Description:

The device features a built-in receiver and four handheld microphones, utilizing digital UHF transmission technology for low bit error rates and high transmission stability. It also boasts strong anti-interference capabilities, uses ID code pilot technology to prevent co-channel crosstalk, and can be scanned to avoid interference . It offers flexible power options, including USB-C direct charging, a dedicated charging cradle , and AA batteries (compatible with NiMH, alkaline, and lithium batteries) . It's suitable for conference rooms, lecture halls, theaters , karaoke, concerts, and dance halls .

Features:

* Based on digital UHF transmission technology, pi/4-DQPSK modulation, and domestic main control chip, it has a transmission distance of 80 meters; it has reverberation, equalization, intelligent mute, audio encryption, and power regulation functions.

* It features one receiver and four handheld transmitters, operating in two frequency bands: 540MHz-590MHz and 640MHz-690MHz. The transmitters are ergonomically designed, with a rounded shape that fits the curve of your hand for a comfortable grip.

* It has audio encryption function. After it is turned on, the transmitter and receiver use unique ID code pilot encryption technology to achieve the effect of no cross-frequency communication between devices.

* It has multi-band equalization adjustment function, 2197 types of equalization adjustment, microphone equalizer adjustment function, with three adjustment gears of high, medium and bass, and each effect supports 13 gears of adjustment.

* It has an automatic mute function. When the microphone is dropped or thrown, it will automatically mute in milliseconds to avoid impact sound. It monitors the device posture in real time, mutes after 5 seconds of rest and shuts down after 8 minutes, without manual intervention.

* It has an automatic frequency scanning function, which can quickly find a clear frequency for the transmitter and is easy to operate.

* Easily pair transmitters and receivers via infrared scanning and sync.

* It has multi-level reverberation adjustment function, 15625 reverberation effects, effect ratio, reverberation delay, and reverberation amplitude adjustment. Each of the three sound effects has 25 levels of adjustment.

* The receiver has two balanced outputs and one unbalanced mixed output to meet the different needs of users.

* The receiver's front panel features four TFT-LCD displays, four encoder knobs, four frequency scan buttons, four IR binding buttons, a power button, and a two-in-one indicator light (IR transmitter + binding indicator). The rear panel includes one LINE-OUT port, four XLR-OUT ports, four BNC ports, and a DC input. The transmitter has an OLED display, a power/mute button, and two status indicators.

* The receiver features four 2.2-inch TFT-LCD displays, allowing users to easily view device RF signal strength, audio signal strength, microphone on/off status, handheld microphone battery level, current frequency, volume, language switching options, and more, providing current device information .

* The transmitter has a 0.96-inch OLED display that can display frequency information, audio encryption status, power level, mute status, and battery level information.

* The transmitter offers flexible and diverse power supply options, including a Type-C charging port that supports direct Type-C charging, charging with a dedicated charging dock, and powering with AA batteries (compatible with NiMH/alkaline/lithium batteries) to meet the needs of different scenarios .

* The transmitter's transmission power is adjustable from 1 to 7 levels, and the transmission power can be adjusted as needed to meet the needs of different scenarios.

* It has a one-touch mute button. Short press the button to turn the transmitter mute function on or off.

* The receiver panel is made with exquisite craftsmanship and looks elegant and beautiful; the microphone uses a high-fidelity dynamic microphone core and a professional sound cavity design, and the sound quality presents natural original sound.

* It has an ID code anti-crosstalk function and uses a 32-bit unique ID code for receiving and transmitting pairing. The sending and receiving ID codes must be the same for pairing, which can effectively prevent signals of the same frequency from crosstalking with each other.

* With long battery life, the transmitter can be used continuously for up to 10 hours.
