## Description

From the manufacturer SU9920 Ultimate Stereo Sound Enhancement Processor Dramatically improves your sound by adding clarity, dimension and depth Produces natural brightness through harmonic enhancement and tighter bass with increased punch through phase compensation Professional and home recording studios: brings out the full sound spectrum of your tracks, mixdown and mastering Dedicated Low contour and Process controls per channel for ultimate sound enhancement Accurate 5-segment LED level meters for optimum performance SONIC ULTRAMIZER SU9920 The SU9920 is a professional signal processor that can improve the presence and liveliness of audio signals of all types, giving your music the added dimension that will make your performances and recordings come alive! The SU9920 does this through the use of a special dynamic filter and a 3-band phase delay algorithm to add clarity, depth and punch – without any unnatural side effects. Since the SU9920 has 2 independent channels, you can process a stereo signal or 2 mono signals, such as a bass guitar in one channel – and a keyboard, vocal or guitar in the other. The ultimate sound enhancement tool for home and professional recording studios, DJ systems, PA systems and web-casting, the SONIC ULTRAMIZER SU9920 is also an amazing addition to your 5.1 surround and hi-fi setups. Why You Need the SU9920 Music is made up of very complex sound waves that cover a wide range of frequencies and harmonics. And no matter how good your sound system is reproducing music, in all its intricate detail, is an art that often requires a little something extra – something we call “magic”. The SU9920 provides a healthy dose of sonic magic using 2 simple controls (Process and Low Contour) to compensate for the phase and amplitude differences that occur between these frequencies during amplification – anomalies that can take the luster off an otherwise perfect performance. The SU9920 lets you always dial in the perfect sound, both in the studio – and in front of a live audience. Surprisingly affordable and easy to use, the SU9920 brings your music alive with articulate mids, sparkling highs and ultra-tight low end! Sweet in the Studio In a studio environment, the SU9920 brings increased focus and clarity to your sessions, and is the ideal choice for mastering all of your recording projects. Even if you work primarily with a digital audio workstation, you can easily add a touch of professional high-end polish to your music by using the remarkable SU9920 during the final mastering process. Vibrant Live Sound Using the SU9920 in live sound applications is the perfect way to give your sound system stunning clarity and incredible low-end punch – and with only 2 controls per channel, you’ll master dialing it up in no time at all! The Process knob controls how much of the high-frequency content is processed, with a maximum level boost of +12 dBu at 5 kHz. Likewise, the Low Contour knob controls how much of the low-frequency content is processed, with a maximum level boost of +12 dBu at 50 Hz. With these 2 simple dials, you can make major signal quality improvements and bring out the very best in your sound system – whether you’re mixing a duo at the coffee house, or dialing a massive outdoor concert! Maximum Intelligibility In public facility applications, such as churches, meeting halls, and other predominantly spoken-word venues, the SU9920 dramatically increases vocal intelligibility, so the speaker’s message is clearly heard – all the way to the back of the room. Musical performance in these applications also benefit from SU9920 enhancement, exhibiting increased punch, definition and high-end presence – even at surprisingly low volume levels. Versatility In addition to being great for use with stereo signals, the SONIC ULTRAMIZER is ideal for individual instrument signals, such as guitar, keyboards or bass. Just connect the SU9920 into the signal path, or use your amp’s effects loop, for sound with more presence, fullness and punch. Since the SU9920 can be run in stereo or dual mono, you can even use one side for the bass, the other for a keyboard or guitar. Sound Value You’d be hard-pressed to find any other single piece of gear that can improve the sound of your recordings or live shows more than the SONIC ULTRAMIZER SU9920. And this mastering marvel is so very affordable, you’ll want 2 or 3 for your studio, and a couple more for your live rack. Get down to your Behringer dealer, or get your first SU9920 online today – you will be back for more!

Review: Highly recommend this product for anyone wanting to get the most out of their speakers. - I bought this , not only because it’s cheap but to see if it really does change the sound that much , and after some testing I’m genuinely very impressed with this piece of equipment. The speakers I’m using are a pair of Behringer Eurolive VP2520 which do sound quite good but definitely lack the crisp highs you’d expect from higher end speakers which is expected considering the price of these speakers , after installing this sonic ultramizer and testing at different levels using the process and low contour knobs to find the sweet spot , it makes quite a significant difference , I can tell the difference by simply pressing the in/out button on the front of the unit which bypasses it so that’s a nice little thing to have for testing! Honestly , the only way I can describe the sound is , it sounds more full and has more presence , the bass doesn’t sound boomy it gives it more punch and brings out more highs in songs and just sounds nicer overall. I can highly recommend this to anyone wanting to get more out of their speakers whether they are big or small I believe you will notice a difference and for £55 , it’s definitely worth it. You might not be able to tell any audible difference with the video I provided , after watching the video the difference is subtle but in person it’s a way bigger difference
Review: A bargain and fantastic sound enhancer - A simple way to describe the sound enhancement from this little gem is it enhances the projection of detail within a mix. And really it works well. The two controls for each channel are simple. I have found that the bounce enhancement is the most useful. This does not make the mix deeper but acts to enhance mid bass tones so it feels that you hear it clearer. It does not enhance stereo spread. Its use for me is in a studio where it takes the final mix and sorts out clarity. So that mastering is not really needed. The straight recording is good when it comes out this rack unit. Note all io is TRS balanced or XLR. No TS available. The unit introduces no noise. the effect bypass button does bump a bit but nothing that could blow speakers. I found that there are no balance issues with pot positions n stereo use. This a very low cost rack unit that gives really good results in sound quality.

## Questions & Answers

**Q: Does this replace the need for graphic equalizer? Anyone using both?**
A: Hi their Yes i use both i have got a 30 cannel graphic in my tower and i also use a 15 cannel with the ultramizer in conjuunction together
for a clearer sound the sonic do's help but to get a nice pumping sound with the bass then yes it will do what you need the process high end
makes it a bit tinny but when you push the in and out button it pulls it together.
hope this will help you with it. but yes you can use them both together

**Q: Can i use behringer su9920 sonic Ultramizer sound Enhancement processor with a crossover?**
A: I didn’t get on with the crossover . Didn’t suit my speaker set up. Also, double check the wiring sockets. Not good for home use.

**Q: Will all the wire connections come with the processor for my amplifier, or do I have them?**
A: No, You will need 4 mono cables (balanced is better) or mono to rca connectors

**Q: Does this have agc (automatic gain control) or something similar to “level” the volumes from different tracks?**
A: no it does not have any input gain. as this comes from a mixer out or effect send the sound is levelled before reaching the unit hope this helps

Great value for the money! My music system now sounds much better - would recommend, and this comes from a music gear snob who always thought that Behringer is pile of junk - ohh what a mistake, my apologies to people from Behringer
