Powersoft Duecanali DC1604 2-Channel Amplifier with Dante + DSP

Power supply

• Powersoft legendary universal switch-mode power supply up to 400VAC tolerant with Power Factor Correction
• 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

Protections

Fully protected circuit design with:

• Ac protection: shut down power supply when AC mains voltage is outside the 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 switchmode 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

Loudspeaker system configuration

• Direct drive either 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 low impedance per channel pair

Alarms and GPI/O

• NC/NO contacts per channel for alarm notifications
• Remote ON/OFF switch
• Remote VCA control per channel

Digital Signal Processing

• TI C6000 DSP platform
• 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 & Monitoring

Via software:

• Control and diagnostics monitoring via ArmoníaPlus
• Dedicated WebApp

Via Hardware:

• Attenuation (from 0dB to 26dB)
• High-pass filters (35Hz, 70Hz)
• Lo-Z/Hi-Z/70V/100V output selection
• Adjustable gain (from 26dB to 35 dB)
