For mission-critical, multi-zone applications in small- to medium-scale installations, the 8-channel Ottocanali 1204 Series offers unprecedented versatility and ensures reliable, high-efficiency performance. The Ottocanali 1204 is a Class D power amplification platform designed for multi-zone applications in small- to medium-scale installs. Capable of supplying a total 1200W over 8 channels for Lo-Z or constant voltage systems in a single rack unit, the Ottocanali 1204 Series also features optional BatFormers® - specially designed plug-in output transformers that enable the conversion any - or all - of the 8 channels into a 70V or 100V constant voltage output. The Ottocanali 1204 Series offers a wide range of system control, sound shaping, and monitoring capabilities, and features adequate GPI/O, alarms, as well as mono-bridgeable channel pairs and a universal switch mode power supply with PFC. For added versatility, the Ottocanali 1204 DSP+ETH version includes sound shaping functionality, crossovers, filters, limiters, and delay, as well as Ethernet connection, which enables extensive amplifier control, as well as system and load monitoring via PC and Armonía™ Pro Audio Suite™, and is in compliance with the requirements for emergency/alarm system as specified in IEC 60849.
Características
- 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
