Tabletop conf mic with 3.5mm plug. for PPA T46 PPA T27 or IR T2 only.

Ideal Use Cases

The Williams AV MIC 149 is a tabletop conference microphone specified exclusively for the PPA T46, PPA T27, or IR T2. Its omnidirectional polar pattern makes it appropriate for compatible tabletop applications in which sound may reach the microphone from multiple directions. Because the stated compatibility is limited to these three models, it is best suited to installations already using one of those designated Williams AV products.

Measuring 60 mm in diameter and 16 mm in height, the MIC 149 provides a low-profile tabletop format. Its black finish is suitable for conference tables and other surfaces where a compact microphone is preferred. The attached 39-inch (99 cm) cord provides a defined connection length for positioning the microphone relative to the compatible equipment.

Why Choose This Model

The MIC 149 combines an electret microphone element, omnidirectional pickup, and a 3.5 mm mono plug in a purpose-specific design. These published details make it possible to confirm the microphone type, connector, electrical requirements, and physical dimensions before purchase. It is a practical choice when the installation specifically calls for a tabletop microphone matching the listed Williams AV compatibility.

Its specifications include an output impedance of 1500 Ω, a sensitivity rating of 40 dB ± 3 dB, and a bias power requirement of 1.0-10 VDC. These values should be compared directly with the intended system requirements when planning an installation or replacing an existing microphone.

Installation and Integration

Integration begins with confirming that the connected model is a PPA T46, PPA T27, or IR T2, since the product information identifies the MIC 149 for those models only. The microphone terminates in a 3.5 mm mono plug. Verify the connection type and compatible model before inserting the plug, particularly when other equipment in the installation may also use similarly sized audio connectors.

The microphone requires 1.0-10 VDC bias power. Its 39-inch (99 cm) cord should be considered when determining tabletop placement and the distance to the connection point. The circular housing measures 60 mm across and stands 16 mm high, allowing its required surface area and cable path to be planned in advance.

Performance Highlights

The electret element is paired with an omnidirectional polar pattern. Rather than specifying a single directional pickup orientation, the published pattern indicates pickup around the microphone. This is a relevant characteristic for tabletop conference use, where the microphone may be positioned between participants or where the sound source is not fixed to one direction.

Published electrical specifications include 1500 Ω output impedance, 40 dB ± 3 dB sensitivity, and a 1.0-10 VDC bias power range. Together with the mono 3.5 mm connection, these details provide the core information needed to evaluate the MIC 149 against a compatible setup.

What Makes It Different

The MIC 149 is defined by its focused compatibility and tabletop form. It is not presented as a general-purpose microphone for unspecified devices; the source information restricts its use to the PPA T46, PPA T27, or IR T2. That distinction is important when selecting among microphones that may share a 3.5 mm connector but have different electrical or system requirements. Its compact 60 mm by 16 mm black housing, omnidirectional pattern, electret type, and attached 99 cm cord establish a specific physical and technical profile.

Final Assessment

The Williams AV MIC 149 is a compact black electret conference microphone for compatible tabletop installations. Its key selection points are the omnidirectional polar pattern, 3.5 mm mono plug, 39-inch cord, 1500 Ω output impedance, 1.0-10 VDC bias requirement, and 40 dB ± 3 dB sensitivity. For users of the PPA T46, PPA T27, or IR T2, it offers clearly documented dimensions and connection requirements. The product carries a 90-day warranty.
