Characteristic explanation：

• Uses the UHF700-870MHz frequency band, avoids the interfering frequency
• Uses the multistage narrow bands high frequency and the intermediate frequency chooses the frequency filter, full interference elimination signal
• Hand-hold microphone stealth antenna, artistic practical
• Grasps the microphone to have the electric quantity indicating circuit, prompts the replacement battery
• Uses the quartz oscillating circuit completely, has the extremely high frequency fixing performance
• Uses the audio frequency compression - expansion technology, the noise big reduction, the dynamirange enlarges
• Is equipped with the feedback to whistle by pulls down weakens the function, can reduce the feedback to whistle by effectively
• The receiver uses the multistage high-frequency amplifications, has the extremely high sensitivity
• The multiple noise monitoring electric circuit, enables it to have the greatly strengthened antijamming characteristic
• Has the perfect switch static wipe circuit, avoids when opens the switch, has the giant pulse static
• Selects the extremely good chip, causes this aircraft acoustic fidelity to be extremely splendid
• Selects the high quality spare part, the precise reasonable circuit design, the reliability enhances greatly
• Open biggest service range 100 meters, open ideal service range 60 meters
• Is suitable in size places and so on song ballroom, assembly hall, teaching teaching, Kara OK hall, family entertainment
