It is a TiVo for radio.

The "RR" stands for Radio Recorder. It records radio onto a hardisk for time shifting. It can also do internet radio and audio streaming. The best part is that it is for you car! It has 2x50watts output plus 1 pre-amp output.

My Stupid Guess:

The outlaws have combined the popularity of CD-RW technology and the die hards love of vinyl records to create the world's first LP-RW! That's right a vinyl disk recorder that you hook to your computer through USB 2.0. Just imagine going to the computer store to pick-up a spool pack of 50 blank vinyl records.

RR = Record Records
2150 = USB 2.0 with 1 pack of 50 blank records included free of charge.
