The MV-42HS is a 4-channel multi viewer that resizes and displays up to 4 inputs of HD-SDI and SD-SDI signals on a single screen. Audio level metering of SDI embedded audio signals is provided allowing audio signal presence to be monitored. The MV-42HS is most suitable for monitoring systems with mixed HD-SDI and SD-SDI input signals.
