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, by 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
General
- Fixed frequency switch-mode 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
Settings
- Built-in defeatable clip limiters for each channel
- Digital gain-attenuator control
- Defeatable gate selection for each channel
- User selectable gain/sensitivity
Alarms and GPI/O
- NC/NO contacts per channel for alarm notifications
- Remote ON/OFF switch
- Remote VCA control per channel
Remote Control & Monitoring
Via Software:
- Attenuation (from 0 dB to 26 dB)
- Max output voltage
- Output and gain reduction metering
- Diagnostics (temperature, fans, …)
Via Hardware:
- Attenuation (from 0dB to 26dB)
- High-pass filters (35Hz, 70Hz)
- Lo-Z/Hi-Z/70V/100V output selection
- Adjustable gain (from 26dB to 35 dB)
