Universal Audio OX Reactive Amp Attenuator with Speaker Modeling

Universal Audio has always been a leader in high-quality analog hardware for recording, but over the last couple years, they have been making great strides in digital technology and integration of software and hardware. The new Universal Audio OX is the perfect combination of analog and digital, and is a must-have for every guitar player, studio owner, and live music venue.

OX is a premium reactive load box, which allows you to crank your tube amp up to its ideal sweet spot but keep it at a reasonable playback level. Integrated with state of the art software, and Universal Audio’s breakthrough dynamic speaker modeling, you are able to model a variety of classic speaker cabinets, classic dynamic, ribbon and condenser microphones, reverbs and delays, room tones, EQ, and compression. It’s the world’s finest boutique speaker attenuator and guitar amp recording solution.

Get the ultimate tone out of your tube amp - anywhere, and at any volume. You can pair your amp to the world's best reactive load, with boutique UA analog quality built for years of home and studio use. Instantly audition dozens of the album-quality mic and guitar cabinet setups with front panel "Rig" control. Get authentic "edge of destruction" tones complete with speaker breakup and cone cry, thanks to UA Dynamic Speaker Modeling

A Beautiful Software App

Most guitar products do digital awkwardly. They’re ugly and hard to understand. The OX software app, on the other hand, offers slick, intuitive control over all of OX’s RIG settings via Wi-Fi — letting you tweak, store and recall hundreds of presets from your iPad, Mac, or Windows 10 computer. You can then save your six favorite tones onto OX’s front-panel RIG knob for instant recall in the studio or at a gig.

OX Firmware v1.2

Free firmware update from UA includes:

• Five new speaker cabinet models
• External footswitch control of OX’s built-in effects
• 25+ new Rigs based on tones from legendary artists and albums

Solid State Amplifiers

OX can be used with solid state amplifiers (amps without vacuum tubes). However, when connecting OX to solid state amps, extra caution is advised so as not to exceed OX’s maximum input power rating of 150 Watts RMS or less.

An amp’s output power rating is sometimes labeled near the amp’s speaker output jack, or contact the amp manufacturer for the power output specification.

Caution: Many solid state amps exceed 150W output power and those that do can permanently damage OX. Damage that occurs from exceeding OX’s 150W input power rating is not covered under warranty.
