I have just bought a Selmer PA 100, not actually picked it up yet, but it has an Ohm Selector, and you can chose between [color=#282828][font=helvetica, arial, sans-serif]3.75 (4), 7.5 (8) and 15 (16) Ohm speakers. There is also a 100V option, but I don't know what that means.[/font][/color] I have a Peavey 410TX which is 8Ohm, does anyone know if the selector enables the amp to run at 100W with any selection? i.e, if I wire it through my cab, will it be running at 100W?
I understand that most amps halve the wattage if they are 8Ohm but are being played through a 4Ohm cab, but does the Ohm selector change this?
