  • Specifications
  • The SB-3877 is a Multi-Video switcher featuring 8 inputs and 2 outputs 
    (independent of each other) making this a true Matrix Routing Switcher. 
    The inputs are comprised of: 2x HDMI, 2x Composite Video w/Audio, 
    2x S-Video w/ A udio, 2 x Component video w/Audio and 2x VGA w/Audio. 
    The outputs are 2x HDMI w/Digital Audio, 2x VGA w/Audio. Note that you 
    can use BOTH the VGA Output and the HDMI Output simultaneously 
    giving you 2 outputs per channel for a total of 4 outputs per chassis. 
    When switching between sources, the output will fade to black then 
    fade-in to the new source you selected. Formats supported are 
    NTSC/PAL/SECAM video systems allowing you to do format conversion. 
    Supports High Definition Digital signal with data rates enabling 1080p 
    formats or if in PC resolution (1920x1200). Audio is presented on all 
    outputs regardless of selected video signal type and the volume control 
    is set for either output channel or independent of each other. It completely
    eliminates the need to constantly move around HD input and output cables. 
    Control is provided via front push buttons with LED readout or IR remote 
    controller. A RS-232 interface is provided for interfacing with third party control 
    or using the provided software. Input cable equalizer enables use of long cable 
    runs of more than 50 feet (15 meters) when using 24 AWG cable at 1080i . 
    A windows-based control software package is included to provide 
    complete control of the SB-3877 from a PC.
