Audio Section

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

MOSFET Amplifier: The DEH-X4900BT 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 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

4ch/2V Preouts + Sub Control: The Pioneer DEH-X4900BT features two pair of 2.0-volt preouts (Front & Rear/SW). The unit's Rear/SW preouts can be configured as fading rear-channel outputs or a non-fading subwoofer outputs. When the head unit's RW/SW preouts are configured as a subwoofer output, you can select the frequency of the low pass filter (50Hz, 63Hz, 80Hz, 100Hz, or 125 Hz), select the filter slope (-12/-24dB), select the subwoofer phase (normal/reverse), and the subwoofer gain (+6 to -24).

Equalizer: The Pioneer DEH-X4900BT features a Preset & Custom EQ. The built-in equalizer offers 7 preset sound modes (Powerful, Dynamic, Vocal, Natural, Custom 1, Custom 2, and Flat) suitable for the music genre of your choice. The two Custom modes allow you to manually adjust the head unit's 5-band EQ (80Hz, 250Hz, 800Hz, 2.5kHz, 8kHz) from +/-6dB. Custom 1 can be set separately for each source, while Custom 2 and the other 5 presets are shared settings used for all sources.

High-Pass Crossover: When you don't want low-frequency sound to be heard through your front or rear speakers, you can simply active the head unit's HPF (high pass filter). By activating the HPF, only frequencies higher than those in the selected range are output from the front or rear speakers. The high pass filter crossover can be set to 50Hz, 63Hz, 80Hz, 100Hz, 125Hz, 160hz, 200Hz or Off. The slope level of the HPF can also be adjusted to -12dB or 24dB.

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, iPod/iPhone, and Android devices. 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

Audio Level Settings: The Pioneer DEH-X4900BT CD receiver offers a variety of audio settings to tailor the bass, treble, and volume level to your preference.

• Bass Boost The DEH-X4900BT features a bass boost function which can be used to enhance low-frequency bass sound. The bass boost function can be set between 0-6.
• 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.

Rear Speaker Setup: The rear speaker outputs can be set to provide full range output with full fading capability, or they can be set to provide non-fading subwoofer (low-pass) output. When the rear speaker outputs are set to subwoofer mode, the rear preamp outputs also switch from full range to subwoofer outputs. When set for subwoofer operation, you can connect the rear speaker leads directly to two small 4-ohm passive subwoofers or a dual voice coil sub with 4-ohm voice coils. If you prefer to use a single 2-ohm subwoofer, you can connect the woofer to one set of speaker leads, leaving the other set of rear leads disconnected. The maximum output provided when a 2-ohm load is connected to one set of leads is 70 watts.
