why not use your V3? If your line signal is hot you can enagage the internal -15db pads.
I haven't run my V3 that way yet but I certainly could. That is what I would use for taping a show from a sbd feed.
What I am looking for would mostly be used in the equipment rack I am putting together for when I am paid to do live sound and recording. I was originally thinking of something battery powered in the event I wanted to use it for taping off the board while also running my mics.
Good to hear that people have successfully used the v3 for patchin out of a sound board. Have you guys needed to use any attenuation other than the V3s build in pads?
