Wireless one-to-two conference microphone BK8434T
Key Word ：
Digital Public Broadcasting System
1. True diversity receiver, dual-channel independent selection system. It can minimize the occurrence of dropouts.
2. Dual-channel independent SC frequency automatic search function, which can quickly scan and lock onto the frequency with the least interference in the working environment.
3. Each channel has an independent digital display for channel and frequency, making it clear for users to operate the main unit. The two-color synchronous display shows orange when off and white when on.
4. The main unit features a high-definition full-view angle LCD display, with clear content.
5. The receiver and transmitter synchronize through IR infrared frequency matching technology with one-button code synchronization.
6. Professional performance-level phase-locked circuit, combined with noise locking, static noise control, and digital pilot tone technology. When the transmitter is off, the pilot tone control mutes the AF signal to suppress noise, while also muting the corresponding receiver. This ensures effective isolation from interference signals.
7. The high-definition display indicates RF and AF signal strength, battery status, frequency, frequency group/channel, and other operational statuses.
8. Each channel has 100 frequency groups, with two different frequencies, totaling 200 groups, allowing for the use of more than 5 units in the same venue.
9. CPU bus control, combined with a digital LCD interface display, allows for smooth operation and outstanding performance. Multiple noise monitoring circuits and a special ID verification system provide strong anti-interference capabilities.
10. Feedback howl suppression function effectively reduces feedback howl.
11. The true diversity wireless system is designed specifically for fixed installation use, providing the highest reliability, sound quality, and transmission stability.
12. Preset digital audio equalizer can simulate the sound characteristics of various audio heads.
13. Open area usage range of 150 meters; can be configured with handheld, head-worn, lapel, or conference microphones.
