Capture Legendary Tones with Vintage Mic Preamp Mode
Few sounds can compare to a vintage Universal Audio 610 tube preamp, the same preamp used to record everyone from Ray Charles to Van Halen. Volt 4 gives you the rich, full sound of this iconic UA preamp, thanks to its built‑in tube emulation circuitry, a UA exclusive.
Easy In, Easy Out
Volt 4 gives you simple audio connections to quickly get started. Just plug your mics and guitars into the front panel preamps, and use the line inputs for synths and drum machines. Then connect your speakers or headphones to monitor your audio with no latency. With Volt, you’ll be creating like a pro, fast.
