Overview Opto Bass NPB12Overview Opto Bass NPB12
For over 50 years musicians and home HIFI audiophiles have known that vacuum tubes are the best electrical device for sound quality. Unfortunately tube amplifiers are hot and heavy and not always reliable, tubes burn out. In recent years many amp manufacturers have replaced tubes with IC Op-amps and solid state transistors . The benefit was small size and efficiency but the sound quality suffered. They are not as musical as vacuum tubes.
Now we present a new Bass amplifier the Opto Bass PB12
The Opto Bass NPB 12 has been designed and built by people who have their own experience with bass sound and quality very seriously. That is why this product was designed with Discrete FET (Field Effect Transistor). The sound of FET is far better than the ICs opamps sound because the FET operates in a manner somewhat analogous to vacuum tubes.
More over the Opto Bass NPB12 is combined with our custom design 12 speaker VINTAGE ND12B200. This 200 Watts neodymium magnet speaker with special paper cone for Bass tone make a warm and fat Bass sound and reduced the weight of speaker.
This Opto Bass NPB12built with the most care in order to meet all professional standards.
Our goal was not only to design an amp which sounds fantastic and is easy to operate, but also to build it in such a way that it will serve you loyally for many years to come. Since this amplifier is lightweight it is easy to carry to every place.
