AD4Q Wireless System Description:
1. Signal transmission in UHF band, frequency range: 600MHz-900MHz;
2. 4 channels to receive signals, each channel has 100 channels to choose from, each channel at 250KHz step; 12.25MHz per
channel;
3. Using stable PLL digital phase-locked loop synthesis technology and intelligent digital circuit, the performance and stability
of the whole machine are significantly improved;
4. Each channel is equipped with unique ID number to enhance anti-interference function, supporting the use of 50 overlapping
machines ( means 50 receivers and 400 Handheld transmitters);
5. Built-in efficient noise suppression circuit, anti-noise function is remarkable;
6. Two rubber receiving antennas are set on the back of the receiver to enhance the received signal with decent appearance;
7. The back is equipped with 2 balanced output and 1 mixed non-balanced output, suitable for connecting a variety of external
equipment;
8. No longer limited to a single transmission can only be paired with a single channel, the same transmission can be interused in
400 channels of two channels, showing the humanized high-tech design;
10. Metal aluminum hand-held tube;
11. The power consumption of the microphone is 80mA, powered by 1.5V battery (2 capsules), which can be used continuously for 12
hours;
12. The host and transmitter are equipped with LCD screen to display the working state and other contents
13. Use distance: open environment: 150-300 meters complex environment: 80-150 meters
14. Suitable for meetings and speeches.
