Trasformers at truck?

ellery · 1st December 2005

I have been working up blueprints for my wiring. One thing that come to mind is. Can i mount the trasformers at the truck instead of having them at the stage?

Why do you want to do that?
What is your motivation?

I have four reasons that come to mind.

1st. I've had racks grow legs at shows before.

2nd. sometimes you are given a split from someone else's snake. Not knowing if it’s truly isolated or not.

3rd. It would make the stage boxes allot lighter. I was thinking of putting two mass connectors at the I/O panel. One that runs thru the transformers and one that bypasses the transformers. Or wire the inputs to a patch panel and have the ability to take the transformer out of line by patching around it

4th. If the transformers are installed in the truck there is a lot less chance at damaging the unit.

I see…

1: In my experience, racks may grow legs but, microphones grow fingers a lot quicker! They’re much easier to hide than racks too.

2: So, are you talking about installing 1:1 transformers or splitter transformers at the truck side? We keep our splitter transformers on stage (sometimes at FOH) and our bridging and 1:1 transformers in the patch bay (inside the truck or within the portable rigs.) We also, have plenty of extras not normally found in your average patch bays -- You wouldn’t believe the amount of transformer; pads; phase reverses; mults in our bays! It's borderline "insane."

3: A lighter stage box is cool but, do you really want to run the secondary feeds back to the stage or FOH from the truck? Isn’t that a lot more work and extra hassle or am I not understanding you? With that said, I still like your “two MASS connectors at the truck’s I/O panel a lot. One XFMR MASS, one NON-XFMR MASS. Very cool, We do something like that but it’s in the form of extra transformer isolated XLR panels.

4: I’m not sure about that… You got a better chance in having a serious accident with that truck parked (or driving) outside which could surely damage those transformers (depending on where they're installed) then someone damaging them inside onstage or at FOH…

Hey, I’m not wishing any harm to you or your property – I’m just thinking out loud about the bigger picture.

I hope this helped!

Here's a short thread from 2003 about XFMRs in the patch bay for your review...

ellery,

What did you end up doing?

ellery · 7th September 2009

Sorry for the long delay on follow up.........

Steve,

I ended up building a 24 channel 1:3 Mic Splitter using jenson transformers in a Shock mount road case, at 125+ Lbs I don't think it will grow legs in the end....

I'm in the process of building 36 channels of 1:1 Line and Mic transformers at the moment. I'm looking into the best way to buffer/isolate AES/EBU at the moment. Any idea's or advice there?

Thanks for your time Steve,

Ellery

What is the idea behind the 1:1 transformer?

Are you running all lines through transformers as they enter the truck just to be on the safe side?

Many different reasons, Level Matching and Balancing of unbalanced gear for one. My goal is to have all outside connections go thru some form of isolation.

I'm still testing a few different transformers for use. for the 24 channel I went with jenson's. I'm testing a few no names this week for use in a second splitter and for the patch bays.

As soon as the truck get here. I will start a thread for the build. It's been four years in the making, and I'm really looking forward to the build on this project.

I'm just checking on the results of the no-name testing if you did it and the build?
