 The resolution, textures, transparency and expression of sound is greatly affected by how and what power is supplied to your audio devices. Which means a power supply unit affects the sound quality to the entire audio system, and should never be considered “just a power supply unit.”

The sPS-500 is an audio power supply designed specifically for high performance audio. It is built to eliminate noise generated by powered devices as well as to remove noise coming from an AC power source.

Using SOtM’s unique technologies for noise cancellation and sound enhancement, and high quality audio components that are already proven in sound quality, you will hear superior sound with the well-designed sPS-500.

The sPS-500 can easily cope with a wide range of AC power input – the output voltage can change to 7Vdc, 9Vdc, 12Vdc or 19Vdc depending on the power specification of your audio equipment – and the 50W output is flexible enough to be applied to various audio systems. It is also designed to provide more stable power through the input, output, overcurrent and overheat protection circuits.

The rich texture and detailed, luxurious sound created with the technology of the new sPS-500 will create a new listening experience with your audio system. A unique and impressive exterior design also makes the sPS-500 stand out from the crowd. The sPS-500 will help bring your audio system up to the next level.
