Bass- The boomy deep sounds that you here. you can tell if you turn bass up your system will be much more "boomy" so to speak.

Treble- This is to increase or lower the vocals and higher frequency sounds. if you turn it up then down you should be able to tell what im trying to explain.

Fader- This is to adjust which speakers output more sound (front and back). so you can set it up so your rear speakers are the only ones playing or your fronts or even a 20% front 80% rear "fade".

Balance- This is the same as the "Fader" option but instead of front to back it is side to side.

SVC- This one is kinda tricky. Let me first explain this... As you drive, the higher your speed, the more "road noise" your car will make. This setting usually has an off, low, med, high setting.. Now, what it does is it automatically adjusts the volume of your music in relation to how fast your car is going in order to compensate for the higher noise levels your car will be making at higher speeds... I find this setting annoying and have it set to "off" but everyone has their own preferences.

Hope this was clear enough and helpful :)

Bass: Adjusts the lower tones being played. IF you turn the Bass up, the low tones will be louder.

Treble: Adjusts the higher tones being played.

Fader: Adjusts the balance between the rear speakers and front speakers.

Balance: Adjusts the balance between the right side speakers and left side speakers.

SVC: Speed volume control. When you drive a car fast, the road noise is noisier than when you drive slowly. SVC can be adjusted to automatically make the radio louder when you drive fast.
