**Overview**
The **Powersoft Duecanali 4804 DSP+** is designed for ultimate flexibility, capable of handling both low-impedance (from 2 Ω) and 70V/100V distributed line applications, allowing for any mixed impedance output load configuration. Featuring Powersoft’s renowned efficiency, it minimizes energy consumption and reduces operational costs and environmental impact. The integrated DSP offers comprehensive system management with advanced sound shaping, limiting functions, and the ability to meet IEC 60849 standards, crucial for emergency sound systems. Additionally, the DSP+ model integrates AES67 digital audio networking for seamless signal routing. **MyPowersoft services** are available for this product.

**Features**
