OTTOCANALI 1204 DSP

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, 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
• Compact 1 RU for reduced rack cost and space
• Lightweight – for easier racking and shipping: 5-11 kg (11-24.3 lbs) depending on the 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

Loudspeaker system configuration

• Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
• Switchable 35Hz / 70Hz high pass filter per channel
• Built-in defeatable clip limiters for each channel
• Mixed configuration with Lo-Z/Hi-Z systems is possible
• Bridged mode 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

Digital Signal Processing

• Analog Devices® ADAU 1702 DSP architecture
• AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture, 100 dB dynamic range, per channel
• Input/output independent equalizers per channel providing PEQ, shelving IIR filters
• Delay up to 16 ms for time alignment
• Active DampingControl™ for cable compensation
• Peak and RMS limiters

Remote management

• Control and monitoring through ArmoníaPlus
• Interface available for MediaMatrix, Crestron, AMX, Q-SYS, and monitoring systems
