Radio Shack Digital Wireless Audio Link
CAT. NO. 15-1974
I am trying to modify this unit by taking out the wireless receiver
and replacing it with line level inputs . . .I've already done this
to the Accurian Receiver(great thread in DIY Audio).
Unfortunately, by pulling the "wireless" receiver there is not a
simple place to plug in. There is a double row socket of 32 each.
They are labeled. Some are even labeled L Audio, GND, A Mute,
etc. I will upload a picture tomorrow.
I tried connecting to the L Audio and GND connection, but no sound.
There is DC offset on both channels. . . .so the signal is just not
getting past the socket to the Amplifier.
The amplifier is a TDA7265 with the -20V on the heat sink.
There is a Mute/Standby function on the chip and I think this
is what is preventing it from working. Based on the +V supply,
the voltage needs to be -6V from that value across pin 5 to get
the amp to fire up.
Once I figure this out, I think I will be able to get the amp fired
up and running.
If anyone has had experience with the TDA7265 or this type of
modification, I would greatly appreciate it.

UPDATE.
Sounds good (not great), but better than the Accurian™ HomePlug® Digital Audio Receiver/Amplifier from another thread.
The Accurain is a multichip amp while this one is a single chip TDA7265
Played for about 5 hours yesterday at moderate volume on a full
range speaker. . .

Snagged one of these at the Goodwill today. Have been dinking with ChromeCast and inexpensive PanLong HDMI DACs. Perfect fit for this little amp.
Three wires. Might try to find a way to power the CC from the amp, but for now its provided SMPS is fine. Small hole cut in back panel for the CC to plug in, super-glued the DAC to the panel. Will add a couple screws / nuts at some point.
Streaming from Deezer via my 'droid phone. Sounds great!
