[sdiy] stereo output questions.....

[Dave Kendall]

What does the proposed stereo output connect to?

If it's a single VCA, then it'll be a mono source, and there would be 
no point running the same dual mono signal down 2 output cables, 
(whether balanced or unbalanced)
When it gets to the other end it would still be a mono signal.

If you use 2 VCAs in the output stage, one for each side of the stereo, 
then you can have a true stereo output.
(of course it depends on what's fed to those 2 VCAs, whether it be 2 
different audio sources, one to each VCA audio input, *or*, the same 
audio signal to both, but with differing CVs to each VCA (which would 
give a panned mono signal, with the pan position dependent on how 
different the CVs were)

IIRC, you're working on an ASM 2?, which has a pair of VCAs specd on 
the Elby site......

FWIW, I've always preferred 2 separate Left/right sockets for a stereo 
output, as in the studio or live, most mixer/amp/what-have-you inputs 
are set up for either a balanced or unbalanced mono signal down a 
single cable. Finding an adaptor cable ("Y" splitter)  can be a pain 
during the throes of creativity...... ;-)
Of course, if space is severely limited, then a single stereo jack can 
be a good compromise, but it does rule out the option of balanced 
outputs.

Apologies if you've already thought of this, but as it hasn't been 
mentioned so far in the thread, I thought I'd throw it in..... :-)

cheers,
Dave
