FAQs

Converting analog audio to digital audio and vice-versa can seem confusing, but understanding the basics can take you a long way. Here are some of the most frequently asked questions on the internet concerning optical to 3.5 mm.

Is optical better than 3.5 mm?

Yes. The sound quality is much better. Digital audio is very complex and is able to sound much richer and deeper than simple analog. Thus, we don’t recommend converting digital optical to 3.5 mm.

How do I convert optical to aux?

Aux is always a 3.5 mm cable. If you’re wondering how to convert optical connection to 3.5 mm or aux, simply use a digital to analog converter (DAC) and plug your optical coaxial cable into the side of the DAC labeled “output.”

Is 3.5mm digital or analog?

3.5 mm will always represent an analog audio source. To convert it, buy a 3.5 mm to optical cable and a digital-to-analog converter.

Is USB analog or digital?

USB is digital. Therefore, any audio passing from an analog sound source into USB must be passed through a converter.

Is digital audio out the same as optical?

Essentially, yes, though the two are slightly different. Whereas your sound system with digital audio sends digital audio out, it does so along a fiber link optical cable. Thus, digital audio out is to optical as analog audio out is to aux. To convert your optical audio to analog, you’ll need an optical audio cable to 3.5 mm and an optical to 3.5 mm adapter like a digital-to-analog converter.
