Listening to your system

Using the Advanced Sound Retriever

When audio data is removed during the compression

process, sound quality often suffers from an uneven sound

image. The Advanced Sound Retriever feature employs new

DSP technology that helps bring CD quality sound back to

compressed 2-channel audio by restoring sound pressure

and smoothing jagged artifacts left over after compression.

Press

S.RETRIEVER

to switch the S.RTV (Advanced

Sound Retriever) ON or OFF.

Note

• The Advanced Sound Retriever mode cannot be set to

when the

DIRECT

mode or the

PURE DIRECT

mode is

switched on.

Better sound using Phase Control

This receiver’s Phase Control feature uses phase correction

measures to make sure your sound source arrives at the

listening position in phase, preventing unwanted distortion

and/or coloring of the sound.

Phase Control technology provides coherent sound

reproduction through the use of phase matching for an

optimal sound image at your listening position. The default

setting is on and we recommend leaving Phase Control

switched on for all sound sources.

…

Press

PHASE

to switch the P.CTL (Phase Control) ON

or OFF.

Note

• Phase matching is a very important factor in achieving proper

sound reproduction. If two waveforms are ‘in phase’, they

crest and trough together, resulting in increased amplitude,

clarity and presence of the sound signal. If a crest of a wave

meets a trough, then the sound will be ‘out of phase’ and an

unreliable sound image will be produced.

•

If your subwoofer has a phase control switch, set it to the

plus (+) sign (or 0°). However, the effect you can actually

feel when Phase Control is set to ON on this receiver

depends on the type of your subwoofer. Set your

subwoofer to maximize the effect. It is also recommended

you try changing the orientation or the place of your

subwoofer.

•

Set the built-in lowpass filter switch of your subwoofer to

OFF. If this cannot be done on your subwoofer, set the

cutoff frequency to a higher value.

•

If the speaker distance is not properly set, you may not

have a maximized Phase Control effect.

•

The Phase Control mode cannot be set to ON in the

following cases:

When the PURE DIRECT mode is switched on.

When the headphones are connected.

Setting the Audio options
