Hi,

Small Pre-amplifier with complete analog stage controlled by digital Micro-controller and information on Alphanumeric Display. Soon will be mounted after completing the design of PCB´s, and assembly and final adjust on firmware of the Micro. Already tested in isolated parts during develop.
The Phono and DAC card are removable slots to easy replace by other developments on the way.

Caro Ave,

Apesar do post ser antigo e as informações são quase nenhuma, achei interessante pelo design das placas e das poucas features que vc apresentou.

Teria alguma informação adicional sobre esse projeto?

Obrigado.

Hi, Volume/Balance/Bass/Tremble/Channel Selection -> all analog controlled by a microprocessor and alphanumeric display for user info.
I reduce the number of wires on control by using a serial bus that enables multiples slaves to be controlled by one or more masters.
This simplifies the design and mounting

Final specs when fully assembled

Very nice!

The PCB was made with very good quality. Your PCB have a good design for my eyes.

I waiting  anxiously the final prototype. I think that the other friends of forum also.
