Features

Overview: The Pioneer DEH-P4900IB AM/FM/CD receiver features a Mosfet amplifier, Super TunerIIID, Satellite Radio-Ready controls, built-in iPod interface (optional CD-i200 adapter required), three sets of RCA preamp outputs, a rear auxiliary input and CD-changer controls along with a fold-down and detachable face.

Mosfet Amplifier: The DEH-P4900IB delivers a full 22 watts x 4 channels RMS and 50 watts x 4 channels peak. 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.

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.

BSM (Best Stations Memory): BSM 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.

MP3/WMA/WAV Playback: This unit can play MP3/WMA/WAV files recorded on CD-ROM, CD-R, and CD-RW discs in ISO9660 Level 1/Level 2, Joliet, and Romeo formats. MP3 files with a bit rate from 8-320 kbps, WMA files with a constant bit rate from 48-320 kbps, and WMA files with a variable bit rate from 48-384 kbps are supported. The unit is compatible with ID3 Tags and will display artist, folder, file, and album name, plus comments. Up to 8 directories, 99 folders and 999 files per disc are recognized by this unit.

Note: When playing compressed audio, there is no sound on fast forward or reverse.

AAC Decoding: This unit will playback AAC files encoded by iTunes version 6.0.6 and earlier. Advanced Audio Coding (AAC) refers to an audio compression technology standard used with MPEG 2 and MPEG 4.

Digital Speedread2: The DEH-4900IB is equipped with Pioneer's Digital Speedread2 CD mechanism, which provides fast performance, especially for reading and playing discs with MP3/WMA/WAV files. It also shortens the audio gap between files during random playback.

AGC (Automatic Gain Control): The CD mechanism has a built-in Automatic Gain Control, which adjusts 7 different settings each time a CD is inserted to prevent the disc from skipping

EEQ (Easy EQ): The DEH-P4900IB is equipped with a 3-band parametric EQ with 6 preset EQ settings. You can boost or cut each frequency band by +/- 6dB at 1dB intervals. Features of the Easy EQ include:

• Selectable Center Frequencies:
  • Low: 40, 80, 100, or 160 Hz
  • Mid: 200, 500, 1k, or 2k Hz
  • High: 3k, 8k, 10k or 12k Hz
• Preset EEQ Settings: Powerful, Super Bass, Vocal, Natural, Custom, and EQ Flat
• Selectable Q Factors: 2 Narrow, 1 Narrow, 1 Wide, and 2 Wide

Selectable Loudness Levels: Loudness compensates for deficiencies in the low and high frequencies at low volumes. You can choose from three levels of loudness:

• Low: +3.5dB (100Hz), +3dB (10kHz)
• Mid: +10dB (100Hz), +6.5dB (10kHz)
• High: +11dB (100Hz), +11dB (10kHz)

Auxiliary Inputs: The DEH-P4900IB is equipped with a rear panel 3.5mm stereo minijack auxiliary input for connecting external components, such as a portable MP3 player, DVD, or VCR. Once AUX 1 is selected as a source, you can change the source display of the input to any 10-character name. A second auxiliary device can be connected to this unit when an optional adapter is connected to the IP-Bus connector on the rear panel. This auxiliary input (known as AUX 2) must be turned on, and an 10-character name for the input can be stored in memory. See below for more information on the 2nd Auxiliary Input.

2nd Auxiliary Input Ready: In addition to the rear panel minijack Aux input (AUX 1), you can connect a second auxiliary component by connecting an IP-Bus/RCA connector. The CD-RB10 lets you connect one auxiliary component, and the CD-RB20 lets you connect an auxiliary component and a CD changer via the IP-Bus connector on the back of the head unit. The 10-character name of the connected auxiliary component can be entered into memory, and will appear as you cycle through the sources.

Subwoofer Output: The unit has a pair of dedicated non-fading RCA subwoofer outputs with a low-pass filter, phase adjustment, and output level. When the subwoofer output is turned on, you can select the frequency of the 18dB/octave low pass filter (50, 63, 80, 100, or 125 Hz), select the subwoofer phase (normal/reverse), and the subwoofer gain (+6 to -24).

Switchable Rear Channel/Subwoofer 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.

High Pass Filter: If you do not want low frequency sounds to play from the front or rear speaker outputs, you can turn on the 12dB/octave High Pass Filter. The HPF has a selectable cutoff frequency (50, 63, 80, 100, or 125 Hz). Only frequencies higher than those in the selected range are output through the speakers.

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.

Front Image Enhancer (FIE): The Front Image Enhancer attenuates mid- and high-frequency sounds from the rear speakers at selectable crossover points, so that most of the vocals will come from the front speakers, giving you better image staging. You can select from the following cutoff frequencies: 100Hz, 160Hz, and 250Hz.

Compression and BMX Functions: Using the "COMP" (compression) and "BMX" (Bit Media eXpander) functions, you can adjust the playback quality of the CD player. Each function may be set to one of two levels or off. The "COMP" function compresses the audio signal to eliminate distortion caused by the imbalances between the loudest and softest sounds when played at high volumes. The "BMX" function controls sound reverberations to give playback a fuller sound.

Rough Search: You can switch the search method between fast forward/reverse and "Rough" in which the unit searches every 10 tracks. If there are less than 10 tracks on the disc, the unit will jump to the last track.

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.

Disc Naming: You can use the disc title input feature to store up to 48 CD titles in the unit's memory. Each title can be up to 10 characters long.

2-line, 16-Character Display: The DEH-P4900IB features a black background with a blue 2-line, 16-character (each) Organic EL display, which takes advantage of MP3, WMA, iPod, XM Radio, and Sirius, plus CD Text-encoded discs. This large display makes it easy to read and cycle through the song title, artist, and other text used by these sources.

Ever Scroll: When the Ever Scroll feature is set to On, recorded text information scrolls continuously on the display. It will auto-scroll up to 64 characters. Set this feature to Off if you prefer the information to scroll only once.
