    About this Product

    The Audio-Technica AT831B is a cardioid condenser lavalier microphone delivering crisp, full-bodied voice pickup. Equally effective as an instrument microphone — particularly for acoustic guitar via the included AT8444 adapter — it offers excellent gain before feedback and operates on phantom power (11-52V DC) or a single AA battery.
