Category: SKU: AM/POW/PWS14

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

 The Ottocanali 1204 provides a wide range of system control and monitoring capabilities as well as sound shaping options, and a total of up to 1,280 W output power over 8 amplifier channels for Lo-Z or constant voltage systems, all neatly packed into a single rack unit: As ‘stand-alone’ in corporate boardrooms, or along with Powersoft Duecanali models in the largest setups, the Ottocanali 1204 fits any venue.



The Ottocanali 1204 offers unprecedented versatility and efficiency, also thanks to its very own set of BatFormers®. These are specifically developed, optional plug-in output transformers that can be easily installed through a dedicated lid in the amplifier chassis, and that allow the conversion of any – or all – of the 8 channels into a 70V or 100V constant voltage output.

The Ottocanali 1204 DSP+ETH, includes DSP functionality for all 8 channels, paired with Ethernet connectivity for full control and monitoring through the ArmoníaPlus, also compatible with all other Powersoft K, M, Duecanali Series amplifiers, and Quattrocanali Series(Interface available for MediaMatrix, Crestron, AMXcontrol, Q-SYS and monitoring systems).

Ultimately flexible and safe, with a wide range of system control and monitoring capabilities as well as sound shaping options, and a total of up to 1,200 W output power over 8 amplifier channels for lo-Z or distributed line systems, all neatly packed into a single rack unit. Powersoft’s legendary efficiency saves space and valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum. Ancillary technologies, such as the integrated DSP platform and the super-compact BatFormers®1), both developed specifically for the Ottocanali 1204 DSP, add immense practical value during system design, installation and use, resulting in substantial savings at any level. The Ottocanali 1204 DSP is unprecedented in combining efficiency, performance and adaptability

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 back airflow
