Long term limiter: protects the loudspeaker against steady long term RMS (non audio) signals, by reducing maximum output. Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset. VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals. DC protection: protects against infrasonic signal at the outputs. Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output. AC protection: shut down power supply when AC mains voltage is outside operating range. Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA)socket. 
Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers. Patented output filter with ripple cancellation network. Main systems, central or distributed, subwoofers,hi-Z/lo-Z. This Amplifier Platform is ideal for 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. The amplifier also features the lowest thermal dissipation in the industry, reducing the need for external cooling devices. Plus, Quattrocanali offers patented SRM (Smart Rails Management) technology for maximum efficiency of the system and drastically reduced power consumption in any load and usage condition. DSP QUATTRO 4 REVIEW INSTALL
This 4-channel install amplifier is equipped with high-end digital signal processing and supports the Dante™ digital audio networking architecture.ĭesigned to operate with Lo-Z (from 2 Ohms) and 70V/100V distributed lines or any mix of the two, this power amp delivers in-depth control and monitoring via Armonìa, so tailoring the sound and managing the system can be done by a remote, decentralized location. Achieive excellent sound quality and reliability with Powersoft's Quattrocanali 4804 DSP+D.
