Crutchfield: How Does Pioneer MIXTRAX Work?
From Pioneer: DEH-P8400BH What's in the box
Our take on the Pioneer DEH-P8400BH by Crutchfield's Ken Nail
Packed with features
Check out the features you'll find on Pioneer's DEH-P8400BH CD receiver — Bluetooth® for hands-free calling and audio streaming, an HD Radio™ tuner for the best in radio sound, and Pioneer's MIXTRAX for DJ-style audio and visual effects. When you add in iPod® controls and a great-looking variable-color display, you're looking at a receiver that'll bring safety, convenience, and superb sound to your car.
Bluetooth for safety and convenience
Pioneer's DEH-P8400BH mutes the music when a call comes in and displays the incoming number or contact name. Just press a button and talk — no fumbling for your phone. The receiver stores your phone book if you like, so outgoing calls are easy too. If you've got music on your phone, use audio streaming to send it to the receiver, with no wires to get tangled up.
HD Radio for unparalleled radio sound
HD Radio's sonic advantages are impressive — FM broadcasts that are near-CD quality, with AM that's as good as what you're used to on FM. And if your local HD Radio station employs multicasting, this Pioneer allows you to tune into multiple channels on the same frequency, so you'll have more entertainment choices. Plus, the iTunes® tagging feature lets your save song info when your iPod's connected, so you can purchase the tracks you like later.
Pioneer for great sound
At the heart of this receiver, the built-in amp delivers plenty of power for strong sound. You'll also find an impressive collection of sound-shaping controls. Pioneer's Easy EQ 5-band equalizer lets you adjust the sound to your car's interior, while the Advanced Sound Retriever reverses the compression process to give you more high-frequency sparkle and musical detail from your digital audio files.
Play your music and streaming sources
The DEH-P8400BH plays all your CDs, including those with MP3 and WMA files burned onto them. Plug your iPod into the USB input, and you can use the Pioneer's controls to run the show. Once connected, the receiver bypasses your iPod's built-in digital-to-analog converter, using its own high-quality DAC to deliver your music files with the highest fidelity possible. When you plug your iPhone® into the USB port, you'll be able to take charge of your Pandora® Internet radio stations from the receiver. And this Pioneer's 1-amp USB port will charge your devices in record time.
Choose colors to match your car and your taste
The bright dot-matrix display displays all system information clearly, and you can adjust the display and control colors of this receiver separately, with thousands of possible combinations on tap. The DEH-P8400BH will blend right in, whatever the color of your car's control surfaces and dials.
Want to keep your car's steering wheel audio controls?
In most vehicles, you can use an adapter to connect your vehicle's steering wheel controls to this Pioneer stereo. Connect a few wires, then program the adapter for your particular car and the Pioneer, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.
Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.
iPhone® 5 Note: You'll need to update this Pioneer receiver to enable Bluetooth control and metadata display for the iPhone 5 or other Apple iOS6 devices. This update requires a laptop with Bluetooth running Windows 7.

Engine Time Alert: This setting allows you to measure the length of time that elapses from when the head unit is turned on and display the amount of elapsed time per set period (15 min., 30 min., or Off). There will also be an audible alarm. This function is handy if you are listening to the radio with the vehicle' ignition is in the accessory position, and the engine off.

