## Summary description

BLOW 74-153 is an FM modulator designed to transmit audio from an external source to a car radio via FM frequencies. It enables connection of devices through an auxiliary input or compatible line-level signals to broadcast over a selectable FM channel. Useful for integrating modern audio players or phones with older car radios, providing hands-free music playback and portable audio streaming while driving.

## Long description

BLOW 74-153 is an FM modulator that transmits audio from an external line-level source to a car radio via FM frequencies. It connects to an auxiliary output or compatible audio source and broadcasts the signal on a selectable FM channel, allowing playback through the vehicle’s existing radio without direct wiring to the head unit. The device is intended for integrating modern audio players, smartphones or portable music devices with older car radios that lack an AUX input or Bluetooth streaming.
Advantages
The FM modulator provides a simple installation and does not require complex modifications to the car audio system. It enables wireless-like audio delivery by broadcasting through FM frequencies, supports line-level signals for stable sound quality, and lets users select an unused FM channel to minimise interference. Its compact form factor fits hidden or accessible locations in the dashboard area and works with a wide range of portable audio sources.
Suitable for
Connecting smartphones or MP3 players to older car radios
Playing audio from portable media players through a factory radio
Temporary integration when replacing or upgrading the head unit is not feasible
Hands-free music playback and streaming from external devices while driving
Key specifications
Transmission method: FM broadcasting to car radio
Input type: auxiliary / line-level audio input compatible with portable players and phones
Frequency selection: selectable FM channel to avoid local radio stations
Power: vehicle-compatible power supply (connects to car power source)
Mounting: compact form factor suitable for concealed or accessible installation
How to use
Connect the audio source to the FM modulator’s auxiliary/line input using an appropriate cable. Power the unit from the vehicle’s power supply according to the manufacturer’s instructions. Tune the car radio to the same FM channel selected on the modulator. Start playback on the connected device and adjust the car radio volume for desired listening level. If interference occurs, switch the modulator to another unused FM channel.
Usage recommendations
For best audio quality, use a direct line-level output from the source device rather than a low-power headphone output when possible, and select an FM frequency with minimal local station overlap. Keep cables away from high-noise electrical components and secure the modulator in a stable location to avoid disconnection during driving.
