Meeting Room Case Study

Integrated Audio, Video & Control: Chicago Teacher's Union


The Chicago Teacher's Union (CTU) recently consolidated its Union and Foundation activities to one 111,000 sq. ft. site prompting a significant technical upgrade. CTU was in need of a solution that was flexible enough to easily move audio, video & control around a large facility with 24 meeting rooms. 

  1. Third-Party Integration: The system needed to perform processing and control tasks for individual rooms and easily control a number of third-party equipment such as video streamers, PTZ cameras, IR controller, table mics and more. 
  2. Easy-to-Use: With hundreds of employees and volunteers using the space each week, the solution needed to be intuitive and self-explanatory. 
  3. Time and Cost Sensitive: Traditional hardware-based control solutions potentially pushed the project over budget. CTU needed a solution that would bring down hardware and programming costs, while allowing them to meet a compressed time frame. 
  4. Enterprise-Wide Support: With several different types of meeting rooms throughout the site, they needed a single, unified platform to would make integration easy. 
  5. Scalability: CTU needed a profoundly scalable solution that could accommodate future growth, and a way to move control capabilities around the facility without locking into dedicated control hardware.

“We originally had a competitive solution, but we quickly realized we could save significantly by relying on Q-SYS to manage control.”

Integrated Control:

A traditional hardware control scenario requires a programmer to connect up to 50 to 80 individual integration parameters for one, small meeting room. This arduous task is effectively eliminated with the
Q-SYS Platform because all audio, video and control elements are contained in a single platform that speaks natively to each other through an integrated processor. 

Simplified Control:

When creating user control interfaces (UCIs) within Q-SYS Designer Software they simply dragged native control elements from the UCI editor onto a Q-SYS touch screen controller. For more complex third-party device integration, project integrators used the built-in scripting engine within Q-SYS which uses Lua, a lightweight, open source modern programming language. 

Scalable Control:

Q-SYS is a full-feature control platform. If CTU were to undergo another major expansion, integrators won’t be faced with a “rip-and-replace” scenario for the control or audio programming. They would simply add network I/Os to additional rooms and push the new design to the upgraded Cores without having to reprogram. All Q-SYS Core processors are completely backwards compatible.


System Components:

Q-SYS Processors

1 – Q-SYS Core 500i integrated processor
2 – Q-SYS Core 110f unified processor 

Q-SYS Touch Screens

14 – TSC-3
9 – TSC-7w
3 – TSC-7t 

QSC Loudspeakers

50 – AD-C6T
7 – AD-P6T
32 – AD-S4T 

QSC Amplifiers

11 – SPA4-60


Software-Based Control = Money Saved

The use of Q-SYS to manage all control requirements has yielded an approximate 10% saving on overall system costs. “We originally had a competitive solution, but we quickly realized we could save significantly by relying on Q-SYS to manage control,” says Mercer Aplin, Thershold Acoustics Consultant 

Remote Support and Flexibility

With two expansions already done and more planned, Q-SYS offered the flexibly to grow and scale as required, which can be done with a simple firmware update to the Q-SYS Cores, which takes only minutes.
