Dielectric-Bias System (DBS, patent pending): When insulation is un-biased, its dielectric properties cause different amounts of time-delay for each frequency and each signal level.
Similar to how the earths magnetic field makes all compasses point north, the AQ DBS system creates an electrostatic field which causes the molecules of the insulation to all point the same direction. This minimizes the multiple nonlinear time-delays. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast.
The batteries in DBS packs will last for years. A test button and LED allow for the occasional battery check.
