The Shure Model WH30 is a Light Yet Rugged Headset Microphone.

Model# SU-WH30XLR

The Shure Model WH30 is a light yet rugged headset microphone. Designed for vocalists and instrument-playing vocalists, the WH30 utilizes a high quality electret-condenser cartridge suitable for all applications where mobility, comfort, low microphone-visibility, and high sound quality are required. Because of its cardioid (unidirectional) pickup pattern, the WH30 provides isolation from extraneous sound sources and high gain-before-feedback. The wireframe and gooseneck adjust to any head size and shape. An integrated elastic headband comfortably pads and secures the headset. The WH30 is supplied with two snap-on windscreens, clothing clip, storage bag and cable-management device. The WH30 is a perfect fit for those who desire total freedom of movement and need the high-quality audio of a condenser microphone.

Features
• Tailored frequency response enhances vocal range	• Cardioid polar pattern provides maximum gain before feedback
• Flexible gooseneck for optimum microphone placement	• High sound pressure level capability
• Isolation shock mount reduces vibration noise	• Secure snap-on windscreen reduces "p" pops
• Low-profile, lightweight design	• The RPM420 preamp requires phantom power from any 11 - 52 V source. (WH30XLR)
