Nava Last Update: Accent improvement
Posted: Sep 26th, '17, 06:54
Dear Diyer,
After spent lot of time testing different TR909s and tried to find the best solution to improve ACC response on the Nava we finally found it.
We designed a small board to replace IC114 and IC111.
This board is a simple multiplexer with amplifiers (two TL074s) as sample hold. With this mods we can have now very accurate accent response.
Here are the boards:



I know what you are thinking : "The components are SMD, it' s hard to solder...".
Totally wrong, it's very easy taking your time and with the right tools.
Have a look on those tutorials : https://learn.adafruit.com/smt-prototyp ... ng-an-soic
https://www.sparkfun.com/tutorials/96.
The Mouser BOM for the needed part to build both boards is available here.
All Diyer that already built the Nava will receive a free set of two boards (availability: October the 16th 2017). Add your name and order number on this sheet and as soon as we get the board ready it will be sent to you
