The most versatile model due to an attractive mix of features, size and output power, making the K3 an outstanding value. It is built on same technologies as every other K Series model, and indeed, the K3 produces the same great sound quality, no matter what type of loudspeaker it is connected to.

Fully digitally controlled and with a serial PC communication port as standard, the K3 is also available with KDSP board and KAESOP Ethernet/AES3 interface: the K3 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).

    • 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, while maintaining full peak power.
