Pairing (pairing ID code + pairing frequency):
The “Frequency Hopping Mode” is a brandnew operation mode introduced
by this program. The data is sent wirelessly by the hand microphone to the
receiver for pairing. After the pairing is successful, the frequency point of the
hand microphone will switch between these 10 frequency points.
The hand microphone can manually change the frequency at any time.
The receiver will automatically follow and jump to the corresponding frequency.
In this way, it not only solves the crosstalk problem, but also provides the
exibility of frequency setting. Products using frequency hopping have been
widely recognized by the market and meet the requirements of most products.
KTV rooms, hand boxes, teaching, personal entertainment and other occasions
to be applicable.
Performance and Characteristics
1. UHF 500MHz-938MHz frequency band is used.
2. Using one-dimensional code + frequency for data encryption and frequency
(even when the same frequency is used to receive, the internal chip and is
interfered by RF, it will only aect the connection range. If the two receivers
are separated by a certain distance (for example, 10 meters), the frequency
re-use can be considered.
3. With automatic mute and impact elimination circuit, help to avoid the impact
and noise of the mic switch.

4. The hand microphone has an LED digital tube display function that can
intuitively display the current frequency.
5. The eective distance of wireless transmission is 50-80 meters.
6. The handheld microphone adopts lithium battery circuit design, with
overcharge and over-discharge protection.
7. The simple operation interface and few adjustable parts can completely
avoid malfunction caused by incorrect operation.
8. The transmitter has a low-voltage detection function.
When the battery voltage drops to 2.2V, the battery character ashes.
9. Extremely high pickup sensitivity and excellent sound quality make it easy
for you to speak or sing.
10. Multiple devices can be used at the same time, no interference and cross-
frequency phenomenon.
11. With power and wireless indicator lights.

Sound Quality
This way of connection can achieve the sound quality eect as using wired
connection, its eect can be very close. No compression or expansion is
needed to preserve the original sound. The frequency response, transience
and linearity of the sound are excellent, very close to the sound quality of the
wired microphone.
Crosstalk
The wireless microphone uses all-digital wireless transmission chip which is
dierent from the tradional modulation and demoduation method which
keeps the sound real. The system’s transmitter and receiver chip uses digital
encryption for transmission even if the same frequency is used.
As long as the ID code is set dierently, there will be no crosstalk.
