Features
Power supply
- Redundant universal switch mode power supply up to 400VACÂ 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 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, by 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
General
- Fixed frequency switchmode output stage for high grade sound accuracy
- All models 2 RU for reduced rack cost and space
- Light weight – for easier racking and shipping: 14 kg / 30.8 lbs
- Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
- Remotely switchable double input (main and aux) per channel
Loudspeaker system configuration
- Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
- Switchable 35Hz / 70Hz high pass filter per channel
- Mixed configuration with Lo-Z/Hi-Z systems possible
- Bridged mode, with low impedance, per channel pair
Alarms and GPIO
- General Purpose Input/Output alarm interfaces:
- dangerous DC in the output power signal
- thermal stress
- Configurable alarm contact NC/NO per channel
- Remote AUX input / MAIN input switch
- Remote ON/OFF switch
- PWS OUT connector providing up to 24VDC
