I used this item busking on a 1 channel amp, a guitar and backing track, taking 2 channels. Then at a party an acoustic guitar, bass guitar, and an SM58 into one channel of the PA. I used the small mixer to control sound levels, adjacent to me for local control. The sound is clear, with no artifacts, and a little BluTack affixed to the underside stabilised the unit considering it's lightness and occasional pull from cables. It would be really useful with a 2 channel audio interface to get a total of 5 inputs, or with 2 units, 8 tracks of input 'bounced' realtime into the 2 inputs on the audio interface. That would give your home studio 8 channels of live input for only a cost of €31.40 while you save for an 8 track audio interface. It would be feasible to track a whole drum kit live this way, with only the 2 channel audio interface.
