I am working on a school that we have added a class connect in a new building
We have single speakers in class rooms which work fine

And there are (3) locations that have 3 to 4 speakers on them

So we had to install a V-6120 and VMT1

They were complaining about the sound quality

I noticed the the output from the V-612 (10) watt

Were wired to the the negative & the shield as opposed to the positive & Negative

The paging was working fine prior to today when I noticed the wiring didn’t look right

I did call Valcom and ask them about it

They agreed it should be on the positive and negative terminals



So I move them to the positive & Negative

And then the V-6120 started to smoke

I’m assuming it didn’t like something I don’t know if it’s a short
I did call ValCom they one of the output was damaged but then after a while it might be damaged more outputs

It’ was working fine before I moved the wires

I thought it might be coming from one particular location

I am so confused

Any thoughts
