The Osprey SDAD-4 USB Powered Equalised SDI Distribution Amplifier from ViewCast is an SDI distribution amplifier which accepts any single link SDI input up to 3G and passes it directly to four outputs while preserving ancillary data and embedded audio. The amplifier has automatic cable equalisation to lessen attenuation over longer cable runs. Dip switches allow the user to select between SD and HD signals and turn off unused ports to conserve power when running from portable power sources. Powered by USB via a locking connector it can be powered by a USB charger, a PC or a portable battery pack (not included). The SDAD-4 can be used for streaming applications.
