Projects and circuits, directly or indirectly related to Audial devices
AYA 5 revision B is the 2024 release of the famous DAC project. It is a non-oversampling converter based on the TDA1541(A), and it includes an asynchronous USB with up to 384 kHz capability, an S/PDIF, and optional direct inputs, and a discrete output stage without feedback.
Summer 2023 brings the third version of the Audial USB interface board. And just like its predecessors, it is a limited series, available only for preordering.
According to the feedback we got recently, the interest in the USB interface and AYA projects may have re-emerged. And in case we find it adequate, we will go and release one or both of these projects again, as limited series.
The AYA 4 was a very nice project, and it apparently remained on your radar way after the originally produced quantity was sold out. So we will make it one more time.
AYA 4 is 2018 AYA release, with all the features of previous AYA II DACs, and completely changed, now no-compromise, 192 or 384 kHz capable asynchronous USB stage. AYA 4 can be used as usual stereo DAC, but its USB input stage can be also made as 4 channel interface.
Audial USB interface second release. Now offered as both module and ready made device.
Audial quality USB interface. At one side it connects to PC via USB port, and on the other it outputs “raw” PCM signal, in simultaneous data or I2S form.
Asynchronous USB Audio Class 2.0, galvanic isolation, two oscillators, and reclocked simultaneous data output. With U.FL output connectors it would be adequate companion to AYA II 2014 or DS board, and of course the great possibility to connect PC to Model S MkIII.
As announced a few months ago, we have another run of AYA II. This run, marked as DS, includes one update with respect to AYA II 2014: synchronous DEM clocking circuit is now more completely integrated, so it is not optional but integral part of this AYA II project.
As an extension of original AYA II 2014 DIY edition offer, here is the second turn of AYA II 2014 orders.
Everything related to AYA II 2014 DIY edition building, parts and possible tweaks can be asked, discussed or shared at this page.
As a result of initiative by several TDA1541A fans at diyaudio.com, AYA II DAC may re-appear in 2014.
The OPA861 based output stage for TDA1541A, as used in the AYA II DAC, was posted here one month ago and, according to feedback, authentic and ambitious DIY spirit is still around. So I am reposting now one old article that was once available at pedjarogic.com.
