Signstek FM Transmitter with Antenna


An absolute must for all residential light shows!

Simply plug into your Speaker Output on your PC (xSchedule users) or Speaker Output on your Raspberry Pi (FPP users) to broadcast your audio to a tunable FM radio station. Please note, many “on-board” computer speaker outputs can often introduce unwanted noise, and is highly recommended to utilize a standalone soundcard like the USB Creative Labs Sound Blaster Play! 3 to process your audio files.

Additionally, it is recommended to process your audio files using free Audacity software to pull-down lower band “bass” frequencies, which can sound distorted during transmission (Effect>Graphic EQ). MP3Gain software is also recommended to normalize your library of audio files to a specified peak (96-97 dB) to remove clipping and create consistency throughout your show, without re-compressing the audio file.
