I never was worth a crap at math.
For the gig in question, my intent is to tap off the main board, channel-to-channel.
At this point, that looks like 8 tracks simultaneously which is max for the 2488.
That's a little close to the edge for my tastes and so while I'm grabbing that
stuff live, I may also see how I can utilize some features of both the Peavey
PV20USB board and the 2488neo and possibly do some kind of a sub mix ??????
I'd really like to keep it as live for each vocal and instrument as possible but if
this band decides to pull any surprises on me I need to be ready for that.
Obviously, this will also depend upon the size of the hard drive in the 2488neo.
Mine is totally stock - but I have seen some posting about swapping in larger
drives which so far as I can tell may be limited to 160 GB ????? and would
obviously increase the recording time compared to a 40 or 80 GB drive.
That tapping the main board on a channel-for-channel basis appears as though
it will have to be done with the insert jacks on the PV20USB. The diagram
suggests that they are "cutting jacks" which OPEN when you plug in a 1/4" TRS
plug that needs to be wired as a SEND and RETURN plus ground. That in itself is no big deal, and sending to the 2488's inputs is no big deal. BUT, the 2488
seems to have no way to return them *individually* and that leaves me looking at
a cable that meets the TRS send/return/ground configuration for the PV20USB
BUT needs to have the send and return jumpered *inside* the jack housing so that
the signal doesn't get cut off and have nothing coming back. Then on the 2488
end, it ends up being a tip and sleeve unbalanced 1/4" plug into the 8 inputs.
It's a little bit messy but I'm not on an unlimited budget, so it's time to be
crafty with the tools I have to work with..........
