Using AUX 1+2 with stereo effects Model 12

[Boboulus]

Hi,

I’m trying to use both AUX sends to get a stereo send to stereo effect pedals and then using channel 1+2 to return ththe signal. I get it to send and return the audio and I have set aux 1 to post fader. But It doesn’t sound like km getting a true stereo signal. When using the “bus” out it’s working great but not with aux so I don’t understand what could be wrong?

I have checked so levels are the same etc and can’t figure it out. Anyone try at has a clue or will this never work as I hope for and I will have to use BUS to get true stereo send and return?

Welcome to the forum. I don't have a Model 12 but the block diagram seems similar to the DP-24/32 in that the aux sends are mono signals (they are tapped off before the pan control), and on stereo tracks the aux is a mix of the left & right sides. On the DP, you can set up 2 tracks for holding left & right separately, then use send-1 for the left and send-2 for the right.

I think I might know what’s wrong. I used a stereo channel (7-8) on the Model 12 but I think I have to use two separate mono channels for this to work.

AUX busses are mono, SUB Bus is stereo. Sending a stereo channel like 7-8 or 9-10 to any AUX Send will result in a mono mix of left and right information.
Try connecting your stereo source to two mono inputs, hard pan them left-right then use AUX1 Send on the left channel and AUX2 Send on the right one (or the opposite if you like) to feed your stereo effect unit.

Thank you Max. I think I just came to that conclusion in the answer just above
