A.Product Introduction
Advantages
To assure the best performance,please read this manual carefully
and keep the manual in a cafe place for future reference.
UHF multi channel wireless system is a intelligent multi functional
wireless system, adopts UHF multi frequencies design, PLL technology,
ultra high frequency wireless transportation, with stable quality, long
working distance, clear sound quality, wide and clear LCD display and
fashionable outlook design.
conference rooms and teaching rooms.
It adopts UHF (Ultra High Frequency) band transportation, with
frequency range for 610-960MHz.Frequencies can be designed
according to the regulations of the country in which they are actu-
ally used, so as to be suitable for various countries and regions.
Micro-computer CPU Controlled
The hardware circuit of the whole system is controlled by the
CPU of the micro-computer. It can select frequency, display frequ-
ency and process frequency data etc. It can realize various functions
that are not easy to realize in traditional models.
Wide and Clear LCD Display
With high performance, wide and clear LCD display, all operat-
ions can be displayed on the LCD screen to facilitate users to und-
erstand the working status of the system and set up the system.
Display content includes: radio frequency signal strength, audio
signal strength, channel and frequency, ACT working status, etc.
High Precision PLL Technology
Compared with the quartz-controlled system, the PLL technology
with high precision phase-locked loop frequency synthesis has
higher frequency stability and excellent frequency selection char-
acteristics. It can realize multi-channel and multi-functional prof-
essional functions in the system.
Channel Selection
The system is with Channel Selection, and the user can set the working
channel according to the actual needs by very simple and conven-
ient operation.
Audio Output
The Audio output is equipped with XLR balanced output and

Automatic Channel Tracking (ACT)
The system has high-tech automatic channel tracking (ACT)
function. After the receiver has set up the receiving channel, the
transmitter frequency can be locked automatically and accur-
ately by infrared data transmission, so that the transmitting
frequency can be synchronized with the receiver.
Anti-interference Multi Channels Design
The system uses a variety of anti-interference technology. It
has 160 non-interference frequencies as the factory default s-
etting. It is reasonable to design and convenient for users to use
multi-system at the same time. It is an ideal product for speech
and conference rooms.
Battery status indicator/Lower power warning
The battery power of handheld transmitter, bodypack trans-
mitter and conference transmitter can be displayed on their LCD,
and the warning is given when the battery power is low, promptly
reminding users to change batteries to ensure the normal oper-
ation of the system.
1/4 inch unbalanced output, which makes it easy for users to
connect to different external devices.
Modular Mic Capsule Design
The Mic capsule of the handheld transmitter adopts modular
design, which can facilitate users to configure different sound q-
uality Mic capsules to adapt to different occasions.

（single LCD models）, press A, B, C, D button to switch to the relevant
channel, and press “▲”or“▼”button to choose the suitable frequ-
ency and press “SET” button to confirm the frequency.
(2 and 4 LCD models), Press “▲”or“▼”button according to LCD
of the relevant channel to choose suitable frequency, and press “SET”
button to confirm the frequency.
IR Synchronization for the transmitters (figure 6)
Turn on the power of the transmitter
Open the batter holder of the transmitter to expose the IR port, and put
the IR port towards to IR window of the receiver, press A, B, C, D button
to switch to relevant channel, and press “SET” button to synchronize
the frequency.
When there is RF sigal appear, the system is working normally.

E.Tips for improving system performance
① CHANNEL: display current working channel
② BATT: Display the Remaining Electricity of Transmitter Battery. When the batt-
ery power is low, the sign flashes. The battery should be replaced immediately to
ensure the normal operation of the transmitter.
① FREQ: display current working frequency
② CHANNEL: display current working channel
③ BATT: Display the Remaining Electricity of Transmitter Battery. When the batt-
ery power is low, the sign flashes. The battery should be replaced immediately to
ensure the normal operation of the transmitter.
Transmitter can synchronize the working frequency automatically.
Please check the guidance above for the IR synchronization for the
transmitters from the single system setting.
*l The transmitter and antenna should be kept in an accessible linear
relative position.
*l Do not place the receiver close to the metal surface or close to any
digital device (such as CD player, computer, etc.).
*l The receiver should be protected above 1M from the ground and not
close to the wall as far as possible.
*l Transmitting devices such as cellular phones and bidirectional radios
interfere with audio transmission. Transmitters and receivers should
be kept away from these devices and other potential sources of inter-
ference.
