The DA 12V/6V Dual EQ is compatible with NTSC, PAL, and SECAM video signals, and allows for cable runs of 600 feet (180 meters) to 1,000 feet (300 meters) or more, depending on the quality of the coax cable. When configured as a one input, 12 output DA, it also offers loop-through capabilities, which enables users to add more amplifiers and create a larger DA system or drive a local monitor.

Housed in a durable and compact half-rack metal enclosure, the DA 12V/6V Dual EQ is designed for easy integration into both new and existing A/V systems including boardrooms, training facilities, home theater, command and control center, and rental and staging environments.
