2 independent Sonic Maximizers in 1 chassis!

The BBE 482i Sonic Maximizer is perfect for home studios, DJ systems, PA systems, nightclub sound, and guitar, bass, or keyboard racks-any application not requiring balanced jacks. It provides processing for stereo or 2 separate mono channels-brightening, clarifying, and adding fullness to the sound. Features 5-segment LED output meters, +18dBu headroom, RCA and 1/4" inputs and outputs, and a bypass switch for comparison of processed to unprocessed signal. Occupies one rackspace.

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 the speaker differs significantly from the sound produced by the original source.
In the past, these problems proved unsolvable and were thus relegated 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 necessary to return the fundamental and harmonic frequency structures to their correct order. While there are differences among various speaker designs in the magnitude of their correction, the overall pattern of correction needed is remarkably consistent.
The BBE Process is so unique that 42 patents have been awarded by the U.S. Patent Office.

Comments about BBE 482i Sonic Maximizer:

A must have for any rig. These are not equalizers. It analyzes your signal/tone and fixes it on the fly. It brightens, clarifies, and adds fullness to the sound. Do you have a tone in your head that you're trying to replicate? Put this in your signal chain and stop worrying about your tone, it's fixed. Guitar chords with distortion now ring though instead of "muddying-up."

I have always used Marshall combos, but some lack the punch/clarity of full/half stacks. This will correct that. Gives you the bass you can feel and full tone you've been lacking. Currently use it in all my setups, and just can't do without it. No manual needed to learn. Process IN/OUT button, low contour know, and high contour knob. Put both on 5 or 6 and you'll be amazed. Need more/less, just tweak it. Now hit the process IN/OUT (bypass switch) to see how much better your tone is. Also has RCA inputs/outputs for use in home theater systems.

This one has an (A) channel and a (B) channel, so you can share with you friend. You'll only need one unless you run a complex stereo setup, which most of us don't.

Note: I have tried the BBE stompbox versions of this and they fall short in the effects chain. Get this one and put it in your effects loop instead. Every stompbox that has a TONE knob or EQ compromises your tone. Stay away from those. Your guitar and amp already has TONE knobs for that, so keep it simple.
