Can TRS inputs on a powered mixer act as inserts? What I need to know is...if someone has a Yorkville M1610 powered mixer, they have mic XLR plugged into a channel, can the trs input on the same channel act as a insert and be ran back out to a board for multi-recording into a computer?

You may get a weak signal for both (incoming xlr and out bound trs line) when using the trs for a secondary signal source. If the Yorkville does have some bleedover - you may have to set the gain a little higher on both the Yorkville gain AND the aux. mixer gain when doing this.
However, if the Yorkville is supplying phantom power to the mic through the xlr (I'm not familiar with Yorkville or what type of mic you are using) you may not get any bleed over signal to the trs when using the xlr with phantom power.
It shouldn't hurt to try and see if you get a strong enough signal being sent to the (aux) recording mixer.

Sep 04, 2011 07:01 pm Well, all TRS and XLR inputs are in parallel to one another. The only difference is there are input resistors on the TRS input of the board. This helps set up the line level input to your op amp. But, both inputs are tied to the same op amp.
This means that you really can't use it as an insert. An insert breaks the chain going to the input op amp. And sends the signal out of the board. It then returns back to the board via the same input (Single point insert) Or on a separate TRS jack all together. (Discreet insert)
So, unless the board has an insert jack (or two) on the board. You can not insert. The only thing you can do, is take the signal direct into the outboard unit that you wish. Then return it to the board from the output of the outboard piece.
