  • Powersoft DIGAM K20 18,000 Watts @ 2 Ohms 2 Channel Power AmplifierDIGAM K Series has become the flagship of Powersoft's technologies, ranking in the Top Class amplification of the global pro audio market. It represents a new milestone of switch mode amplification providing incredible power in 1 rack unit with the lowest weight and highest efficiency. It's sonic performances set a new target for professional audio market.


    • Advanced switch-mode worldwide operating power supply technology for high performance and compact sizee
    • Power Factor Correction PFC for extremely low mains consumption and extremely wide mains operating range
    • Variable speed fan for low noisee
    • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
    • XLR female / 6.3mm Jack Neutrik style input connectors with link capability
    • Built-in defeatable Clip limiters for each channel
    • LCD matrix interactive displayy
    • Digital gain-attenuator control
    • User selectable maximum output power for each channel
    • User selectable maximum mains current draw
    • Comprehensive-user friendly front panel display menu
    • Fully protected circuitry design including DC, infrasonic, high frequency, thermal overload and short circuit

    Protections circuitry

    DC protection: protects against infrasonic signals
    VHF protection: protects the loudspeakers against strong very high frequency non-musical signals above the audible range.
    Thermal protection: prevents the amplifier from being overheated. The protection indicators on the front panel are switched on, as a warning, before the protection process is initiated.
    AC protection: shuts down the power supply if the line voltage is outside the operating voltage.
    Clip limiter: prevents severely clipped waveforms from reaching the loudspeakers, whilst maintaining full peak power.
