we are proud to introduce our Plain series DAC’s to the audio DIY community.
Finally it’s here. A high quality I2S DAC below the 10,- Euro barrier.
A perfect match in price, size and quality with a lot of single-board-computers out there.
Only 42 x 17 mm and can be mounted nearly everywhere.
We are offering 3 different levels:
Equipped with a PCM5100 from TI (SNR 100 dB) and a dedicated LDO for the analog part.
This is a perfect match if you want to connect the output to an amp or music system that have their own volume control.
PlainDAC+ is populated with a PCM5121 (SNR 106 dB) and does also feature a separate LDO.
Additionally this one adds integrated hardware volume control and access to GPIO4 of the DAC.
This one is the most advanced one. PCM5142 (SNR 112 dB) is used and again a dedicated LDO.
There is also volume control build in and additionally you have the possibility to make use of the build in DSP.
Currently we are working on a pice of SW that makes it possible to use two of this for a digital stereo crossover.
Some basic EQ functions are also on it’s way.
If you are using a Raspberry: all three are compatible with the hifiberry drivers which are integrated in the official kernel.
For everybody else we have created a little cmdline application that allows you to startup and control the DAC’s directly from userspace. You just need to check that generic I2S output is enabled.
We are located in Germany and are shipping to a lot of countries.
