The adoption of Class D digital power amplifier and 30W high-efficiency speaker design makes the output sensitivity up to
92dB.
The speaker built-in echo tube design presents stereo sound in bass to make people immersed in the high quality surround
atmosphere and endless auditory feast.
High/low pitch optimization design, enhancing the response frequency in 50Hz and 20KHz range, regardless of high/low
pitch sound quality is clearly distinguishable allowing teachers and students to interact under the pleasant sound.
Patented design, unique two parts hook method, convenient
and easy installation
The speakers installed at the front of the classroom are in a dilemma that they can be heard clearly at front but blurred in

them in different classrooms. Therefore, the teacher can carry his own wireless microphone going to different
classrooms installed CH-30W speaker to use and the frequency is not interfered.

it in your hand without any heavy discomfort. Built-in high-sensitivity condenser microphone to create the clear sound
quality to let teacher or presenter behave well under the external noise or classroom fan.

automatically. After pairing the frequency is automatically locked to prevent from interference. Under pairing
microphone has 10M wireless distance so the teachers can freely teach around the classroom without any wire.
