Blackmagic ATEM Microphone Converter
The ATEM Microphone Converter expands the audio input capacity of an ATEM Television Studio switcher by converting four analog XLR inputs to MADI. It plugs into the switcher's MADI port, so instead of the switcher's built in mic inputs you get four professional combo XLR and 1/4 inch jack inputs, each switchable between mic and line level with selectable +48V phantom power for condenser microphones.
Under the hood each input uses 32-bit float digital preamps feeding high dynamic range converters for clip-free 24-bit, 48 kHz capture with 131 dBA of dynamic range per channel. A MADI output carries the converted audio, and a MADI input lets you daisy chain multiple converters so more than four channels can ride a single MADI connection. A 12V DC power input plus USB and Ethernet handle setup and firmware updates. Blackmagic part number BMD-SWATEMTVSTDMC.
