8-channel power amplifiers with up to a total of 12,000 W at 4Ω - ideal for multi-zone applications in mid to large-scale installs. All versions in the Series feature aux signal inputs and adequate GPI/O, as well as mono-bridgeable channel pairs. Moreover, they all can be 4, 5, 6, 7 and 8-channel configured.

The 2 RU models, namely the Ottocanali 4K4, 8K4 and 12K4, have two 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. Note: new models available from 2nd quarter of 2013.

The Ottocanali 1204 DSP+ETH version offers sound shaping functionality, crossovers, filters, limiters, and delay. Ethernet connection enables extensive amplifier control, system and load monitoring via PC and Armonía Pro Audio SuiteTM, making the Ottocanali 1204 DSP+ETH compliant with the requirements for emergency/alarm system as specified in IEC 60849, just like the Duecanali DSP+AESOP models. Interface available for MediaMatrix, Crestron and AMX control and monitoring systems.

Ottocanali is entirely made in Italy, and must undergo the same stringent quality control measures before shipping as every other Powersoft product, including the 48-hour burn-in test procedure. Naturally, Ottocanali is backed with our standard 4-year warranty.
The M Series maintains the high professional class from small to medium applications of installed sound, stage monitors and portable sound.
