The ATI Audio MicroAmp 4MA allows up to four unbalanced audio signals to be transmitted via unshielded twisted pair (UTP) cable in a point-to-point connection. The 4-MA consists of four unbalanced audio channels which can be paired. Used in pairs, the Audio Balun eliminates up to four coaxial cables, allowing audio equipment to be connected via space-efficient and cost-effective Category 5 twisted pair cable.
