About the Pioneer DEH-2500UI
A sleek, versatile platform
A sleek, versatile platform
Pioneer offers a fresh take on the lower-priced end of their car stereo lineup, and their DEH-2500UI CD receiver is strong on style and performance. Pioneer made the 12-character LCD display much larger so you can scope out song and artist info with a quick glance. The prominent buttons make it easy to access the intuitive menus and controls so you can get to the songs you want quickly.
Support for iPhone®
Plug your iPhone into the front USB port and you can enjoy your music while keeping your phone charged. You can also control your Pandora® Internet radio stations from the receiver, including "thumbs up" and "thumbs down."
Plenty of power plus sound customization
This Pioneer's MOSFET amplifier uses special transistors to deliver plenty of usable "real world" power — more than most factory car radios — so you'll enjoy crisp and clear sound even at highway speeds. And to tweak your tunes, you'll love the extra control afforded by the 5-band equalizer, 3-level loudness, and built-in frequency filters.
Pioneer's Advanced Sound Retriever reverses the compression process to add back some of the sonic info that's lost in the digital conversion. You'll notice a nice improvement in the sound quality of your MP3 and WMA music, whether it's stored on an iPod, a disc, or a thumb drive.

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-2500UI 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. The power specifications for the DEH-2500UI 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.
- 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
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. 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
Equalizer: The Pioneer DEH-2500UI 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 (except for USB/iPod/Pandora); while Custom 2 and the other 5 presets are shared settings used for all sources.
Bass Boost The DEH-2500UI 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.
2.0-Volt Preamp Outputs: The Pioneer DEH-2500UI features one pair of 2.0-volt preamp outputs. The unit's preamp output scan be configured as fading rear-channel outputs or non-fading subwoofer outputs with a low-pass filter, phase adjustment, and output level control.
Subwoofer Control: 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 (-6/-12dB), select the subwoofer phase (normal/reverse), and the subwoofer gain (+6 to -24).
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 -6dB or 12dB.
Switchable Rear Channel/Subwoofer Speaker Output: 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.
Supertuner 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 stations.
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 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.
Detachable Face Security: The Pioneer DEH-2500UI in-dash CD receiver features Detachable Face Security. A face-fixing screw is supplied for making the face non-detachable, if desired. No face case is included with this unit. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit.
LCD w/ LED Backlight: The DEH-2500UI features a single-line, multi-segmented LCD with LED backlight that offers a black background and white alphanumeric character text (up to 12 characters).
Display Illumination/Clock Display: When the Clock Display has been turned on, pressing and holding the "SRC" button turns off audio output, but the clock display and button illumination remains on (you can press the "DISP" button to turn off). When the Clock Display has been turned off, pressing and holding the "SRC" button turns the unit off completely. Even if you have turned the radio completely off you can view the clock display by pressing the "DISP" button. The clock will then remain On until you turn it back Off. When the unit is On, you can select between the clock display or the audio track/tuner display.
Demo Mode: This unit features a Demo mode which can be turned On/Off within the menu.
Wireless Remote Control: The DEH-2500UI 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. You can also mute the volume (function that cannot be performed from the front panel).
