Description

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 a range
Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers

Fully protected circuit design with:

Ac protection: shut down 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 reducing 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

Fixed frequency switchmode output stage for high-grade sound accuracy
Compact size – all models only 1 RU for reduced rack cost and space
Lightweight – for easier racking and shipping: 12 kg (26.5 lbs) according to the configuration
Combo XLR/6.3mm jack Neutrik input connectors with link capability

Lockable set-up by user selectable access key code
Built-in remote control via the RS-485 interface provides full diagnostic, operational setting, and system monitoring
