Powersoft DUECANALI 1604 DSP+D 2-Channel Power Amplifier for Lo-Z and Hi-Z transducers

Powersoft DUECANALI 1604 DSP+D 2-Channel Power Amplifier for Lo-Z and Hi-Z transducersProviding access to all functions yet easily set up, the Duecanali Series is versatile in use. Powersoft's legendary efficency saves valuable energy, keeping both operational cost and carbon footprint at a minimum. The Duecanali 1604 is designed to work with lo Z (from 2 ) and with 70V 100V distributed lines: any mixed impedance output loads can be realized. A fully integrated state of the art DSP yields extensive system management functionality. In

The Duecanali 1604 is designed to work with lo-Z (from 2 Ω ) and with 70V/100V distributed lines: any mixed impedance output loads can be realized.
 
A fully integrated state-of-the-art DSP yields extensive system management functionality. In addition to sound shaping and limiter functions in unique Powersoft style, the DSP hardware and Armonía Pro Audio Suite™ software enable compliance with IEC 60849 for the crucial requirements of sound systems for emergency purposes.

Features

Power supply

• Universal switch mode power supply up to 400V_AC 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 operating range
• Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
• 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 reducing maximum output
• Thermal protection: output stages operating temperature up to 80 °C (176 °F)
• Temperature controlled continous variable speed fan, front to back airflow

General

• Fixed frequency switchmode output stage for high grade sound accuracy
• Compact 1 RU for reduced rack cost and space
• Light weight - for easier racking and shipping: 7 kg (15.4 lbs)
• Standard Phoenix connectors: analog and digital input, audio outputs, alarms and GPIO
• Remotely dimmable inputs 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

• General Purpose Input/Output alarm interfaces:
  • 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 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
