※ FEATURES OF THE PRODUCTS

1.UHF (Ultra High Frequency) range and advanced “twin reception, DPF (Digital Pilot Frequency) technique” are adopted with less disturbances and more reliable transmission

of signals than traditional VHF (Very High Frequency) range.
2. Advanced circuit of Liwmik TDR (True Diversity Receivers) adopts two antennas
connecting to their respcetive tuners. The output signals from the demodulators are sent
to the comparator. Its output signal is switched to the better-quality-signal at all times.
(as shown by the pictures)
Benefit: the tech upgrades the quality of signal output significantly to ensure it's free from signal-dropout and noise-interference under any normal circumstances though the cost is higher. It's especially suitable to professional stage, live performances and VIP speech
to ensure perfect sound quality.
3.The advanced 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.
4. Advanced AIFS (Automatic Infrared Frequency-Synchronizing) technique is adopted.
Even frequencies of the transmitter and the receiver are adjusted to be untuned, just
pressing on the “Sync” button will allow the transmitter to track frequency of the receiver
and adjust their frequencies to be the same automatically. Easy to use.
5.Unique high/low power switching function allows either high-power transmission in
large shows (which area over 1000㎡), or low-power transmission in small shows
to save power of batteries.
6.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.

7.Max. working distance between the transmitter and the receiver can reach 300 meter.

8.Function of ASF (Automatic Searching non-interference Frequency) points.

Easy and quick.
9.Pressing the “Lock” button or pressing the two SET buttons simultaneously can lock
the frequency and avoid misoperation in working.
10.Coded lock allows presetting and limiting total times of the product to be turned on.
11.Electronic volume control: 0-39 stages adjustable with 2dBm adjusted by each stage.
12.The receiver tracks and shows real-time working power of the transmitter to avoid
its sudden outage of power in working.
13.The high-end total-view high definition LCD display screen can show clearly real-time detailed working data of the system from any angle, including working frequency, AF/RF signals intensity, sound volume, power of transmitter battery, status of lock/unlock, and Infrared signal, etc.
14.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.
15. Gold-plated copper AF interfaces of receiver and the matched 6.35 AF cables can
ensure perfect transmittion of audio frequency signals.
16.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.
17. The small receiver box is easy to carry, move or install.
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 1/2U 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.
