EgoSys U2A - USB Audio Interface with 24-bit converters

EgoSys is always on the edge of the new wave of professional audio industry. This time, it's USB! These days, we are all about to be rollin' into the world of USB. EGOoSYS is again just one step ahead of others to introduce a 24-bit USB Audio Interface. Its studio quality performance and features lend themselves to various applications of professional desktop music production.
Highest quality 24-bit AD/DA converters provide unmatched sound quality with exceptionally low noise. Take a listen and you will immediately notice the difference in the sound quality. Digital or analog, not all audio interface cards are made the same. If you are a professional or in need of a professional quality USB audio interface, you have made a sound investment in Waveterminal U2A.
U2A provides 1/4" phone jacks for use with -10dBv nominal level consumer audio equipment. Unlike some audio cards that deliberately boost their output levels to give you a false sense of audio quality, U2A gives you a true indication of your levels. Nothing's added or taken away unless you intend to do so. If you need to adjust levels, digital level adjustment is provided for analog inputs and outputs.
U2A offers 3 stereo input options (coaxial, optical and analog) that you can select one of your choice at a time while the output signal is available on all 3 output formats at the same time.
U2A supports 3 multiple sampling rates (32, 44.1, 48K) with real-time hardware sample rate converter - this is U2A's unique function that you cannot find from any other digital audio interface.
U2A can also function completely separate from the computer - any incoming audio signal (either analog or digital) can be sent out through three different output ports (analog, coaxial, optical).

The Swissonic USB Studio /D is the perfect solution for every home recording environment.

It provides inputs and outputs for most of the equipment to be used in a typical home setup like two microphones (phantom powered), two HI Z instruments, four stereo line inputs for keyboards and MIDI expanders, tape input (with switchable phono preamp!), S/PDIF input and output (optical and coaxial), tape output, monitor output and headphone output. Each input's and output's volume can be adjusted individually. The built in USB interface connects the USB Studio with your favorite computer (PC, Macintosh) and Software (all standard audio applications). Each input source can be enabled for recording.

There's no need for a sound card anymore… somehow clever!
