745 EL2 System User Guide 2/24/04 4:29 PM Page 7 introduction Congratulations on the purchase of your new EasyListener 2 sound field system! With proper care and use it will become one of your most valuable classroom tools for many years. Students will be able to consistently and easily understand what the teacher is saying, regardless of his/her location in the classroom. Teachers can now speak all day in their normal voice and will suffer far fewer vocal problems as a result.
