A Houses of Worship Case Study: Soul City



Laz Rios, Soul City Tech Director and
Ron Cook, Chicagoland Worship Audio Engineers 


A Houses of Worship Case Study: Soul City 

Soul City, in the West Loop, is a fine example of well applied tech. They have all the pieces.... Live cameras with IMAG and live stream, wireless ears and mics, well installed line arrays that actually sound good. Virtual Soundcheck. Just enough lighting to be cool. A backstage tech crew with clever ways of communicating. Lots to talk about, all of it a notch above entry level, but implemented so well you might mistake them for having an unlimited budget. 

Laz and his team will give us a tour of their facilities and demonstrate their Virtual SoundChecks. Ron is ideally placed to give those of us new to Worship Audio a sense of how Soul City fits in the larger context. 


Laz Rios, Soul City Tech Director

Lazarus Rios is the Technical Director for Soul City Church. Laz spent many years on the road touring as a front man for a metal band, where he gained a love for music, and production. After touring he transitioned into special event management where he spent 5 years building and managing teams. It was in that season that he felt a call into full time technical ministry. Laz joined the Soul City Church Creative Team in March of 2018. He now recruits and trains all production volunteer teams and oversees AVL for weekend gatherings and throughout the building.

Ron Cook, Chicagoland Worship Audio Engineers

Ron Cook is a Front of House, Monitor, and Mix Engineer. For 15 years Ron was a staff audio engineer at Willow Creek Community Church in the Chicago Suburbs. In late 2015 Ron left Willow Creek to form Split The Difference Audio, LLC working with production companies and churches locally in the Chicago area and across the Country as well. In addition, Ron provides studio and live webstream mixing services. Ron is a DPA Microphones Master Club Member and was the 2018 Vice President of the Chicagoland Chapter of the Engineering And Recording Society (EARS)

Renowned audio engineer Robert Schulein, beloved son of the late Arthur and Jeanette Schulein, peacefully died in his home on New Years’ Day 2019 after a valiant, seven-year battle with cancer. The Fellow and Past-President of the International Audio Engineering Society and prolific inventor, with a wealth of patents to his credit in the fields of acoustics and electroacoustics, is survived by his wife, Joyce, and two daughters, Heather Davis (Rick) and Jennifer Yoder (Mark) and their son, Max Yoder, brother Thomas Schulein (Vivian), nephews Michael and Robert (Kate) and their daughters Harriett and Eloise. He was 76.

Born in 1942, Schulein was raised in Rockford, Illinois and showed early on a knack for technical tinkering. He went on to receive BSEE and MSEE degrees from the University of Wisconsin, Madison, where he did research on piezoresistive semiconductor transducers. It was right out of college in 1966 when Schulein landed what would become a thirty-year career at Shure Brothers Inc. in Evanston, Illinois. Achieving the title Staff VP & Director of Business Communications & Industrial Products, his responsibilities included research & development of microphones for automotive cellular telephone systems, R&D of microphones for land, mobile and related communication systems, as well as R&D of microphone systems for speech recognition applications. In 1977 he was elected to Fellowship in the Audio Engineering Society and that same year also won the Audio Engineering Society Publications Award. In 1990 Schulein was awarded the Audio Engineering Society Board of Governors Award.

His earlier work at Shure was in the area of condenser-microphone research, development and design. He led the group effort to introduce Shure's first professional condenser microphone, the SM-81. While at Shure, Schulein managed the Home Theater Sound (HTS) division, which pioneered the development of the first enhanced matrix decoders emulating the professional Dolby products in theaters. This work led to the development of a complete line of processors, power amplifiers, and loudspeakers for high-end home theater systems, predating the introduction of THX performance concepts. The HTS division also developed and pioneered the use of enhanced matrix encoders and decoders for professional applications. He also introduced matrix surround-sound encoding to baseball television broadcasting, episodic television, Saturday Night Live, The Grammy Awards, and Super Bowl XXIV in 1990.

After his time at Shure, Schulein held positions at Etymotic Research, Inc. (now Lucid Audio), in design, research and development. During this period, his focus was in areas of consumer electronics, professional audio, telecommunications systems, audiology, and hearing-aid component development.

At the time of his death he was owner of RBS Consultants, an international consulting firm, which provided consulting services in areas of acoustics, product research, product design and development, project management, and audio/video recording engineering and production. His areas of specialization included professional and consumer audio products and applications, telecommunications and the hearing-health industry.

Schulein took great pride in staying active in a number of professional organizations within the audio and hearing industries. He was a Fellow and Past President of the International Audio Engineering Society, where he received the Publications Award in 1977, the Board of Governors Award in 1990 and the Bronze Medal in 2013.

At the time of his death he was serving as a Vice-Chair of the AES Technical Council, and as Chair of the AES Technical Committee on Hearing and Hearing Loss Prevention. He was proud of his implementation of the Richard C. Heyser Memorial Lecture series, which was established in 1999 and remains active to this day. He was a member the American Auditory Society, as well as the American National Standards Institute working group on hearing-aid measurements.

Schulein's lifelong interest and successful track record solving difficult engineering problems led to his personal and professional development of, among other inventions, miniature directional microphones for hearing aids, acoustically transparent non-porous wax barrier for the hearing aid industry, plus an advanced professional in-ear monitoring system used by a list of today’s top performers.

Many may also have been aware of his passion project, ImmersAV Technology – a patent pending audio technology and high-definition video process to create “you-are-there” musical experiences. He finally was able to achieve his dream of becoming a music producer, having the opportunity to work on recording projects with many talented musicians of Chicago.

Robert was a loving son, husband, father, brother, uncle and grandfather. He was very proud of his girl’s accomplishments and he enjoyed being a mentor and teacher to his grandson, Max, to his two nephews, Robert and Michael, and to many others. 

Never taking a day off from his engineering efforts, Schulein worked up until his decision to enter hospice care at his home. He passed away peacefully on New Year’s Day.

There will be no formal service at this time, but a celebration of his life will be held for him at a later date.

Donations in his name may be sent to the North Shore Foundation Kellogg Cancer Center
