Setting the PQLS function
PQLS (Precision Quartz Lock System) is a digital audio
signal transfer control technology using the
Control with
HDMI function. It offers higher-quality audio playback by
controlling audio signals from the receiver to a PQLS
compatible player, etc. This enables removing jitter that
has a negative effect on the quality of the sound and is
generated upon transmission.
• SC-LX83 only: On players compatible with PQLS Bit-
stream, PQLS always works for all sources.
• On players compatible with PQLS Multi Surround,
PQLS works for all sources. Set the player’s audio
output to Linear PCM.
• On players compatible with PQLS 2 ch Audio, PQLS
only works when playing CDs.
Please refer to the operating instructions supplied with
your player for more information.
This function is activated when Control is set to ON.
1
• Set the remote control to the receiver operation
mode, then press PQLS to select the PQLS setting.
The setting is displayed on the front panel display.
• PQLS AUTO – PQLS is enabled. A precision quartz
controller in this receiver eliminates distortion
caused by timing errors (jitter), giving you the best
possible digital-to-analog conversion when you use
the HDMI interface. This is valid as an HDMI function
for PQLS-compatible players.
• PQLS OFF – PQLS is disabled.
Cautions on the Control with HDMI
function
• Connect the TV directly to this receiver. Interrupting a
direct connection with other amps or an AV converter
(such as an HDMI switch) can cause operational
errors.
• Only connect components (Blu-ray disc player, etc.)
you intend to use as a source to the HDMI input of
this receiver. Interrupting a direct connection with
other amps or an AV converter (such as an HDMI
switch) can cause operational errors.
• When Control is set to ON, HDMI Input in The Input
Setup menu on page 44 is automatically set to OFF.
• When the receiver’s Control is turned ON, even if the
receiver’s power is in the standby mode, it is possible
to output the audio and video signals from a player
via HDMI to the TV without producing sound from the
receiver, but only when a
Control with HDMI-
compatible component (Blu-ray disc player, etc.) and
compatible TV are connected. In this case, the
receiver’s power turns on and the power and
HDMI
indicators light.
Note
1 • If a listening mode other than AUTO SURROUND, ALC, DIRECT, PURE DIRECT, OPTIMUM SURR (SC-LX83 only) or STEREO is selected while
the PQLS effect is enabled, the PQLS effect is disabled.
• When this receiver is connected by HDMI cable to a Pioneer player that is compatible with the PQLS function via HDMI connection and
HDMI reauthentication is performed (the
HDMI indicator blinks), the PQLS effect is enabled and the listening mode is set to AUTO
SURROUND if a listening mode other than AUTO SURROUND, ALC, DIRECT, PURE DIRECT, OPTIMUM SURR (SC-LX83 only) or STEREO is
selected.
