Visão geral
The Quattrocanali is a 4-channel, Class D power amplification platform designed for small- to medium-scale installations where system flexibility is a must. Offering the same reliability and renowned audio quality as all Powersoft amplifier platforms, the Quattrocanali Series operates with both Lo-Z and 70V/100V distributed lines or any mix of the two. The Quattrocanali Series also features patented SRM (Smart Rail Management) technology, which recycles the reactive energy coming back from the loudspeakers, helping lower overall power consumption, reducing heat dissipation, and keeping operating costs to a minimum. Quattrocanali DSP+D versions enable extensive amplifier control, as well as system and load monitoring via PC and ArmoníaPlus.

Funcionalidades
- 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
- 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
- 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
