Nepos first Test > No Signal

[Nepo]

Hello Dimitri,
I sold out cable 15/16 (Ground) and 25/26 and connect it direct with the piezo.

15 outer ring - and 25 inner cycle - no signal
16 " 26 " no signal

I try other combinations no signal

What do you mean with "continuity between one of the ground pins on the board " and 15/16 ?

[dmitri]

To check for "continuity" means to check that there is no break between ground on the board and the ground wires. There should me zero resistance between the ground on the board and the ground wires.

... good tip, one of my testcable is broken!

MD lives... I got a signal!

To check all jacks , I connected my testpiezo direct on ground P15/16 and the soldingpins on the jacks.

All is fine even pin 6 (Aux7R) have a permanent deflection on VU without any hit on the piezo.

It is an internal adjustment or a wrong connection?

[dmitri]

Without anything connected there should be no signal coming from MegaDrum or VU meters activities on the LCD. If there is, then you have another problem somewhere.

[Nepo]

Hello, I check all jackconnections with my testpiezo, direct on the solderingpins.

I have a permanet signal on PIN 6 ,14, 24 and 32.

First I thougt it is a problem of poor jackquality or my bad my solderingart.

Then I disconnect the flatcable and proof it direct on the PCB pins and the permanent signals are on the same pins, the rest is ok.

Any Idear?

Are you using default settings? Make sure you have AutoloadConf set to No.

[Nepo]

Autoload Config is no.

And I forget , the low pedal impedance is (PIN39/40) have a permanent signal too.

you can see it on one of the pics...

[dmitri]

Autoload Config is no.

And I forget , the low pedal impedance is (PIN39/40) have a permanent signal too.

It's not a signal, it's a position HiHat pedal is in according to current HiHat pedal settings. If settings are not correct or no pedal is connected it will show incorrect pedal position.

Can you make a video showing activity on the inputs 6, 14, 24 and 32 with no flat input cables connected to the board?

[Nepo]

Hello Dimitri ,

I'm not able to show you an vidio, only some pics.

Right Hand the proof needle, left hand the camera.
I show you only the pins 6 & 14 with permanent peaks, .... 24 & 32 and 2 from the small flatcable have the same roblem.

The the rest seems to be normal , peak only when I hit the piezo.

Is this VU-meter activity on those inputs without anything connected or indeed you connected something to those inputs as I can see on the pictures?
