A solution for silent guitar recording

The OX Amp Top Box from Universal Audio is an analogue silent recording box that can be used to authentically capture the tone and dynamics of any tube amplifier in outstanding quality. This setup allows the player to set their amp to its sweet spot - however high that might mean cranking the volume - and to enhance the sound further by adding Universal Audio's high-quality microphone, room, and speaker simulations while recording. The dedicated and easy-to-use software app can also be used to programme and control the Universal Audio OX Amp Top Box via WiFi.

The ideal load box

The OX Amp Top Box is a high-quality reactive load box in an amp head-style format that gives guitarists the freedom to play and record whenever they want and at any desired volume. What is more, UA's groundbreaking "Dynamic Speaker Modeling" technology means that the amplifier actually perceives the OX Amp Top Box as a speaker, and its tone, dynamics, and feel are thus captured with the same authenticity as if it were being played through a real speaker cab. The speaker breakup control found in the app adjusts the harmonics and sonic complexity that occur at specific frequencies and volume levels, and the OX's front panel features dedicated volume controls for headphones, speakers, and the line output.

For quiet players and recording specialists

All too often, getting the best tone out of a tube amplifier inevitably means having to crank the volume up to unbearable levels, and Universal Audio has designed the OX Amp Top Box to tackle this age-old problem and allow users to play, practise, and record with one hundred percent of their amp's tube tone at any time of the day or night.

Tube amp tone on tap 24/7

Universal Audio's OX Amp Top Box gives players the freedom to fully enjoy the sound of their tube amplifier at any volume level - whether they are trying out new riff ideas at 3 o'clock in the morning or practising and recording - without disturbing anyone. As mentioned above, recording is also possible even without the use of a speaker cabinet, and users additionally have Universal Audio's authentic-sounding mic, room, and speaker simulations at their disposal, providing even greater sonic flexibility.

About Universal Audio

Few manufacturers can draw upon a wealth of audio engineering experience comparable to that of Universal Audio. The company’s founding father Bill Putnam, along with his friend Les Paul, have an admirable reputation as trend-setting music producers and developers of legendary analogue studio technology. Putnam recorded Chuck Berry, Muddy Waters, and Sarah Vaughan, and was Duke Ellington’s favourite sound engineer. He developed the famous 1176 Peak Limiter and distributed the Teletronix LA-2A level amplifier. This earned him a posthumous “Technical Grammy Award” in 2000. In 1999, Putnam’s sons, Bill Putnam Jr. and James Putnam, re-founded Universal Audio, transferring their father’s analogue vision and craftsmanship to the digital music world. Their product range includes audio interfaces, dedicated DSP farms, and a variety of plug-ins, as well as analogue hardware devices.

The separately available software for Mac and iPad provides maximum access to all of the OX Amp Top Box's presets, parameters, and effects and gives the user a clear and comprehensive overview of all the relevant information, allowing them to select the right speaker, microphone, and EQ settings easily and intuitively.
