Surge protection device recommended
This product contains sensitive electrical components that may
be damaged by electrical spikes, surges, electric shock, lighting
strikes, etc. Use of surge protection systems is highly
recommended to protect and extend the life of your equipment.
Set top boxes (STB) that are connected to the outside world can
introduce surges through the system and cause components to
fail. These devices should have surge protection on all outputs
including HDMI and audio.

1. Introduction
The EXTDA is an audio extender that will transmit optical and
analog audio formats over category cable up to 100m at 192kHZ.
Distance can be extended by using lower sampling rates up to
300m. There are optical and RCA analog inputs on the
transmitter that coincide with an optical and RCA analog outputs
at the receiver. The RX has a switch to determine the audio
function. First position is RCA analog to RCA analog, the second
position is for Optical to optical, however, if the display is set to
PCM, the RCA analog outputs should output audio simultaneously
with the optical output in stereo. Power is supplied by a Micro
USB port and only one supply is needed (either end will work).

examine category cable
No Power at TX Same as above but in reverse
No Digital Audio Output is disabled at display or toslink cable
has failed. There should be light at end of the
toslink cable
