Universal Audio OX Reactive Amp Attenuator Top Box

Universal Audio OX is a premium reactive load box and guitar recording system. It gives you perfectly studio-miked amp sounds from your favourite tube amp. OX lets you play and record your amp in its sweet spots. Get huge clean tones and edge-of-breakup to fully cranked sounds.

World’s Finest Guitar Amp Recording Solution

Get great sounds at any volume level, and with mic, room, and speaker cabinet emulations available. Featuring Universal Audio’s Dynamic Speaker Modeling, OX is the first system to accurately emulate speaker drive, breakup, and cone cry. This makes it the world’s finest speaker attenuator and guitar amp recording solution.

The World’s Best Reactive Load Box

With decades of analog hardware engineering expertise, UA’s dream team of engineers set out to design a reactive load box. One that retains the tone, dynamics, and feel of your tube amp — no matter how much it’s attenuated. The goal was for your tube amp to “see” OX as an actual speaker with continuously variable impedance and response — so you don’t lose a drop of tone or playing dynamics.

OX Complete Guitar Recording System

On OX’s front-panel is six-position RIG controls. They allow you to quickly choose from complete setups. Also, they include emulated speaker cabinets, close mics, ambient room mics, and up to four simultaneous studio effects.

In fact, OX is also the only guitar recording system to offer a complete selection of expertly placed room mics. Therefore, giving you the authentic experience of pushing air while recording your cranked amp in a world-class tracking room.

Dynamic Speaker Modeling

Additionally, UA’s groundbreaking Dynamic Speaker Modeling faithfully emulates speaker breakup, drive, and cone cry. This is an essential ingredient to authentic tube amp tones.

Also, using the Speaker Breakup knob in the OX app, you can control the harmonics and sonic complexity that occurs only at certain frequencies and volume levels on various speakers. This goes far beyond a static Impulse Response system. Therefore, giving you the same sonic phenomenon that occurs with a real speaker cabinet.

All The Right Connections

Not only does OX Amp Top Box feature a front-panel headphone jack for silent practice with your cranked tube amp, it also sports a bevy of connections for all kinds of recording and live workflows.

Stereo S/PDIF digital outputs via RCA and optical TOSLINK, as well as balanced TRS stereo line, outputs with front panel level control, give you the necessary connections for studio monitors, DAW, or live mixing console inputs. Plus, you can connect any one, two, or three-button footswitch and toggle OX’s studio-quality effects on and off.

OX’s Beautiful Software App

Lastly, 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 favourite tones onto OX’s front-panel RIG knob for instant recall in the studio or at a gig.
