Final PCB layout for Clavier 101 Kit version.

We are at final home stretch for launching Clavier 101 kit version first. Some changes in circuit as well as components based on the result of device testing-sound tuning and Radio frequency sensitivity and etc.

Currently material list is being prepared. Expect to release the kit version in late Sep.

Hi all,

It has been a long time since the last posting. We have worked on final sound tuning after radio field test in collaboration with a tuner module supplier.

Several issues were fixed

1. RCA output level
2. Gain control for differential amplification
3. Input voltage calibration and optimization-heat sink
4. Radio tuning sensitivity
5. Change of 2 DACs to PCM1793 from PCM 1794
6. Adoption of ultra low ESR capacitor(Panasonic FR) as decoupling
7. Adoption of OLED display for kit version

A kit version is expected to be released in late Sep. and the Final setup box will take more time and we will keep you updated.
Thanks for interest.

Cheers
