Introduction
7” Touchscreen display kit M2
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
touchscreen panel. It is controlled by a powerful 32 bit processor which communicates
directly with the DSP processor.
This unit allows the user to operate the control and configuration functions of the matrix
system without any external equipment. This can be useful for direct access, when the
system is installed in a technical room where no external control devices are within
reach or in case the system is not connected to a LAN network due to security reasons.
Touchscreen precautions
• Tap the touchscreen gently. Never use force.
• Don’t use any sharp object to tap the touchscreen. Don’t use a pen, but only
use your fingertips or stylus especially meant for use with touchscreens.
• Keep the touchscreen dry and clean. Don’t use any abrasives or cleaning
solutions to clean it. Only clean it with a soft damp cloth.
