Hello there,

A friend of mine passed away and left me his Nava. We had already used it several times and it was working fine, except the accent. PSU was lost so I bought a new one which I think is OK.
Sequencer is running, all seems fine but I got no sound at all except "clicks" corresponding to my step trigs when I put my mixer's gain at a very high level. Same behaviour on the master and individual outs. No mutes, volume is OK...

I plan to install the SH Mux Boards for accent improvement.

Firmware is 1.028.

I'm not a DIYer and have not much skills with soldering, schematics and components.

Maybe I'm missing something?

I also noticed that the potentiometers weren't soldered:

Thank you!

That is not the correct PSU. The one you have is 15V AC/DC. What you need is 15V AC/AC. Start by changing that and then see what it sounds like first.

Wow I haven't noticed that, my bad, I've just bought a new one, I'll let you know! Thank you!

Hello, the problem was the PSU, all is working except accent. My Nava is 1.02 board, is that normal that I haven't got any accent at all given that I don't have the SH Mux boards (yet)?

I noticed another problem with the master output:
Drums are a little overdriven with a strange behaviour on the clap sometimes, like a phaser, etc. I removed R469 and R470 but same issue.
With individual outs, drums are perfect, really deep.

Kick on master:

Kick on individual:

You can clearly hear the difference.

And different waveforms:

LT https://i.ibb.co/NC5CKpX/LT-nava.png

etc...

Thanks.

I think I maybe having the same issue.

Here's a capture of my Kick Drum waveform from my oscilloscope.
