AudioControl – How To Setup AccuBass Feature

Setting up AccuBass is quite a simple task, but can be scary for some the first time.

Before we get into setting it up, let’s look at what AccuBass is
Many factory audio systems reduce bass output as the volume is turned up to protect the $3 factory speakers. This factory bass ‘roll off’ can prove frustrating when adding aftermarket audio equipment to your car.

AudioControl’s patent pending AccuBASS circuit is designed to recover the bass that goes missing when the volume is increased in some factory sound systems.
AccuBASS restores bass around 50 Hz to 125 Hz; AccuBASS will not add content which is not already present in the signal and can be set to activate only when the bass in the factory system begins rolling off (using the Threshold knob). The end result is a smooth bass response at all system volumes.

Think of AccuBASS as the Barry White of bass restoration.

Alternatively, AccuBASS may be switched to “always on” (again using the Threshold knob – turned fully clockwise) to give rich enhancement to the low end of your music, for systems that do not exhibit a bass roll-off.

Lets Setup AccuBass!

  • The AccuBASS level knob determines the overall level of bass restoration.
  • The AccuBASS threshold determines when the AccuBASS process turns on.

For most of our products, the AccuBASS level and threshold knob are right next to each other.

The LC2i threshold knob is in a different spot. It is located on the side of the unit between the Main and Bass output. You will also need a screwdriver in order to adjust it.

It’s also good to note, the “Bass” knob on the LC2i is for the output gain. It does not have anything to do with the Accubass process. You use the “Bass” knob to set the level of the Bass RCA output.

  1. First, you will want to turn the AccuBASS
    threshold all the way down by turning the threshold knob all the way to the left (counter-clockwise)
  2. Set the AccuBASS level knob at the 12 O’clock position
  3. Start playing some music that you are familiar with that has a lot of bass
  4. Slowly turn the volume up on the head unit until you start to hear the bass start to drop out
  5. At this point, you will now start to slowly turn the AccuBASS threshold to the right(clockwise) until you hear the bass pop back in.
  6. At this point the threshold is set, you can now adjust the AccuBASS  level knob to your liking. You can think of the AccuBASS level knob as a bass boost at this point.

Now, in the scenario that your vehicle does not reduce the bass output at higher volumes, there is a way to have the AccuBASS process always on and then you can then adjust the AccuBASS level knob to your liking.

All you need to do is turn the threshold all the way to the right, which will bring threshold all the way down, effectively keeping the AccuBASS process always on. So then, no matter how loud or soft you are playing music, AccuBASS will always be engaged adding the bass boost.
