Williams AV IRH-35 Handheld Infrared Microphone, Channel A or B Selectable

The Williams AV IRH-35 is a durable, student-friendly handheld infrared microphone/transmitter designed for classroom interaction.

Featuring ten strategically placed emitting diodes, it delivers 360° IR coverage for reliable connectivity across a typical learning environment.

Channel selection via a slide switch (A or B) enables flexible pairing with the receiving system. The convenient battery-level LED—green for usable charge, red when needing recharge—and the simple on/off slider switch make it intuitive for daily classroom use. Powered by two rechargeable AA NiMH batteries, the IRH-35 delivers about 7 hours of operation per charge.
