The OX Amp Top Box solves this with a premium reactive load box that absorbs the amp's full output, letting you play at sweet-spot volume internally while attenuating the audible output to anywhere from \"completely silent\" to \"full band volume.\" Combined with UA's Dynamic Speaker Modeling (the same technology in OX Stomp), you get studio-miked tones — speaker, microphone, room — direct to your interface, headphones, or PA.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium Reactive Load Box\u003c\/strong\u003e — Your tube amp sees OX as an actual speaker cabinet with continuously variable impedance, preserving tone and feel regardless of attenuation level.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFive Attenuation Levels\u003c\/strong\u003e — Completely silent, whisper-quiet, bedroom, club, full band volume.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUA Dynamic Speaker Modeling\u003c\/strong\u003e — Emulates speaker drive, breakup, and cone cry; far beyond static IR loading.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront-Panel Six-Position \"Rig\" Control\u003c\/strong\u003e — Instant recall of six complete cab + mic + room + effects setups.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt-In Studio Effects\u003c\/strong\u003e — UA EQ, compression, delay, and reverb.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeadphone Output\u003c\/strong\u003e — Silent practice with cranked-amp tone.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced Stereo TRS Line Outputs\u003c\/strong\u003e — Direct to interface or PA.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eS\/PDIF Digital Output\u003c\/strong\u003e — RCA and ADAT (TOSLINK), 16-bit \/ 44.1 kHz.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelectable Impedance\u003c\/strong\u003e — 4-, 8-, or 16-ohm operation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWi-Fi Control\u003c\/strong\u003e — Pair with the OX mobile or desktop app for deep editing and preset management.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Amp Support up to 150W RMS\u003c\/strong\u003e — Handles most popular tube amp heads and combos.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow OX Differs from OX Stomp\u003c\/h2\u003e\n\u003cp\u003eOX Amp Top Box is the original UA product — a reactive load box and speaker emulator designed to take the speaker output from a tube amp and convert it to line level, with cab\/mic emulation.
