| This is the 2nd time I read this, and I'm a bit unclear what you want.
My shot :

This would require some sort of 8x16 switching matrix, IF you require
the ability to send any of the 8 outputs to any of the 8 inputs. ouch.

Sounds like a bar switch. A bit simpler, but overkill.

Call me naive, but consider this : an audio patchbay, with the
recorder outputs each normalled to their own mixer input. That is,
the signal 'normally' flows in from the tape deck and out to its mixer
channel. You can interrupt the normal flow by utilizing the front
panel insert points and patch cords. Forgive me for belaboring this,
but a surprising number of people aren't patchbay literate. If you need
to redirect or use outboard (non-mixer-loop) effects on a track, use
1/4" patch cords on the patchbay. That's what I do, and have lots of
flexibility.

| A suitably wired set of 16 9-position rotary switches should suffice.
This is cheap if inelegant, but it solves the problem in full
generality. Basically, each of the 16 inputs has a rotary switch.
One of the switch positions is wired to the "normal" input for that
channel, and the other 8 are wired to the 8 outputs from the reel to
reel. The switch wiper/common goes to the mixer channel input.
This approach assumes that at any given time, you only want *1* input
connected to each mixer channel. I think that's a reasonable
assumption/limitation. Note that you can, with this setup,
send the same input to multiple mixer channels, which may not be of
much use. Also, you must observe suitable shielding and grounding
practices to avoid the introduction of noise.
BTW, I'm not sure how your goal and strategy relate to one another.

You know I never gave the patchbay route a thought. I did come up
with the rotary switch idea but wondered how much noise would be
introduced. I think the use of the patchbay will be the safe and
if not least expensive, less of a hassle way to go.
Few! I was preparing to breakdown and buy a real dedicated mixer
but this patchbay idea is going to save alot of money. I've just
started to normalize my current half-normal patchbay so I'll go
home today and cut somemore wires.
Thanks for the lighting over this marblehead.

| 2614.4 | Enliterate me about patchbays | DREGS::BLICKSTEIN | I'll have 2 all-u-can-eat platters | Tue Apr 23 1991 12:13 | 9 |
| I confess to being a patchbay illiterate.
One question I have is that I often see patchbays that are 2xN.
Are there patch bays that have "default routings" such that if
nothing is plugged into to (say) the top left-most plug the signal
is routined by "default" to the bottom left plug?
Basically the question is, do I need a patch cord to make ALL
connections, or only to deviate from the "default" connection?

What you've described is commonly called a "normalled" patch bay. This
is the way to go, unless you like that "early Moog" look.
|
| 2614.6 | Or is it a Half-normalled Patchbay | MPGS::HASTINGS | | Tue Apr 23 1991 13:04 | 11 |
|
Isn't a normalled patch bay one that doesn't have above mentioned
connections. I ask this because I own a Furmman patch bay that they
call half normalled. There's this little switch that when a plug is
inserted into the top and bottom plug a connection is made between the
two. With this I am able to chain my compressors, Eq and Hush together
without jumpers and still use each unit seperatly.
Just to add more confusion.

| Seems this has been discussed in here recently, but of COURSE it was
buried inside another topic.. I have a Furman 2x20, 1/4" front, RCA
rear bay, 1 rackspace high.

| 2614.8 | there's more.. | SALSA::MOELLER | I played TETRIS with ELVIS | Tue Apr 23 1991 17:26 | 16 |
| Using the front top out only duplicates the signal, normal signal path
is still in use:
+---------------+
<to anywhere<-------+------<from tape track 1
| | |
> +------>to mixer channel 1
+---------------+
..But using the bottom front input DOES interrupt the normal signal
path..

| 2614.9 | I liked the idea but. | MPGS::HASTINGS | | Wed Apr 24 1991 08:59 | 12 |

I liked your idea and tried it yesterday. Well I found it best to
snip the jumper and break that normalled signal path. Otherwise not
only would I have to insert a dummy plug into the bottom front I still
had insert a jumper to the new channel, thats two steps instead of one.
So now I have all my tape decks Inputs and Outputs plus the mixing
console channels on one patch bay. It might seem messy at first but
I've looked at my other possiblities and this seems the least. And I
still have 4 unmodified channels on the patch bay.
