Control with HDMI function

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-37 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 45 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-37 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-37 only) or STEREO is selected.
