Beolab 4000, W and T settings

2 replies

Hi all,

I was cleaning my Beolab 4000 earlier when I noticed two very small of what would appear to be switches that are adjustable using Phillips head screwdrivers (I haven't touched them) They appear to have a W and a T beside them, but does anybody know what they're for?

They are used in the factory when testing to set the output levels of the woofer and tweeter to compensate for driver differences so the speakers response is to spec, and to do the same thing if a driver needs changed in service later. Say if you blew a woofer and they had to change it. Not to be messed with!
