Attention.1, this transmitter does not support the insertion of a microphone, so that the microphone is not working.2, the transmitting antenna as far away from the transmitter as possible, because the antenna will transmit high frequency strong signal to the nearby space, if the antenna is too close to thetransmitter, it will interfere with the audio input line, you will hear the buzzing interference on this side of the radio. It is best to use 2-3 meterslong 50 ohm coaxial cable to connect the antenna to the transmitter to reduce the interference to the front end. If you need to use a soft antenna
It is recommended to set the output power to a smaller state to reduce the impact on the audio channel.
Output frequency: 76-108MHz, 100KHz step, total 320 transmitting frequencies, with memory function.
Output power: 10~500mW
(0.01~0.5W) @88-108MHz.
The output power can be set from 10mW to 50mW by pressing the key, total 11 steps, the power setting is automatically memorized, and the next power on will be output according to the previous setting. (
Output power can not be used as a power reference)
Receiving equipment: ordinary radio, FM radio can receive good reception of this transmitter emitted by the
signal.
Display: LCD display, the display content is the current transmission frequency, see the manual, with FM transmitting antenna production data
The actual measurement of this transmitter in the open space can reach a maximum distance of 2000 meters.
Power supply voltage: 5V USB-type-C
Power supply current: 500mA
Input signal: audio stereo, 3.5mm interface standard, input volume should be appropriate, evaluation area has a friend input too large obviously distortion, to reduce the volume of the
Apparent distortion, to reduce the volume, to the final effect of general FM radio quality shall prevail.
Note: This transmitter does not support microphone input!
