However, how often would you need to change the normalling? You'd only need to do that if you completely changed what you have plugged in the back, which only happens with a major reorganisation with replaced, added or removed equipment. How often do you expect to do that?

Good point, I'd probably use it in normal mode most of the time

I am considering a patchbay for my modest cassette dubbing setup but I would lake to buy one that uses solder connections. This is not shown in any photos I have so far seen.
I wish to avoid a row of redundant plugs in the rear.

The only one I know of for A-type sockets is the Signex CPJ48T which has direct solder terminations on the rear. And I think I've seen another Signex CPJ48 model with multiple D-subs at the back but I can't see a model number for it!

Almost all the other A-type patchbays have A-type sockets at the rear simply because that's most convenient for the majority of the market.

Typically, you'd have some sockets normalled -- eg, inputs to sound desk channels, and sends/returns to effects processors -- and some straight for general pluggable access to standalone devices... but once allocated the normalling doesn't need to change.

Yeah, I am an awkward bugger! Looks like I shall have to pay more for less, like those 'slimmed down' sports cars!

.

This one has D-subs, and I do have the option of buying one of these half-price with the Audient) What do you reckon?!

Yes... but it's TT/bantam, and probably a lot more holes than Dave would want! :lol:

Elf...do you have a labels supplier?!
I have an Excel spreadsheet, some clear tape and a few bits of blu-tack!

Allow me to also add that I had a *lot* more trouble with the reliability of my previous Signex bays than I've ever had with the Samsons! In fact I had a Behringer bay that was also much more reliable than my Signex bays!

Which Signex? The low cost Q-patch (with reversible cards), the original (1980s) Isopatch, or the more recently introduced and more expensive Isopatch with sealed sockets that we've been discussing here?

I'm curious too, I have a couple of virtually unused Neutrik patch bays, a Signex Q-Patch and a Signex Isopatch (the latter two bought used many years ago). I only need a single patchbay now so am thinking the old Isopatch might be the one to go for? I can't see any significant differences in quality between them but is the old Isopatch likely to be any more reliable than the newer Neutriks?

Dave, if a Neutrik or the Q-Patch is any use to you you can have one for the cost pf postage?

There's a picture of it at

http://www.signex.com/cpj_image.html

It is listed as the CPJ48D25 and appears to be available from

https://studiocare.com/products/signex- ... r-contacts

and

https://sxpro.co.uk/signex-isopatch-trs-db25

amongst others.

Good to know I hadn't gone mad! :D Thanks James.

...and it's a British manufacturer too. Another good reason... :lol:

I don't know what version mine were. They were labelled CP48, IIRC and had solder tag 'targets' for normalising (a hassle to do - and a bigger hassle to change). If I wanted to change just one normalisation option the whole bay had to be de-cabled and pulled out to get to the soldering - never again!

I was constantly having to reseat cables and clean them to get them working. I've had no such trouble with any other bays.

I'm surprised no one has mentioned Neutrik patchbays. I have a couple of Neutrik NYS-SPP-L 48-point TRS patchbays that have worked flawlessly for 10 years. I like the way you can just flip the PCB modules to configure each in/out pair for half-normalled, split, or isolated. Reasonably priced. And no soldering (unless you want to save money by making your own interconnect cables). I make label strips in Excel and print them on ledger-sized paper, and glue them on with rubber cement.

Indeed Hugh. AND a lot more money! I would also have to buy a rake of bantam* jack patch leads'

*Very OT! Used to have a bantam cock at home when I was a kid. Pugnacious bugger and would attack anyone who went in the garden where it had free reign. Trouble was we had an outside lavvy then and I used to have to guide visitors down the path with a broom to fend off the creature!
