HELIX DB TWO Dark Blue

2-channel amplifier with active crossovers

Colour: silver

        ▪ RMI (Real Mixed Input) for forming an optimised
            mono-summation signal from the left and right channels
        ▪ Integrated electronic crossover
        ▪ 5.0 volt / 8.0 volt inputs for connection to any signal source
        ▪ Switched power supply unit for output performance of
            generously dimensioned proportions within the
            smallest spaces
        ▪ Intelligent noiseless on/off switching for the prevention
            of pop noise, even when various units are interconnected
        ▪ Smart protection electronics for overheating,
            overvoltage and voltage drop
        ▪ Separate speaker protection circuit with current
            limitation for speaker short circuiting, cable contact
            with the car body, low impedance and faulty connection
        ▪ ADC Anti Distortion Choke (current-compensated
            input device) for noise suppression
        ▪ 1% accurate components for perfect sound quality
        ▪ 24 carat gold-plated solid connection terminals
            for loss-free signal and power transmission
        ▪ CPS (Colour Protection System) diagnostics system
        ▪ Temperature-optimised heatsink of SiAl alloy for the
            best possible consistency of performance
