I am trying to use my external rack effects with the send/return outputs on the back of me 2488neo. I am running cables to two separate units by sending two lines from effects send 1 and 2 out of the back of the neo and have the two returns going back into the F and G inputs respectively for each effect. I am getting plenty of signal to the outboard effects(their LEDs' are confirming that) but I can't get those signals back in to any of the channel/tracks I'm trying to record. I have adjusted the effect send levels of both of the effects 1 & 2 and I still can't get the effects into the channel. I have also raised the input level of both of the returns on inputs F & G. Any body else out there using outboard effects on the neo that could help me with this - it would be greatly appreciated. The manual is extremely vague with this. Peace - Gman
