Powersoft Advanced Tech Ottocanali 1204-ETH
8-Channel Amplifier

OUR PART #  Ottocanali 1204 DSP+


Ultimately flexible and safe, 8-channels power amplifier ideal for multi-zone applications in small to mid-scale installs.

Ottocanali 1204 provides adequate GPI/O, alarms, Lo-Z loudspeakers and Hi-Z distributed lines compliancy, as well as mono-bridgeable channel pairs in a compact 1 RU cabinet. The Ottocanali 1204 DSP+ETH version offers sound shaping functionality, crossovers, filters, limiters, and delay. Ethernet connection enables extensive amplifier control, system and load monitoring via PC and Armonía Pro Audio Suite™, making the Ottocanali 1204 DSP+ETH compliant with the requirements for emergency/alarm system as specified in IEC 60849.

Ottocanali 1204 DSP+ETH 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 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 80 °C (176 °F)
    • Temperature controlled continuos variable speed fan, front to backairflow
  • General
    • Fixed frequency switchmode output stage for high grade sound accuracy
    • Compact 1 RU for reduced rack cost and space
    • Light weight - for easier racking and shipping: 5-11 kg (11-24.3 lbs) depending on number of BatFormers
    • Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
    • Remotely switchable inputs (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 configuratio 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
    • Remote AUX input / MAIN input switch
    • Remote ON/OFF switch
    • PWS OUT connector providing up to 24VDC
  • Digital Signal Processing
    • Analog Devices® ADAU 1702 DSP architecture
    • AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture, 100 dB dynamic range, per channel
    • Input/output independent equalizers per channel providing PEQ, shelving IIR filters
    • Delay up to 16 ms for time alignment
    • Active DampingControl™ for cable compensation
    • Peak and RMS limiters
    • Remote management
    • Control and monitoring through Armonía Pro Audio Suite™
    • Interface available for MediaMatrix, Crestron, AMXcontrol, Q-SYS andmonitoring systems
