Functional characteristics

 EA300 integrated digital amplifier, hi-fi speakers and 2.4G digital wireless microphones. Powerful, easy to install, easy to use and is ideal for teaching and presentations multifunction devices. The main technical characteristics are as follows: using GFSK RF transmission technology, 2402 ~ 2480MHz (commonly known as 2.4G technology), multiple sets using no string frequency and reducing sound quality is good, stable and reliable transmission; reliable speaker system, excellent voice and music performance;

 speaker system with two-way line input, the way in which the broadcast signal has priority;

 microphone and host have any automatic pairing, lock function, multi-branch microphone while pairing the nearest preferred, after pairing, between any microphone without disturbing each other;

 microphone paired with the host and lock distance of not less than one meter, time is not more than one second;

 microphone switch with touch button design, long time no signal state will automatically shut down to prevent battery loss and damage caused by forgotten;

 recorder microphone unit application design techniques, the use of imported microphone core and DSP audio processing circuitry, excellent pickup distance and perfect sound reduction, small and exquisite appearance;

 equipped with LCD display, more intuitive grasp of equipment working conditions;

 advanced triple function mini-USB port, wireless transmission of voice and music;

 microphone with the host after successful pairing prompts the user through the screen flash and sound manner;

 integrated laser pointer and PPT flip function, flashlight-style button design, easy to operate laser pointer; unique to a black screen function key (and supporting the use of PPT receive keys) to increase the teaching of practical and vivid;

 same place a lot (1,000 units and above) and do not use string frequency;

 microphone small and exquisite appearance, support folders, multiple use headphones, hand-held and other means.
