The U-Phoria is a great little interface. With 2-ins and 2-outs, the Input levels are controlled by 2 individual channel Gain Pots. There is a Direct Monitor Selector on the front and on the far right, a Volume Pot. This volume pot controls both the L/R output, and also the Headphones, so be cautious when switching between the 2. A 48v Phantom Power switch is also available on the back, allowing you to use Condenser Mics, along with a USB port to connect it to another device (PC/MAC).
Depending on your requirements, this 2x2 could be too small for your needs, however, it could also be just perfect. I am using this as my interface between my Laptop, and my PA System in the studio for playback only purposes, and I don't need it to do anything else. An overcomplicated or larger interface would just be a waste of money.
A point to mention, is that it doesn't add or take away any sound. It is clean. Some interfaces add colouring to the sound, making it more bassy, or toppy, both of which, in a studio environment are bad.
If you are a bedroom musician/engineer looking for something small, simple and clean, then look no further :)
I would recommend this product.
