EXCELLENT LOW COST PATH TO CONNECTIVITY
Before I started using these in 2008 I had owned similar patch bays by Proco, Neutrik and some UK vendors. I've built large installations using TT-style patch bays, these took hours and hours of time to hand solder or use punch-down blocks to connect all the wires.
Finally I gave these Behringer patch bays a try and I'm glad I did. All the other 1/4" TRS patch bays I've used had a similar problem, they went intermittent after a while. Nothing is worse for creativity than to be forced to do trouble shooting while you're in the midst of a studio session. Either switches or the normalizing contacts would become oxidized and problematic in time, it always happened.
These Behringer patch bays have been fantastic, I've never received a bad unit out of the 30+ I've purchased. Currently my main mixing rig is connected to all my outboard using 10 of these and I may need to add a couple more before too long. I run everything to these patch bays so I can connect things together in the best way when it's time to mix a track.
A key to reliable function from these patch bays and the snake cables used to connect them is to support the cable so the weight of the wire is not pulling on any of the connectors, the fan end should be fluffy and loose with none of the individual wires pulled or stretched tight. If you take the time to support all your cables so the weight is off the connectors you'll have a reliable trouble-free system with these patch bays.
I love the versatility of the little 3-position switch on these patch bays, this lets you instantly reconfigure any one of the 24 signal paths without unwiring or disassembly. I leave a blank space between each patch bay so I can reach the switches if I need to reconfigure.
I bought some Proco patch bays back in the early 90's which utilized a similar scheme of a little three position switch per signal path, these cost three-times the price of the Behringer models, the Proco units developed intermittent connections that always led back to the little switches they used when I fully analyzed the failure. This kept me from considering the Behringers for a long time because I figured the little switches could never be reliable and would always be problematic on a low cost patch bay.
I was a Neutrik dealer for many years and tried some of their expensive TT-patch solutions. These are so awkward because they are really not standard connectors in pro audio, they are a throw back to the era when telephone hardware defined pro audio interconnections. Fortunately I had an opportunity to sell off my $2000 of TT-patch bays (for a small profit even) and then I switched to these TRS models by Behringer.
When you think about it a TRS patch bay really makes a lot of sense for a modern audio system. It's easy to connect and in my experience can be very reliable, easily as reliable as any TRS connection to any piece of electronic equipment.
My current studio system has over 2000 audio connections made up using TRS plugs. Mostly I make my own cables and I do all my own wiring in the studio. I never have any problems with connections going bad.
One last tip, I use Cramolin R5 Deoxit on the plugs before I insert them into these Behringer patch bays. Clean plugs are cheap insurance for reliable connections.
Good luck and good music to all!
