A method of 100% regeneration of the input AC power is adopted, and stable power is supplied to connected devices with a low impedance output and a large capacity power supply of 1500 VA. Equipped with 5 independent regeneration zones, it is compatible with a wide range of devices from power amplifiers to digital devices. It is a full-scale clean power supply that suppresses noise from the power supply and brings out sound field visibility, instrument separation, and even fine nuances, and is the foundation for the entire system. Unlike conventional models that use large toroidal transformers, etc., a major feature is that a stable power supply environment can be constructed by generating a new AC waveform internally. The large display can display information such as voltage, power consumption, THD, etc., and can be used while checking the power state of the audio system. There is a thin scuff on the top plate.
