The BrauLAB LS401-WM Language laboratory set is specially designed for foreign language teaching.

It is a communication platform that allows teachers and students to cross-talk with each other and present monologue and dialogue authorities on demand. LS401-WM is a much more economical sound system that can be set up without computers for each student.In this system, student units can be mounted on walls.

Speech of the teacher can be heard by all students through headphones. When students want to talk they can push the call button on the student panel. The teacher can give permission to speak through the teacher's control panel. The authorized class can hear the entire class of this speech. If desired, the teacher can authorize two students, so the dialogue between the two students can be heard by all of the students.
