For mission-critical, multi-zone applications in medium- to large-scale installations, the 8-Channel Ottocanali Series delivers system flexibility, as well as reliable, high-efficiency performance. The Ottocanali is an 8-channel, Class D power amplification platform capable of supplying up to 12,000 W of power at 4 ohms. Designed for multi-zone applications in medium- to large-scale installs, all versions in the Ottocanali Series support any combination of Lo-Z or Hi-Z output connections and include universal switch-mode power supplies with PFC. To maximize efficiency and reliability, the Ottocanali Series also includes patented SRM (Smart Rail Management) technology, which recycles the reactive energy coming back from the loudspeakers, helping lower overall power consumption, reducing heat dissipation, and keeping operating costs to a minimum. All amplifier platforms in the Ottocanali Series feature switchable main/aux signal inputs per channel, mono-bridgeable channel pairs, as well as a wide range of functions such as system control, alarms, GPI/O, and monitoring. The series also includes optional DSP+D versions outfitted with Dante™ by Audinate® inputs. This enables Ottocanali DSP+D amplifier platforms to seamlessly integrate within networking environments and give users a wide range of monitoring and sound-shaping capabilities.
特点
- Universal switch mode power supply up to 400V AC 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
- 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 continuous variable speed fan, front to back airflow
- Fixed frequency switch mode output stage for high grade sound accuracy
