Audio & DSP 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-X1900UB 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
- 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
Note: The power specifications for the DEH-X1900UB 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.
2V/2Ch Preouts + Sub Control: The Pioneer DEH-X1900UB features one
pair of 2.0-volt preouts. The unit's preouts can be configured as
fading rear-channel outputs or non-fading subwoofer outputs. When the head unit's preamp output is
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-X1900UB 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.
Audio Level Settings: The Pioneer DEH-X1900UB CD receiver
offers a variety of audio settings to tailor the bass, treble, and volume level
to your preference.
- Bass Boost The DEH-X1900UB 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.
IIID AM/FM Tuner: 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.
- RDS: The Radio Data System (RDS) feature displays radio broadcast
information such as artist, title, and album when listening to compatible AM/FM
- BSM (Best Stations Memory): The BSM (Best Stations Memory) function
lets you automatically store the six strongest 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
- Local Tuning: Local seek tuning
lets you tune in only those radio stations with sufficiently strong signals for
good reception. There are 4 levels 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.
Display & Remote Features
Detachable Face Security: The Pioneer DEH-X1900UB in-dash CD
receiver features detachable face security. No face case is included with this

MIXTRAX Illumination: MIXTRAX features a club-style
illumination that enhances the mood with a dynamic dance club-like lighting
effect when listening to USB MSC tracks (not compatible with Android or other
sources). As MIXTRAX begins, lights start pulsing to the beat of the music,
adding an extra level of entertainment. You can choose different patterns of
lighting variations from sound pressure level or low-pass synchronization modes.
The lighting effects work like a spectrum analyzer, reaching peak colors based
on the intensity of the music.
