The Powersoft Audio Ottocanali 8K4, a versatile, dependable 8-channel power amplifier providing up to a total of 8,000 W at 4 Ohms, is great for multi-zone applications in medium to large-scale installs. Ottocanali 8K4 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 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 comes with switchable main/aux signal inputs and provides a wide range of system control, alarms, GPI/O, and monitoring functions, along with sound shaping options, plus it implements redundant universal switch mode power supplies with PFC and patented SRM (Smart Rails Management) technology. This maximizes reliability, efficiency, and reduces power consumption.

Powersoft's legendary efficiency offers valuable energy savings, keeping both operational costs and 'carbon footprint' at a minimum: the Ottocanali 8K4 really shines with remarkably low power consumption and heat dissipation for dramatically reduced costs from the AC mains supply and air conditioning/cooling systems – not to mention the benefits to the environment 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

Powersoft OTTOCANALI 8K4 Features:

Power Supply

  • Redundant universal switch mode power supply up to 400VAC tolerant with Power Factor Correction (PFC)
  • 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 (16 A 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 continuous variable speed fan, front-to-back airflow

General

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

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 low impedance per channel pair

Alarms and GPIO

  • General Purpose Input/Output alarm interfaces:
    • Dangerous DC in the output power signal
    • Thermal stress
  • Configurable alarm contact NC/NO per channel
