Hi,

I bought the kit from Synthex. I have all the components soldered, and I have to wire the jacks. But I have two doubts.

1. Do I need to use the jumper? and what is it for?
2. I bought female jacks with open and close circuit. What are the advantages of using the open / close circuit with megadrum? and how should I wire the different connections to use this characteristic?

Thanks

The jumper is from power : USB or External power.
Do NOT use jumper "USB Power Switch" and "Alim Ext Jumper" at the same time.

With switched jack (open/close circuit) inputs can be connected to ground if there is no jack.

It depends on your jacks.

I'm connecting a switch to the USB power switch, so I can turn the module on and off. In this case, I don't need to use the jumper. If I wanted to use Alim Ext I should put the jumper in Alim Ext Jumper. Is it right?

It depends on your jacks.

The female jacks have six pins each. Tip - Ring - Sleeve and the corresponding pins for the switches. When the jack isn't used the circuit is closed, and it is open when a male jack is plugged. I have read in other thread that using this characteristic we can avoid parasites. But, is it worth using it? and how should I do all the wiring? connecting the pins to the ground?

Hi

another doubt. How should I connect pins 3 and 4 for the hihat controller? as the other jacks, ground, pin 4 and 5?

Yes. If you wanted to use Alim Ext you should put the switch in Alim Ext Jumper.

Yes, you have to connect the pins to the ground.
