HELIX E400 Esprit

4-channel tube amplifier with high- and lowpass, adjustable from 40 Hz - 250 Hz, 4 double-triodes as driver, see-through to check the tubes; all connectors are placed just on one side and has more power than its predecessor

Colour: black

         ▪ RMI (Real Mixed Input) for forming an optimised
            mono-summation signal from the left and right channels
        ▪ Integrated electronic crossover
        ▪ 4.0 volt / 6.0 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
        ▪ Printed circuit board copper-plated on both sides for maximum
            quality of power and signal transmission and protection against vibrations
        ▪ 1% accurate components for perfect sound quality
        ▪ 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
