The Pre-amp board has the ability to amplify the signal, it is recommended metal shield is installed, the input signal shielded wire, or outside interference will be induced noise, such as your hand close to or touch the potentiometer and other body sensor will go in, do not take the wood box. Compatible ALPS16 and ALPS27 2 specifications of the potentiometer.
1/ PCB size 70*64mm, conductive lower resistance, better sound, extreme appearance.
2/ Full DC circuit, 0-100KZ flat frequency, timbre extension, detail is very good.
3/ High-quality power supply, using the best linear power supply LM317 LM337, ELNA 4300uf filter capacitor, brown black gold decoupling God.
4/ Gilded IC seat, IC transpose easy to replace.
5/ Used in all German resistance no sense of resistance VIS cylindrical sound better than DALE.
6/ Can be used with all aluminum shield case, make less noise, quieter background.
7/ Compact, can rely directly potentiometer screws directly to the board to the chassis panel.
8/ The supply voltage of the board is from double 12V to double 18V.
