PA1418FV
STEREO FM TRANSMITTER
Functions
The PA1418 FV new stereo FM Chip is capable of
broadcasting good quality signals over a range of about 60
feet. It's ideal for broadcasting music from a CD player or from
any other source so that it can be picked up in another
location.
For example, if you don't have a MP3/CD player in your car,
you can use the PA1418 FV to broadcast signals from the
portable MP3/CD player to your car's radio. Alternatively, you
might want to use the PA1418 FV to broadcast signals from
your lounge-room DVD/CD player to an FM receiver located in
another part of the house or by the pool. It can be used for
transmitting surround sound.
It broadcasts on the FM band (i.e., 88-108MHz) so that its
signal can be received on any standard FM tuner or portable
radio.
