Universal Audio Apollo x8p Heritage Edition Rack Mount Audio Interface

Silence the Volume, Not the Sound

The Universal Audio OX Amp Top Box is a premium reactive load box designed specifically for guitarists with tube amps. It lets you crank your amp for that sweet, spot-on tone without blowing out your eardrums or those of your neighbors. Decades of analog hardware expertise went into crafting the OX to act as an invisible extension of your amp, faithfully preserving its tone, dynamics, and feel at any volume level.

Effortless Recording Perfection

Simply connect your tube amp's speaker output to the OX, and then connect the OX's output to your speaker cabinet. With the six-position RIG knob, you can instantly select from a vast library of iconic speaker cabinets, studio mics, and room tones – all meticulously modeled to capture the sound of legendary amps cranked in world-class recording studios.

Unleash the Magic of Speaker Dynamics

Universal Audio's groundbreaking Dynamic Speaker Modeling goes beyond static Impulse Responses. It emulates the nuanced breakup, drive, and subtle nuances that occur when you push a real speaker cabinet. The OX app lets you fine-tune these details for hyper-realistic, organic tube amp tones.

Intuitive Control at Your Fingertips

Forget clunky interfaces! The OX software app provides a slick, user-friendly way to control all of the OX's settings via Wi-Fi from your iPad, Mac, or Windows 10 computer. Craft and store hundreds of presets, then call up your six favorites directly from the RIG knob for instant access in the studio or onstage.
