The Planet Audio PA300 Digital Bass Processor is a specialized mobile audio component designed to restore and enhance the bass frequencies present in your music. It is like an acoustic magnifying lens. The flexible control system permits you to identify the bass frequency as a "center frequency" around which maximum enhancement will occur. This is similar to the central frequency selected in a parametric equalizer. The range of frequencies enhanced can be very narrow or relatively wide. By using the "Effect Range" control you can decide if you want a particular bass frequency to punch much harder than usual or a wider range of frequencies to be boosted.

Any device that increases the level of deep bass can increase the rumble and incur the risk of damaging your speaker system. That is why we decided to include a PWM Subsonic Filter in the PA300. Generally, setting this filter to 33Hz (which will eliminate frequencies below 33 Hz) will offer protection for most speaker systems. You may also want to experiment and set the subsonic filter to a higher frequency, as this sometimes has the effect of making the sound louder and cleaner.
