Reliable and Durable Dual Channel Professional Amplifiers, the U2 Series cover the power range most used in professional audio applications (500~1500Watts). The U2 Series all feature toroidal transformers for reduced weight and low noise output, variable-speed DC fan cooling, Stereo, Parallel, or bridged operation, and balanced inputs via XLR and TRS 1/4" phonejacks. Speaker connections are provided by Speakon^TM connectors. The U2 Series operates in dual channel mode at 4 or 8W or in bridged mode at 8W. Four models provide power outputs at 250, 350, 550 or 750 watts per channel (both channels driven at 4W load).

The single Printed Circuit Board design of the U2K Series eliminates internal wiring that can lead to unreliable operation, especially when the amplifier is transported often in touring or mobile sound applications. On top of this rugged mechanical design is audio designed with the audiophile in mind. These powerful models will amaze you with their punch and transparency. The U2K Series amplifiers are built for medium and small clubs and as side-fills in near-field applications such as in churches, schools, coffee shops, bars, and shopping stores. The U22a and U24a are true 2W models and will deliver average sound pressure level to every corner of a room. They can drive eight 8W speakers using dual channels.
