Crestron Control and One-Touch Room Automation

EAR Professional Audio Video, in Tempe, Arizona, designs, installs and programs control systems that make complex audio, video, lighting and broadcast systems simple to run. One touch panel starts the room, recalls camera and lighting presets and keeps the meeting or broadcast on the record, so a small staff, a part-time operator or an intern can run it. EAR has delivered easy-to-use presentation and production systems since 1978.

Where control and automation help most

• Meeting rooms, hearing rooms and council chambers: one-touch control of microphones, cameras, displays, lighting and recording, so a clerk or a part-time operator can start a meeting and keep it on the record; see legislative AV
• Command and operations centers: one-touch control of every source and video wall layout; see command and control centers
• Broadcast studios and control rooms: presets for cameras, lighting and studio sources, tied into switchers, routers and LED walls; see broadcast LED video walls
• Training rooms, auditoriums and multipurpose spaces: simple touch-panel scenes for presentations, hybrid meetings and events

Control products we design with

• Crestron control processors: Crestron 4-Series processors such as the CP4N, programmed by EAR for each room or facility
• Crestron touch screens: “Intuitive touch screen control replaces wall plates, keypads, and remotes to manage AV, lighting, HVAC, and shades” (Crestron)
• Crestron DM NVX: AV-over-IP: “With video, audio, USB, and control on a single platform, you can reliably distribute anything” (Crestron); see AV-over-IP network design
• SKAARHOJ controllers and Blue Pill Server: hardware control panels for broadcast and live production; Blue Pill Server “translates between different control protocols” and can act “as a bridge between cameras, vision mixers, audio mixers, routers, etc.” (SKAARHOJ)
• ENCO vDesk: one-operator production for meetings, with integrated PTZ camera control; see meeting streaming and captioning

Control is designed with the rest of the system: Panasonic PTZ cameras and PTZ camera systems, audio and Dante processing, AV-over-IP networks and video walls.

Control and automation projects

• Arizona State Legislature and Arizona Capitol Television: audio, video, lighting, the AV network, hearing loops, Zoom hybrid hearing rooms and voting systems are controlled by Crestron automation that EAR designed, installed and manages, across more than a dozen hearing rooms and chambers. The 2016–2017 build put touch panels in every room, Crestron gallery lighting control and a Crestron interface to the voting system; EAR provides monthly engineering and Crestron programming. See the case study
• McCarthy Building Companies and Koch Industries: corporate command and control centers with large video walls and one-touch Crestron control; see command and control
• City of Phoenix council chambers: meetings are controlled from the City Channel 11 studios over city fiber, with HD video, audio and robotic cameras; see hearing rooms and council chambers

How we work

1. Free consultation: we start with how the room is used, who will run it and what has to be on the record or on the air.
2. Design: control is designed with the audio, video, lighting and network systems, not added at the end.
3. Programming: EAR’s own programmers write the control system so the touch panel shows only what the operator needs; one-button scenes cover start-up, presets and shut-down.
4. Installation and commissioning: by EAR’s broadcast installers and engineers (Arizona ROC license 276269).
5. Training and support: operator training at handoff, factory-authorized warranty support, and ongoing engineering and programming changes for clients who want it; see services and support.
