The K20 impresses with up to 18,000 W in single rack space, making it probably the most powerful amplifier at its size.
Ideal for subwoofers requiring relatively high continuous power and ample headroom, the K20 is the unique result of smart design, attention to sound quality, and extremely high efficiency with reliability, portability, and adaptability in mind.
In use worldwide by leading touring and event companies, K Series is preferred among the top ranking system designers, sound engineers, and system techs on the road for making their lives easier, giving them reliable premier-grade power and headroom in the smallest possible package.
Fully digitally controlled and with a serial PC communication port as standard, the K20 DSP+AESOP amounts to a fully integrated, highly sophisticated yet easy to use power source. Including state-of-the-art sound shaping and system management capabilities, remotely controllable via Powersoft’s ArmoníaPlus.
