Powersoft Ottocanali 4K4, Ottocanali 8K4, Ottocanali 12K4 Datasheet
Ottocanali Series
8-Channel High-Performance Power Amplifier with optional DSP and Dante™
For Lo-Z & Hi-Z Installations
Multi-zone venues
Themed entertainment, amusement
parks, shopping malls
Cruise ships
Stadiums, arenas, convention centers
Houses of worship
Theaters, auditoriums, concert halls
Main systems, central or distributed,
lo-Z/hi-Z
Even more exible and reliable, the
new Ottocanali Series includes three
models namely the Ottocanali 4K4, 8K4
an d 12K4 – available with optional DSP
and Dante™ by Audinate
of 12,000 W at 4 ohm, ideal for multizone applications in mid to large-scale
installs.
Ottocanali implements two redundant universal switch mode power supplies with PFC and patented SRM (Smart
Rails Management) technology that
maximizes the efciency.

Powersoft Ottocanali offers a wide
range of system control and monitoring
functions as well as sound shaping options; the DSP version offers extensive
feature set:
Flexible routing/mixing provided by
the internal 8x8 input/output matrix,
allows the user to mix and route
analog and digital I/O.
Input and output IIR, FIR, IIR+FIR
equalizers and raised-cosine lters.
Complete sets of limiters: peak,
RMS voltage, RMS current, and
TruePower™.
Compensation of the speaker
cable losses with Active
DampingControl™ and
LiveImpedance™ load monitoring
Customizable input backup policy
that allows to automatically switch
input source in case of signal failure.
Easy plug-and-play dual redundant
Dante™ ports.
Practical and versatile, 8 channels
for lo-Z or distributed line systems all
neatly packed into a double rack unit:
Directly drives any mixed congura-
tion of low impedance loads and
70 V / 100 V lines.
Implements HPF lter to either
35Hz or 70 Hz congurable per
channel.
GPIO, remote on/off switch and
MAIN/AUX input selection.
Dual redundant universal switch
mode power supply with PFC
(Power Factor Correction) ensure
unparalleled system reliability.
Outstanding low power consumption
and heat dissipation: the ideal
main system in any venue where
performance is priority.
