THIS SYSTEM DOES NOT INCLUDE SPEAKERS.  The  transmitter/receiver box in the diagram below plugs into any installed speaker system with included RCA cables.

The Revolabs Classroom Wireless Amplification System allows the teacher to speak in a normal voice and the students can hear every word. The System will automatically select RF channels to avoid interference; it does not require the teacher to change channels to avoid interference as with IR Systems. Classroom System can be easily adjusted to the appropriate power setting to allow systems to be used in adjacent classrooms.

This Classroom Amplification System includes a Revolabs RF Armor™ Wireless Wearable Microphone (impervious to GSM noise from cell phones and PDAs). It is small and ultra light, measuring just 2.5 inches high, about one inch across and weighing mere ounces.  Also, it is impervious to GSM noise from cell phones and PDAs.

The Revolabs Wireless Microphone is rechargeable and the battery provides eight hours of talk time, a full school day, so there are no batteries or battery packs to worry about.  A recharge to 85 percent capacity can be attained in about 45 minutes.

Once installed, the teacher or professor simply removes the Wireless Microphone from the Charger Base, clips it on a lapel or the lanyard provided, and un-mutes the System by pressing the Mute Button on the microphone.  The microphone is muted when it is removed to eliminate any noise that may occur while the teacher puts the microphone on.  The Mute Button is very accessible and can be turned on and off easily.  When finished with the microphone, it is placed back in the Charger Base to recharge.
