EA1133 Classroom Sound re-inforcement in the classroom is simple to achieve with the EA1333 IR system connected to an existing amplifier - a highly effective method of improving the attention and academic results of pupils and students.

The EA1133 Classroom Sound Re-inforcement Infrared Microphone system overcomes the problem of interference between systems in adjacent classrooms that are suffered by VHF wireless systems

A lightweight teacher microphone with a lanyard and clip is unobtrusive and easy to use.
The system is plugged directly into the existing classroom speakers systems, so saving additional expense.

The high sensitivity microphones use standard AA size rechargeable batteries which last for 6-8 hours continuous use. The microphones are identical so can be used by the teacher or pupils. Two channel selector and on/off switch included on microphone.
