Use the front-panel buttons, supplied remote control or RS232 interface to select the input source, choose one of the eight display formations and set the output resolution. If required, enable the audio extractor and connect external speakers via the 3.5 mm stereo jack or S/PDIF output. For ceiling installations, use the 180° rotation function via remote control.

Recommendations

For stable operation, use high-quality HDMI cables within the recommended length limits and ensure the source device can output the required 4K/60Hz signal. When installing in public or ceiling-mounted locations, verify IR receiver accessibility or use the IR extension. Mount the controller on a stable surface or wall and allow adequate ventilation around the metal housing.
