Meeting microphone for conference rooms
The Philips LFH9172/00 is a boundary layer electret condenser microphone designed for tabletop use in meetings. Its 3.5 mm connector plugs directly into compatible audio inputs without a separate stand. The 360 degree pick-up pattern captures voices from every direction around the device. Dark grey and silver finish suits professional environments.
Two-metre cable with built-in wire storage
A 2 m / 6.5 ft cable includes integrated length adaptation so excess wire stays tidy on the table. Units can be cascaded to extend coverage for larger rooms without extra mixer channels. Phantom power operates between 1.5 V and 5 V at 0.5 mA, drawing minimal current from the host device. RoHS compliant and lead-free soldered construction meets current environmental standards.
Check your input provides plug-in power
Verify that the 3.5 mm jack on your recorder, PC sound card or conference phone supplies 1.5–5 V phantom voltage; passive inputs will not power the capsule. Ensure the frequency response of 30 Hz–18 kHz matches the clarity you need for speech recording. Confirm that a single boundary microphone covers the intended seating area or plan for cascading additional units.

Questions about this item
Will the electret condenser capsule or 3.5 mm plug need periodic replacement?
The electret condenser capsule is a solid-state component with no moving parts and the 3.5 mm connector is rated for repeated insertion; neither has a scheduled replacement interval.
What limits continuous operation first — the 1.5–5 V phantom supply or the 2.2 kOhm impedance?
The 1.5–5 V phantom supply at 0.5 mA sets the maximum cable length and number of cascaded units before voltage drop degrades the -38 dBV sensitivity.
Does the boundary-layer design stay cool and silent during all-day meetings?
The microphone draws only 0.5 mA from the 1.5–5 V phantom supply, so it generates no audible noise and negligible heat during extended use.
