Wireless conference gooseneck microphone
Model:KU-230 Guangzhou Jodie Audio Equipment Co., Ltd.
1. UHF frequency band transmission signal, frequency range: 500MHz-900MHz;
2. Four channels receive signals, with 100 channels to choose from per channel, each channel stepping at 250KHz; Each channel uses 49.75MHz;
3. By adopting stable PLL digital phase-locked loop synthesis technology and intelligent digital circuits, the overall performance stability of the machine is significantly improved;
4. Each channel is equipped with a unique ID number to enhance anti-interference function and support the use of 5 stackers (i.e. 5 receivers and 20 transmitters);
5. Built in high-efficiency noise suppression circuit with significant anti whistling function;
6. Two rubber receiving antennas are installed on the back of the receiver to enhance the received signal and have a stylish appearance;
7. The back is equipped with 2 balanced outputs and 1 mixed unbalanced output, suitable for connecting various external devices;
8. It is no longer limited to pairing a single channel for one transmission, achieving interoperability among 400 channels for the same transmission, showcasing a humanized high-tech design;
9. Silent touch switch design, press lightly for 0.5 seconds to enter the working state;
10. Flexible gooseneck microphone design, adjustable 360 ° in all directions, and the microphone light ring indicates the speaking status.
11. The microphone consumes 80mA and is powered by 3 1.5V batteries, which can be used continuously for 12 hours;
12.Both the host and transmitter are equipped with LCD screens to display the working status and other related information
13. Usage distance: Open environment: 80-100 meters Complex environment: 50-80 meters
14. Suitable for various conference and speech occasions.
1: Adopting UHF ultra-high frequency band and dual receiving digital pilot technology, it has less interference and more reliable transmission compared to traditional VHF frequency band;
2: DPLL digital phase-locked loop multi-channel frequency synthesis technology provides up to 200 channel options at 250KHz channel intervals within a 50MHz frequency bandwidth, making it convenient for multiple machines to use simultaneously and easily avoiding various interferences
3: Advanced automatic frequency matching technology, even if the frequencies of the transmitter and receiver are scrambled, you only need to press lightly, and the transmitter will automatically lock the receiver frequency and adjust it to be consistent, making it easy to use
4: Specially designed high and low power switching function, high-power transmission is used for large performances (venues over 1000 square meters), and low-power transmission can be used for small performance venues to save battery power;
5: Specially designed receiving sensitivity adjustment function, which can adjust sensitivity as needed to improve anti-interference ability or increase receiving distance;
6: The usage distance can reach 200 meters;
7: Automatic search for interference free frequency points function;
8: One click frequency locking to prevent accidental operation during use;
9: Electronic volume control, adjustable range 0-39, 2dBm per step;
10: One click installation mode, with 100 sets of installation frequency points built-in, making it convenient to set multiple frequency points simultaneously;
