Sound Retriever AIR
89 87 85 82 81
When streaming music via Bluetooth*, the sound
quality often suffers due to the compression
process. Pioneer’s Sound Retriever AIR is the
world’s first technology for improving the quality of Bluetooth
transmitted sound. It restores the music cadence lost through
compression, and also reduces the noise generated by Bluetooth
transmission resulting in a better S/N ratio.
* AS-BT200 optional adapter required
Auto Level Control
89 87 85 82 81
Auto Level Control equalizes volume level
differences between tracks when playing music
from an iPod or other sources. Multi-channel Auto
Level Control supports surround sound playback,
maintaining a consistent level and clear audio. The function
adjusts low and high frequency sounds, dialogs, surround
effects etc. that are difficult to hear in low volume, to optimal
levels — an ideal feature for listening at night without disturbing
others.
PQLS with HDMI
89 87 85 82 81
With the precision quartz controller on the AV
receiver, Pioneer’s Precision Quartz Lock System
(PQLS) eliminates distortion caused by timing errors.
It controls the amount of audio signals from the AV
receiver to the compatible player, giving the best
possible digital-to-analog conversion.
Three types of PQLS are available on the AV receivers depending
on the connected Blu-ray Disc player (see compatibility chart on
right).
- PQLS 2ch Audio: For CD playback.
- PQLS Multi-Surround: For CD/DVD/BD playback, when the
Blu-ray Disc player output is set to LPCM.
- PQLS Bit-stream: For CD/DVD/BD playback, all the time.
For PQLS to be effective, Control with HDMI needs to be on, and
PQLS setting needs to be set to Auto.
