No. A digital to analog converter (DAC) is used to convert digital audio signals (e.g. on a CD or computer) to analog ones for driving amplifiers and speakers. You're perhaps thinking of a double-conversion UPS or power conditioner, which converts electricity to DC, filters it, charges a battery (in the case of a UPS), then converts it back to AC to power your devices.
- Relys 10y agoOk thanks for clarifying. I was thinking of a feature on a motherboard I recently purchased: "USB DAC-UP provides clean, noise-free power delivery to your Digital-to-Analog Converter. DACs can be sensitive to fluctuations in power from the other USB ports, which is why USB DAC-UP takes advantage of an isolated power source that minimizes potential fluctuations and ensures the best audio experience possible." I've also had to use a 5v step up converter to provide a filtered power source for the camera on my FPV drone I built. I can see why an Audiophile would want filtered voltage supply if they had money to burn I guess.
- nitrogen 10y agoYeah, the isolation in this Japanese case is similar in intent to the isolation your motherboard advertises, but on a much larger scale. It's the isolation that matters. Every mobo has a DAC if it has audio, but not every mobo has an isolated power supply for the DAC.
- cellularmitosis 10y agoRather than employing isolation, you could also use filtering. In the case of the article, $10k would buy you an unbelievably effective 60hz band-pass filter...
