ST-NEDA300S Audio Extender over CAT Cable (300m)
ST-NEDA300S Audio Extender over CAT Cable (300m)
This Audio Extender can transmit digital optical and analog audio signals
concurrently up to a distance of 300m/990ft (48kHz), 150m/495ft (96kHz)
or 100m/330ft (192kHz) over a single CAT5E/6 cable. The digital optical
audio is directly passed from transmitter to receiver. The analog audio
output on receiver is selectable from the digital optical or the analog audio
signal from transmitter. The extender supports bidirectional POC function.
This is a fantastic plug and play solution for sending optical fiber and analog
audio from an HDTV back to an amplifier, AVR or multi-room audio system
which requires an analog stereo audio input signal.
