I am sending a mic & guitar into my Tascam 12. I need to duplicate those signals for a harmonizer. I assume (maybe I'm wrong) that I should go into the T12 first and then pull them out using the insert jack. I'm not actually running an insert, as I do not plan to return the effect to the same channels. Instead, I want to use the inserts (or a bus) as a duplicate output, and I'm going to return on separate "wet" channels. OPTION ONE: INSERT JACK. TS OR TRS? I know this can be done for channel #1 and 2 by plugging in halfway, but I've never tried it before and don't know what to use. My effects box requires XLR on its end. What do I use on the Tascam side to make this work: TS or TRS? And of course this can't be balanced--there aren't enough clicks--so how's the fidelity? OPTION TWO: BUS? CONTROL ROOM? Is it better to use a bus (I don't 100% understand the signal flow here) or an insert? I know that I can easily run those two channels to SUB--I don't really have much else on SUB at this point. But as far as I can see, I'd be sending post-EQ and post-compressor, which I don't want. I think the "send point" control only affects SD card recording and there is no option to (for example) send to SUB or AUX1 without going through EQ and comp. Am I wrong? OPTION THREE: IS THERE SOMETHING ELSE ENTIRELY? If one of you lifetime-recording-studio types is thinking "Every studio has this issue; why isn't he just using a cheap feeblejarber box like everyone else?" the answer is simple: I don't know what the so-to-speak feeblejarber box is, or that it exists, and so I don't own one. Feel free to enlighten me!
