Thanks for your help guys. I am very limited in terms of space and power sockets in my studio so I'm looking for the most compact way possible to achieve this. Ideally I'd like to have the whole set-up (lap-top, mixer/headphone amp) mounted onto my DTX rack (RS500).
Have any of you heard of Alto mixers, like this one? http://www.absolutemusic.co.uk/recor...ixer.html#info
How about that with just a headphone splitter cable?
