8000W/8-channel Flexible Amplifier

Description

Powersoft Amplifiers Ottocanali 8K4

Overview

The Ottocanali 8K4 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 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 implements universal switch mode power supplies with PFC and patented SRM (Smart Rails Management) technology maximizing reliability & efficiency and reducing power consumption.

Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum: the Ottocanali 8K4 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 benefits to the environment 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 the USA) socket

Protections

Fully protected circuit design with:

  • Ac protection: shut down the 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

General

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

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, with low impedance, per channel pair

Alarms and GPIO

  • Configurable alarm contact NC/NO per channel
  • Remote AUX input / MAIN input switch
  • Remote ON/OFF switch
  • PWS OUT connector providing up to 24VDC
