Functional characteristics

★ EA200 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: The system uses GFSK RF wireless transmission technology, operating frequency: 2402 ~ 2480MHz (commonly known as 2.4G);

★ microphone switch with touch-button design, long time no signal status with automatic shut-off feature to avoid battery loss and damage caused by forgetting, using a large-capacity lithium-ion battery, a charge can be used continuously for 8-12 hours;

★ recorder microphone unit application design principles, using imported microphone core and DSP audio processing circuitry, excellent pickup distance and perfect sound reduction;

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

★ advanced triple function mini-USB port, wireless transmission of voice and music as well as to prevent accidental access;

★ integrated laser pointer and PPT flip function, a unique black screen function key (and supporting the use of PPT receive keys) to increase the teaching of practical and vivid;

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

★ with audio input and output capabilities, easy real-time audio recording;

★ wired microphone interface supports phantom power, the real energy-saving and environmental protection;

★ box comes with gourds hanging, easy installation, and maintenance works effectively enhance efficiency;

★ broadcast signal priority system function;

★ support a group of speakers paired with multivessel microphone, easy to use, (ie: the microphone and host have any automatic pairing, lock function, multi-branch microphone while pairing the nearest preferred, after pairing, between any microphone and do not interference);

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

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

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

★ The built-in antenna, the installation more convenient, more stable performance.
