The R2DIS is an optional display unit with touchscreen which can be installed internally in the front panel of the R2 digital audio matrix system. This unit consists of a 7” TFT display panel with a resolution of 800 x 480 px that is fitted with a resistive touch-screen panel. It is controlled by a powerful 32 bit processor which communicates directly with the R2’s DSP processor. This unit allows the user to operate the control functions of the matrix systems without any external equipment. This can be useful when the system is installed in a technical room where no external control devices are within reach.
