Overview

Exceptionally flexible and safe, the Ottocanali 1204 provides a wide range of system control and monitoring capabilities, and a total of up to 1,280 W output power over 8 amplifier channels for Lo-Z or constant voltage systems, all neatly packed into a single rack unit: Stand-alone in corporate board rooms, or along with Powersoft’s Installation models in the largest setups, the Ottocanali 1204 fits any venue. The Ottocanali 1204 offers unprecedented versatility and efficiency, also thanks to its very own set of BatFormers®. These are specifically developed, optional plug-in output transformers that can be easily installed through a dedicated lid in the amplifier chassis, and that allows the conversion of any - or all - of the 8 channels into a 70V or 100V constant voltage output. MyPowersoft services are available for this product.

Features

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
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
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
Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
Switchable 35Hz / 70Hz high pass filter per channel
Mixed configuratio with Lo-Z/Hi-Z systems possible
Bridged mode low impedance per channel pair
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
