Specifications

Operation
1. Please choose non-intermodulation frequency setting. Usually 4 transmitters can be used
at the same time within 25MHz bandwidth. If more sets of wireless microphones are needed,
devices with other frequency band should be applied.
2. There should be appropriate distance between the receiver and transmitter. Transmitter
should be not too far and too near to the receivers.
3. If receiving condition seems not to be as good as expected, extended cord, exterior high-
gain antenna, and even antenna amplifier can be applied.
4. The receiver and transmitter must be set at the same frequency channel.
5. When several sets of receivers are used together, it is recommended to use high-gain
antenna, antenna amplifier and receive branch unit.
6. Barrier between transmitter and receiver should be as small as possible. The best situation
is when signal from transmitter can reach receiver directly.
7. When Receiver adopts the omni-directional antenna, please keep the antenna away from
the wall, and also away from any other metal objects.
8. The transmitters should by at least 20 cm apart when multiple transmitters are used
together. It prevents interfere to each other.
9. If the transmitters are set in small power mode, you can use 100 transmitters at the same
frequency band.
11. When you use Handheld Microphone, please hold it in the middle of the microphone
body. If you hold too close to the Micro phone grille, it will affect the sound pick-up; if too
close to the antenna (at the bottom of the microphone), transmission efficiency and working
distance may be reduced.
12. When system is not in application for a long period of time, please turn off the device and
take off the battery.
