Product Answer:
Q:What is this thing for?
A:This is an FM transmitter. It can be seen as an FM small radio station that inputs audio signals and outputs FM high frequency signals that are transmitted into the air through an antenna. People in the distance around them receive it via radio.

Q: Is this a stereo transmitter?
A: Yes, this is a stereo transmitter. Q: Is there a battery inside the transmitter? A: The transmitter does not have internal batteries and requires an external power supply.
A: Yes, this is a stereo transmitter. Q: Is there a battery inside the transmitter? A: The transmitter does not have internal batteries and requires an external power supply.
Q: How is the transmitter powered?
A:The transmitter is powered by 5V DC and the power supply interface is USB Type C. The current consumption is about 20OmA. The current consumption is about 20OmA, if you use poor quality power supply, it may cause the transmitter can not work properly or the transmission quality will be degraded, the radio terminal will receive obvious noise. The power supply voltage requirement is 4.8-5.5V, out of this range will cause the transmitter to work abnormally or even damaged, please note!

Q:Can I use a microphone as a transmitter?
A:The transmitter cannot be plugged directly into a microphone. If a microphone amplifier is used, the amplified microphone signal can be input to the transmitter.

Q:Is it possible to attach a dummy load to the antenna port of the transmitter instead of the antenna?
A:No. A dummy load is a pure resistor that absorbs the signal from the transmitter output and the transmitter will have no energy to emit into the air. By connecting a dummy load to this transmitter and relying only on the weak power leaking out, the radio will be able to pick up the transmitter's signal within a meter or two at most. The dummy load and the antenna are two devices with opposite functions and are irreplaceable.

Q:How to set the transmission frequency?
A:The transmission frequency can be adjusted by the two buttons on the panel, you can choose step to let the frequency change step by step with 1MHz or 0.1MHz, stop pressing the button for 5 seconds, the transmitter automatically remembers the current set frequency, and next time it starts up, it will automatically transmit at that frequency, no need to set the frequency again.

Q: How to adjust the transmission power?
A:Long press UP button to enter power setting mode, press DOWN/ UP button to set transmit power. The transmit power can be set between 10mW~500mW. There are 11 power levels in total. The button stops for 3 seconds, automatically switches to frequency adjustment mode and saves the current transmitting power, the next power up automatically remembers the last transmitting power and frequency.

Q:Can it really transmit 2000 meters?
A:The transmission distance is directly related to the transmission power, propagation conditions and antenna performance. The claimed transmission distance of 2000 meters is realized under the conditions of 500mW transmission power, antenna set up on 14th floor and no obstruction between transmission and reception. The antenna has been rigorously adjusted by an antenna analyzer to have a standing wave of 1.2 at the transmission frequency.

Q: Can I connect a tie rod antenna directly to the transmitter?
A:Yes, but be careful to judge a phenomenon: if you hear beeping or buzzing on the radio after using the tie rod antenna, it means that it has been interfered. In this case, this phenomenon can be reduced or avoided by reducing the transmitted power. If this interference is always present, then the only way to avoid it is to distance the transmitting antenna from the transmitter and the front end sound source. The antenna is a heat sink and when transmitting high power it can cause interference to surrounding electrical equipment, so once you find that your front end is not working with a strong signal, then the only way to keep the antenna away from the transmitter and the front end is to use a feeder. This will effectively avoid interference.

Q:Why +-0.1MHz can receive signal near the receiving frequency point?
A:This is because the signal received by the radio is so strong that it is impossible to keep the radio away from the transmitter at this time.
A:This is because the signal received by the radio is so strong that it is impossible to keep the radio away from the transmitter at this time.
Q:Why does my radio feel interfered and less sensitive when working on other frequencies?
A:The radio is suppressed when there is a super strong transmit signal near the receiving frequency. This is when it is necessary to reduce the transmit power or move the radio away from the transmitter to reduce the level of suppression by a strong station. There are a large number of filters on the front end of high-end radios to enhance this resistance to suppression.

Q: What is the audio input connector for the transmitter?
A: The input is a standard 3.5mm audio interface, and the input volume should be appropriate. Its input volume is too large and the distortion is obvious. It is necessary to reduce the volume so that the final effect reaches the quality of general FM broadcasting. Note:This transmitter does not support microphone input!

Q: What is the antenna interface of the transmitter?
A: The antenna connector of the transmitter is SMA specification, with external thread and internal hole. The corresponding antenna side requires a connector with a female pin.
