Adopts the UHF ultra-high frequency band, which features less interference and more reliable transmission compared to the traditional VHF band. It supports dual-channel signal reception, with 100 selectable channels per channel, and is equipped with IR infrared automatic frequency matching; suitable for various conference and speech occasions.
Each channel has independent electronic volume control, with 31-level electronic volume adjustment per channel. Signals are transmitted in the UHF band with a 250kHz frequency step, and frequency matching is implemented via infrared.
Features a lock screen function operated through function combination keys. Audio and data transmission uses dedicated pilot signals and ID codes, effectively preventing crosstalk and interference.
Equipped with one-click frequency search, enabling intelligent scanning of interference-free frequencies. Each channel features 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 640–690MHz. The LCD screen displays the operating channel, operating 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 entrances, with voice feedback.
Supports voice control via short-rod microphones and external omnidirectional microphones, features anti-misoperation wake-up, and provides 1 channel of monitor output.
Built-in control ports including 1 power sequencer 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. When instructed to increase volume, the volume rises step-by-step at +1dB increments.
Built-in 3W cavity speaker, supporting voice-controlled on/off operation.
Simultaneous display of frequency and channel. Both the receiver and transmitter show battery status, with low-battery reminders and automatic muting when power is exhausted, effectively preventing noise caused by power depletion during use.
The microphone has a power consumption of 80mA, powered by two 1.5V batteries, supporting over 6 hours of continuous operation.
