Audiophonics ES9028Q2M

A dedicated version for the Allo Kali

Adapter, Allo Kali and Raspberry Pi 3 not included

This version of our reference DAC ES9028Q2M has a GPIO port on the top and not below. It is thus compatible with the famous up-sampler ALLO KALI by I2S jumpers clad in argentsor our horizontal offset KALI offset. This new form factor also allows numerous combinations for the classic HiFi boxes of horizontal shape and in particular the integration to our Audiophonics Rasptouch box.

Audio quality always bluffing

Like its predecessors, the ES9028Q2M delivers truly exceptional sound performance with components selected to ensure the most accurate and clean playback. Thus, it supports sampling rates up to 32bit 768kHz. Based on proven technologies, the 32bit Hyperstream offers a wider range of dynamics while drastically reducing the jitter which could cause distortion.

A stand-alone system

Like its predecessors, the ES9028Q2M adapts perfectly to the Raspberry Pi in order to offer a complete, flexible and high performance DAC. This converter innovates on the other hand by offering a real hardware control, also allowing it to operate in any autonomy, via its I2S input. In addition, driver installation is no longer required to enable the DAC to operate. These only come in addition to bring you a software management of your device.

An advanced analog output

Integrating two NJM 2114 AOPs powered 12V on the board corresponding to the ESS technical diagrams, the last AOP NJM 2114 buffer finalizes the analog output stage, to ensure an optimal reproduction.

DietPi Compatible

Our I-SABRE ES9028Q2M DAC is 100% compatible with the Open Source DietPi solution. This optimized solution allows you to install absolutely everything you need, no more, no less. Computer skills (SSH) are required to correctly program this solution. Click on the following logo to discover their site and their solutions to download.
