Codex
Frequently asked questions


I've had trouble playing my portable player through my Codex, why is that?

Unfortunately, not all devices with optical outputs conform to the S/PDIF standard. The Codex does comply with the standard so in certain cases non-conforming players will not work well with the Codex. If you have this problem contact us. We have alternate firmware for the Codex which should solve this issue.

My Codex gets pretty warm on top, is that normal?

Yes, this is perfectly normal. The heat comes from the Diamond output stage and pure analog power supply which we use in the Codex. This creates more heat, but it is a big part of the reason it sounds so good!

Does the Codex work with four-conductor headphone jacks for headphones with in-line microphones and volume controls?

No, the nature of the multi-function 3.5mm headphone output creates a conflict when the additional contact on one of these lifestyle cables is used. Please use only standard, 3-conductor, 3.5 mm stereo headphone jacks for single-ended mode or twin 3.5 mm headphone jacks with the correct tip-ring-sleeve configuration for balanced mode.
