Williams Sound . DWS TTS 2 300

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 300 transceiver has a built-in microphone and speaker.) Teacher always controls the presentation. Four independent groups can be operating simultaneously within a range of up to 200 feet outdoors/300 feet indoors (in 1- or 2-way mode, depending on environmental conditions). Outside of this range, other groups can be in operation. (i.e., four adjacent classrooms). Set-up lock (SLOC) enables administrator to lock each DLT 300 to prevent unauthorized changes to a Digi-Wave system set-up. Four digit secure key, entered into each group members DLT 300, prevents unauthorized individuals from listening in on the group.
