I apologize if you've seen this message before -- my mail server's log
suggests this didn't make it to the list on the first attempt, and
since I got no responses I am trying once more. If it's just that
nobody had any advice for me, then please excuse the clutter in your
inbox.
-------------------------------------------
I'm going to use some Belden BL-1512C multi-pair snake cable (8 pairs
individually shielded) to carry a bunch of line-level audio signals
between a custom synth module I'm building and the back of the synth
cabinet. Each conductor is 24 AWG. The cable run will be about six
feet. Is this a bad idea for any reason? (I found a source selling this
cable by the foot, so I don't have to buy a thousand dollar spool.)
If it's a reasonable idea, then what kind of connector should I use
between the cable and the module's pcb? Is there a best way to assign
conductors to connector pins (e.g. alternating signals and grounds like
we do in digital ribbon cables)? What should I do with all the shields?
At the back of the cabinet will be audio jacks with a few more feet of
cable plugged into them, terminating at various ordinary audio devices.
Do I need to take any special precautions driving all this cable, or
will a simple voltage follower per signal be ok?
Thanks,
skw
