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. Signals are transmitted in the UHF band with a 250 kHz frequency step, and frequency matching is realized via infrared technology.
Equipped with a lock screen function operated through function combination keys. 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 and delivers stronger anti-interference performance.
Transmits signals 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 rear of the receiver to enhance signal reception, with an elegant and decent appearance.
The rear panel is equipped with 2 balanced outputs, 1 mixed unbalanced output, and 1 mixed balanced output, suitable for connecting various external devices.
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.
Supports voice control via head-mounted microphones and external omnidirectional microphones, features anti-misoperation wake-up, and supports 1 channel of monitor output.
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 channels for volume and video switching control, 1 group of voice feedback monitoring, and 1 line input. Wake word: Conference Secretary; response prompt: Yes, please speak. Increasing the volume raises it step by step at +1 dB.
Supports one-click AI voice shutdown of all devices with an application sequence protection mechanism: the conference system is turned off first, the display screen is shut down after 5 seconds, and the lighting is turned off after 10 seconds to prevent switch damage caused by impulse current.
Built-in 3W cavity speaker, supporting voice control for turning on and off.
Displays synchronized frequency and channel information. Both the receiver and transmitter feature battery status indication, with low battery reminders and mute function when power is exhausted, effectively avoiding noise caused by power depletion during use.
The microphone consumes 80 mA, powered by two 1.5 V batteries, supporting over 6 hours of continuous use.
