The PAL rear panel has a 3.5mm auxiliary input to connect a CD, MP3 player, or other device, plus a 3.5mm stereo headphone output for private listening (headphones not included). It could also be used as a recording output, or to use the PAL as a high-quality outboard tuner. There is also a coaxial 12VDC 500 ma [+] input jack for the included AC wall adapter. Each jack is covered with a weather-resistant hinged cap.
The FM telescopic whip antenna folds neatly into a recess.
