Product Description
True Diversity Wireless Microphone System Handheld Microphone
DESCRIPTION This is a true-dimension U-segment wireless microphone system that pursues high quality and high stability. The sound is clear and transparent, clean and transparent, and the frequency response is wide and straight. It is suitable for different speaker systems; the microphone is not used for the speaker. The sound of a firecracker is similar. The super-cardioid capsule with anti-feedback function can express the sweet and mellow vocals and the emotional details of the singing speech. It is the ideal partner for singing and speech.
The operation interface of the receiver is simple, using graphical and menu selection operation modes, all displayed on the screen; turning the flywheel, moving the cursor, pressing the flywheel key to change the function parameters corresponding to the corresponding icon, and then pressing the flywheel to confirm the saved parameters. There are 8 function icons: channel, quiet, gain, sweep, lock, frequency, power and frequency modification; transmitter's power, signal strength and antenna status, full monitoring; there are 2000 password-added communication frequencies, Optional, automatic scanning; digital combination of digital pilot and noise reduction technology to eliminate wireless signal interference.
FEATURES
1. System function setting, using menu operation.
2. The receiver and transmitter are housed in a rugged metal enclosure.
3. The receiver preset stores 200 fixed frequencies; 2000 freely set frequencies, arbitrarily selected according to the 25 kHz frequency step interval, communication plus password.
4. Auto scan function, automatically find available frequencies without interference when linking.
5. Receiver and transmitter, one-button automatic frequency matching, the frequency of success is marked on the receiver screen.
6. The receiver monitors the transmitter's working status by wirelessly transmitting control signals in synchronization with the transmitter settings:
For example, the receiver monitors the power of the transmitter; monitors the off or on state of the transmitter; and sets the power of the transmitter.
7. High-quality true diversity receiving technology, the signal is unblocked anytime, anywhere, stable and uninterrupted.
8. Digital sound technology and noise quiet technology to prevent interference from wireless RF signals.
9. MDX cooler, unique compression and extended audio processing technology, make the sound clear and transparent.
10. The receiver sets up four wireless signals to receive high-frequency amplifiers to ensure wireless signal transmission.
11. Graphical system lock function to avoid changing system settings at any time.
