Hi there, I apologize in advance for my ignorance and silly questions.. I’m very much new at this haha. But I’m attempting to add direct outs on my Yamaha m1516 and had some questions for anyone willing to help.
I was planning on wiring in a CA2623 transformer right off of the echo pre/post switch. Many questions
1. Is this the right transformer to use? The spec sheet says 75ohm primary. Seems low compared to the 600:600 I’m used to seeing but I’m trying to wrap my head around transformers not having inherent impedance rather they reflect impedance.
2. Will having the transformer on the channels output opamp at all times negatively affect the signal down other paths? For instance if I try to rout to another bus simultaneously. Or come mixdown time when I will only be using stereo bus outs.
3. It was recommended to me to use a dc blocking output cap. Necessary?
What size would be recommended? 470uf? What voltage rating?
4. Would it be best to wire the xfrmr 1:1 or 1:2? Maybe it’s subjective but I didn’t know if this would affect opamp loading.
Sorry for the barrage of questions, I’m just trying to get this thing done and quickly realized I was a little over my head haha. Can’t thank you all enough!
