※ FEATURES OF THE PRODUCTS

1. UHF (Ultra High Frequency) range and advanced DPF (Digital Pilot Frequency) technique

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 dozens 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. Unique "receiver’s sensitivity-adjusting function" allows its sensitivity to be adjusted according to actual needs to increase either the capacity to resist disturbance or
the receivable distance.
6. Max. working distance between the transmitter and the receiver can reach 200 meter.
7. Function of ASF (Automatic Searching non-interference Frequency) points.Easy and quick.
8. Pressing the “Lock” button or pressing the two SET buttons simultaneously can lock the frequency and avoid misoperation in working.
9. Coded lock allows presetting and limiting total times of the product to be turned on.
10. Electronic volume control: 0-39 stages adjustable with 2dBm adjusted by each stage.
11. The interface between USB and earphone using serial communication can control the songs-selecting-device and the central control unit, and can follow up pictures in videoing.
12. “One button to install” function can build-in 100 group of installing frequency points to facilitate dozens sets of the product to be used to set their frequency points simultaneously.
13. There are 4 preset equilibrium modes: (1) straight flat, (2) bass increased,
(3) high pitch cut, (4) bass increased and high pitch cut.
14. The total-view LCD display screens show clearly from any angle working status
of the transmitter and the receiver.
15. 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.
16. Gold-plated copper AF interfaces of receiver and the matched 6.35 AF cables can
ensure perfect transmittion of audio frequency signals.
17. 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.
18. Advanced CPU and exclusive designed software are used to make the whole system
run accurately, efficiently and professionally.
19.All the receiver panels are carefully designed, reasonably arranged and easy to operate.
20.Hands of the speaker can be free while he or she is speaking when the collar-clip microphone is used providing more flexible and practical options to users.
21. Automatic "Low Battery" warning is built-in the mini-transmitter's display to provide convenience to users.
22. Steel case of the receiver, adopting standard 1U case design and spraying painted wearproof water-wave finishing, looks very nice and is strong, durable to use.
23.Years of experience, professional design, quality materials and components, plus meticulous manufacturing process, create together the excellent product w/ high quality, outstanding performance and pretty appearance.
