Preamp circuit, inspired by our legendary UA 610 mic preamp. Plus, some Volt models feature
the analog 76 Compressor inspired by our iconic 1176 limiter heard on thousands of classic
records. Volt also includes MIDI for connection to a wide range of devices, and direct
monitoring capability for latency-free recording.
At UA, we're dedicated to the idea that technology should serve the creative process — not be
a barrier. These are the very ideals my father embodied as he invented audio equipment. We
believe Volt will earn its way into your creative workflow by providing stunning fidelity and rock-
solid reliability for years to come.
Please feel free to reach out to us via our website www.uaudio.com, and via our social media
channels. We look forward to hearing from you, and thank you once again for choosing
Universal Audio.
