Control Server is a flexible and extensible approach to the control of Symetrix Composer-enabled DSPs and select third-party AV components. The centralized server-based technology enables comprehensive design, deployment, and maintenance of large and sophisticated systems employing numerous control endpoints supporting multiple simultaneous users. Control Server’s wired Gigabit Ethernet port enables control via dedicated AV or general purpose facility networks, as well as direct communication with networked DSP hardware. Operating in wireless mode, Control Server functions as an access point providing mobile device connectivity – in essence providing a secure “AV control island”. Control Server is designed into a system using Composer – Symetrix’ award winning open-architecture application. Composer is used to locate and program Control Server and other Symetrix DSPs and accessories. Control Server’s browser-based administration is then used to manage app licenses, users, and user access. Mixer supports up to 32 virtual channel strips, each with an assignable fader and a mute button, and dynamic screen-sizing and orientation. Mixer can be used on virtually any mobile device. Users can group and hide channels, assign custom labels and colors, and adjust fader resolution and travel. Multi-touch functionality makes possible simultaneous adjustment of multiple faders, just like a physical mixer. A Mixer instance can be saved to a smart device’s home page for instant access, appearing as a native app. Multiple users can operate the same instance, and user access control can be provided via username and password security for each user.
