K2

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+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 Armonía Pro Audio Suite™ (Interface available for MediaMatrix, Crestron, AMX, Q-SYS control and monitoring systems).

Power supply

  • Advanced switch-mode worldwide operating power supply technology for high performance and compact size
  • Power Factor Correction PFC for extremely low mains consumption and extremely wide mains operating range
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers

Protections
Fully protected circuit design with:

  • Ac protection: shut down power supply when AC mains voltage is outside operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long term limiter: protects the loudspeaker against steady long term rms (non audio) signals reducing maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature controlled continous variable speed fan, front to back airflow
  • Temperature forecast with LCD traced historical behaviour

General
