Audio Section

24 Bit D/A Converter: The Pioneer in-dash head unit utilizes a 24-bit digital to analog converter for superior CD sound quality.

MOSFET Amplifier: The DEH-P8400BH is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.

CEA2006 Compliant: The power specifications for the DEH-P8400BH are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the DEH-P8400BH are as follows:

• CEA2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
• Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)
• Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)

3-Way Rotary Knob: The Pioneer DEH-P8400BH features a 3-way rotary knob combined with a 4-way lever for easy control. You can scroll through your music and audio settings with greater ease using the 3-way rotary knob and 4-way lever.

Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. 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.

Remote Control

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).
