The Pioneer DEH-P4100UB is a well-priced, car-audio CD receiver with a 200w (peak) and 4-channel MOSFET amplifier. The fifth of seven Pioneer DEH receivers, the Pioneer DEH-P4100UB is an upgrade from the Pioneer DEH-P3100UB in that it features Pioneer’s revolutionary Organic Electroluminescent (OEL) display with 16-character text. In addition, the DEH-P4100UB offers three (versus two) RCA Hi-Volt pre-outs for front, rear, and sub connections, not to mention a two-way crossover with separate high and low pass settings. The DEH-P4100UB also boasts a CD player that plays CDs, CD-Rs, CD-RWs, and discs loaded with MP3, WMA, and iTunes AAC music files. Plus, the DEH-P4100UB features an easy-to-use 7-way rotary commander control to quickly search through songs, Bluetooth compatibility so that users willing to invest in a CD-BTB200 Bluetooth adapter can connect their cellular phones directly to the unit, and an advanced sound receiver that more accurately plays back compressed MP3/WMA/AAC music files. Lastly, the DEH-P4100UB boasts a traditional AM/FM tuner with SuperTuner III technology for reduced distortion, a front auxiliary port and USB port for connecting various portable devices, an included iPod connection cable, a graphic 7-band (versus 3-band) equalizer, and a wireless remote control. The Pioneer DEH-P4100UB retails for a more expensive $170.00 (versus $150.00) and comes with a 1 year limited warranty.
