The Mini Converter Heavy Duty - Analog to SDI from Blackmagic Design is an extremely rugged device that accepts an HD/SD component, NTSC, PAL (composite), or S-Video signal and converts it to an SDI output (a second loop-through output is also provided). You can also choose to embed SDI audio from the balanced AES/EBU or L/R analog audio inputs. Use this device to convert video from sources such as Betacam SP, VHS, set-top boxes, HDV cameras, and other similar devices. Converters in the Mini Converter Heavy Duty range are machined from a solid block of aircraft-grade aluminum and are generally designed to resist damage from rough use, whether outdoors or just in the course of live production. This super-strong Heavy Duty converter can withstand being run over by a truck and keep working. Its BNC and audio connections are protected by outcroppings of the aluminum body, unlike those on the standard Mini Converter line.
