Redx – Sapphire III BASE

The Sapphire III is a four-channel audio power amplifier that provides 250W (4 ohms) output power per channel. It can also use bridge mode to provide 500W (8 ohm) two-channel output. Unlike Sapphire II, it adds the latest digital audio processing technology and support for Dante digital network audio transmission technology. Sapphire III BASE is a four-channel audio power amplifier that provides 250W (4 ohms) output power per channel. It can also use bridge mode to provide 500W (8 ohm) two-channel output. Unlike Sapphire II, it adds the latest digital audio processing technology and support for Dante digital network audio transmission technology. It uses the latest SSA Technology and digital audio transmission and processing technologies to create:
  • PSM phase modulation technology, zero crossover distortion
  • Single-stage power conversion is equivalent to the direct use of AC mains power, which is one level lower than traditional class D power amplifiers.
  • Two-way energy recovery system to improve power conversion efficiency and effectively reduce the speaker coil voice temperature
  • ZVS, ZCS Soft Switch Technology, Significantly Reduces Switch Heat, Further Improves Conversion Efficiency
  • Overall efficiency up to 90% ultra high
In the past 100 years, the audio power amplifier topology has undergone Class-A, Class-AB, Class-D, etc., but it has always been a compromise between efficiency and sound quality. To date, SSA Technology has achieved Sapphire III BASE to Class-A sound quality levels with 90% overall system efficiency with its advanced and precise audio modulation technology, single stage power conversion, bidirectional energy recovery and soft switching technology. Really achieved "high efficiency and good voice!" Sapphire III BASE uses the latest digital audio processing and transmission technology, and targeted optimizations have been made. The efficient, reliable, and optimized application design, combined with its Class-A sound quality level, make it widely used in fixed installation systems.
