Symetrix At The Hub Of System Supporting Hybrid Classroom

Sacramento Productions Services employs Prism 12x12, Composer and more in meeting the needs of in-person and Zoom classes at River City Christian Church in California.

Sacramento Production Services recently partnered with Symetrix and Quinn Klarer, the company’s field applications engineer, to create a hybrid classroom to enable students to interact both in-person and via Zoom at River City Christian Church in Rancho Cordova, CA.

“He (Klarer) came in and really helped us with his expertise. This involved adding a Shure MXA910, a Data-Video PTZ Camera, and a capture card to the existing computer system,” says Brian Webber, install tech and programmer with Sacramento Production Services. “I needed a way for the control of all systems to be easy for the end user and this required a lot of programming. I also purchased a 12-inch touchscreen for control. I wanted the ability to integrate the Data-Video PTZ camera into the system and connected it to the Symetrix Prism 12×12 that sent control data over the network. I was having trouble getting this working on the Windows computer with just straight IP commands and Quinn suggested I try the Bolen PTZ Intelligent Module that he had created.

“This module was perfect for my needs,” he continues. “Even though it was written for a different brand of camera, we were able to adapt it and make it work. This Intelligent Module includes pan/tilt control as well as preset recall which I copied all those buttons to the Symetrix SymVue touchscreen. I was able to integrate it with the Shure MXA910 microphone and have the camera recall the preset based on where the person was standing in the room talking. I routed all the individual Dante channels into the Composer file and had each one route through an audio level detector and connected that to a remote-control number module. This then triggered the corresponding camera preset. It took some tweaking, but it works fantastic.”

The system also employs five Visionary Solution encoders and two decoders. “With these, I’m able to create a preview of both input and output on the touchscreen as well as have that preview be a button,” Webber explains. “I’ve got it set up so the end user can touch the source they want, then touch the destination they want. I find this so much easier to use and explain than a standard classroom switcher. The ability to have the picture/preview is so helpful. I’m able to send all these commands to the encoders/decoders with intelligent modules including the source select, HDMI CEC commands (on/off), and Bluetooth pairing.

“I find Symetrix products easy to use, yet have the complexity to address all the needs at the same time. I absolutely love the ability to control every piece of gear on the network through the system; this was really important to me,” he concludes. “We recently started integrating Visionary Solutions products into our installations, and the number of things you can do integrating these two products together is staggering. Also, the 64 channels of Dante are wonderful. For me, I find the analog I/O to just be bonus for me as I’m trying to use Dante as much as possible. The ability to patch everything in the Composer file is great.”
