Audio Mixers

Not Sure if I got it right but (Admins move the post if it's not in the right topic)

Guys, I'm a slight predicament. My mother can hear the Bass on my 5.1 Logitech Speakers in the next room which I thought it may sound really good untill she complains, I also bought lasers to pick up the sounds. I'm looking for good Cheap Audio mixers range budget $60 to $150. I need to find something that can bring the Bass down more. My YPG 235 has a Bass that is way louder than other Instrument in the Styles and it doesn't have Audio Adjustment. Now I'm not complaining the Keyboard is no good. I love it! Got some great sounds. But my problem is I need a Better Audio Mixers. Even some of you go out Gigging and you information will really help alot. I can use the headphones but I have hearing issues since my Ear Surgeries I cannot prolong for headphones.

I'm searching on Amazon to find the right Audio Mixer.

While a mixer may do what you need, perhaps a better way to roll off the low end would be use of an equalizer which may allow more precise adjustment of the frequencies. These two from Amazon allow adjustment of individual bands of frequencies, rather than the 'shelving' type of control most mixers usually have. The more 'bands' the equalizer has, the more precise the control.

If you do have a use/need for a mixer, I would likely recommend the one below which in addition to high and low shelving EQ, it has a 5 band graphic equalizer and effects.
