Build your ideal system.
The audio can be tuned to your tastes through the 7-band graphic equaliser. It allows you to adjust the equalisation to match the distinct interior acoustic characteristics of your car.
An Automatic Sound Leveliser (ASL) uses signal processing to optimally adjust the internal volume, compensating for the outside noise: what you hear is always perfected, whatever the driving conditions.
And of course, you can enjoy your entire music collection on the road, too. Play audio from your portable USB device, MP3 player – simply use the front-in USB and Auxiliary inputs. The DEH-P5100UB is even ready for your iPod or iPhone using the optional CD-IU50.
The large, cool blue OEL (Organic Electro Luminescent) display shows moving images and detailed information, making searching and selecting tracks quick and easy.
You also have the option of going wireless and adding full Bluetooth handsfree and audio streaming functionality by adding an optional adapter.


Cellular telephone auto muting
This feature automatically reduces the volume of your system when an incoming call is detected or you dial an outgoing call on a cellular phone installed in your car.RCA Preout
Thanks to the RCA pre-outs, it is easy to expand your sound system. You can significantly improve your in-car sound quality by connecting extra amplifiers to your headunit. You could customize your sound system with separate amplifiers for the front speakers, the rear speakers and a subwoofer. Combining Pioneer 's EEQ+ with the RCA pre-outs let you create the exact sound you want, with the focus on complete flexibility!
Direct Sub Drive
Combine the MOSFET 50Wx4 power amp and EEQ Plus technology to get Direct Sub Drive, another unique Pioneer technology feature. It enables you to amplify your front speakers by 2 x 50 W and add a 70 W amplified filtered subwoofer (in 2 Ohm mode) in the rear to enjoy outstanding full power bass without an extra amplifier. It's an easy solution for lovers of booming bass.High Voltage Output
To provide a high output to your amplifier, Pioneer has built a special High Voltage Preamp circuit yielding no less thatn 4 V non-clipping output to the preout terminal. Such a high output voltage means the power amplifier does not have to work so hard to produce sufficient gain to give high volume levels. As a result, even a low gain power amplifier can be used, giving excellent sound quality with low noise.Radio Data System (RDS)
RDS (Radio Data System) is a system for pro-viding information along with FM broadcasts. This inaudible information provides such fea-tures as program service name, program type, traffic announcement standby, automatic tuning and program type tuning, intended to aid radio listeners in finding and tuning in to a desired station. Note: • RDS service may not be provided by all stations. • RDS functions like AF (alternative frequencies search) and TA (traffic announcement standby) are only available when your radio is tuned in to an RDS station.Best Stations Memory (BSM)
Best Stations Memory scans and memorises the six strongest, clearest stations available on each band.PTY Search
A PTY search is performed by program type as indicated in the PTY list (the program types are: News&Inf, Popular, Classics, Others). It also provides automatic tuning to emergency broad-casts (PTY alarm).CD Text
CD Text allows various text information to be added to normal music CDs. By pushing the Display key, it is possible to scroll between disc title, track title and artist name (usable with compact discs featuring CD Text).
Last Position Memory
Last Position Memory automatically resumes CD play from the last point if there is interruption to CD play.Loudness
At low volume levels, low and high frequency sounds in music can be overpowered by ambient noise levels in the vehicle. Loudness control provides a one-button way to boost these frequencies and provide better overall sound at low volume levels.high pass filter
When the subwoofer is connected and you do not want low sound to play from the front or rear speakers, turn the high pass filter on. Only fre-quencies higher than those in the selected range will be output from the front or rear speakers.Source Level Adjuster (SLA)
Source Level Adjuster (SLA):Allows you to independently adjust the volume ratio between all of the headunit's sources (using the FM volume level as a reference), so the start-up volume between sources will always be the same.specifications
