THE BBE PROCESS—"WHAT IT IS" Loudspeakers have difficulty working with the electronic signals supplied by an amplifier. These difficulties cause such major phase and amplitude distortion that the sound reproduced by speaker differs significantly from the sound produced by the original source. In the past, these problems proved unsolvable and were thus delegated to a position of secondary importance in audio system design. However, phase and amplitude integrity is essential to accurate sound reproduction.

The 1/4” input is designed for running instrument cables directly into the DI-400. Engages the Sonic Maximizer Process. When the switch is pushed in, the BBE Process is on. When the switch is up, the BBE Process is off. Regulates the amount of phase corrected bass frequencies. PROCESS CONTROL Regulates the amount of phase correction.
