Some AV amps may contain one per channel so if your amp can play 7.1 audio, it might have eight DAC chips. Some sound cards, and most off-board DACs, contain two of them, or for each of the stereo channels. In short, anything that needs to convert digital audio to analog has a DAC.Ī DAC, in its basic form, is merely a chip. If you have an AV receiver, that has a DAC, as do optical disc players (CD, DVD and Blu-Ray). You’ve got one in your computer (it’s one or two chips on the sound card), in your smartphone, your iPod, or any other device that plays music. (DAC chips aren’t new, but DACs as standalone devices have only become common in the past five years or so.)ĭACs are present in many devices. This relatively new element in the hi-fi audio chain converts the digital stream of audio from your computer, or other digital source, into analog music that your amplifier then amplifies before sending it to speakers. A reader wrote me recently asking my about DACs digital-analog converters.
