Digital Audio Extender Over Ethernet
Supports most standards to transmit one uncompressed lossless PCM audio or compressed 5.1/7.1 surround sound, such as DD Plus or DTS High Resolution Audio over one Cat5e/6 Cable SPDIF and Toslink digital audio up to 500ft via cat5e/6.
transmitted over cat5e/6, so just only need to plug in Transmitter unit to be powered.
Digital Audio Extender built in surge suppressor to protect audio equipment against damaging voltage spikes.
Supports DD 5.1, DTS, and D True HD.
