Blackmagic Design ATEM Studio Converter 2 SWRCONVRCK2 is perfect for live production because it includes 4 optical fiber converters in a one rack unit size chassis, combined with built in talkback features. ATEM Studio Converter is designed to operate with ATEM Camera Converters and allows the use of low cost optical fiber to connect cameras long distances away from the live production switcher. ATEM Studio Converter supports both embedded SDI tally and also includes talkback features using the spare channels 15 and 16 in the SDI connections to the camera.
