Its a little knob in either the front or the back of the TV. Adjusting it makes the picture tube show brighter or darker.But seriously its usually a control to vary the high frequency response of a speaker. Exactly how much change it imparts and at what frequencies are speaker dependent and could be covered in the speakers owners manual.

I'm a novice so I'll try to make my question more pointed. Can any/all of these simply be bypassed. It sounds like it is in some sense a functional part of the crossover and so should be taken into account, requiring a redesign of the crossover. Having my signal pass through a 50cent switch that is 50 years old, seems like a bad thing. I have yet to crack these things open so I don't know the nature of the crossover, but its just a two way so the "crossover" might just be a resistor on the tweeter, and probably the brightness control is the crossover. Is this possible? Its the emi 62 which is rare but similar to the other emi co axials with oval woofer.
Less is more! By all means find the level you like and use fixed values and get rid of pots,switches,lpads and rheostats.
So you say you are a novice but that philosophy shows wisdom as I see it.

What is it a slide switch? If so it is most likely just a switch between resistor values. Yes you can just jump it out. I'm sure there is a crappy contact inside that switch anyway.
yup, slide switch. Had a hell of a time with my AR 4x's with the knob. The whole channel would drop in and out.

I'm pretty sure that switch is a pretty low audio quality device.
Sure, but got the impression that he didn't want soldering projects.
