Hello, I'm trying to modify the input gain/pad of Behringer DI DI20 (dual direct box), I apreciate if someone has a link to the service manual/schematic, Thanks in Advance!

Hello, Nitro.
I assume you want to use this (well, let's just be polite and say crappy) DI box to connect DJ equipment to your sound system. If so, don't waste time with modifying it. Get one of those isolating transformers, like ART DTI or similar.

hello paleeman

thanks for the advice but I already possess 2 boxes, use to connect guitars, basses, keyboards, etc., only I need to modify a pair of resistances to reduce its excessive sensibility.
and the -20dB pad it is also excessive and it introduces too much hiss

OK, I have no idea how it is laid out on the board, but the switch has three positions. Basically one position is open, one position puts 10k across the balanced pair, and the third position puts 1k across it. If you explore with an ohm meter, you should find those resistances.

R9, R7 are for channel 1 and R10, R8 are for channel 2.

Just a thought. Good luck with the modification.

sweet a dual 10k pot should make the input pad adjustable!
