WHAT’S NEXT: I’m still working on my Timex vs Rolex article. Hopefully, if I can publish articles more frequently to spread out the comments, you won’t have to worry about it. As long as you see either of those links, there are newer comments not being shown. It’s not perfect, and sometimes doesn’t work with Internet Explorer or mobile browsers, but clicking the “ Load More…” or “ Loading…” link at the end of the comments should load at least some of the newer posts. More on that in the next ODAC article.Ģ00 COMMENT LIMIT: With some help from friendly blog readers I’ve found a work around for the 200 comment limit. SCHEMATIC: YoYoDyne has received approval from Tenor to release the schematic once. If you don’t have either source powered up you may hear some hum and/or noise due to the floating input. When you unplug the jack the O2 will switch to the ODAC. When a jack (say from a portable player) is plugged into the jack the O2 will disconnect the ODAC and play the external source. O2 + ODAC: As previously discussed, when combined with the O2 and wired to the input jack as shown in the Tech Section below, you can still use the line input jack of the O2. You need some sort of headphone amp like the O2 (the ODAC fits inside), the upcoming ODA, a FiiO E5/E6/E9/E11, etc. ODAC CANNOT DRIVE HEADPHONES DIRECTLY: There still seems to some confusion the ODAC is a headphone DAC by itself.

That’s good news as I can spend more time on the open source DIY Obective Desktop Amplifier (ODA).ĪVAILABILITY: I’m not involved with the manufacturing, sales, or, for that matter, receiving any profit. I still need to publish my final large ODAC article with all the measurements and more technical details, but my involvement is otherwise coming to an end. I’m pleased to report the performance essentially matches the previous prototype I measured in every area and has significantly lower jitter. These are known as “first articles” and are built using the same PC boards and parts as the production boards. GOOD NEWS! I just completed testing the first two ODAC boards from YoYoDyne.
