DL-AS21C Summary

The DigitaLinx DL-AS21C is a compact multi-format switcher with support for video resolutions up to UHD (4096x2160). Featuring one HDMI input and one VGA input with stereo audio, the DL-AS21C automatically or manually switches either input to a single HDMI output.

The DL-AS21C features multiple methods of control. When set to Auto, the switcher will automatically switch to the newest source device added to the DL-AS21C with VGA taking precedence should multiple sources be live simultaneously. The DL-AS21C may be manually controlled by switching via the front panel, RS232, or contact closure.

As an added benefit, the DL-AS21C features a built-in CEC controller to power on/off the connected display by auto-selecting the source device’s status.
