How we picked the best FM transmitter
What is an FM Transmitter?
An FM Transmitter is a device that is designed to accept an audio signal from the source device such as MP3 players or microphones and then broadcasts the same as an FM signal. This signal can be detected by any nearby FM receiver. This could be the FM radio in your car or a portable FM radio. This forms a simple yet effective wireless means of communication.
Picking an FM transmitter in the market may be challenging with many options available and with different feature sets and at different price points.
In our research, we considered the following main attributes
Transmission range: An important specification that will determine whether you will be able to reach the audience within a certain geographical perimeter – a larger transmission range is required to cover a larger area.
Signal quality: The electronic design of the product and quality of components used in the design determine how clear the received signal is. Poor quality electronics will result in poor signal quality.
Regulations and policies: The FM band is used to transmit radio signals. FCC compliance ensures that your equipment operates in harmony with other licensed transmissions.
Other very important considerations we factored into our recommendations are Price, Portability and Ease of use.
Common Problems and Solutions
Users have reported a couple of problems with the FM Transmitter. Fortunately there are solutions to both.
Humming Noise Problem
Users have complained about an annoying Humming noise during operation. Here are potential solutions for each:
- The supplied power supply is a two prong supply without a ground. This produces a hum associated with the 60 Hz frequency. To eliminate the hum, replace the supply with a 3 prong 12 VDC power supply.
- The hum could also be used to the audio and input level settings. The audio volume knob should be adjusted carefully. If there is noise, static or over driven audio, then turn down the input level. However, if the input level is too low then you might hear a hum. So you will need to play with the level to get it right. This unit sounds very good when it is set up properly with optimal settings.
Noisy Fan Problem
This unit has three power amplifiers to generate up to 7 Watt of transmit power. That’s a lot of power in very small product dimensions. The associated analog circuits are going to generate heat during operation – there is no way around that. A fan has been included in the product to dissipate some of this heat. However, fans are finicky mechanical devices. They can be noisy if not designed and/or installed properly. And that happens to be the case with this transmitter. To limit the possibility of the fan turning on, it is recommended to operate the transmitter in low power mode.
The Future of FM transmitters
FM Transmitters have been used for many decades, and the use of such devices is expected to increase in the coming years as many people prefer going cordless. Even without the current pandemic and social distancing, there is an increasing shift toward wireless in organizations and institutions. People also now view them as ideal for outdoor events such as drive-in movies, church functions, concerts and speaking events.
FM Transmitters are devices for wireless broadcasting of audio signals that can then be received by any FM receiver that is tuned at the same transmission frequency. These devices are ideal for many live functions and operations in institutions and organizations such as schools, parking lots, live concerts, supermarkets, church drive-in, etc.
