Powersoft Ottocanali 8K4 8-Channel Power Amplifier for Lo-Z and Hi-Z Transducers

The Powersoft Audio Ottocanali 8K4, a versatile, dependable 8-channel power amplifier providing up to a total of 8,000 W at 4 Ohms, is great for multi-zone applications in medium to large-scale installs. Ottocanali 8K4 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. The Ottocanali 8K4 features switchable main/aux signal inputs and offers a wide range of system control, alarms, GPI/O and monitoring functions as well as sound shaping options, plus it implements redundant universal switch mode power supplies with PFC and patented SRM (Smart Rails Management) technology. This maximizes reliability, efficiency, and reduces power consumption.
