OVERVIEW
The DV-HSW-21A is a 2x1 HDMI switcher supporting up to 4K x 2K @ 30Hz.
The DV-MFSW-21A is a unique switcher and a must have for installations
spanning new and legacy technology. This switcher has 1 HDMI input
supporting resolutions up to 4K x 2K @ 30Hz and 1 VGA (HD-15) input
supporting resolutions up to 1920 x 1200 @ 60Hz. The HD-15 input is paired
with a stereo audio input on a 3.5mm mini stereo connector. When selected,
the analog video is converted to HDMI and the audio is embedded greatly
simplifying connections and operations downstream. Both of the 2x1 switcher
models feature 4-way control via simple front panel push buttons, screw
terminal contact closures with LED feed-back, RS- 232 serial control, and auto
sense switching technology. In auto sense mode, the switcher will switch when
the current video source being displayed is turned off either via keyboard
function buttons or from signal loss. These options help in making these a
perfect solution for any system.
