Features:
True diversity receiver, two-channel independent signal selection system. It can greatly reduce the occurrence of frequency interruption.
The two-channel independent AFS frequency automatic search function can quickly scan and lock the frequency points with less interference in the working environment.
Each channel has an independent digital display channel and frequency, allowing users to understand the host operation at a glance. Two-color synchronous display, red when closed and green when open.
The host has a high-definition, full-viewing 1.77-inch TFT display, and the content is displayed clearly. The high-definition TFT display indicates RF and AF signal strength, battery status, diversity channel indication (A/B), frequency, frequency group/channel and other working status
The receiver and transmitter use IR infrared frequency binding technology to synchronize the code with one click.
Professional performance-level phase lock circuit, combined with noise lock squelch control and digital pilot technology. When the transmitter is turned off, the pilot control mutes the AF signal to suppress noise and simultaneously mutes the corresponding receiver. Ensures effective blocking of interference signals
The frequency of each channel is calculated as 160 groups. The two groups of different frequencies are 320 groups in total. More than 8 stacking machines are used on the same occasion.
CPU bus control, combined with digital LCD interface display, easy operation, outstanding performance, multiple noise monitoring circuits, and a specially designed ID identification code verification system, making it super anti-interference
Feedback howling suppression and weakening function can effectively reduce feedback howling
The true diversity wireless system is specially designed for touring performances and fixed installations, providing the highest reliability, sound quality and transmission stability.
Preset digital audio equalizer, which can simulate the sound quality characteristics of various sound heads
Air expansion range is 150 meters; optional hand microphone, headband, and collar clip
