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
