Amp settings

I have this old amp (Aiwa AX-7400) and i'm kind of wondering what one of the settings mean

There are two switches somehow connected to the bass and treble knobs. The first one, for the bass, has three possible values: 400 Hz, DEFEAT, 200 Hz
The treble one is labeled 2,5 kHz, DEFEAT, 5 kHz

What exactly do these two switches do?
