Hear the glory of original sound across a deeper, wider spectrum from highly compressed MP3 and WMA files stored on a USB memory device. By compensating for data (especially higher frequencies) that tend to get lost in the digital compression process, Pioneer's Advanced Sound Retriever technology enhances audio reproduction nearly all the way up to 20kHz frequencies.

To minimize voltage loss in its head unit amplifiers, Pioneer built-in high-performance Power MOSFET integrated circuitry into all its head units. The MOSFET amplifier processes signals more efficiently at 50W x 4 maximum total output. This reduces distortion to virtually nothing at high frequency ranges giving you great clear sound.

Front Aux-In Connection
Hook up your portable digital devices with ease in an instant. Each new Pioneer head unit has a built-in AUX input on the front panel so you can connect your iPod, MP3 player and other portable music devices.
