The Studio 26 is a USB-Bus Powered 2 input, 4 output Audio/Midi interface. It features phantom power, mic/instrument inputs, and headphone output. Each of the 4 outputs is DC-coupled. DC-coupled outputs are great if you have any gear that has control voltage inputs. The only caveat with the outputs is they produce a voltage of +/-3.5v, so do your homework as to what voltage utility modules are best suited for your needs and interests. I've used this interface for about a year now (home studio electronic music production and one show under its belt); the drivers are great, no hiccups or complaints. Sturdy, durable, and compact little thing and perfect for small spaces and traveling about! Comes with USB cable!
