The inputs are ideal if you are a DJ and need a small portable interface for live performance. Tascam also added a pair of unbalanced stereo RCA inputs. Given a choice, most people would probably prefer balanced TRS outputs. Instead of having balanced TRS stereo outputs, you get unbalanced RCA stereo outputs. To the right of the back panel is where we have a few exceptions to the standard layout.

The direct monitoring switch is for zero-latency monitoring through your headphones. In the middle of the back panel are two switches for direct monitoring and input selection. When used with a computer, the US-1x2HR is USB bus-powered, so a USB Type-C connector is on the back. There’s a Kensington security lock, which might be the most underused feature of any interface, but it’s still better to have the option. Again, from left to right, we have a 5 V DC connection, which is used to power the interface when used with a tablet. If we go through the back panel, it’s pretty standard for the most part, but there are a couple of exceptions. Finally, you get a 1/4″ headphone jack with volume control. First, you have your line out level knob that controls your monitor outputs. The last section on the front panel is all about monitoring. The TRS input has the same layout of gain control and two LED indicators. Next, you have a TRS input that is switchable between line level and instrument level.
