Powersoft Amplifiers Ottocanali 8K4 DSP+D
Overview
The Ottocanali 8K4 DSP+D is a flexible and reliable 8-channel power amplifier with up to a total of 8,000 W at 4Ω, ideal for multi-zone applications in medium to large-scale installs: Ottocanali 8K4 DSP+D supports any combination of lo-Z loudspeakers, mono-bridgeable channel pairs and 70V/100V Hi-Z distributed lines with no need for output step-up transformers. The Ottocanali 8K4 DSP+D features switchable main/aux signal inputs and offers a wide range of system control, alarms, GPI/O, and monitoring functions as well as sound shaping options.
The Ottocanali 8K4 DSP+D implements universal switch mode power supplies with PFC and patented SRM (Smart Rails Management) technology maximizing reliability & efficiency and reducing power consumption.
New Ottocanali 8K4 DSP+D heralds new and innovative levels of signal processing. Providing flexible routing and mixing, multi-stage equalization with raised-cosine, IIR, and FIR filters, delay up to 2 s in input processing and 100 ms for time alignment, gain and polarity adjustment, crossover, peak limiters, TruePower™ limiters, and Active DampingControl™.
Powersoft’s legendary efficiency saves valuable energy, keeping operational cost and ‘carbon footprint’ at a minimum: the Ottocanali 8K4 DSP+D shines with outstandingly low power consumption and heat dissipation. This dramatically reduces costs from the AC mains supply and air conditioning/cooling systems – not to mention the environmental benefits for a greener planet.

Features
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 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 nonaudible, strong, nonmusical 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 (nonaudio) signals, by reducing the maximum output
- Thermal protection: output stages operating temperature up to 80 °C (176 °F)
- Temperature-controlled continuous variable speed fan, front-to-back airflow
