VS-700R inputs w/patch bay

This may be a dumb question, but here goes.
In planning my new VS-700 studio setup, I was wondering the following ....

Is it possible to route both channel inputs (XLR & TRS) of each channel to a patch bay,
or do they cancel each other out when a cable is plugged into both inputs of each channel?
I understand that both cannot be used for input at the same time.

I would like to have the option of using either style, without having to get behind the unit.

Also, is the Phantom power only delivered through the XLR input of each channel?

Thanks!

Gary C

    Good Question on the patch bay I would like ot see an answer to that aswel now you have mentioned it :)

    As for the Fantom I am not sure. I think you can use it for the Line in aswell

    Are you meening forinstance to use a guitar that has active picups to not need to use a battary but use the fantom power instead ? I thikn tis can be done. I could check for you tomorow if thats the case

    Its late here or I would do it now.

    Maybe some one will jump in and say

    I built a rack mountable plate for about 100 bucks, with neutrik connectors. Took about 3 hours to solder those connectors because they accept both quarter inch and XLR.  Never have to clammer behind my desk again.   









    If you're any good with a soldering iron, give it a go.  I was going to add USB, Adat, and other connectros in the bottom row, but for now its blank.

    Nice job. That was one the first things I did for the new desk - rack. Did you use Combos?

    Combos? You mean XLR/quarter inch?  Ya, Neutriks. Were the same price as the XLR, so why not.

    Still not sure if you guys have both inputs (XLR & TRS) plugged in at the same time, all the time.

    Interested to know how that works aswel if you use speakons / Neutriks for your patch bay can you inputs in each input at the back and swap from Xlr to Quarter inch on the front and the VS 700 will work that way ?

    If so am gona be geting me my soldering Iron out tomorow :)

    You can't use both the TRS and XLR inputs at the same time on the V700R. You can make or buy a patch panel with Nuetrik combos in it and use either TRS or XLR into the patch panel while running the patch panel to the XLR inputs on the V700R.
    I made one from parts for both 8 channel interfaces, running the second 8 via ADAT into the V700R for 16 channels total.

    XLR and TRS=Combos. The one to use.

    XLR to the V700R from back of the patch panel. Nuetrik combo in the panel. Jumper the XLR contacts to the TRS contacts on the back of the Combo. Run your cable from the XLR contacts. Put a XLR connector on the other end. Speakons? Different connector.

    I do understand that both inputs cannot be used at the same time,
    however, if I choose not to use a combo connector at the patch bay (since I already have 2 Nuetrik patch bays) can I run both styles (XLR & TRS) to separate patch bay locations, and use whichever, whenever (not at the same time)?

    They would however be plugged in at the same time to the 700R, although only 1 being active.

    Sorry for my insistent ignorance...

    I think that could work.  Not dure how you would split them though

    No need to be sorry. I'd have to look at the schematics for the V700R to see if there's a defeat switch on the TRS jacks which disconnects the XLR when the TRS is plugged in, I don't remember at this moment if there is. Seperate feeds to a patch panel would essentially be nothing more than an extention of the V700R jacks. I don't know why you couldn't do it that way. It might introduce some slight noise in your system. ( everything does ) At any rate, if you use combos to the XLR you can't make a mistake and double plug an input.

    Yeah you can definitely run both TRS and XLR at the same time, or TS and XLR but you WILL be altering your impedance and this is assuming you break them out to a panel like Dimaman and Craig have done. No other way really unless you use a 'Y' cable/adaptor.

    As for phantom power, it will (or should) squirt down both input options from the back of the 700R. It's important to note too that you are careful how you do your breakouts (with respect to pin to pin)  keeping in mind the importance of polarity for both phase AND phantom power.

    Cheers!
