More good News: Khadas new heatsink can fit with VIMs and Tone Board. Convenient for customers to develop and Mold/Enclosure/Case design So that the customized product can evolve from idea to reality ASAP.

Of course, users can enjoy Tone Board via USB-C interface and Tone Board is a ideally choice for audio developers for obvious reasons.

The DNR which let’s hear a wide range and very subtle sounds, meanwhile, the sound field is horizontal and vertical, and the sense of space and layering is like a live concert.

The Khadas Tone Board is a high performance DAC and a bargain price. It is exceptionally well engineered and easily earns my highest recommendation! 

The XMOS USB audio to ensure a rock-solid connection. We selected to use the XMOS XU208 microcontroller for its stability, powerful functionality, and its reliability. You can be sure that the Tone Board will just work when connected to most audio sources, such as computers and mobile media terminals.

The higher the SNR means the clearer the sound in audio system. Generally, the SNR need to be lower than 110 dB in Hi-Res audio system.

The higher the crosstalk separation, the higher the isolation level of the left and right channel so that you can get stunning stereo effects.

Tone Board can output stable enough signals at each frequency point. For the bass, the low frequency sound is enough but not boom and no dryness, and the alto, the person’s Voice of middle frequency is close to the front, the tooth sound is clear and it has the high definition and the degree of separation, finally the treble is not sharp and it’s transparent with depth.

Tone Board has excellent THD+N parameter that means we can barely hear the distortion over the THD+N signal ratio.

We integrated XMOS advanced multi-core RISC architecture microcontroller and ESS flagship 32-Bit stereo mobile audio DAC ES9038Q2M in such a small PCB. And, we choose 3 independent high performance OPA and 4 ultra-low phase jitter oscillator for best noise reduction. The same as you think, each power supply path is powered by an independent, ultra-low noise power supply and the OPA is powered up to ±5.5V. There are a lot of examples of such designs, but in general, we try our best to get better performance through optimal design.
