With Voice Amplification Mode, an instructor wearing a wireless headset microphone connected to an HDL300 or Dual HDL300 will have an amplified voice in the room. The HDL300 system's full-room audio pickup continues to ensure that remote participants hear all voices from the classroom clearly.

Why use Voice Amplification Mode?

Speaking all day can put a strain on the instructor's voice. Hearing an instructor clearly can also be challenging for students, especially those sitting in the back of the classroom. With Voice Amplification Mode, you can improve the in-room experience for both students and instructors while still providing an excellent audio experience for remote students.

With Voice Amplification Mode 

• In-room students can hear their instructor amplified clearly through the HDL300 speakers
• Remote students can hear their instructor and in-room classmates clearly through the UC&C application, thanks to the HDL300 system’s full-room audio pickup
• Everyone – instructor, in-room students and remote students – can be recorded with the UC&C application or lecture capture solution

NOTE: Only the voice of the person wearing the headset microphone will be amplified in the classroom.
