Can I adjust these controls?

[JSantiago]

Can I adjust the bass and treble adjustment buttons without harming the speakers or the unit? (see picture below) This unit is a STR-DH130. The range is from -15dB to +15db. If I had +12dB does that mean I have to have -12db treble? Also, could I have +15dB bass and +15dB treble at the same time? (or vice avers (-15dB bass and -15dB treble?) Thank you for the answers, I will try to respond if I have another question with comments or posting an answer on my question. Please respond to my replies, thank you!

Yes you can set them however you want and yes this can damage speakers

These are just volume controls but unlike the normal volume control they only change certain frequency ranges.

Do I want a sound bar with built-in amplification?
