FM transmitters FAQ

Q1.How can I install the FM Transmitter

A: 1. Install the antenna;

2. Link the cable to the antenna;

3. Link the 50 Ohm Coax cable to the “ANT” –(BNC Type)Be sure the link is stable;

4. Link the audio input to the “Audio” –3.5MM Stereo socket;  

5. Link the DC POWER module to the “POWER”–6.5mm POWER socket ( DC 12V(current >2A) Pay Attention to the power polar : inside positive; outside negative);  

6. After electrified,the frequency is the one of last power off; 

7. Frequency Increase Control ,pull the button“UP”,every pull can increase 100KHz,pull the button for more than 1 second,the stepping jump to 1MHz;

8. Frequency Decrease Control,pull the button“DOWN”,every pull can decrease 100KHz,pull the button for more than 1 second,the stepping jump to 1MHz.

Q2.How far it work

A:Transmitting power, the use of the environment, Transmitting distance relationship.

Q:how many kilometers will the 500mW transmitter transmit?

A:The 500mW transmitter can transmit 0.1->1 kilometers due to the area(city town or village is different) and the antenna you use!

Q:how many kilometers will the 5W transmitter transmit?

A:The 5W transmitter can transmit 1->5 kilometers due to the area(city town or village is different) and the antenna you use!

Q:how many kilometers will the 15W transmitter transmit?

A:The 15W transmitter can transmit 5->10 kilometers due to the area(city town or village is different) and the antenna you use!

Q:Are the transmitters stereo and PLL?

A:All the transmitters we sell are stereo and PLL!

Q:The frequency of FM transmitter?

A:All FM transmitters are 88-108MHZ continuously tunable.

Q:Would I require a cooling fan for continuous transmit? Could the power be increased with larger heat sink and cooling fan?

A:OK,You can try it with a cooling fan and high voltage(not more than 13.8V)

Q:Will Leaving My FM Transmitter On All Day & Night Harm It?

A:No, The FM Transmitter is designed to run non-stop 24 -7.

Q:Why Doesn't My FM Transmitter Turn On?

A:• Is the power cord firmly attached to the FM transmitter?
• Is the AC adapter plugged into the wall?
• Make sure the audio cable is firmly plugged into both devices.
• make sure the volume is not all the way down.
• Make sure your audio device is working.

Q:Why Don't I Hear Anything?

A:• Is the audio cable firmly attached to the  FM Transmitter  and your audio source?
• Is the volume turned up on your audio source?
• Is the volume turned up on your FM Receiver source?
• Make sure the audio cable is firmly plugged into both devices.
• Make sure your audio device is working.

Q:What Is The Cable With The Red & White RCA Jacks For?

A:This is a special custom made cable enabling you to broadcast from devices like DVD & VCR players that do not have an earphone jack but only RCA jacks. You can also use it to broadcast from a home theater or stereo tuner and some satellite radio units.

Q:I Think All Of The FM Frequencies Are Used In My Area?

A:Some people report that all transmitter channels are being used. This is not possible since the FCC requires blank channels between commercial stations. What they are hearing is bleed-over noise from a commercial station. When you select one of these blank channels the FM transmitter will broadcast over the noise.

Q:I Lost My AC Adapter Can I Use Some Other One?

A:Yes, you can use the appropriate +12 V switching power supply. Must pay attention to the polarity of power.

Q:How long will I receive the transmitter after payment?

A:We ship the transitter via DHL/TNT Express, it will take 4-7 business days to get to you!

Q:Will you offer combined shipping?

A:Yes,we offer combined shipping,you can save shipping cost if you buy more transmitter!
