Crisp sounding, high end 4-channel amplifier platform

Quattrocanali 1204 offers the traditionally amazing sound quality and reliability of all Powersoft products.

The patented SRM (Smart Rails Management) technology allows to maximize the the efficiency of the system and drastically reduce power consumption at 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 work with lo-Z (from 2 Ω) 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

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 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
