Overview

Quattrocanali 4804 offers the traditionally amazing sound quality and reliability of all Powersoft products.


The patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduce power consumption in any load and usage condition. Quattrocanali features the lowest thermal dissipation in the industry, reducing the need for external cooling devices.


Quattrocanali is designed to operate with Lo-Z (from 2 Ω) and 70V/100V distributed lines or any mix of the two.


DSP+D versions of the Quattrocanali grant in-depth control and monitoring via Armonìa, tailoring the sound and managing the system can be done by a remote, decentralized location.


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

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


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, 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
