True diversity automatically selects signals, eliminates receiving blind spots, avoids signal interruption, infrared frequency matching technology
Phase-locked loop frequency synthesis technology, 38KHz pilot frequency technology, large sound dynamic range, high sound reproduction, low power consumption
The scope of application of this system: professional KTV, large and small stages, dance halls, conference halls, teaching lectures, home entertainment
UHF 800MHz frequency band, phase-locked loop (PLL) frequency synthesis
Superheterodyne secondary frequency conversion design, with extremely high receiving sensitivity
Using multi-level high-performance SAW filters, with excellent anti-interference ability
It is produced with highly reliable SMD components and passed the 8-hour aging test before leaving the factory.
The microphone uses Tesco's AA battery, which lasts for 10 to 30 hours
The microphone uses a dual boost design, the battery power drop does not affect the transmission power
