Audix USB12 — Cardioid Condenser USB Vocal Microphone
USB12 Overview
The Audix USB12 is a miniaturized USB condenser microphone built for recording vocals and acoustic instruments directly into a computer without the need for an external audio interface. Its uniformly controlled cardioid polar pattern delivers focused source isolation with a smooth, accurate response across a frequency range of 50 Hz to 16 kHz. The USB12 supports both 44.1k and 48k sample rates for flexible playback and recording workflows. It is well suited for voice-over artists, podcasters, remote broadcast contributors, and content creators who require a compact, self-contained recording solution.
The USB12 includes a bass roll-off filter to manage unwanted low-frequency content, and its push-to-talk button operates in both steady-on and momentary-on modes, providing practical control during live recording or communication sessions.
