PQLS Bit-stream
This latest PQLS technology allows jitter-less bit-stream
signal transmission from a compatible Pioneer Blu-ray Disc
player for CD audio and DVD/Blu-ray Disc multi-channel
content, letting you enjoy three-dimensional sound full of
detail.
Jitter Reduction Plus
LX83 LX73 LX53
With the high-accuracy digital/analogue PLL preceding the DAC,
the Jitter Reduction Plus feature further reduces jitter and
phase noise. The high-accuracy PLL circuit and the new jitter
reduction IC combine to create a precise sound stage and a
natural sound field at the same time. The technology is effective
for all inputs*.
* Except Pure Direct analogue input
Advanced Sound Retriever
LX83 LX73 LX53
Pioneer's latest A/V receivers feature the Advanced
Sound Retriever, which restores the output of
compressed audio — such as WMA, MPEG-4 AAC,
and MP3 — to the level of CD sound. The Advanced Sound
Retriever creates new signals to restore the minor details left
out during the compression process.
Multi-Channel Advanced Sound Retriever
Advanced Sound Retriever for multi-surround sound is
compatible with DVD soundtracks featuring Dolby Digital or
DTS.
Auto Level Control

Auto Level Control equalises volume level
differences between tracks when playing music
from an iPod or other sources.
Multi-Channel Auto Level Control
Multi-channel Auto Level Control supports surround sound
playback, maintaining a consistent level and clear audio
even at a low volume.
