Legislative AV & Hybrid Meetings

EAR Professional Audio Video, in Tempe, Arizona, designs, installs and supports broadcast and hybrid meeting AV for legislatures, city councils, commissions and boards. At the Arizona capitol complex, all audio, video, lighting, AV high-speed network, hearing loop, Zoom hybrid hearing rooms and voting systems are controlled by Crestron automation, designed, installed and managed by EAR Professional Audio Video, across more than a dozen hearing rooms and chambers that broadcast hundreds of hours a month while in session.

Properly designed, a single operator can remotely manage multiple HD cameras, microphones, presentations and remote video conferencing. We integrate broadcast operations into simple central control with “one button” automation of complex room setups, so part-time or intern staff can run a meeting without missing a minute of broadcast or recorded content. Read the case study: hybrid meeting AV for the Arizona State Legislature, City of Phoenix and City of Glendale.

Frequently asked questions

Who installs hybrid meeting AV for city councils in Arizona?

EAR Professional Audio Video, in Tempe, Arizona, designs, installs and supports broadcast and hybrid meeting AV for city councils, legislatures, commissions and boards. Its Arizona government work includes the Arizona State Legislature hearing rooms and chambers run by Arizona Capitol Television, the Arizona Corporation Commission, council chamber broadcast systems for the City of Phoenix and the City of Glendale, and broadcast cameras and routing for the City of Surprise.

Can one operator run a council meeting broadcast?

Yes, when the room is designed for it. Remote-controlled PTZ cameras with presets, a production switcher or automated production system, and Crestron touch-panel control let one operator manage multiple HD cameras, microphones, presentations and remote video conferencing. At the Arizona capitol complex, rooms are run from a central broadcast center.

Can cities buy on the Arizona state contract or 1GPA?

Yes. Arizona state agencies and State Purchasing Cooperative members, including many cities, towns and counties, can buy equipment, installation and support from EAR Professional Audio Video through Arizona state contract CTR075309. Eligible public agencies in Arizona and other states can also use national cooperative contract 1GPA 22-02PV, as the City of Glendale did for its 2026 council chamber rebuild. Contract pricing is available on request.

How do remote participants join a hybrid hearing without disrupting the broadcast?

The video-conference platform, such as Zoom, is integrated into the room audio, displays and broadcast. Room microphones are mixed with the remote audio, remote members appear on room displays, and a Crestron control can mute the Zoom feed without affecting the broadcast.

What assistive listening does a public meeting room need?

Under the Americans with Disabilities Act, government meeting rooms need an effective assistive listening system. A hearing loop sends the room audio directly to telecoil-equipped hearing aids and cochlear implants without background noise. EAR Professional Audio Video installs Listen Technologies hearing loops in legislative hearing rooms and chambers.

How are public meetings captioned, streamed and archived?

Program video is encoded and sent to a streaming and archive platform that adds live and on-demand closed captions and keeps an archive of past meetings. For Arizona Capitol Television, EAR Professional Audio Video integrated the Invintus streaming and archive platform, including captioning for more than 10,000 hours of archived meetings.
