Unidirectional headband microphone. Improve

The Williams AV MIC 100 is a sleek, lightweight unidirectional headset microphone designed to provide high-quality audio for FM assistive listening and interpretation systems. Its electret-condenser element, head-worn format, 3.5 mm mono connection, and published 50 Hz–16 kHz frequency response create a focused solution for compatible spoken-audio applications.

Ideal Use Cases

The MIC 100 is intended for FM assistive listening and interpretation systems where a headset microphone keeps the microphone positioned with the wearer. Williams AV recommends this model for the T27 transmitter and T46 transmitter. These listed pairings make the microphone relevant for users assembling or maintaining systems built around either transmitter.

Its uni-directional pick-up pattern is designed to favor sound arriving from a specific direction. This characteristic is useful in applications centered on the wearer’s speech. The lightweight 0.35-pound construction also supports situations in which the microphone may be worn during an extended presentation, interpreted session, or assistive-listening program.

Why Choose This Model

The MIC 100 combines an electret-condenser element with a compact headset configuration. It does not require phantom power, an important connection detail when planning how the microphone will integrate with a transmitter or audio system. The black finish gives the headset a restrained appearance, while the sleek form keeps the design appropriate for spoken communication.

Williams AV provides concrete operating specifications for system planning. The microphone has a stated frequency response of 50 Hz–16 kHz, sensitivity of 70 dB ± 3 dB, and listed impedance of 600 W. These published values allow installers and system owners to document the microphone alongside the rest of their equipment.

Installation and Integration

Connection is made through a 3.5 mm mono, right-angle plug. The right-angle format changes the direction in which the connector and cable exit the connected device, while the 47.3-inch cord provides a defined cable length for positioning the microphone relative to the transmitter.

For the manufacturer-recommended configuration, pair the MIC 100 with a T27 or T46 transmitter. When considering other equipment, confirm that its microphone input and connector requirements match the MIC 100’s 3.5 mm mono plug and non-phantom-powered operation. This helps ensure that the physical connection and input requirements are considered before installation.

The listed replacement windscreen is Williams AV model WND 009. Recording that part number can simplify identification when a replacement windscreen is needed during ongoing system maintenance.

Performance Highlights

• Electret-condenser microphone element
• Uni-directional pick-up pattern
• Published frequency response of 50 Hz–16 kHz
• Published sensitivity of 70 dB ± 3 dB
• Listed impedance of 600 W
• No phantom power requirement
• 3.5 mm mono, right-angle plug
• 47.3-inch attached cord specification

These specifications define the MIC 100 as a purpose-built headset microphone for speech-oriented Williams AV applications. Its directional pattern, head-worn design, and stated response range are combined in a single lightweight microphone intended for assistive listening and interpretation use.

What Makes It Different

The MIC 100 is distinguished by a focused set of features rather than unnecessary complexity. It brings together a uni-directional capsule, headset positioning, a mono right-angle connector, and compatibility recommendations for two Williams AV transmitters. At 0.35 pounds, it remains lightweight while supplying a 47.3-inch cord for connection.

Additional ownership details are clearly identified: the product carries RoHS approval, includes a 90-day warranty, and uses the WND 009 as its listed replacement windscreen. Together, these details help purchasers evaluate not only the microphone’s core audio specifications but also its integration and replacement-part requirements.

Final Assessment

The Williams AV MIC 100 is a practical choice for users who need a lightweight, uni-directional headset microphone for FM assistive listening or interpretation systems. Its electret-condenser element, 50 Hz–16 kHz frequency response, non-phantom-powered design, and 3.5 mm mono right-angle plug provide a clearly documented configuration. For systems using a T27 or T46 transmitter, it is the specifically recommended microphone model in the supplied product information.
