Product Features:
Adopts the UHF ultra-high frequency band, which features less interference and more reliable transmission compared with the traditional VHF band. It supports dual-channel signal reception, with 100 channels available for each channel, and is equipped with IR infrared automatic frequency matching function; suitable for various conference and speech occasions.
Each channel is equipped with independent electronic volume control, featuring 31-level electronic volume adjustment per channel. Signals are transmitted in the UHF band with a 250 kHz frequency step, and frequency matching is realized via infrared technology.
Equipped with a screen lock function operated through function key combinations. Audio and data transmission adopts dedicated pilot signals and ID codes, effectively preventing crosstalk and interference.
Features a one-click frequency search function to intelligently locate interference-free frequencies. Each channel is equipped with antenna diversity, which automatically indicates the current antenna status for enhanced anti-interference performance.
Signal transmission in the UHF band with a frequency range of 640–690 MHz. The LCD screen displays the working channel, working frequency point, received signal, and audio signal.
Two rubber receiving antennas are installed on the back of the receiver to enhance signal reception, with an elegant and decent appearance.
▲7. Equipped with 2 balanced outputs, 1 mixed unbalanced output, and 1 mixed balanced output on the back, suitable for connecting various external devices.
▲8. Built-in AI voice control: supports control of power supply, lighting, LED screen power, video switching, volume, and conference status light signs at the entrance, with voice feedback.
▲9. Supports voice control for gooseneck microphones and external omnidirectional microphones, features anti-misoperation wake-up, and provides 1 channel of monitor output.
▲10. Built-in 1 power sequencer control port, 1 lighting control port, 1 conference light sign control port, 1 LED screen control port, 2 RS-232 ports for volume and video switching control, 1 group of voice feedback monitoring, and 1 line input. Wake word example: Conference Assistant; voice feedback example: Yes, please speak. Volume increases by 1 dB step when the 'turn up the volume' command is received.
▲11. Supports AI voice one-click shutdown of all devices with an application sequence protection mechanism: conference system shuts down first, display screen shuts down after 5 seconds, and lighting shuts down after 10 seconds to prevent switch damage caused by impulse current.
▲12. Built-in 3W cavity speaker, supporting voice control for turning on and off.
Simultaneous display of frequency and channel. Both the receiver and transmitter show battery status, with low battery reminders for battery replacement and automatic muting when power is exhausted, effectively avoiding noise caused by power depletion during use.
