Description
PORTABLE WIRELESS MEETING/TEACHING AMPLIFIER
MODEL: JPA-280 USB
Features:
- Rationalization of exterior design, reservoir batteries, wireless receiver, power amplifier, speaker output in one, portable to carry.
- A unique “sound code and noise lock” dual mute controls.
- Condenser microphone, receiver sensitivity, good pickup effect.
- Quartz oscillator, frequency locking stability, not drift.
- VHF Professional Microphone high frequency sound transmission, setting super anti-jamming
- Encounters with native differ 0.5MHz signal no interference.
- Lavalier and unilateral ear hook microphone, easy to use, beautiful, pickup works well, even if it is a
- weak voice, but also to clear broadcast.
- Reverb device, making the sound loud and clear sounds.
- LED undervoltage auto show, timely charge, to protect the battery.
- You can use audio-visual connection with the media.
- The latest IC circuit chip power consumption, low cost, inexpensive.
- The most suitable presentation, meeting, teaching, selling farm, church …. meetings, recording, sound
- Recording
