The 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.
