OTTO 1204

Amplificateur 8 canaux installation fixe

150W/4 ohms
Powersoft universal switch mode power supply up to 400VAC tolerant
External controls features
Fully protected circuit design

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

Fully 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 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

Fixed frequency switchmode output stage for high grade sound accuracy
Compact 1 RU for reduced rack cost and space
Light weight – for easier racking and shipping: 5-11 kg (11-24.3 lbs) depending on number of BatFormers
Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
Remotely switchable inputs (main and aux) per channel

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
