O Quattrocanali foi pensado para funcionar com lo-Z (desde 2 Ω) e linhas distribuídas de 70V/100V: podem ser processadas quaisquer cargas de saída de impedância mista. As versões DSP da Série Quattrocanali conferem um controlo e monitorização profundos de todos os sinais através do ArmoníaPlus, para que o som possa ser adaptado às necessidades do cliente. Esta Plataforma amplificadora é também fiável em aplicações críticas, tais como em sistemas de deteção de incêndio, graças à sua fonte de alimentação que permite um funcionamento fiável mesmo quando ligada a uma UPS. Os serviços MyPowersoft estão disponíveis para este produto. Alimentação Alimentação universal com correção do fator de potência (Power Factor Correction) "Low Inrush Limiting" para redução de picos na corrente elétrica, eliminando a necessidade de sequenciadores de potência caros Cabo AC destacável, com conector IEC C19/22. 2 (16A para Europa, 20 A para EUA) Proteções Projeto de circuito com proteção completa, com: Proteção AC: desliga a chave de força quando o AC estiver com voltagem fora da faixa de operação Limitador de Clip: evita que formas de onda com clips atinjam os alto-falantes, e ao mesmo tempo mant

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.

Funcionalidades
- 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
