Portable 4×4 USB Audio/MIDI Interface with Four Mic Preamps and Built-In Compressor
Four mic preamps with vibe-rich tube-emulation circuitry, built-in analog 1176-style compression, pristine pro-grade conversion, MIDI ports, and an impressive bundle of music production software make the Universal Audio Volt 476P portable 4×4 audio interface a top-notch yet affordable win for quality-conscious collaborators, vocalists, musicians, and even content creators such as podcasters and livestreamers. Attractive, sturdy, and compact, this USB Type-C interface is equally capable in a computer-based home studio or on the go with your iPad or iPhone.
Plug mics, guitars, or synths into the Volt 476P’s four mic / line / Hi-Z preamps and press the Vintage switches to impart the pleasing character of an emulated UA vintage 610 tube preamp to your voice or instrument. Keep peaks under control while adding punch with three selectable presets of 1176-like analog compression. Direct monitoring lets you hear yourself with no distracting latency, and there are separate volume controls for the speaker and the two headphone outputs.
Universal Audio bundled the Volt 476P with versatile and creativity-inspiring software including the popular Ableton Live Lite DAW, UJAM virtual instruments, Melodyne pitch correction, and high-end processors for mixing, mastering, and transforming ideas into polished productions.
Produce with Best-In-Class Sound
From the team that brought you the game-changing Apollo interface, Volt 476P delivers superior 24-bit / 192 kHz studio sound quality with character and tone far beyond its class.
Classic Vocal Tone
Few sounds can compare to a vintage Universal Audio 610 tube preamp, as used to record everyone from Ray Charles to Van Halen. Volt 476P gives you the rich, full sound of this classic UA mic/line/instrument preamp, thanks to its built-in tube emulation circuitry, a UA exclusive.
Control Volume Peaks with UA Compression
Get album-ready punch and presence with Volt 476P’s onboard 76 Compressor, an innovative analog circuit inspired by UA’s classic 1176 Limiting Amplifier. The 76 Compressor features three perfectly tailored presets to tame voice, guitars, synths, and drum machines. Just plug in, pick a setting, and play.
Easy In, Easy Out
Volt 476P gives you simple 4-in / 4-out audio connections. Just plug mics, guitars, or synths into the four XLR-1/4″ combo jacks on the front panel—48V phantom power is available for condenser microphones.
Connect your beat machine or keyboard controller to the MIDI 5-pin ports on the rear panel to easily integrate them with your setup. Then plug your speakers or headphones via 1/4″ sockets to monitor your audio with no latency.
Versatile Monitoring
With two 1/4″ monitor outputs and four 1/4″ line outs, the Volt 476P can feed speakers as well as outboard gear. Build a custom monitor mix by choosing any of the input/output pairs on the top panel, and toggle between monitoring in mono or stereo at the push of a button. There are separate volume-control knobs for the two headphones and the monitor outputs
iPad and iPhone Ready
Traveling light? Plug Volt 476P into your iPad or iPhone, and you can easily create beats and samples, record your band’s rehearsals, and edit songs anywhere. The external Volt power supply (included) and an Apple Lightning to USB Camera Adapter are required (available separately) for use with iOS mobile devices.
