The Extron DVI DA2 and DVI DA4 are DVI distribution amplifiers with two or four outputs. Both models accept a single link DVI signal and distribute identical signals to attached devices. They also provide DDC - Display Data Channel routing to the local output, allowing EDID - Extended Display Identification Data handshaking, which ensures proper video output and reliable display of material. These DVI distribution amplifiers are ideal for any application where high resolution video signals need to be routed to multiple destinations, and a fully-digital signal path from source to destination is preferred.

The DVI DA products also feature automatic input cable equalization, which restores and reshapes incoming DVI signals, minimizing jitter effects that can be a common problem where multiple active devices are in the signal path.

Both models are housed in rack-mountable 1U, half rack width metal enclosures. An external, universal power supply is included for worldwide power compatibility.
