Congratulations on your purchase of the BBE BMAX Bass Guitar Pre-amp!
The BBE BMAX is an extremely versatile pre-amp which is capable of achieving a wide array of tones while conveniently configuring itself into any application. No extra devices are needed to get flawless performance out of the BBE BMAX.
The BMAX is a high quality bass preamp/processor with applications both in the recording studio and on the road in demanding live applications. The BMAX has the warmth and dynamic range usually found in all-tube designs and will deliver the punch and clarity of the best all-tube preamplifiers. The fit and finish is solid with a professional feel that will appeal to professional Bassists and semi-pro players alike.
It features a class A/B front-end, the input of which emulates the loading effect that the input of a “classic-design” tube preamp would present to the bass pickups, this is one of the key aspects in the “warmth” and “punch” of all-tube preamp designs.
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. Research shows that the information which the listener translates into the recognizable characteristics of a live performance are intimately tied into complex time and amplitude relationships between the fundamental and harmonic components of a given musical note or sound. These relation­ships define a sound's “sound”.
When these complex relationships pass through a speaker, the proper order is lost. The higher frequen­cies are delayed. A lower frequency may reach the listener's ear first or perhaps simultaneously with that of a higher frequency. In some cases, the fundamental components may be so time-shifted that they reach the listener's ear ahead of some or all of the harmonic components.
This change in the phase and amplitude relationship on the harmonic and fundamental frequencies is technically called “envelope distortion.” The listener perceives this loss of sound integrity in the repro­duced sound as "muddy" and “smeared.” In the extreme, it can become difficult to tell the difference between musical instruments, for example, an oboe and a clarinet.
BBE Sound, Inc. conducted extensive studies of numerous speaker systems over a ten year period. With this knowledge, it became possible to identify the characteristics of an ideal speaker and to distill the cor­rections necessar While there are differences among various speaker designs in the magnitude of their correction, the overall pattern of correction needed is remarkably consistent.
