### **Powersoft Duecanali 1604 DPS - Specifications**

**Power Supply:**
- Universal switch mode up to **400VAC** tolerance with **Power Factor Correction (PFC)**.
- Patented output filter with **ripple cancellation network**.
- **Low inrush limiting** reduces AC inrush current, eliminating the need for expensive power sequencers.
- Detachable **AC mains cable** with **IEC C19/22.2** (16A for EU, 20A for USA) socket.

**Protections:**
- **AC protection**: Shuts down power supply when AC mains voltage is outside the operating range.
- **Clip limiter**: Prevents severely clipped waveforms from reaching loudspeakers while maintaining peak power output.
- **VHF protection**: Protects loudspeakers from strong, non-musical high-frequency signals.
- **Short circuit protection**: Protects the amplifier from short circuits and other stressful events, with automatic protection reset.
- **Long-term limiter**: Protects loudspeakers from steady, long-term RMS signals (non-audio), reducing maximum output.
- **Thermal protection**: Protects output stages at temperatures up to **80°C** (176°F).
- **Temperature-controlled, continuous variable-speed fan**, with front-to-back airflow.

**General:**
- Fixed frequency **switch-mode output stage** for high-grade sound accuracy.
- Compact **1 RU** design for reduced rack cost and space.
- **Lightweight**: 7 kg (15.4 lbs) for easier racking and shipping.
- **Standard Phoenix connectors**: Analog and digital input, audio outputs, alarms, and GPIO.
- Remotely dimmable inputs per channel.

**Loudspeaker System Configuration:**
- Direct drive for **low impedance loads** or **70V/100V Hi-Z distributed lines**.
- Switchable **35Hz / 70Hz high-pass filter** per channel.
- **Mixed configuration** with Lo-Z/Hi-Z systems possible.
- **Bridged mode** for low impedance per channel pair.

**Alarms and GPI/O:**
- **General Purpose Input/Output (GPI/O)** alarm interfaces for:
   - Dangerous DC in the output power signal.
   - Thermal stress.
- Configurable alarm contact (NC/NO) per channel.
- **Remote ON/OFF switch**.

**Digital Signal Processing:**
- **TI C6000 DSP platform**.
- **AD/DA converter**: Dual **24-bit @ 48 kHz** with **Tandem®** architecture.
- **Input/output independent equalizers** per channel: PEQ, raised cosine, shelving IIR filters, and custom output **FIR filters**.
- **Delay** up to 100 ms for time alignment.
- **Active DampingControl™** for cable compensation.
- **Peak, RMS voltage, RMS current**, and **TruePower™ limiters**.

**Remote Management:**
- Control and monitoring through **Armonía Pro Audio Suite™**.
- Dedicated **Web App** for remote access.
