8-Channel Power Amplifier for Lo-Z and Hi-Z transducers
- 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
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.
Ultimately flexible and safe, 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 board rooms, 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.
Compliant with IEC 60849, and on par with the Duecanali Series, the Ottocanali 1204 DSP+ETH matches the crucial requirements for sound systems for emergency purposes.
Powersoft’s legendary efficiency saves space and – more importantly – valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum. Ancillary technologies, such as the super-compact BatFormers®1), developed specifically for the Ottocanali 1204, add immense practical value during system design, installation and use, resulting in substantial savings at any level. The Ottocanali 1204 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 continous variable speed fan, front to back airflow
