Redx – Sapphire III

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. 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. 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. Until today, SSA Technology has achieved Sapphire III's Class-A sound quality with 90% overall system efficiency with its advanced and precise audio modulation technology, single-stage power conversion, bi-directional energy recovery and soft-switching technology. Truly "efficient sound!" The application of the latest digital audio processing and transmission technology has enabled Sapphire III to achieve a new level of efficiency and sound quality. It is highly efficient, lightweight, reliable, and flexible, combined with its Class-A sound quality, making it widely used in system integration projects such as small entertainment shows and multi-purpose halls.

Marani – MDA4-2000PS

MDA4-2000PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x1700W @ 4 ohms and 4x2320W @ 2 ohms, or able to drive 70V Constant Voltage Lines. MDA4-2000PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x1700W @ 4 ohms and 4x2320W @ 2 ohms, or able to drive 70V Constant Voltage Lines. Designed to meet the most demanding portable and fixed installation sound systems, it provides a full set of value added features such as high output power, efficient cooling system, on board DSP and USB/Ethernet for monitoring and control via PC software. MDA4-2000PS includes a highly efficient Switch Mode Power Supply, which provides power to the output stages. The 4 output stages use the well-proven Class D module-full bandwith PWM modulator obtaining ultra low distortion, high efficiency and also equipped with a full set of circuit protections. Furthermore the Clip/Limiter function provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold, in addition to the efficient heat dissipation system and Over-Heat protection which themselves ensure uncompromised reliability. MDA4-2000PS is more than just an amplifier. It is also a capable and sophisticated loudspeaker processor, thanks to its powerful MARANI® DSP running 96 kHz / 24 bit [ 96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. It offers 4 channels of slope up to 48dB/Oct IIR HP/LP crossover filters, or up to 512 taps FIR filters[FIR coefficients can be imported as .txt/.csv file from external application] , RMS compressor, parametric Eqs , alignment delay and white/pink noise internal generator, everything needed to optimize a loudspeaker system.
