I have recently bought a pair of Triton 2 plus in the US which uses the 120v version. I have also recently accepted a position in Switzerland which uses 220v. Will the 120v Tritons work on that power supply or will I have to change to the 220v version?

Congratulations on the new position and good luck on the move! Exciting and stressful times ahead.

The amplifiers in the Triton Two+ are not switchable to 220v. You can run them with a GOOD step down transformer, or replace the amps internally.

Historically we have not inventoried 220v. replacement amps in the US, but recently have begun to keep a few in the US for just this type of circumstance.

I'll send a PM with some additional information and we'll see if we can get them swapped out before the move.

Congratulations again.
