Mini USB Audio Interface - 

The Mini Cub is a small USB audio interface for PCs and Macs that provides high quality audio interfacing for audio to the PC whilst at the same time being able to monitor the stereo return. The input features Glensound's Referee compressor/limiter system to avoid any input clipping. There is a front panel pot for adjusting input level control and a 4x LED for the incoming signal. This single input is delivered to both channels of the USB connection. There is a mini USB connection with a water- and dust-proof screw. This link also powers the Mini Cub and requires no separate power source. It has internal digital signal processing and micro controllers for system control, with the digital audio at 24-bit & 48kHz sampling rate, and an equivalent input noise (EIN) of 121dB at the line. The Mini Cub is designed for broadcast applications, but also a home studio.
