Blackmagic Design - ATEM Microphone Converter

Now it’s easy to expand the MADI input on the ATEM Television Studio switchers to add multiple microphones or external audio mixer sources. The ATEM Microphone Converter simply plugs into the ATEM Television Studio MADI port, so there's no setup required and additional units can even be daisy chained for more sources. Each converter has 4 analog inputs that are mic/line selectable and have Phantom power. The design features amazing audio quality with an extremely low noise floor, a wide dynamic range and very low distortion. The design even uses 8 separate ADC on each separate input that work together to extend dynamic range! There is also an HDMI monitoring output with scrolling audio waveforms.
