Features

  • Compact and space saving: 4 channels in 1 RU at 358mm / 14.1’’ depth
  • Minimal “carbon footprint” and operational cost of electricity
  • More watts, less weight: up to 5,000 W in 7.3 kg / 16 lb
  • Switch mode power supply, internally switchable 230/115V nominal
  • Fixed frequency switch mode amplifier output stages
  • Patented amplifier output filters with ripple cancellation network
  • Able to drive 100 V distributed lines directly without the need for transformers 1)
  • Optimized for 4Ω loads, thus ideally matching real-world scenarios in targeted applications
  • AC protection: shuts 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 destructive non-audible, non-musical high frequency signals
  • Short circuit protection: protects the amplifier from short circuit or similar events on the outputs; with automatic protection reset
  • Thermal protection: mutes outputs once output devices reach 75 ºC / 167 ºF; automatic unmute once temperature is down to 65 ºC / 149 ºF
  • Temperature controlled continuous variable speed fan, front to rear airflow
  • Recessed stepped level attenuators

Applications

  • Small to medium-scale systems, portable and installed
  • Stage monitoring
  • Hotels, restaurant and bars
  • Amusement parks, themed entertainment
  • Houses of worship, auditoriums
  • Educational facilities
  • Live and dance clubs
  • Mobile DJ’s
