UHF (Ultra High Frequency) range and precise technique of APF (Analog Pilot Frequency)are adopted with less disturbances and more reliable transmission of signals than traditional VHF (Very High Frequency) range. 2. The DPLL (Digital Phase Lock Loop) multi-channel frequency composing technique can provide as much as 200 channels by 300KHz spacings within 60MHz frequency bandwidth facilitating several sets of the product being used at the same time to avoid easily various disturbances. 3. AIFS (Automatic Infrared Frequency-Synchronizing) technique is adopted. Even frequencies of the transmitter and the receiver are adjusted to be untuned, just one pressing on the button will allow the transmitter to track frequency of the receiver and adjust their frequencies to be the same automatically. Easy to use. 4. Max. working distance between the transmitter and the receiver can reach 100 meter. 5. Plug-to-use receiver, convenient to use. 6. Wide audio response frequency range of the product covers the frequency range of sound waves that can be heard by human ears. Whether it is deep bass, melodious mediant , or loud and clear treble, all voice can be perfectly transmitted and reproduced to ensure the Hi-Fi sound effect.7. Automatic "Low Battery" warnings are built-in the mini-receivers and handhelds to provide convenience to users.8. Years of experience, professional design, quality materials and components, plus meticulous manufacturing process, create together the excellent product w/ high quality and pretty appearance.
