Pioneer Elite BDP-09FD - Manual (Page 7)

Eight Wolfson ® Microcelectronics
Digital-to-Analog Converters
To maximize audio fidelity, Pioneer used a separate stereo
digital-to-analog converter for each of the BDP-09F D’s
7.1 channel s. Each 24-bit /192-kilohertz DA C runs in
differential mode to cancel noise and interference, and
helps the BDP-09F D achieve its impressive 120-decibel
signal-to - noise ratio.
State-Of-The-Art Audio Decoding
The BDP-09FD decodes all audio formats currently used for
Blu-ray Disc and DVD, including DTS-HD
® Master Audio * ,
Dolby ® True HD, DTS-HD High Resolution Audio, and Dolby
Digital Plus. These may be heard through the player’s analog
outputs, decoded in the player and sent out as uncompressed
PCM audio, or sent out for decoding in an audio/video receiver
or surround-sound processor.
Toroidal Transformer
Power-supply transformers create powerful magnetic fields
that can affect the operation and performance of audio
circuitry. The BDP-09FD’s round toroidal transformer—the
same type used in almost all high-end stereo equipment—
produces a tighter, more contained magnetic fiel d than
a typical EI-type transformer.
PQLS Jitter-Free Audio Transmission
Pioneer’s Precision Quartz Lock System (PQLS) reclocks
HDMI digital audio for jitter-free performance when the BDP-
09FD is used in conjunction with a PQLS-equipped Pioneer
audio / video receiver. PQLS produces clearer transients,
more realistic ambience, and deeper silence.
Custom Capacitors
Off-the-shelf power-supply capacitors sometimes vary as
much as 50 percent from their stated value. Pioneer created
tight-tolerance, custom capacitors designed for low internal
resistance and inductance, to ensure that the power supply
delivers its specified performance.
Dedicated Analog Audio Power Supply
The rapid on /off nature of digital circuitry can cause high-
frequency fl uctuations in a power supply—fl uctuations that
can impair sound if the analog audio circuitry is powered by
the same supply. The BDP-09F D uses a separate power
supply for anal og audio to pr e vent such cont amination.
