Liberty AV DL-AS31-2H1V
2 HDMI and 1 VGA Auto Switcher with Audio Input


The Liberty AV Solutions DL-AS31-2H1V is a multiformat auto-switcher with two HDMI inputs, one VGA with analog audio input, one HDMI output, and one balanced analog audio output. This auto-switcher supports HDMI video resolutions up to 4Kx2K at 30 Hz and multichannel audio and VGA video resolutions up to 1920x1200 at 60 Hz. In addition to passing EDID information from the display, there are multiple built-in EDID settings to simplify an installation. The DL-AS31-2H1V will de-embed the digital audio from the HDMI output signal, and output it via the balanced analog audio output port.

When in auto-switch mode, the DL-AS31-2H1V will switch to a signal input as soon as a new source is connected. When the active source is removed, the switcher will select the first source on the lowest numbered input. The DL-AS31-2H1V may also be controlled via RS232 commands or by contact closures on the rear of the switcher.
