Creating custom monitor mixes ?

To be honest, I've been getting away with the band having one mix for live recordings. I send a feed to the headphone amp and they're able to turn the overall volume up and down as they want it for each headphone. With the unit I've got, (Samsons S-Amp) there is an aux input there which I could use to send an additional signal to them from Sonars mixer (vocals, gtr, bass etc). If the mix is pretty much balanced you shouldn't have too many complaints.

I've done a band that played live and they compromised and found a mix that would suit everyone. They were happy...

I can't see why the jam hub wouldn't work, if fact that seems like an awesome idea.

Behringer are bringing out these units in the summer I think and I have to take my hat of to them, I'm quite impressed by these

Depending on if your system can handle it, you can make a send on whatever track that needs to be monitored and send it to one of the outputs of the 700r...this requires using input echo. Assign that output to a single monitor mix..Add another send to another output if someone else needs to hear the same channel.This means you will have to turn your asio audio buffer size down to more real time than performance... This will get rid of latency.. Always remember that running some effects like real space will cause latency ,so make sure to cut those off while recording.. Not all of your available reverbs do this and not all effects cause this but some do. Adjust the send to the output and run it to a headphone amp or whatever you have to split up for multiple headphones monitors. Once again if your computer can handle it you can have up to 10 headphone mixes per v700r... The only issue I have is a small amount of fan noise in this method...Its also good to listen on the headphones yourself because running input echo will automatically put what ever track you assign it to in your mains.

The system is picking up a slight high pitch squeal from somewhere. It's not in any of the recordings mind you, but its a slight distraction in the headphones using input echo...It's popular belief its the fan in the 700r itself

No... not at all ... I'm talking about using the  10 outputs via the back of the 700r...using each one for a separate headphone mix..

behringer powerplay pro-xl...(very inexpensive) its not the greatest but gets the job done...... running the individual outputs from the 700 to the front aux ins on the amp that way i can still keep my sub groups attached in the rear if needed plus you have several headphone outs per channel...oh yeah its a four channel headphone amp
