1200W/4-channel Flexible Amplifier with DSP
Overview
Quattrocanali 1204 DSPoffers 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 versions of the Quattrocanali grant in-depth control and monitoring via ArmoníaPlus, 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.

Features
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
ProtectionsFully 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
General
- 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
Settings
- Built-in defeatable clip limiters for each channel
- Digital gain-attenuator control
- Defeatable gate selection for each channel

- AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture
- Input/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filters
- Delay up to 100 ms for time alignment
- Active DampingControl™ for cable compensation
- Peak, RMS voltage, RMS current, TruePower™ limiters
Remote Control and MonitoringVia Software:
- Control and diagnostics monitoring via ArmoníaPlus

Engineered around uptime
Powersoft’s DSP implements a complete audio management system that provides a unique level of control and can be used to set the tone of any space.
In any amplifier output stage, the efficiency is a function of the difference in the output voltage delivered to the load and the rails voltage delivered from the power supply.
Controlling and monitoring of a Powersoft amplifier can be done through ArmoníaPlus.
Power Sharing enables part of the power to be shared across all output channels so that it can be used where it is needed the most.
Our current line of amplifier offers Dante™ either as standard or as an option on any model, for audio over IP networking.
With modern systems growing larger in size, the resistance that is added by lengthy cable runs starts to become an issue.
