PCB Quality audio design Balanced unbalanced lines II


I can do it but i want someone with real experience in audio design so no mistake of rebuilding pcb its needed as prototypes are expensive.

The design comprise an umbalanced line to balanced, in the same pcb an balanced to unbalanced line, all have to work at 12 dc volts.

I add the .brd board for connector placing as must much an allready made case for this pcb, must be two iqual pcb spaced 5mm i just show one so must be same at the other side but spaced 5mm.

Even i give you eagle file for reference i want it in altium, protel so i could modify.

PCB can be done at double side.

Connectors used are : nc3fah-0 y nc3mah, RCA and jacks.

Its very important that "hum" noise level is the lower posible thats the reason to make this.

This are examples:

Its very easy but i want someone really with experience, able to make something for very good quality audio and working at 12volts, maybe you need to design a power pcb to convert those 12 to the needed voltage.

I expect price arround 100 dollars as is a simple project design low component count and may be done in 2 hours for someone that have allready done this before.

Any questions, please fell fre to ask.
