8-Channel Power Amplifier for mid to large-scale installs
8-channel power amplifiers with up to a total of 12,000 W at 4 ohm – ideal for multi-zone applications in mid to large-scale installs.
All versions in the Series feature switchable main and aux signal inputs per channel, adequate GPI/O, alarms, Lo-Z and Hi-Z output connections as well as mono-bridgeable channel pairs. This 2 RU model, implements two redundant universal switch mode power supplies with PFC and patented SRM (Smart Rails Management) technology that maximizes the efficiency of the system as well as drastically reduces power consumption.
The Ottocanali 4K4 is a flexible and reliable 8-channel power amplifiers with up to a total of 4,000 W at 4Ω, ideal for multi-zone applications in small to mid-scale installs. Ottocanali 4K4 supports any combination of lo-Z loudspeakers, mono-bridgeable channel pairs and 70V/100V Hi-Z distributed lines with no need for output step-up transformers.
