Features

Power supply

Powersoft legendary universal switch-mode power supply up to 400VAC tolerant with Power Factor Correction
Patented output filter with ripple cancellation network
Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for the USA) socket

Protections

Fully protected circuit design with:

Ac protection: shut down the power supply when AC mains voltage is outside the 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, by reducing the maximum output
Thermal protection: output stages operating temperature up to 80 °C (176 °F)
Temperature-controlled continuous variable speed fan, front-to-back airflow
Temperature forecast with LCD traced historical behavior

General
