Product Description
※FEATURES OF THE PRODUCTS
1. 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 250KHz spacings within 50MHz 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. It is easy to use.
4. Unique high/low power switching function allows either fluent using of the product in places like mass rallies (high-power transmission) , or saving power of batteries when it is used in school classes or KTV (Karaoke Television) rooms (low-power transmission).
5. Max. working distance between the transmitter and the receiver can reach 200 meter.
6. Function of ASF (Automatic Searching non-interference Frequency points). Easy and quick.
7. The operating front panel with 4 independent channels can display clearly and conveniently. 8. There are 4 balanced output interfaces for each channel, 1 mixed balanced output interface
and 1 mixed unbalanced output 6.35 interface on the back panel.
9. Function of “locking the frequency” is built in the menu to avoid misoperation in working.
10. Electronic volume control: 0-39 stages adjustable with 2dBm adjusted by each stage.
11. The total-view LCD display screens show clearly from any angle working status of the transmitter and the receiver.
12. High quality , high density shielded cables with 6.35 interface for audio frequency allow signals to be transmitted to the preamplifier or mixer without loss. Thus higher fidelity of sound-transmission can be ensured.

13. Gold-plated copper interfaces of receiver and the matched #6.35 AF cables ensure perfect transmittion of audio frequency signals.
14. 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.
15. Advanced CPU and exclusive designed software are used to make the whole system run accurately, efficiently and professionally.
16. All the receiver panels are carefully designed, reasonably arranged and easy to operate.
