I have the Yamaha MG10XU.
It is a Mixer with real good sound and 192khz audio inteface.
For me enough inputs (4 Mono and 3 Stereo Ins) and a real nice FX-Unit as well included.
I have connected:
A4
TR8
Volca Bass
iPad

For your needs a Yamaha MG12XU would be more useful. It has one more Stereo In.
The sound to my MacBook in Logic is really good.

With such a Unit you can connect to PA, your PC/Mac, your monitors and have a nice effects unit as well.
