UHF Microphone System

Product Introduction

To assure the best performance,please read this manual carefully and keep the manual in a cafe place for future reference.
A.Product Introduction 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. This system is suitable for professional stage, multi function hall,
conference rooms and teaching rooms. 1 Advantages
UHF Frequency Transmission
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 actually 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 frequency 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 understand 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 characteristics. It can realize multi- channel and multi-functional professional 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 convenient operation.
Audio Output The Audio output is equipped with XLR balanced output and

Technical Parameters

1/4 inch unbalanced output, which makes it easy for users to connect to different external devices. 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 accurately 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 setting. 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 operation of the system.
Modular Mic Capsule Design
The Mic capsule of the handheld transmitter adopts modular design, which can facilitate users to configure different sound quality Mic capsules to adapt to different occasions.

E.Tips for improving system performance
lThe transmitter and antenna should be kept in an accessible linear relative position.
lDo not place the receiver close to the metal surface or close to any digital device (such as CD player, computer, etc.).
lThe receiver should be protected above 1M from the ground and not close to the wall as far as possible.
lTransmitting 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 interference.

Troubleshooting

G.Troubleshooting Problem
No operation indication
No RF signal

Possible cause
Transmitter’s batteries are exhaustedor DC in is not connected well. Transmitter and receiver are not at the same channel Transmitter is out of range
Transmitter is muted(“MUTE”)

RF signal available, no audio signal,”Mute” appears on the display panel

Receiver’s squelch threshold is adjusted too hight Transmitter doesn’t transmit a pilot tone

Audio signal has a high level of background noise Audio signal is distrorted

Transmitter sensitivity is adjusted too low
Receiver’s AF output level is adjusted too low Transmitter sensitivity is adjusted too high
Receiver’s AF output level is adjusted too high Transmitter set at a low-power

The use of short distance,Signal instrbiity

Squelch is too high Receiver antenna set improper Surrounded by strong electromagnetic interference
