Beschreibung

    Discover the SPL Show SP 4.900, a sturdy 4-channel amplifier presented by Hertz. With its powerful ADC power amplifier, it achieves an impressive 85% efficiency and can also be combined with OEM head units thanks to its Universal Speakers Simulator. Its ultra-compact format and protective IP55 aluminum casing not only make this device robust, but also enable installation without a cooling fan. Another advantage: power cables, inputs and outputs are sealed so that they are resistant to oxidation. Easy calibration thanks to centrally located crossover filters and controls rounds off the profile of this 4-channel amplifier.
