The DD Audio BSI (Bass Signal Interface) is designed for audio systems that need a little extra control over the lower frequencies to realize the full potential of a powerful sub stage. With this one piece of equipment you can restore bass that was lost from music during the recording process, enhance bass content that is already present in the recording, and then boost the bass to a level that suits your bassaholic needs. The BSI’s control arsenal employs variable parametric bass processing, 24dB/Oct subsonic and low pass filters, and digital frequency anylisis. These features let you manipulate every aspect of the bass signal so you can add impact to your music with the precision of an audio surgeon. Once the BSI’s acoustic controls are dialed in the multifunction remote control allows for on the fly adjustability of the master volume, effect on/off, and effect level. To make it easy to integrate into almost any aftermarket or factory audio system the BSI is equipped with differential balanced RCA inputs, high level inputs, selectable input voltage range, and auto turn on features.

Active signal processors capture the audio signal before it gets to the amplifier allowing you to modify the waveform to meet your needs. They require external power to operate, but provide a higher degree of adjustability than most amplifier preamps or passive (non powered) devices.
