Overview
Tan, with 4-foot (1.2 m) Cable
Model WL93 Microphones are economical omnidirectional, subminiature, lavalier, condenser microphones designed for general speech applications where a visually unobtrusive microphone is desirable. All WL93 models are supplied with a mounting block with attached tie bar, a sew-on mounting bracket, and an acoustic windscreen to minimize wind noise in outdoor applications. All WL93 models include a cable terminated with a 4-pin mini connector which connects directly to a Shure wireless body-pack transmitter.
Key Features
- 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
- Controlled low-frequency rolloff reduces low-frequency clothing and room noise
- Low distortion, wide dynamic range
- Uniform omnidirectional polar pattern
- Preamplifier assembly (SM93) can be pocketed, strapped to the body, or clipped to belt or waistband
- Wide-range phantom powering (SM93) accepts all commonly used voltages
