Glensound Mini Cub USB Audio Interface

The Glensound Mini Cub is a small USB audio interface for PCs and Macs that provides high quality audio interfacing for audio ingest to the PC whilst at the same time being able to monitor the stereo return audio.

There is a 3 pin XLR input.  This is selectable from line, mic, or mic with 48V phantom power.  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 4 segment LED indicates the incoming signal.  This single input is delivered to both channels of the USB connection.

There is a mini USB with a Neutrik water and dust proof screw connection for connecting to your PC or Mac.  This link also powers the Mini Cub as it is USB powered and requires no separate power source.

Stereo return audio from the USB connection is available for monitoring from the 6.35mm jack socket.  There is a front panel pot for headphone level control. There is also a front panel pot control that allows a mix between the send and return audio so that the operator can achieve the perfect mix.

The Mini Cub is built for broadcast, in a heavy duty housing, with audio specifications to match.  It has internal digital signal processing and micro controllers for system control, with the digital audio at 24bit 48kHz, and an equivalent input noise (EIN) of 121dB at line up.

Unit dimensions are 79 x 93 x 36 mm.

The Mini Cub is very trimmed down on features, focusing on being a high quality USB audio interface that manages the variation of incoming audio levels very well.  It allows a single input connection and stereo return monitoring from the PC.  All this in a small robust case that is powered from the USB connection.
