DSP Digital Teaching Amplifier

DS-80/80A-80B DSP Digital Teaching Amplifier

System Host Introduction:

DS-80 are designed and manufactured specifically for the teaching amplifying sound equipment, integrated DSP digital feedback suppressors, filters, pressure limiter amplifier, such as a lot of advanced digital audio technology. It can enhance the sensitivity of the microphone by 6 to12dB, the microphone’s adapterization’s distance can add by 3 to 6 meters. Installed 1 to 3 units of interface microphones on the platform, teachers without bringing any equipment can be easy to amplify sound and reduce teacher’s occupational diseases due to speaking excessively. It improves sound field of classroom and improve the quality of teaching. Every student can listen clearly. Equipments’ design is according to setting a number of human. With JMC-290A / B dedicated microphones, Teachers can adjust the volume and mute of the microphone cabinet without opening the control ark. The microphone can connect audio signals of the notebook and play directly. It is convenient to teach without special management.
