Differential Preamplifier 8×2. Project Balanced Pre-Amplifier
Another **UPDATE** July 28th
Boards are all populated, not tested yet just waiting for a ribbon cable to show up that connects the selector board to the main board.
Bench all setup to start SMD soldering.
Some parts soldered on the first day, then I took a break.
Input selector board.
All done !
**UPDATE** July 25th
Parts are here !! WOOT !!
I stumbled app-on a really nice & simple pre-amlifier. Contacted the maker ( In Canada ) and did some chatting and research, came to the conclusion and ordered the boards. It’s a fully SMD Balanced Pre-amp, so i get to spend a few hours placing one part at a time soldering one part at a time on the boards.
So far I just have the new shiny boards, parts are on their way. Reading over the very well laid out manual, is going to make this build fun and enjoyable. After I have it all built & tested, I’ll be researching around for a custom chassis or draw up and get my own made.
I have also choose not to use the PCB mounted XLR in & out connectors. Instead I’m going to be buying chassis mountable Neutrik ones..
Few pictures ( from their site ) and a direct link to the product.
