I know this may sound crazy, but why not just get an audio interface that has built in mixing? The Focusrite Liquidmix I mentioned looks very interesting and if you buy one from Sweetwater they’re including an additional DSP card for no charge.
I am looking for a decent battery powered mixer that is about the size of my hand, just to mix line level and mic levels into my laptop sound card. I have been investigating options for a day or so and have reviewed products from ART, Rolls, Nady, Eiderol, Maplin, Samson S-Mix (not battery powered, unforunately), etc.
Any experience with any of these small type mixers? I don't need EQ, just ability to mix and with clean, low noise results.
Right now, I have narrowed it down to:
Maplin 4-Channel Mono Mixer - http://www.maplin.co.uk/Module.aspx?ModuleNo=31136&&source=14&doy=26m7
Edirol M10-MX analog mixer - http://www.midi-store.com/Edirol-M10-MX-analog-mixer-p-16896.html
Any other suggestions?
