Simple Ncore Wiring Question

Is this correct wiring? I still cant find a simple description of EXACTLY what to do, after a year of on and off effort....

Looks like 1) blue wire===========to XLR pin #2
2) white wire==========to XLR pin #3
3) nAMPON (black wire)===to switch if you want standby mode
4) shield wire==========to chassis XLR bolt

also included picture hope it helps. ZAK

Is it possible to wire nampon, sheild together (if not using a switch), send them into pin1 and pin1 to chassis? Thus only having one chassis connector?

what switch did you use for the nampon?
thanks,

Just a simple on/off toggle switch. ZAK

does the nampon wire go to on and the off to ground?
thanks,
drmike

Basically, in the off position (standby mode) the wire from amp does NOT (with a continuity tester) go to ground.
in the on position (play mode) the wire from amp does GO (with a continuity tester) to ground. Hope that Helps ZAK

just trying to figure out the picture of the nampon standby switch shown in the post. does the longer black wire come from input wire bunch and the shorter wire goes to the chasis?
thanks,
drmike

HEARS A COUPLE MORE PICTURES. ZAK

This is the one. mini toggle switch # M101 . ZAK

Can anyone tell me if its necessary to use any solder when connecting to Chassis? I am finishing my build today and want to confirm this is right:

Pin 1 - Chassis

Shield - Chassis

Nampon - Chassis

I will actually have 4 seperate chassis connections in total as I am earthing the IEC also.

Thanks

Use an eyelet that is crimped or soldered to the wire and the eyelet is then fastened to the chassis. DO NOT attempt to solder the wire directly to the chassis.

THats what I have. I bought some from Ghent Audio as it was easier. Just wanted to check whether you needed to add solder to the eyelet. Obviously not

So is it ok to do all four chassis connections seperately?

The way you asked the question lead me to think that you were going to try to sodler the wire directly to the chassis. If you want to crimp and then add some solder you can do that if that gives you the warm fuzzy feeling. If you use a proper crimp tool you do not need to do that. I obviously have no idea what tools you have nor the knowledge.

It's nice to have them go to one common spot. However, I did separate the IEC ground and XLR ground so I could keep everything as short as possible. That's just me though and there were no issues.

Ill be using these.

On reflection, because I have just the wire of Nampon and the sheild will also be bare wire (in other words not the simple job of just soldering one of the above to the XLR input and onto the case, I now propose to solder together Nampon and Sheild and solder onto pin as per the attached diagram. Is that ok? That way I actually only have one chassis connector around the XLR input (and one for IEC). Is that ok?

I think you're overcomplicating this.

IEC ground to the chassis

Ground and shield to the XLR and that to the chassis.

Done.

zenpmd · « **Reply #18 on:** 14 May 2015, 06:18 am »

When you say ground I assume you mean Nampon?

What is the purpose of the little connector on the XLR which isnt one of the pins? I am planning to connect nampon and sheild to pin 1 only and then pin 1 onto chassis?

I will leave it for now. Soldering the XLR was easy enough, though I dont really fathom how to make it look neat with the sheild and everything, but I am really struggling with the speaker terminals. I cannot ge the solder to take onto it, all Im doing it making a massive mess and covering the wire in more and more solder. What do I do?
