Preamps dont engage with TRS? Only with XLR?

Is this right? I have an M-audio Fast Track Ultra 8r - www.m-audio.com/products/...ackUltra8R.html

When I plug in a 1/4" the pre amps do not engage making the knobs on the front of the unit null in void. However, if I connect using an XLR - the preamps and corresponsing knobs on the front work just fine.

Is this normal? I swear I used to use TRS connections on my old mixer and it would engage the pre-amps just fine....

Any info would be greatly appreciated. Thanks.

That's how it's supposed to work. The TRS are *LINE* level inputs that should effectively bypass the entire preamp circuit.

Keeping in mind that I'm not familiar with the FTU, you might want to make sure that the XLR inputs don't have a relay (to flip them to line level) before investing in cables (or simply XLR->TRS connectors).

It might -

It might not also. But it might.

I looked for something like that - they only thing they have is in the front -

and only affects the first 2 channels since you can plug in directly to the front as well. Oh well - thanks for the info as always. I hope to have some pics of my studio up soon - I have received good advice from a lot of folks on this board (you especially) so thank you once again.
