The Cleanest, Most Natural Sound You've Ever Heard?

Sweetwater helps you excite your sound! There isn't a task in audio that can't benefit from the 482 Sonic Maximizer! A big claim, but it's true. In your studio, during performance or broadcast, for general sound reinforcement, the 482 works a special kind of audio magic.

BBE 482 Sonic Maximizer at a Glance:
  • Easy to read and use in dimly-lit environments
  • Reveals the sonic brilliance of your performance
  • Delivers a new level of realism to your instruments

Easy to read and use in dimly-lit environments
The Sonic Maximizer 482, which features a 1/4" thick extruded aluminum face plate anchored to chassis via hex head bolts, also benefits from improved graphics which are easier to read in poorly lit environments. In addition, new knurled, aluminum knobs have been incorporated for ease of control and a more positive feel, often critical to musicians, live sound mixers and DJs making fine adjustments mid-performance.

Reveals the sonic brilliance of your performance
The Sonic Maximizer can coax out the authentic sonic brilliance of a performance, giving you clean sound unhampered by the deviations that occur anytime music is played through a sound system. The highs in your sound are bright and articulate, the lows are tight and rich, the strings sparkle, the percussion cracks, the vocals shine.

Delivers a new level of realism to your instruments
Your instruments take on a whole new level of realism - the level they lost when they were first recorded or played through a sound system. And the final result is pure and musical. You hear the great performance; you don't hear the machine at work. Experience the magic of the 482 Sonic Maximizer!

Totally worth it

Ive used a stomp box version before so i knew how good these are. If you want chunk you get chunk, if you want clarity you got clarity. You need to get this and add it to your rig. You wont regret it. I run a stereo set up with a 100 watt Marshall plexi thru a two twelve cab with vintage 30s and a Marshall DSL 40. Wowza what an improvement. These are what I call the secret weapon to any rig. Get this.

Heaven sent

I difference in tone is amazing with this thing. I have on plugged into my Mesa Dual Rectifier and the difference with and without is day and night. Without the sound is tinny and weak with little bass. With it's like getting drop kicked at bedroom volumes.


In my opinion, every studio should have it! This thing gives life and clarity to your tracks, if you have a good ear you can use it in any recording situation. Especially on Bass, Guitars, Piano, Drums, acoustic intruments and vocals. Amazing for the price! I don't have a $1000 dollars preamps. And the BBE 482i with my $600 Preamp gave me a sound compared to these expensive preamps.

BBE 482i

The BBE 482i Sonic Maximizer offers two channels of BBE’s patented sound enhancement technology. It will brighten, clarify, and add depth and punch to your sound. It works by preventing the frequency robbing phase cancellation effect typical in traditional sound reinforcement technology by adding a delay of 2.5 milliseconds to the bass frequencies, 0.5 ms to the midrange, and also passing the high frequencies through a Voltage Control Amplifier (VCA), providing continuous dynamic amplitude corrections, ensuring proper high frequency content in the final audio signal and ensuring that the frequency content of the sound coming off your speakers hits your ear at the proper time, eliminating “muddiness” and “smearing”. The unit features a process control, offering up to 10db of phase compensated high frequency boost and a low contour knob offering up to 10db of phase compensated boost at the 50 hz frequency range. There is also an on/off switch, a bypass switch for comparing your effected sound to the bypassed sound, and an LED/clipping indicator. I use the 482 in the effects loop of my Vox AD-120 VTX. It works great to give solid state and digital modeling amplifiers a dynamic range on par with that of all-tube amps. With my VTX switched to the Modern High Gain, Recto, or US High Gain amp models, the BBE creates a huge, tight modern Metal sound. When used with the Plexi and Vox models, the BBE creates a bright, punchy classic crunch sound. When used with the Blackface 2X12 model, it creates a sparkly, present sound with a full and satisfying low end. Any of the available BBE Sonic Maximizer models are a highly recommended and cost effective method to improve your sound.

Magic Button

These things have been around for so long for a good reason. Put simply, they make good sound better. This won't clean your mix or fix your room EQ, and it can EASILY be overused, but it WILL enhance the thump and crisp that can be so easily lost in a live mix. This doesn't just throw some EQ in, it uses guru-math to manipulate the stereo and sonic fields to control the way sound approaches the ear from the speakers, and it's cool.
