Simultaneous, two-way, wireless team-teaching system in the 2.4 GHz band. Works well in a classroom where two or more teachers combine skills to teach as a team. One- or two-way communication with students is available: two teachers can speak simultaneously; student can hear both teachers; student can participate as listen-only or access 2-way mode with the push of a button. (Student participating in 2-way, push-to-talk mode does not need to wear a headset. The DLT 100 transceiver has a built-in microphone and speaker.) Teacher always controls the presentation.
