The M2DIS is an optional display unit with touchscreen which can be installed internally in the front panel of the M2 Multi-Media Digital Audio Mixer. 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 M2’s DSP processor. This unit allows the user to operate the control functions of the matrix systems without any external equipment. So it is now possible to set up zone selection or input mixing without any external devices. This can be useful when the system is installed in a technical room where no external control devices are within reach.
