Behringer SU9920 Sonic Ultramizer

A beautification processor designed to enhance your sources and mix

The BEHRINGER SONIC ULTRAMIZER SU9920 belongs to the family of sound enhancement processors designed to provide that "extra" which is difficult to achieve with traditional equalization alone. Its approach combines brightness enhancement through harmonization and increased bass perception via phase work. The result: a more open, lively mix sensation, with a low end that gains solidity without having to start over with your settings.

In a modern setup (home production, online streaming, DJ sets, hi-fi listening), the SU9920 serves as a practical tool when you want to quickly add an extra dimension to a stereo signal, whether on a bus, a source, or a playback chain.

Who is the SU9920 for and what are its uses?

The SU9920 is aimed at anyone seeking an audible improvement without complexity. In the home studio, it can help reveal details in a dull mix, restore air to a dense production, or provide a more immediate sense of clarity during listening. For DJs, it is a simple solution to enhance the perceived punch and brightness on a sound system, especially when the musical program varies greatly from track to track.

Keyboardists and rack musicians will also find an ally to highlight the attack and presence of synth sounds, electric pianos, or stems, while content creators and webcasting professionals will appreciate the added definition that can make a broadcast sound more "pro" and intelligible. Finally, on the hi-fi side, the device targets those who enjoy optimizing the sense of breadth and depth, both in stereo and 5.1 surround installations.

Sound processing: harmonic brightness and enhanced bass

The SU9920 acts as a stereo exciter/enhancer: it enhances the signal clarity by emphasizing natural brightness through harmonic processing. Unlike a simple treble boost, the idea is to add perceived presence and definition while maintaining pleasant musicality, especially on sources lacking depth.

Bass: more impact thanks to phase compensation

The low-frequency section of the SU9920 does not just "inflate" the bass: it relies on phase compensation to accentuate the sensation of power and depth. This is particularly useful when a mix sounds thin or when the low end lacks authority on certain playback systems. The goal remains to achieve bass that is more present but also clearer, with a more convincing foundation.

Dedicated controls for immediate results

To get straight to the point, the low-frequency processing section features dedicated Low Contour and Process controls. This "quick adjustment" philosophy is ideal in real-world situations: you adjust the intensity of the enhancement without going through a complex chain of plugins, and you tailor the sound to the musical style, listening system, and desired level of intervention.

Whether you seek subtle optimization (just the right amount of openness and firmness) or a more pronounced effect for a more spectacular result, the SU9920 encourages exploration: it invites you to test, compare, and find that balance point where the music gains dimension while remaining natural.
