HELIX E40 Esprit
4-channel tube amplifier with active highpass, adjustable from 40 Hz - 200 Hz, 4 double-triodes as driver, see-through to check the tubes; all connectors are placed just on one side
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
