This portable DJ system (Atra) features the world's first real standalone and portable design. There are few products in the market with a similar concept, but none of them are true in meaning of standalone (requires PC connectivity) or portable (over-sized, heavy or requires AC power). These products are so-called "DJ equipment" and used to control the sound at clubs or parties. Generally, those traditional DJ equipment in the market are huge, heavy and expensive, thus are limited to specific users only. However, Atra is designed to achieve portability so that anyone can bring it anywhere, such as events, parties and performances. It comes with dual touch panel LCDs, physical rotary knobs and a slider bar for remarkable performance. Users can easily handle two sound sources by using the dual touch panel LCDs, and can feel analog sensibility by using the physical knobs and the slider bar. The core competency of Atra is that it is not a subset of traditional DJ equipment, but rather a complete functional product that can be an alternative to the existing DJ equipment.

• Standalone design.
