Overview

Pioneer’s DEH-4250SD CD tuner goes a step further towards offering endless music connectivity in the car. The media options on Pioneer’s DEH-4250SD CD tuner are truly impressive with a SD card slot, front USB and Aux-in connection, iPod Direct Control and 3 RCA Pre-outs.

No longer just a CD tuner, but rather a travelling jukebox, the DEH-4250SD plays audio from an SD card, portable USB device, MP3 player and even your iPod or iPhone. Of course, it also plays the traditional CD. 

Key Features

SD Card Playback
Take your entire music collection on the road using just one SD card. With an SD card slot discreetly hidden behind the front panel, the DEH-4250SD is compatible with both SD and SDHC cards and will playback MP3, WMA, WAV and AAC files from these cards. Filled with your favourite tunes, the SD card is becomes your musical HDD when inserted into the DEH-425SD. Unlike most products with a HDD, the SD card can be removed at any time.

iPod / iPhone
The DEH-4250SD is designed as the most dynamic solution to connect and improve playback performance for an iPod and iPhone. With iPod Direct Control, consumers can connect their iPod straight to the tuner’s front USB terminal and take charge of their music from behind the wheel.As a handy extra, the iPod/iPhone will charge while connected.

Front USB Connection
Take your favourite MP3 and WMA files for a ride. The DEH-4250SD has a front high-speed 2.0 USB (direct) interface to connect a portable digital player, such as an iPod or iPhone, as well as a USB memory device or other USB-compatible gear, so you can play in your car whatever you have recorded via PC. It's fast and easy. No adapters required.

Front Aux-In Connection
The music connectivity extends beyond USB. Hook up your portable digital devices with ease. 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.

5x7 dot OEL display
To make searching and selecting tracks from various sources more convenient, the DEH-4250SD comes with a 5x7-dot Blue OEL display. OEL technology allows for wide viewing angles, active 3D visuals and high contrast and brightness, even in sunlight.

24-bit Delta Sigma D/A converter
High powered, serious audio performance is not forgotten, either. The unit integrates a 24-bit Delta Sigma D/A converter along with our ASR (Advanced Sound Retriever) technology, which ensures that what you hear is optimised to replay as true to the original as possible.

Advanced Sound Retriever
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.

Built in 50W x 4 Channel High-Power MOSFET Amplifier
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.

High Pass Filter / Low Pass Filter Crossover
The unit ensures subwoofer control is very convenient with an on-board low pass and high pass filter. When the subwoofer is connected and you do not want low sound to play from the front or rear speakers, turn the high pass filter on. Only frequencies higher than those in the selected range will be outpu
