What is the WL93 best suited to?

The WL93 omnidirectional miniature lavalier condenser microphone is designed for use in speech applications such as broadcast presenting, speeches, lectures and for use in houses of worship.

 

What are the characteristics of the WL93?

Despite its small size, the microphone element provides full, clear sound comparable to that of much larger microphones. Its frequency response is tailored to body-worn applications, with low-end rolloff and presence rise.

 

What accessories does it include?

The WL93 is supplied with a sew-on mounting bracket, a mounting block with attached tie bar, and an acoustic windscreen to minimize wind noise in outdoor applications. It is also supplied with a dual mounting block with attached tie bar.

Subminiature lavalier design; ideal size for theater, television broadcasting, video, film, and sound reinforcement

Small, inconspicuous mounting hardware

Full, clear sound comparable to larger microphones

Smooth extended frequency response with presence rise specially tailored for chest-worn microphone operation
