Description
Ultimately flexible and safe, 8-channels power amplifier ideal for multi-zone applications in small to mid-scale installs.
Ottocanali 1204 provides adequate GPI/O, alarms, Lo-Z loudspeakers and Hi-Z distributed lines compliancy, as well as mono-bridgeable channel pairs in a compact 1 RU cabinet. 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 Suite™, making the Ottocanali 1204 DSP+ETH compliant with the requirements for emergency/alarm system as specified in IEC 60849.
Ottocanali 1204 DSP+ETH Features:
- Power supply
- 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
- Protections 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 continuos variable speed fan, front to backairflow
- General
- 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
