This VigilLink VLEX-ACT300-TR Audio over CAT 5e/6 Extender can transmit digital optical and coaxial signals concurrently up to a distance of 300m (48kHz), 150m (96kHz), or 100m (192kHZ). The receiver's built-in DAC converts either of the digital (coax/toslink optical) signals to a 2CH analog stereo audio output. Support one-way POC function (the receiver will power the transmitter over the CAT cable).
This is a fantastic plug-and-play solution for sending optical audio from an HDTV back to an amplifier, AVR, or multi-room audio system which requires an analog stereo audio input signal.
