How to get your music
Connect your Android or iPhone to the KD-R670's front-panel USB input, and you can control your music and charge your phone. iPhone users can even control and enjoy the playlists they've created on Pandora® and iHeartRadio®. The USB port also enables you to connect a flash drive filled with MP3, WMA, WAV, and FLAC music files for hours of listening pleasure. The front auxiliary input provides a connection. Pop in a CD or tune in your favorite local AM and FM stations.
Setting up your audio and display
A built-in 3-band parametric equalizer, twelve EQ preset settings, and loudness controls let you zero in on just the right sound. JVC included two sets of preamp outputs, so you can plug in an amplifier or powered subwoofer to your music. The KD-R670 receiver also features built-in dimmer and brightness controls, so you can see the info on its single-line display.
