1200W/8-channel Flexible Amplifier with DSP

Powersoft 8ch
Routing Channel
DSP on Board


The Ottocanali 1204 DSP, includes DSP functionality for all 8 channels, paired with Ethernet connectivity for full control and monitoring through the ArmoníaPlus. Stand-alone in corporate board rooms, or along with Powersoft’s Installation models in the largest setups, the Ottocanali 1204 DSP with Ethernet fits any venue.

Compliant with IEC 60849, the Ottocanali 1204 DSP matches the crucial requirements for sound systems for emergency purposes.

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


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


  • Fixed frequency switchmode output stage for high-grade sound accuracy
  • Compact 1 RU for reduced rack cost and space
  • Lightweight – for easier racking and shipping: 5-11 kg (11-24.3 lbs) depending on the 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
  • Built-in defeatable clip limiters for each channel
  • Mixed configuration with Lo-Z/Hi-Z systems is 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 ArmoníaPlus
  • Interface available for MediaMatrix, Crestron, AMX, Q-SYS, and monitoring systems
