Powersoft K3 DSP+AESOP

Aprašymas

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.

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 K3 is also available with KDSP board and KAESOP Ethernet/AES3 interface: the K3 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 Armonía Pro Audio Suite™ (Interface available for MediaMatrix, Crestron, AMXcontrol, Q-SYS 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
