Yamaha RX-V459 Manuel D’Utilisation

Compression artifacts (such as the MP3 format) are 
created by a lossy compression scheme where the audio is 
resampled to lower the bitrate and to remove sounds that 
are indistinguishable to typical human hearing. The 
Compressed Music Enhancer feature of this unit enhances 
your listening experience by regenerating the missing 
harmonics in a compression artifact. As a result, flattened 
complexity due to the loss of the high-frequency fidelity 
as well as lack of bass due to the loss of low-frequency 
bass is compensated, providing the improved performance 
of the overall sound system.

• The Compressed Music Enhancer mode is compatible with the 

PCM signals (32 kHz, 44.1 kHz and 48 kHz) and the analog 
2-channel input sources.

• The Compressed Music Enhancer mode is not effective with 

any of the sound field programs.

• When the Compressed Music Enhancer mode is turned on while 

an incompatible input source is being played back, “Not 
Available” appears in the front panel display.

• When the input source is changed to an incompatible input 

source while the Compressed Music Enhancer mode is turned 
on, the Compressed Music Enhancer mode is automatically 
turned off and the incompatible input source is played back in 
2-channel or 6-channel stereo.

Choices: 

, LOW

• Select “HIGH” for a high effect level.
• Select “LOW” for a low effect level.

Set the effect level to “HIGH” or “LOW” according to the 
characteristics of a source. The high-frequency signals of 
some sources may be emphasized too much. In this case, set 
the effect level to “LOW”.
