Switchable US and Europe Tuner Frequencies
If you happen to take the 754DI outside of the US, you are able to pick up European frequencies so that you can enjoy your music abroad as well.
Radio Data System allows FM broadcasters to send more than just an analog audio signal over the air waves. Using a 57 kHz "subcarrier," stations can transmit digital RDS data for reception by RDS-equipped FM tuners. Depending on what the broadcaster transmits and what your tuner can pick up, you can receive information such as the name of the artist/song, name of the station, genre, traffic information, and more.
Front Auxiliary In
On the front of the 754DI is an input labeled “AUX”, which allows the input of audio signals for MP3 players, headphones, and portable music players.
Output Power: 80 Watts x 4 Channels
The 754DI offers four channels that can be used to hook up four speakers. Typically though, it is a much better practice to have an amplifier running your system.
