With the patented BBE Process, music has a great "live presence". Unlike some "exciter" devices which add artificial harmonics to the signal, BBE adds nothing artificial but instead restructures it to faithfully allow all the detail and nuance to be heard. Highs frequencies are clear, naturally brilliant and finely detailed. Lows are tight, well defined and harmonically rich. Electric and acoustic guitars have sparkle, clarity and definition. BBE brings out the harmonic complexity so each note of a chord becomes more distinct. Electric & acoustic basses take on a rich, earthy "CD" sound. BBE yields extremely tight, punchy bottom end without sacrificing the presence, clarity and bite on the top end. Keyboards and synthesizers take on new realism. Percussive and plucked sounds are clear and sharp; chords are rich and full-textured with each note in the chord retaining its integrity. Vocals cut through the amplified instruments so you’re no longer "buried in the mix". Sound contractors know that vocal intelligibility is paramount to a successful PA installation and client satisfaction. No other audio processor brings natural clarity and crisp definition to the spoken word like BBE does. That's why BBE Sonic Maximizer processors can be found installed in PA systems ranging from the massive network in New York's JFK airport to the thousands of houses of worship around the world. Recording studios use BBE on individual tracks, mixdown, and of course in mastering. Mixes with BBE are fresh and sparkly, restoring instrument clarity and vocal intelligibility without appreciably adding level. BBE improves effect processing by expanding the spatial dimension of stereo reverb and chorus. Whether in an individual instrument rack or across a full mix, BBE makes a dramatic improvement in the quality of effects and neutralizes their tendency to muffle instrument and vocal characteristics.
