Attention:
The audio fiber extender signal can be outputted to the power amplifier, but the power amplifier audio source can not output the audio source signal to the fiber extender, otherwise the fiber extender will be burned.
We suggest that user use the short optical fiber cable to do first time test to ensure that all the functions of the equipment are normal, and then do long-distance transmission.
