Powersoft K2 Amplifier

The Powersoft K2 amplifier is the perfect choice for musicians and sound professionals who need high-quality sound in a small package. Weighing in at just 8 kg, this amplifier packs up to 4,800 W of power into a tiny form factor. Whether you’re onstage or in the studio, the Powersoft K2 will give you all the power you need to get the job done.

From the Manufacturer

With up to 4,800 W the Powersoft 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 Powersoft 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 Powersoft K3 amplifier – more power without replacing the entire amplifier. Click here to go to the K Series Step-Up page.

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.

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
