Powersoft K2 DSP 2-Channel High Performance Power Amplifier
With up to 4,800 W the K2 is the "smallest" amplifier in K Series. Built on the same technologies and features as present in the bigger models, it makes a full-fledged member of the amplifier line that changed the face and direction of the professional audio amplification market.
Only 8kg/17.6lbs light, the K2 is the ideal companion for where space, weight, and uncompromised sound quality matter.
Per Step-up card a K2 can be upgraded to become a K3 – more power without replacing the entire amplifier.
In use worldwide by leading touring and event sound 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 size. Fully digitally controlled and with a serial PC communication port as standard, the K2 is also available with KDSP board and KAESOP Ethernet/AES3 interface: the K2 DSP+AESOPamounts 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 Power supply Protections General Settings Monitoring Digital Signal Processing* Remote management*
