Powersoft Ottocanali 8k4 8-Channel Power Amplifier with DSP + Dante

Power supply

• 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 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

General

• Fixed frequency switch mode output stage for high grade sound accuracy
• All models 2 RU for reduced rack cost and space
• Light weight - for easier racking and shipping: 14 kg / 30.8 lbs
• Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
• Remotely switchable double input

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, with low impedance, per channel pair

Digital Signal Processing

• TI C6000 DSP platform architecture
• AD/DA converter: dual 24bit @ 96 kHz Tandem® architecture, 127 dB dynamic range, per channel
• Input/output independent equalizers per channel providing Raised-cosine, custom FIR, parametric IIR: peaking, hi/lo-shelving, all-pass, band-pass, band-stop, hi/lo-pass
• Crossovers: linear phase (FIR), hybrid (FIR-IIR), Butterworth, Linkwitz-Riley, Bessel: 6 dB/oct to 48 dB/oct (IIR)
• Input delay up to 2s and output delay up to 100ms for time alignment per channel
• Active DampingControl™ for cable compensation
• Power limiter (TruePower™, RMS voltage, RMS current) + Peak Limiter

Alarms and GPIO

• NC/NO contacts per channel for alarm notifications
• Remote ON/OFF switch
• Remote AUX/MAIN inputs switch
• PWS OUT connector providing 24VDC

Remote management

• Control and monitoring through ArmoníaPlus