The automatic dimmer function only works when the orange/white illumination wire in the wiring harness is connected to the vehicle's headlight circuit.
HD Radio: The Pioneer DEH-P8400BH's built-in HD Radio tuner lets you listen to the radio with the same fidelity as your digital music. HD Radio features high quality audio, FM multi-casting, and data services. With HD Radio, your FM stations offer near CD-quality sound, AM stations provide FM-like sound, and there is crystal-clear reception with no audio distortion. Best of all, HD Radio is 100% subscription free. The unit's tuner also supports analog AM/FM broadcasts.
Note: HD Radio is the system for digital AM and FM broadcasting in the U.S. More than 2,000 radio stations are broadcasting their primary signals in digital HD Radio technology, as a free service. Go to HDRadio.com to check for HD Radio stations in your area.
Multicasting: In addition to conventional broadcasts, with HD Radio broadcasting it is possible to choose from up to 3 multicast programs (HD1 to HD3, and analog). There are also data programs for each program.
RDS: The Radio Data System (RDS) feature displays radio broadcast information such as artist, title, and album when listening to compatible analog or HD AM/FM stations.
iTunes Tagging: It is possible to save the song's information (tag) from a HD Radio or RDS FM broadcasting station to your USB-direct connected iPod/iPhone. The songs will show up in a playlist called "Tagged" in iTunes the next time you sync your iPod/iPhone. Then you can directly buy the songs you want from the iTunes Music Store.
Supertuner IIID: The Supertuner IIID features Feed Forward Control, which avoids multi-path interference. This pre-detection of interference enables quick filter control and results in less distortion. In addition, the Supertuner IIID creates enhanced stereo during multi-path interference, unlike conventional tuners that collapse to mono. Digital processing reduces distortion, and improves Signal-to-Noise Ratio and stereo separation. Advanced analog technology improves signal processing sensitivity.
Reception Blending: If a digital broadcast reception condition gets poor, this unit automatically switches to the analog broadcast of the same frequency level. If this function is set to "On", the tuner switches between digital broadcast and analog broadcast automatically. If this function is 'Off', reception will be conducted within an analog broadcast.
BSM (Best Stations Memory): The BSM (Best Stations Memory) function lets you automatically store the six strongest analog or HD stations under preset buttons 1-6 of the currently tuned band. The tuner has 3 FM banks and 1 AM bank. You can store 6 presets for each bank giving you a total of 18 FM presets and 6 AM presets.
Local Tuning: Local seek tuning lets you tune in only those radio stations with sufficiently strong signals for good reception. There are 4 level of sensitivity for FM and two levels for AM. The higher settings allow reception of only the strongest stations, while lower settings let you receive progressively weaker stations.
XM Satellite Radio Ready: You can connect and control Pioneer's GEX-P920XM XM tuner (130P920XM, sold separately).

Hear the detail, warmth, and clarity, the way the artist intended it, from all of your highly compressed MP3 and WMA files stored on your USB device, iPod/iPhone, and portable media players. By restoring data (especially higher frequencies) that tends to get lost in the digital compression process, Pioneer's Advanced Sound Retriever technology enhances audio reproduction nearly all the way up to 20 kHz frequencies
Preset EQ: The Pioneer DEH-P8400BH is equipped with seven EQ presets. You can choose from Powerful, Natural, Vocal, Super Bass, Flat, Custom 1, or Custom 2.
Graphic EQ: The DEH-P8400BH's two Custom EQ modes (1 & 2) let you adjust the head unit's 5-band graphic EQ (100Hz, 315Hz, 1.25kHz, 3.15kHz, & 8kHz). You can adjust each band between +6 to -6.
Bass Boost: The Bass Boost function raises the level of sounds lower than 100Hz. You can select a desired level of bass boost between 0 and 6 (Gain: 0dB to +12dB).
Loudness: The Loudness feature compensates for deficiencies in the low and high sound ranges at low volume. You can set the Loudness feature to Low, Mid, High, or Off.
Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the volume level of the FM tuner, which remains unchanged. Each source can be independently adjusted from -4dB to +4dB.
Three Pair of 4.0-Volt Preamp Outputs: The Pioneer DEH-P8400BH features three pair of 4.0-volt preamp outputs (Front/Rear/Subwoofer). The unit's front and rear preamp output can be faded (front/rear), while the subwoofer preamp output is non-fading.
Crossovers: The DEH-P8400BH employs high pass and low pass crossovers to tailor the head unit to your connected speakers.
- High Pass: The head unit's 12dB/octave high pass filter only allows frequencies higher than those in the selected range (50, 63, 80, 100, 125Hz) to your front and rear speakers through the unit's speaker-level or line-level outputs.
- Low Pass: The subwoofer preamp output features an18dB/octave low pass filter so only frequencies lower than those in the selected range (50, 63, 80, 100, 125Hz) are output to your connected subwoofer.
Subwoofer Controls: The Pioneer DEH-P8400BH lets you adjust the subwoofer preamp output's phase (normal/reverse) and volume (+6 to -24).
Rear Channel Speaker Output: You can choose to use the rear channel output (speaker and preout) for full-range speaker or subwoofer. If you select "subwoofer", you can connect a 4-ohm subwoofer directly to each rear speaker lead, or a 2-ohm subwoofer to one of the rear speaker leads, without using an external amplifier.
Wireless Remote Control: The DEH-P8400BH comes with an IR wireless remote control. The remote allows you to control the volume, switch between sources, pause the CD, change the display, and adjust the audio. The mute button allows you to quickly lower the volume by about 90% (function that cannot be performed from the front panel). In addition, the remote provides answer/end phone controls for Bluetooth.
Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

They verify what’s in the box, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.
