. Most recently, David contributed short informative “blog” type articles to the WELS (Wisconsin Synod Lutheran)0 “Worship the Lord” publication distributed to pastors, musicians and others within WELS, and is currently preparing chapters for a booklet to be published by GIA Publications.
