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).

Optical
Set the audio output to PCM
in the menu of the display
and the RCA connection will
output stereo
To audio system
NOTE: Switch is set to TV/
Optical so that the RCA audio
selection will get PCM audio
from optical out of display

NOTE: Switch is set to TV L/R
In this case the RCA audo
comes from the RCA input.
The optical will now pass
multichannel audio from

Optical supports
multichannel audio. RCA
audio comes from RCA audio

7.Trouble Shooting
Symptom Possible Cause(s)/Check
No Power at RX
If Micro USB is plugged in to RX, check power
supply and/or USB cable. If powered at TX,
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
No Analog Audio Make sure there is RCA output going into the
RCA connection at the TX. If using toslink
make sure switch is set to “TV Optical” and
that the display is set to PCM audio in the
display’s set up menu
