4000W/8-channel Flexible Amplifier
Overview
TheOttocanali 4K4is a flexible and reliable 8-channel power amplifier 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.
The Ottocanali 4K4 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.
The Ottocanali 4K4 implements universal switch mode power supplies withPFCand patentedSRM(Smart Rails Management) technology maximizing reliability & efficiency and reducing power consumption.
Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum: the Ottocanali 4K4 shines with outstandingly low power consumption and heat dissipation. This dramatically reduces costs from the AC mains supply and air conditioning/cooling systems – not to mention the benefits to the environment for a greener planet.

Features
Power supply
- Redundant universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
- Patented output filter with ripple cancellation network
- Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
- Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket
ProtectionsFully protected circuit design with:
- Ac protection: shut down power supply when AC mains voltage is outside operating range
- Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
- DC protection: protects against infrasonic signal at the outputs
- VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
- Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
- Long term limiter: protects the loudspeaker against steady long term RMS (non audio) signals, by reducing maximum output
- Thermal protection: output stages operating temperature up to 80 °C (176 °F)
- Temperature controlled continous variable speed fan, front to back airflow
General
- Fixed frequency switchmode output stage for high grade sound accuracy
- All models 2 RU for reduced rack cost and space
- Light weight - for easier racking and shipping: 14 kg / 30.8 lbs
- Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
- Remotely switchable double input (main and aux) per channel
Loudspeaker system configuration
- Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
- Switchable 35Hz / 70Hz high pass filter per channel
- Mixed configuration with Lo-Z/Hi-Z systems possible
- Bridged mode, with low impedance, per channel pair
Alarms and GPIO
- General Purpose Input/Output alarm interfaces: dangerous DC in the output power signal
- thermal stress
Configurable alarm contact NC/NO per channel Remote AUX input / MAIN input switch Remote ON/OFF switch PWS OUT connector providing up to 24VDC

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.
