Powersoft QUATTROCANALI 1204 DSP+D 4-Channel Amplifier
Powersoft QUATTROCANALI 1204 DSP+D 4-Channel Amplifier
Quattrocanali is designed to work with lo-Z (from 2 O) and with 70V/100V distributed lines: any mixed impedance output loads may be realized. DSP+D versions of the Quattrocanali grant in depth control and monitoring of all the signals via Armonìa, so that the sound may be tailored to suit the customer's needs. This Amplifier Platform can also be trusted in mission critical applications, such as fire alarm systems, thanks to the cleverly engineered power supply that allows reliable operation even when connected to a UPS.

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

  • 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

  • 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

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