Power supply
Powersoft legendary universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
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 USA) socket

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

General
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: 7 kg (15.4 lbs)
Standard Phoenix connectors: analog audio outputs, aux supply, alarms and GPIO
Remotely switchable double input (main and aux) per channel
