You control it from there. The user interface of the C2N-FT-TPS4 is fully customizable for the functions you need to control (with ten programmable push buttons). The graphics engine of this device is the 16-bit Isys platform, which provides 3D graphics and animation. This device also has WAV file audio playback. With the eight connectors in the bottom plate, virtually any AV, communication, or data source may be hooked up. The C2N-FT-TPS4 differs from the higher cost QM-FTCC-TPS4 in that it lacks an RGB/component audio interface feature, a dual-channel gated mic/line preamp, the video sensing/auto-switching feature, LAN cable pass-thru, and the easy setup features. There are model variations and color options available for the Crestron C2N-FT-TPS4 media controller.
