Characteristic explanation：

• Uses the VHF200-270MHz 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
• The launcher is equipped with the low pressure indicating circuit, can instruct the battery service condition promptly
• The receiver is equipped with the low pressure autoswitch function, protects the battery not to harm
• The receiver uses the multistage high-frequency amplifications, has the extremely high sensitivity
• The unique pronunciation pressure limits the design, the great volume speech will not present the crack sound
• 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
• Has the perfect switch static wipe circuit, avoids when opens the switch, has the giant pulse static
• The unique noise static chirp function, refuses the exterior disturbance to open this aircraft my sound system
• 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
