This BBE- DI-100 Sonic Maximizer is in excellect cosmetic and working condition. Comes with original power supply only.
The BBE Process-- ‘How It Works’
The BBE Process imparts a pre-determined phase correction to the high frequencies where most harmonic information exists. This is done by breaking the signal into three sub-bands or groups: a.) LOs (20Hz - 150Hz), b.) MIDs (150Hz - 1200Hz), and c.) HIGHs (1200Hz - 20kHz).
The low group is delayed about 2.5 ms (milliseconds) via a delay within the passive low pass filter. The front panel Lo CONTOUR control allows for either a flat response or a boost at 50Hz. The mid-range group is delayed only about 0.5ms and passes through an active band-pass filter while the high frequency group is passed through a VCA (Voltage Controlled Amplifier). The high group is used as a point of reference to make dynamic amplitude corrections to the high frequencies.
The RMS average loudness detectors continuously monitor both the mid-range and high frequencies to compare the relative harmonic content levels of the two bands and apply the appropriate amount of control voltage to the VCA, thereby determining the amount of high frequency harmonic content present at the final output of the BBE processor.
