External Device Controls
This receiver is equipped with a 45 watts x 4 (peak) MOSFET
amplifier for low distortion, high power output. The amplifier is strong
enough to power small subwoofers to moderate volume levels in compact cars and
pickups. For higher volume levels from subwoofers, an optional amplifier may be
connected to the provided sets of preamp outputs.
Illumination: The LED backlit multi-color display illuminates the
frequency and CD track/time in white and the mode indicators and the select
buttons guide in green. There is a bright blue EQ curve display in the left hand
portion of the display that shows the frequency response characteristic of each
curve (except the "CUSTOM" curve). The EEQ button illuminates in blue,
and all other buttons are backlit with green illumination.
This feature gives you a 3-Band Parametric EQ with Selectable Q Factor. You may
select a low (40, 80, 100 or 160Hz), mid (200, 500, 1k or 2kHz) and high
frequency (3k, 8k, 10k or 12kHz) to boost or cut. The Q factor (slope of the
boost or cut) may be selected from one of the following four options: 2N
(narrow/steep), 1N, 1W and 2W (wide/least steep). Selecting a narrow (steep) Q
factor results in frequencies around the center frequency to be affected less by
the boost or cut than they are with a wide Q factor. This feature is useful for
taming frequency response problems caused by the dimensions, materials and
speaker locations of a vehicle. A different "CUSTOM" curve can be set
into memory for each source; the built-in CD player and optional CD changer are
considered a single source, so they would share the same "CUSTOM" EQ
Curves: This model has "POWERFUL", "NATURAL",
"VOCAL", "CUSTOM", "EQ FLAT" and "SUPER
BASS" preset EQ curves. The "CUSTOM" curve is one that you create
and is stored in memory. There's an EQ curve display in the left hand portion of
the display that shows the frequency response characteristic of each curve
(except the "CUSTOM" curve; the displayed curve does not change with
the settings you make to the custom curve).
Rear Speaker Output
The rear speaker wires can be used to power a full range speaker
("Full Range output") or a subwoofer. If you switch the rear speaker
lead setting to "Sub woofer output", you can connect a subwoofer
directly to the rear speaker leads without using an external amplifier.
Image Enhancer) with Selectable Cutoff Frequency: Enhances the front
image by cutting mid and high range frequencies to the rear speakers (and the
preouts), limiting their output to low range frequencies. You may select a
cutoff frequency of 100, 160 or 250Hz.
You can select "Low", "Mid" or
"High" for different levels of loudness compensation.
Filter: Allows you to filter out bass frequencies from the internal
amplifier (front and rear speaker outputs). You can select 50, 80 or 125
Hz. The high pass filter can not be used when the F.I.E. function is used.
There is one set of outputs that may be set for full-range
output, "subwoofer" or "non fading" output. When set
to "non fading", the signal is full range and the output level is user
selectable. When set to "subwoofer", the outputs are non fading, and
they may be set for normal or reverse phase, 50Hz, 80Hz or 125Hz low-pass
output, and the level is user selectable from -6 to +6.
Adjustment (SLA): This function prevents radical leaps in volume when
switching between sources. To use this function, you compare the volume level of
the sources (AM, CD/CD changer, AUX) to the FM level, then you adjust the
sources level to match that heard when listening to FM. Since the reference
level is based on the FM volume, SLA is not possible on FM.
Mutes audio when a cellular call is received, then restores the level once the
call is over. To use this feature, you must
have a cellular
phone with a muting output that can be connected to the muting input wire of
This receiver is equipped with Pioneer's proprietary Supertuner III, which
provides excellent AM and FM performance.
rotary volume control allows for easy volume level adjustment. Normally, the
knob protrudes just slightly from the front of the face plate. To make the knob
easier to turn, it may be made to stick out further from the face; to make the
knob pop out, you simply press and release the knob. When the knob is in the
extended position, pressing the knob inward returns the knob to it's normal,
Dimming: When the illumination
wire of this unit is connected to the headlamp circuit of your vehicle, and you
turn your lights on, the display will dim to a preset level. The display
brightness is not affected by the vehicle's dimmer control.
CD Insert Auto
When unit is off and a CD is inserted it will automatically
turn on and play the CD.
The CD player has a pause feature, which also works for CDs played in optional
Pioneer CD changers.
You can store titles for up to 48 discs (when using a compatible Pioneer CD
changer this increases to a total maximum of 100 discs). Each title may be up to
10 letters long.
CD Compatibility: This
unit will play prerecorded CDs and finalized CD-Rs. The unit reviewed by
Crutchfield played a CD-RW disc, but Pioneer does not claim compatibility with
CD-RW discs. Results with CD-RW discs will vary depending on the quality of the
discs; there are audio CD-RW discs that this unit will not play.
AUX Title Input:
Allows you to input a title for the AUX input function;
(or item 130CDRB20), sold separately, is required to use the AUX input feature.
External Device Controls
IP-Bus Controls: The
DEH-P47D is equipped with IP-Bus control, which allows you to connect and
control other Pioneer components. You can add a multi-disc CD changer, a
satellite radio receiver, an auxiliary input adapter, or an iPod adapter.
The DEH-P47D will only support one external device plugged into its iP-Bus connector.
iPod Compatible: The optional Pioneer CD-IB100II iPod adaptor interface
allows an iPod, iPod Mini, iPod photo, iPod nano, or iPod video portable digital
music player with a dock connector to be hooked up to and controlled by the
XM Satellite Radio Compatible: This unit can control an optional XM Satellite Radio receiver (130P920XM). XM Satellite Radio features high-quality music, news, talk, sports, entertainment, and children's programming. For a monthly subscription fee, you'll be able to receive satellite radio signals in your car using an optional antenna and receiver.
CD Changer Controls: You can
add an IP-Bus-compatible 6-disc or 12-disc Pioneer CD changer, and control it
from the head unit. The unit feature the following CD-changer features.
- ITS (Instant
Track Selection) Programming:
The ITS function can be used to program automatic
playback of up to 99 tracks per disc for up to 100 discs. With changers sold
before the CDX-P1250 and CDX-P650, up to 24 tracks can be stored in the
- Direct Disc Selection: You
can directly select discs 1-6 by pressing the corresponding button number on
the front panel or remote. Discs 7-12 can be selected by pressing and
holding the corresponding button number, such as button 1 for disc 7, etc.
- CD Track Scan: The
beginning of each track on the selected disc plays for about 10 seconds
before moving onto the next track and continues until you make your
- CD Text
Display: When used with a CD
Text-compatible Pioneer CD changer, this unit will display the titles of CD
Text encoded discs that are played in the changer. When playing a CD Text
disc on a CD Text compatible changer, you cannot switch to the Disc Title
Input mode. CD Text disc titles, artist names and track titles longer than 8
characters may be scrolled once to reveal the entire string of text by
holding down the Display button.
- CD Sound
Quality Adjustment: Using the "COMP" (compression) and "DBE" (dynamic
bass emphasis) functions, you can adjust the playback quality of the
changer. Each function may be set to one of two levels or off.
The "COMP" function compresses the audio signal to
eliminate distortions caused by the imbalances between the loudest and
softest sounds when played at high volumes. The "DBE" function boosts bass
frequencies to give your music a more full sound.
Note: For these functions to work, they must be
supported by the Pioneer CD changer.
