This DIY module based on a DAC I2S ESS ES9038Q2M offers many possibilities of use in a compact card format. It has I2S, SPDIF Coaxial and Optical inputs and a RCA Stereo output as well as a 3.5mm jack. On the component side, this DAC module includes a 100MHz master clock making it compatible with many DSP cards on the market. Among the options available, it is possible to change the original AOP 5532D mounted on a DIP8 bracket to adapt the sound reproduction of the DAC to its listening.

Configurable digital filters & integrated controls

Thanks to its 100MHz digital master clock, it is sufficient to input an I2S DATA, LRCK and BCLK signal from a USB to I2S interface, for example, to obtain a DAC of a formidable quality. This DAC also has Coaxial and Optical SPDIF inputs that can be configured via the module's DIP Switch..

In addition, the module includes 3 control buttons. The VOL + and VOL - buttons are used to adjust the volume. It is also possible to add an external potentiometer on this module (sold separately). A short press of the MODE button switches to Mute mode and a long press of the same button selects the active input. LEDs on the card indicate the active input.
