The Ottocanali 8K4 DSP+D from Powersoft is a powerful eight-channel installation amplifier engineered for high-demand professional audio environments. Built in a compact 2RU chassis and weighing 14 kg, it features a universal switch-mode power supply with Power Factor Correction, tolerant up to 400VAC, along with a patented ripple-cancellation output filter and low inrush limiting to simplify system integration. Advanced cooling with temperature-controlled variable-speed fans and front-to-back airflow ensures reliable long-term performance.

Comprehensive protection systems include AC, clip, DC, VHF, short-circuit, long-term RMS limiting, and thermal protection up to 80°C, safeguarding both the amplifier and connected loudspeakers. The unit supports direct drive of low-impedance loads or 70V/100V high-impedance distributed lines, allows mixed Lo-Z/Hi-Z configurations, and offers bridged operation per channel pair with selectable 35Hz/70Hz high-pass filters for flexible system design.

Powered by a TI C6000 DSP platform with dual 24-bit/96kHz converters delivering 127 dB dynamic range per channel, it provides advanced signal processing including parametric IIR and custom FIR filters, linear-phase and hybrid crossovers, input delay up to 2 seconds, output delay up to 100 ms, Active DampingControl™, and comprehensive TruePower™, RMS voltage/current, and peak limiting. Remote control and monitoring are available through ArmoníaPlus, while integrated GPIO, alarm contacts, AUX/MAIN switching, remote ON/OFF, and a 24VDC PWS OUT connector make it ideal for complex, large-scale installed sound systems requiring maximum control and reliability.
