Power HELIX B4 Precision 4 channel made in germany Dijual kondisi bekas normal masih belom pernah service The Helix B4 is a powerful, dynamic top-of-the-class amplifier that is controlled by its own integrated software. This integrated managing software (IMS) makes the read-out of all relevant data possible. Therefore the amplifier provides optimized working in terms of power, current and temperature. The music signal is of course analog processed to reach the best sound and dynamic results. The sophisticated active crossover allows a perfect adjustment of all connected speakers and subwoofers. The B4 has an integrated temperature controlled cooling fan that can be switched off if desired. The turn-on temperature as well as the maximum power of the cooling fan can be adjusted by two separate controls. The connection of an external fan is possible.
