<br>
One can also think about completely deleting the Hardware audio
in- and output and doing it at the pc/soft- and hardware.<br>
For now you can do it using VAC and a sound-card.<br>
<br>
Look for example at an <a
href="http://www.esi-audio.com/products/maya44/">ESI maya44</a>,
it has symmetric in and outputs, even an microphone input with
phantom +48V,<br>
and very low latency (ASIO) and not to expensive .<br>
I have tested it on my sdr-pc and it works very good (it even
solved my audio distortions during zooming and panning the
panadaptor, h.i.)<br>
<br>
Maybe in the future, (not knowing if possible?) HP-Powersdr can
skip the need for VAC and approach the sound-card directly(?).<br>

Has there been any thought of including balanced audio input and
output on the future HPSDR boards?
<br>
<br>
One would think it would be as easy as using a different codec. A
codec that provides both single ended and balanced audio.
<br>
<br>
Having unpopulated headers on the board for the balanced audio
would be fine. I admit that there would be a minority that would
want balanced audio.
<br>
<br>
I have looked at the schematics and the PCBs for Mercury,
Pennylane, and Hermes. There is no "easy" way to add balanced
audio.
