Two-in-one Wireless Conference Microphone (Short Rod) UK-Ai220HL

Product Features:

1. Adopts UHF ultra-high frequency band, featuring less interference and more reliable transmission compared with traditional VHF bands. It supports two-channel signal reception with 100 selectable channels per channel and IR infrared automatic frequency matching function, suitable for various conferences and speech scenarios.

2. Each channel is equipped with independent electronic volume adjustment with 31 volume levels. Signals are transmitted over the UHF band in 250KHz steps, and frequency matching is realized via infrared.

3. Supports screen lock function operated through function group keys. Audio and data adopt dedicated pilot signals and ID codes to effectively prevent crosstalk and interference.

4. Comes with one-touch frequency scanning function for intelligent search of interference-free frequencies. Each channel features antenna diversity function that automatically indicates the current antenna status for stronger anti-interference capability.

5. Transmits signals over the UHF band within the frequency range of 640-690MHz. The LCD screen displays working channel, operating frequency point, received signal and audio signal.

6. Two rubber receiving antennas are installed on the rear of the receiver to strengthen signal reception with an elegant appearance.

▲7. The rear panel is equipped with 2 balanced outputs, 1 mixed unbalanced output and 1 mixed balanced output, compatible with various external devices.

▲8. Built-in AI voice control: supports control of power supply, lighting, LED screen power, video switching, volume and conference status indicator at the entrance, with voice feedback.

▲9. Supports voice control via short gooseneck microphones and external omnidirectional microphones, mis-touch wake-up prevention, and 1 monitoring output.

▲10. Equipped with 1 power sequencer control port, 1 lighting control port, 1 conference indicator control port, 1 LED screen control port, 2 RS-232 ports for volume control and video switching, 1 set of voice feedback monitoring and 1 line input. Wake-up word example: Conference Assistant. Feedback announcement: I’m here, please speak. When increasing volume, the volume rises in 1dB steps.

▲12. Built-in 3W cavity speaker, whose power-on and power-off can be controlled by voice.

13. Supports synchronous display of frequency and channel. Both receiver and transmitter display battery status. Low battery reminder is available, and audio will be muted when power runs out to avoid noise caused by power failure during use.

14. Microphone power consumption: 80mA. Powered by 2 pieces of 1.5V batteries for continuous operation of more than 6 hours.

15. Operating distance: 60 meters
