running a mult w/o imedpance matching/quality loss

im setting up a studio to track a new album and have been thinking about my setup for it. i track fully in the DAW and will be using outboard preamps for the session along with some other kinky gear.

BUT the issue of monitoring during tracking has come up and i was thinking about dragging a behringer board [flame on, i dont care] strictly for running stuff to headphone distro [furman more me system] and to run output to a webcast we are thinking about doing for the tracking session.

so i was wondering.... if i have a patchbay that the preamps are running into with them "normalled" into the ADC's... can i simply run the other side of the line in out to the boards inputs to monitor off of and create submixes on for the band without affecting the signals sent to the convertors?

Basically, yes. The high impedance of the board and converter inputs will not load the low impedance output of the pre-amp.

If you have obsolete pre-amps with transformer coupled outputs expecting to see a 600 ohm balanced load, you might see some wierdness. Adding a second high-impedance input to this won't change it, though.

so no deleterious effects in doing this? last thing i want would be to compromise what im feeding in just to monitor.

You should be able to mult one line level source to several "bridging" line inputs with no problems. I'm assuming everything involved has balanced I/O.

yes, all balanced. whew, at least one idea is going right this week for the project. now i am remembering why i dont do temporary studio setups but its still fun despite the headaches.
