DEX-P9R
COMPONENT CD RDS TUNER
❚ Full Digital System
Pioneer’s combination of the ultra-high-quality DEX-P9R component CD RDS
tuner and the DEQ-P9, a Universal Digital Preamp/Equaliser, creates a pure
audio system that redefines sonic excellence. Pioneer’s acclaimed hi-bit
technology converts the original 16-bit CD audio signal to 24-bits, which
improves signal linearity and maintains pure audio quality during digital
processing. The DEX-P9R has optical digital input for connecting Pioneer’s
XDV-P9 multi-DVD player, and optical digital outputs for connecting to the
DEQ-P9 off-board digital network. This network features 3 ultra-precise 51-bit
Digital Signal Processors to implement the 31-band graphic equalisation with
independent Left/Right control, Time Alignment and the 4-way digital network.
The DEQ-P9’s outputs are loaded
with six Burr Brown 24-bit multi-bit
DACs — the best of the best! Each of
the audio output channels features 2
separate DACs, arranged in Sign-
Magnitude conversion mode. This
eliminates zero cross distortion, and
offers an astounding S/N ratio and
an ultra-wide dynamic range. The
final result is unparalleled sonic clarity, faithfully reproducing the resonance of
the original recording in any car.
The DEX-P9R also functions as a stand-alone headunit. In this case, external
amplifiers can be used to drive the front and rear speakers as well as a
subwoofer over the non-fading pre-out. Each of the outputs from the DEX-P9R
features a 4 Hi-Volt pre-out, and the analogue conversion is done using Burr
Brown 24-bit multi-bit DACs.
To get the most from the DEX-P9R, however, Pioneer strongly recommends using
it in combination with the DEQ-P9. The DEQ-P9 has a 4-way output, for driving a
low-range woofer, a midrange speaker, a tweeter and a subwoofer. This can also
be adapted to a low midrange woofer, a tweeter, a subwoofer and full-range rear
fill speakers, if required. The external amplifiers are driven by the DEQ-P9’s
Hi-Volt outputs. These very high-quality outputs use their own balanced
plus/minus PWM power supply, to minimise noise and distortion.
Audiophiles will also appreciate Pioneer’s attention to detail.
The aluminium front panel and elegant blue OEL display of
the DEX-P9R are a sight to behold. For absolute perfection,
choose the display off mode to eliminate noise created by
the display’s power circuits. Special touches such as the
copper-plated chassis for reducing noise inducing eddy
currents, gold-plated RCA terminals and the use of 99.99 %
pure Oxygen-Free Copper in the RCA cables make these
products the acoustic perfectionist’s dream.

Pioneer’s lengthy experience with high-end audio systems continues with the DEX-P9R ultra-high-quality CD RDS component tuner.
The DEX-P9R transfers digital data directly from the CD to the audio processors, so you get as close as possible to the original
sound, with an absolute minimum of distortion and noise. The DEX-P9R can function alone, but when optically paired with the
DEQ-P9 high-tech digital preamp/equaliser, it forms a system with unrivalled audio, DSP and network functions. If you really want
to experience what this system is capable of, then make sure to use thoroughly engineered and pure sound-proven amps and
speakers, such as the PRS series. Go for an unparalleled listening experience.
DEQ-P9
DIGITAL PREAMP/EQUALISER
By adding this DSP unit to the DEX-P9R, the discerning driver can enjoy the versatility, sonic purity and
distortion-free control of digital signal processing and network functions. By converting the incoming
signal to digital form, it enables you to balance the output signal to match the acoustic characteristics
of your car and to create your personal sound profile by using the parametric equaliser and Sound Field
Control functions.
