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

  • 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

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


  • Fixed frequency switchmode output stage for high grade sound accuracy
  • Compact size - all models only 1 RU for reduced rack cost and space
  • Light weight - for easier racking and shipping: 8 - 12 kg (17.6 - 26.5 lbs) according to configuration
  • Combo XLR/6.3mm jack Neutrik input connectors with link capability
  • AES3 digital input*


  • LCD matrix interactive display
  • Comprehensive-user friendly front panel display menu
  • Built-in defeatable clip limiters for each channel
  • Digital gain-attenuator control
  • Defeatable gate selection for each channel
  • User selectable gain/sensitivity
  • User selectable maximum output power for each channel
  • User selectable maximum mains current draw
  • Lockable set-up by user selectable access key code
  • Built in remote control via the RS-485 interface provides full diagnostic, operational setting and system monitoring


  • Hardware monitor available for fast local diagnostic
  • Load impedance measurement / display for each channel
  • Output power measurements / display for each channel
  • Mains voltage and current measurements / display
  • Downloadable log file of functional fault events with time related trace
  • Smart Card settings, parameters and upgrades functionality

Digital Signal Processing*

  • Analog Devices SHARC® DSP architecture
  • AD/DA converter: dual 24bit @ 96 kHz Tandem® architecture, 127 dB dynamic range, per channel
  • Input/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filters
  • Delay up to 1 s for time alignment
  • Active DampingControl™ for cable compensation
  • Power limiter (TruePower™, RMS voltage, RMS current) + Peak Limiter

Remote management*

  • Control and monitoring through Armonía Pro Audio Suite™
  • Interface available for MediaMatrix, Crestron, AMXcontrol, Q-SYS and monitoring systems
