My wife and I use this for our podcast. Our vocal goes into two channel and the 3-4 stereo is being used by her for listening music.
The sounds is very good but it will sound like digital when it is distorted due to high peak volumes.
Pros: You can use 4-mono channel in live and recording. At this price, you can't find like this.
There are multiple features in this product, that is why I bought this.
Cons: That only I found missing is the control of Attack and Release. But at this price point. It is fair enough.
Lastly, this unit gets hot it needs external fan.
