Duo

The Duo is the dawn of a new area.

This 2 ch class A/B amplifier had to be unique and excessive. Not only in its massive power output, which is on par with large class D amps, but even in its ability to please the audiophile listeners.

                                                           A S/N ratio of 105 dB coupled with a wide frequency                                                            response, will entartain you beyond the human hearing                                                            range.

                                                           No matter which frequency it amplifies, the Duo will                                                            never loose its grasp of the music. Filters with broad                                                            crossover points, matched with vast amplification levels                                                            will control tweeters / mids / subwoofers with accuracy.

                                                           The Duo will never sound breathless given the right                                                            conditions. Remember power is nothing without control.

*In order to get the full power output of the amplifier, it is crucial that your electical system is correctly (over)dimensioned. Failure to upgrading, will constrain the power output & lower the effeciency of the amplifier. In worst case, it can cause damage to the amplifier.
