Powersoft – Q4804

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 continuous variable speed fan, front to back airflow
•    Temperature forecast with LCD traced historical behavior
General
    •    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: 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
•    User selectable maximum output power for each channel
•    User selectable maximum mains current draw
•    Lockable set-up with user selectable access key code
•    Built-in remote control via the RS-485 interface provides full diagnostic, operational setting, and system monitoring
Monitoring
•    Hardware monitor available for fast local diagnostic
•    Load impedance measurement for each channel
•    Output power measurements for each channel
•    Mains voltage and current measurements
•    Downloadable log file of functional fault events with time-related trace
Remote management
    •    Control and monitoring through Armonía Pro Audio Suite™
