Audio-Technica AT803b Lavalier Microphone

The Audio-Technica AT803b is a miniature omnidirectional condenser microphone designed for clip-on lavalier and instrument applications. It delivers clear, unobtrusive sound pickup suitable for lecturers, stage performers, and television use. The system operates on either battery or phantom power for flexible installation. Its compact form factor ensures it remains discreet during presentations or performances.

Suitable For Speech And Instrument Pickup

This microphone suits users needing a small, omnidirectional element for voice reinforcement or acoustic instrument amplification. The integral high-pass filter helps reduce low-frequency noise from handling or ventilation systems. It is not suited for applications requiring a directional pickup pattern to isolate a source in high ambient noise. Buyers needing a handheld transmitter or a headworn form factor should consider different configurations.

80 Hz High-Pass Filter Switch

The defining specification is the selectable 80 Hz high-pass filter built into the microphone body. This feature allows the user to toggle between a flat frequency response and a low-end roll-off to compensate for proximity effect or rumble. Correct use of this switch determines whether the microphone captures full-range warmth or rejects unwanted low frequencies for cleaner speech intelligibility.

Questions about this item

How does the 80 Hz high-pass filter change the sound when the AT803b is clipped on a speaker?

The filter rolls off low frequencies below 80 Hz, reducing rumble and handling noise while keeping voice and instrument tones clear.

What connector standard does the AT803b use to plug into a wireless transmitter?

The microphone terminates in a standard 4-pin connector that mates with Audio-Technica body-pack transmitters.

What does the AT803b need for mounting on clothing or an instrument?

A supplied tie-clip secures the capsule to fabric, and the lightweight body adds minimal bulk for comfortable wear.
