The highly acclaimed 192 kHz/32-bit ESS
SABRE

Ultra DAC (ES9016S) is adopted
to deliver exceptional sound, with ultra-low
distortion and high signal-to-noise ratio. It offers jitter-free
performance for an astounding audio reproduction with rich deep
bass, bringing out the full potentials of Pioneer’s Class D amplifiers.
Advanced Sound Retriever
89 87 85 82 81
The Advanced Sound Retriever restores the output
of compressed audio — such as WMA, MPEG-4 AAC,
and MP3 — to the level of CD sound. The technology
creates new signals to restore the minor details left out during
the compression process. Advanced Sound Retriever for multi-
surround sound is compatible with DVD soundtracks featuring
Dolby Digital or DTS.
Auto Sound Retriever
89 87 85 82 81
Since the Advanced Sound Retriever is designed
with an algorithm optimized to process 128 kbps
signal, it did not work well with 8-15 kHz high
frequencies in 64 kbps signal, which is the bit rate for quite a few
internet stations. The newly developed Auto Sound Retriever
automatically determines the audio signal’s bit rate, and
interpolates the data lost during compression. It is especially
effective for improving the sound quality of low bit rate content —
an ideal feature when switching between internet radio stations
with different bit rates.
Auto Sound Retriever for ARC
89 87 85 82 81
With digital broadcast, although images are displayed in high-
definition, the audio quality is not as high since they are
compressed with various bit rates. By applying Pioneer’s Auto
Sound Retriever feature to TV broadcast signals, it adjusts the
effects according to the bit rate transferred via HDMI’s ARC (Audio
Return Channel), letting you enjoy digital TV broadcast in high-
definition sound via Pioneer AV receiver.
Sound Retriever Link
89 87 85 82 81
Through HDMI connection, Sound Retriever Link
detects the original audio file information such as
source type, codec, and bit rate played on a
compatible Pioneer Blu-ray Disc player, and automatically
switches to the most suitable Sound Retriever. So there is no
need to switch on/off according to the source. Advanced Sound
Retriever is selected for Blu-ray Disc and DVD sources, and Auto
Sound Retriever is selected for other sources.
* Advanced Sound Retriever is selected for all sources when connected with a
non-compatible Blu-ray Disc player.
