Qsc mx 1500 120v

[sakis]

ok now .....costumer has 4pcs of QSC MX 1500 but those are rated 120v each

option one replace a couple of trafos on each amp and you are done

but since 2 trafos exist in every amplifier i could try to wire them in series is this though going to create the trouble that if one of the two channels is loaded then the line voltage on the loaded chanel will decrease while in the other chanel will increase or not ???

advice please

Are the two trafos supplying each channel respectively?
Or are they one for the positive, and one for the negative supply?

...anyway - you are right! It could definitelty cause some troubles no matter what.

The amps have separate supplies for each channel. No, you can't wire the primaries in series. The only time you can do that is if both trafos are always subject to exactly the same load.
