Say goodbye to the trouble of off-frequency performance, why has the true diversity UHF wireless microphone become the industry's just need

First, the general pain point in the industry: the failure of wireless microphone is a common problem for almost all operators in the microphone pits that countless businesses have stepped on, whether it is KTV boxes, commercial performances, corporate lecture halls or music restaurants: 1. The mobile frequency is off, and the sound is stuck. Traditional single-antenna wireless microphone, when the stage moves, the wall is blocked, and the crowd is blocked, there will be a dead corner of the signal. The singer walks to both sides of the stage and suddenly loses his voice in the middle of the conference speech, which seriously damages the live experience. 2. When multiple sets of microphones are used at the same time in the same venue with multiple devices in series frequency and mutual interference, the frequency points of cheap models overlap, resulting in two microphones in series sound; In-store WiFi, Bluetooth, and radio frequency signals of monitoring equipment continue to interfere with radio reception, accompanied by harsh noises. 3. Howling is difficult to control, and the loss of audio equipment is unbalanced. When it is close to the speaker, it will produce high-frequency howling immediately. Long-term howling will burn the tweeter and increase the maintenance cost of the store equipment. 4. Short battery life and uneven quality control. The battery life of the low-end microphone is only 2-3 hours, and the battery needs to be changed frequently in the middle of large-scale activities; The microphone core assembled by small factory is easy to be distorted, and the voice is stuffy and the sound is obviously broken after half a year's use. These problems seem trivial, but in fact they directly affect the store's reputation and performance effect, and frequent after-sales maintenance will continue to increase operating costs. The true diversity UHF wireless microphone is a professional solution to all the pain points.

Second, the core technology analysis: true diversity+UHF double blessing
1. UHF gold band, isolated from daily electromagnetic interference.
The product adopts the exclusive UHF frequency band of 610-670MHz, avoiding the crowded frequency band of 2.4G Bluetooth, WiFi, monitoring and mobile phone signals, and optimizing the wiring of RF isolation circuits, greatly reducing the interference of environmental clutter.
Compared with the 2.4G civil microphone on the market, UHF transmission has stronger penetration, and the signal attenuation is reduced by 70% in the environment of partition wall and multi-person occlusion, and the adaptability of complex scenes such as restaurants and multi-box KTV is full.
2. Dual-antenna true diversity reception, completely eliminating the dead angle of frequency cutoff.
The receiver is equipped with two sets of independent RF receiving circuits and double external high-gain antennas. When working, the signal strength of the two antennas is compared in real time, and the channel with more stable signal can be seamlessly switched within 3 ms..
Different from the short board of "single channel reception" of ordinary single antenna microphone, even if the user walks around freely, the wall is blocked and the large stage is used for a long time, there will be no sound jam and loss of voice. The visual transmission distance can reach 100 meters, meeting the needs of various large-scale indoor and outdoor venues.
3. Intelligent automatic frequency sweep+infrared frequency matching, and multiple sets of frequencies in the same field are not connected in series.
Built-in PLL phase-locked loop multi-channel synthesis chip, a single set of host built-in 200 groups of adjustable pure frequency points; Start-up one-button SCAN to automatically scan the frequency, automatically screen the blank channels without interference on the spot, and infrared one-button synchronize the microphone and receiver frequency.
More than 10 sets of equipment are deployed in the same space at the same time, and there will be no frequency point conflict and crosstalk, which is suitable for chain KTV, large-scale exhibition and multi-conference room commercial scenes.
4. Customize the moving microphone core to suppress howling and restore the original voice.
Adopt 30mm thick gold-plated moving coil microphone core, with built-in DSP voice equalization algorithm, optimize the mid-frequency voice gain, the high tone is transparent and not harsh, and the low tone is full and not turbid; Built-in feedback suppression module can effectively reduce the howling probability of short-range pickup without additional complicated tuning equipment.
K-song, speech and stage singing are well-balanced, and ordinary people can gain clean and natural radio effects without professional tuning skills.

Third, full scene adaptation, covering all commercial needs
Commercial KTV, music bar
One-for-two standard suit, standby battery life for 8 hours, rechargeable lithium battery recycling, saving the cost of frequent purchase of disposable batteries; The metal fuselage is wear-resistant and fall-resistant, which is suitable for high-frequency daily use and reduces the frequency of equipment replacement.
Enterprise lecture hall, school auditorium
Multi-channel, one-trailer, four models, to meet the needs of multi-person speech and teacher-student interaction; The signal is stable without noise, and the radio reception is clear for a long time. It has its own digital display screen to check the channel, power and signal strength in real time.
Outdoor Shang Yan, small band stage
Long-distance stable transmission, anti-crowd, wall occlusion; The anti-slip and anti-slip design of the fuselage makes it difficult to get rid of the performance process, which is suitable for outdoor night markets, roadshows and small music festivals.
Family K songs, live room recording
Lightweight body, simple operation, one-button boot pairing, compatible with power amplifier, mixer, sound card, portable audio, home entertainment, short video live broadcast can be used.

Fourth, the advantages of factory quality control, foreign trade procurement and offline business optimization
Enping city Nuoyin Electronics, as the original manufacturer of audio equipment, has independently developed and produced a full range of wireless microphones from microphone core, RF motherboard to metal shell, and each equipment has undergone three rigorous tests:
72-hour aging power-on test, simulating uninterrupted use throughout the day, and screening defective products with battery life and unstable signal;
Full-band interference simulation test, replica of complex RF environment in KTV, exhibition and shopping mall to verify anti-interference ability;
Drop, wear resistance, high and low temperature environment test to ensure long-distance sea transportation and long-term commercial durability.
The product has a complete set of CE, FCC and ISO9001 certifications, supports OEM/ODM customization, and can customize the brand LOGO, body color matching and functional parameters to meet the bulk purchasing needs of overseas distributors and domestic chain stores.
