HK Audio Powersoft X4 4 kanaliga helivõimendi

‌4-channel Benchmark Amplifier with DSP and optional Dante™

Overview

Powersoft X4 innovates and evolves the concept of the amplification platform through the integration of a worldwide compatible power-box and a full feature DSP inside the power amplifier.

The complete digital audio signal management system based on ARM Cortex A-8 processor and TI C6000 DSP platform heralds new and innovative level of signal processing, providing non-boolean routing and mixing, multi-stage equalization with raised-cosine, IIR and FIR filters, delay up to 2s in input processing and 100ms for time alignment, gain and polarity adjustment, crossover, peak limiters, TruePower™ limiters and Active DampingControl™.

The power supply permits worldwide AC acceptance and direct connection to any regional power line configuration: it is now suitable to Single Phase, Bi-Phase or Three Phase operation from 85 VAC up to 440 VAC without the need of manual selection. True Three Phase load balancing is directly achievable by the unit without any complex load assignment in the power distribution system design.

Features

Power supply

• 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 continuous variable speed fan, front to back airflow
  
• Temperature forecast with LCD traced historical behavior

General

• Flexible routing/mixing provided by the internal 4x4 input/output matrix, allows the user to mix and route analog and digital I/O.
  
• 4 input channels with physical analog and digital AES3 connectors.
  
• Optional 16-in/8-out redundant Dante™ connection provide maximum flexibility.
  
• Improved reliability thanks to the customizable input backup policy that allows to automatically switch input source in case of signal failure.
  
• Complete user interface integrated into ArmoníaPlus.
  
• Wi-Fi remote monitoring through mobile devices.
