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.
Engineered around uptime
Powersoft has always been very focused on energy saving and the use of the Power Factor Correction (PFC) has been a trademark for improving performance and containing mains current draw and consumption.
In any amplifier output stage, the efficiency is a function of the difference in the output voltage delivered to the load and the rails voltage delivered from the power supply.
