How should I hook up to a TRS pathbay

[ferndog]

Hello,

I've wired my basement with in-wall XLR and TRS connectors, as shown in the attached pic. The cables for these connectors come together in a patch panel that's 19" wide and 4" deep. My next step is to connect everyting to a TRS patchbay, but I'm not sure how to proceed. I'm concidering the following options:

1. Connect all wires to DB25 breakout panels (like this one: triple-doubleU.winfordeng.com/products/brk25.php] and then buy a patchbay that accepts DB25 connections

2. Solder wires to TRS connectores and then buy a patchbay that accepts TRS connections.

3. Buy a patchbay with solder (or punch-type) points.

4. Other option?

From what I can tell from looking around the web, option 3 seems the way to go, but these types of patchbays are kinda few and I'm not sure most will fit in my rack, which is 4 inches deep.

Any suggestions would be appreciated.

Thanks,
Fern

You aren't going to plug phantom powered microphones into those wall sockets that terminate at the TRS patch bay are you Ferndog?

Phantom Power and TT/TRS Patch Bays
If you're building a studio, this is a bad idea. Avoid it.

Use XLR connectors instead. Yes, they're not as high density as a TT bay. Don't hot patch microphones when the phantom powering is turned on. Turn the phantom power off first. Even this may not be sufficient.

The problem is that the tip of the plug can contact ground as the plug is being   With a transformerless input, this can discharge/charge the input blocking capacitors thru the microphone's output transformer. This could magnetize the core of the transformer, zap a ribbon microphone, or (remote possibility) damage a dynamic microphone.

With a transformer coupled input, you risk magnetizing the core of the console's input transformer, ruining its distortion characteristics.

If the microphone's output is transformer coupled, the microphone's output transformer could also have its core magnetized, ruining its distortion characteristics.

This is not good.

Hi Moresound,

Haven't really considered Phantom Power. I'll have to read on on this.

So, are you suggesting that I use XLR connectors to terminate the wires and then find a patchbay that accepts XLR inback on the backend? Or should I bring the wires into a DB25 breakout board and connect that to a XLR patchbay? Or should I look for XLR patch bay with solder points?

Thanks.

I'd Keep your mic cables out of the studio patch bay with other effects, aux sends and returns... Bring your studio wall plate cables back to a dedicated panel (direct through) to the same connector as the receiving one on the plate. If you want to patch any of these later you can patch from the panel to the patch bay...
