Powersoft Quattrocanali QC8804 4-Channel Power Amplifier with DSP + Dante

Power supply

• 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
• 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 switch-mode 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

Settings

• Built-in defeatable clip limiters for each channel
• Digital gain-attenuator control
• Defeatable gate selection for each channel
• User selectable gain/sensitivity
• User selectable maximum output power for each channel
• User selectable maximum mains current draw
• Lockable set-up by user selectable access key code
• Built in remote control via the RS-485 interface provides full diagnostic, operational setting and system monitoring

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 and Monitoring

Via Software:

• Control and diagnostics monitoring via ArmoniaPlus
• 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)
