Offering up to a total of 12,000 W at 4 Ohms, the Powersoft Audio Ottocanali 12K4 DSP+D is a dependable and versatile Analog 8-channel/Dante 16-channel power amplifier that's ideal for multi-zone use in medium to large-scale installations. It supports any combination of lo-Z loudspeakers, mono-bridgeable channel pairs, and 70V/100V Hi-Z distributed lines without the need for step-up output transformers. It 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 12K4 DSP+D features innovative signal processing and supports 2 redundant Dante by Audinate® digital streams.

The introduction of the Ottocanali 12K4 DSP+D heralds a contemporary, innovative level of signal processing, offering non-boolean routing and mixing, multi-stage equalization with raised-cosine, IIR and FIR filters, delay of up to 2 s in input processing and 100 ms for time alignment, gain and polarity adjustment, crossover, peak limiters, TruePowerâ„¢ limiters, plus Active DampingControlâ„¢.

It uses redundant universal switch mode power supplies that include PFC and patented SRM (Smart Rails Management) technology that maximizes reliability and efficiency, plus reduces power consumption.

Powersoft's legendary efficiency conserves valuable energy, minimizing both operational cost and ‘carbon footprint’: the Ottocanali 12K4 DSP+D shines with remarkably low power consumption and heat dissipation; This dramatically reduces costs from the AC mains supply and air conditioning/cooling systems – not to mention the benefits to the environment for a greener planet

Powersoft Audio Ottocanali 12K4 DSP+D Features:

Power supply

  • Redundant 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 reducing maximum output
    • Thermal protection: output stages operating temperature up to 176 °F (80 °C)
    • Temperature controlled continous variable speed fan, front to back airflow

General

  • Fixed frequency switchmode output stage for high grade sound accuracy
