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 dynamically adjusts internal voltage rails based on real-time audio output demands. Powersoft’s SRM significantly reduces energy consumption during lower audio output conditions, improving overall efficiency.
Quattrocanali DSP+D versions enable extensive amplifier control, as well as system and load monitoring via PC and Armonía Plus.

Features
- 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
