A versatile, dependable Analog 8-channel/Digital [Dante] 16 x 8-channel power amplifier delivering up to a total of 4,000 W at 4 Ohms of output power, Powersoft's Ottocanali 4K4 DSP+D works great for multi-zone use in small to mid-scale installations. It offers support for any combination of lo-Z loudspeakers, mono-bridgeable channel pairs, as well as 70V/100V Hi-Z distributed lines, with no need to employ step-up output transformers. It's equipped with switchable main/aux signal inputs, and provides a wide variety of system control, GPI/O, alarms, and monitoring functions, along with sound-shaping options. It uses redundant universal switch mode power supplies with PFC and patented SRM (Smart Rails Management) technology, and thus delivers maximum reliability, efficiency, and reduced power consumption. Additionally, it comes equipped with Dante functionality; including Dante redundant networking via (2) Rj45 ports on the rear panel:

  • Primary/ETH1 is the Primary network port
  • Secondary/ETH2 is the Secondary network port

Heralding a contemporary, innovative level of signal processing, the Ottocanali 4K4 DSP+D's provides non-boolean mixing and routing as well as multi-stage equalization with raised-cosine, IIR and FIR filters, up to 2 s of input processing delay, and 100 ms for time alignment, gain and polarity manipulation, crossover, peak limiters, TruePower™ limiters, plus Active DampingControl™.

Powersoft's renowned efficiency can conserve valuable energy, keeping both operational cost and 'carbon footprint' at a minimum: the Ottocanali 4K4 DSP+D really shines with exceptionally low power consumption and heat dissipation, which dramatically reduces costs from the AC mains supply and air conditioning/cooling systems – not to mention environmental benefits for a greener planet.

Applications:

  • Multi-zone venues
  • Themed entertainment, amusement parks, shopping malls
  • Cruise ships
  • Stadiums, arenas, convention centers
  • Houses of worship
  • Theaters, auditoriums, concert halls
  • Main systems, central or distributed, lo-Z/hi-Z
