Can anyone tell me what these do?

Question

I am trying to find out ecxatly what these control on my radio. Do they control bass, treble, etc. Or something else entirely?

60 Hz

150Hz

400Hz

1 kHz

2.4kHz

6kHz

15kHz

Answer 1

It's the graphic equalizer. The 60Hz number would be the extreme low bass sound an the 15 kHz the extreme high or treble sound. Just kind of mess with it until it sounds right to your ears.

Answer 2

60Hz is hooming or punchy hitting bass. under 40Hz it is deep....

Answer 3

It's an equalizer so you can customize how your stereo sounds.

Answer 4

i agree with above, move each one to the extreme high and extreme low, to see how each sounds
