- Review-uri (0)
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
- 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
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: 7 kg (15.4 lbs)
- Standard Phoenix connectors: analog and digital input, audio outputs, alarms and GPIO
- Remotely dimmable inputs 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
- Mixed configuration with Lo-Z/Hi-Z systems possible
- Bridged mode low impedance per channel pair
Alarms and GPI/O
- General Purpose Input/Output alarm interfaces:
- dangerous DC in the output power signal
- thermal stress
- Configurable alarm contact NC/NO per channel
- Remote ON/OFF switch
Digital Signal Processing
- TI C6000 DSP platform
- AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture
- Input/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filters
- Delay up to 100 ms for time alignment
- Active DampingControl™ for cable compensation
- Peak, RMS voltage, RMS current, TruePower™ limiters
Remote management
- Control and monitoring through Armonía Pro Audio Suite™
- Dedicated Web App
