Infrared microphones are the best choice for teachers, especially during Covid-19.
In addition to the challenges presented by physical barriers like masks and distancing, many teachers will be rotating rooms and shared devices must be sanitized after every use.
Not only do TeachLogic microphones overcome the physical barriers, thanks to infrared (IR) technology they:
- Enable a teacher to use the same microphone in every room.
- Prevent the need for sharing between teachers.
- Simplify the deployment of microphones for the entire school.
Speed and Bandwidth
IR delivers unmatched speed in audio transmission. Our next generation technology drives wireless audio beyond any other technology, with utmost clarity.
Light can be contained and secured in a physical space. It (doesn’t not?) penetrate walls and spill into other rooms incidentally.
Quality of Connection
IR provides enhanced reliability enabling interference-free communications and increased audio definition, dramatically improving the user experience.
Unlike Radio Frequency (RF), IR technology does not pass through solid walls. No pairing is required. Simply push the power button, and the system is on immediately. Walk into a classroom and you are “paired”; walk out and you have full privacy.

|Benefits of IR||Why it Matters|
|High Fidelity: Infrared systems can transmit/receive a full range of sound frequencies (frequency response), enabling a more accurate reproduction of audio sources like a person’s voice.||Why fidelity matters: Unvoiced consonants (f, s, t etc.) lie in the frequency range 2– 8 kHz. For students to understand speech clearly, they must have good hearing across the entire range of frequencies from 125 – 8 kHz. Most radio systems have a max of 7 kHz.|
|Low Latency: Latency is the delay before the transmission of sound. Because IR is light based, the transmission of the teacher’s voice from the microphone to the sensor is much faster than radio waves.||Why latency matters: If you have ever watched a video and noticed the person’s speech doesn’t match their lips, then you can imagine what happens if the teacher’s voice doesn’t their lips. Even a slight delay can affect comprehension. Most radio systems have ~17 ms latency whereas TeachLogic IR = 0.8 ms.|
|Wall permeation: Because IR transmission is light based, it does not pass through solid walls.||Why permeation matters: Radio waves can travel through all adjacent rooms. This can create interference and/or inadvertently “leak” the communications into nearby rooms. IR stays in the intended room and conversely stays out of other rooms. Privacy matters.|
|Channel management: Because IR transmission stays within the walls, the same channels can be used in every room. The microphone is “paired” as soon as it enters the room.||Why channels matter: With IR, any microphone can work in any room. Radio systems require that microphones are manually paired in each room and will only work in that room unless unpaired and paired again in a new room.|
Other benefits of TeachLogic
Lightest pendant microphone available
Microphones are paired and ready for every classroom
The same microphone supports in-class and distance learning
No Audio Dropout Guarantee
When a Sapphire microphone is used with an ICS-55 ceiling sensor, if audio dropout occurs in a standard classroom (enclosed classroom up to 1600 square feet with ceiling heights of 12 feet or less), TeachLogic will provide additional sensors at no charge.
