Aprašymas

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.

Another version, the Ottocanali 1204 DSP+ETH, includes DSP functionality for all 8 channels, paired with Ethernet connectivity for full control and monitoring through the Armonía Pro Audio Suite™, also compatible with all other Powersoft K, M, D, Q and particularly the Duecanali Series amplifiers (Interface available for MediaMatrix, Crestron, AMXcontrol,Q-SYS and monitoring systems).

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.

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
