UF8740C
Product Description
2. Adopt stable PLL digital phase-locked loop synthesis technology and intelligent digital circuit to avoid interference frequency;.
3. Use frequency range: UHF 600MHz~699.75MHz, more suitable for a wide range of use.
3. Four-channel 400-channel receiving signal, each channel has 100 channels; each channel is stepped at 250KHz; each channel uses 49.75MHz;
4. Each channel is equipped with a unique ID number, which enhances the anti-interference function, and supports up to 20 simultaneous use (that is, 20 receivers and 80 transmitters);
5. The main panel is designed with a combination of metal + acrylic PVC, with 5 groups of function buttons to achieve multi-function operation.
7. Brown acrylic PCV, highlighting the three-dimensional light transmission of the Veidamic trademark, showing high-end fashion.
8. Quadruple screen LCD display, fashionable and clear, real-time feedback system working status;
Display content: display working channel, working frequency, RF receiving signal, AF audio signal, lock screen indication;
9. The receiver is equipped with 2 rubber receiving antennas to enhance the received signal and has a decent appearance;
10 There are 2 balanced outputs and 1 mixed unbalanced output on the back, suitable for connecting various external devices;
11. Separate panel corner code, free installation on desktop or upper cabinet;
12. It has a switch noise elimination circuit to avoid huge impact noise when the switch is turned on, and ensure the safety of the power amplifier system and the speaker.
13. With frequency search function, it is easy to select clean frequency points.
14. Manual locking or manual frequency locking function to prevent misoperation.
15. Ideal space use range; optional meeting, hand microphone, head wear, lavalier
16. Use distance: open environment: 80-100 meters, complex environment: 50-80 meters.
Direct viewing distance 100M (The actual range depends on the absorption, reflection and interference of the radio frequency signal by the environment.)
17. Suitable for conference rooms, command centers, hotels, schools, churches, etc. 1. Interoperability among 1600 channels, showing the humanized high-tech design; (the same transmitter can be interoperable in two, four and eight)
2. The appearance design of the advanced anti-true speaker network has high-end process standards of ABS new material and novel patented design;
3. Long tube: ergonomically designed metal microphone head cavity, with capacitor microphone core + self-created audio processing circuit, the sound is bright and the restoration is high. The gooseneck microphone pole and conference seat are detachable, which is convenient for disassembly and assembly, and can be flexibly replaced;
The down tube can be adjusted 360° in all directions, allowing more freedom of communication. The microphone pole light ring indicates the speaking status.
4. The 2.4-inch high-definition LCD display shows the working channel, working frequency, and current power status at a glance;
5. Unique finger-type button design, lightly press 0.5S to turn on and enter the working state;
6. The silent switch is used to effectively prevent the mechanical sound of the switch;
7. Built-in audio dual program, free switching between long tube and square tube modes.
8. Powered by 1.5V battery (3 capsules), low power consumption can last for 8 hours
