Onkyo TX-NR579 instruction manual Reference Level, Dynamic Volume

■Reference Level

Audyssey Dynamic EQ® Reference Level Offset

`0dB:

This should be used when listening to movies.

`5dB:

Select this setting for content that has a very wide dynamic range, such as classical music.

`10dB:

Select this setting for jazz or other music that has a wider dynamic range. This setting should also be selected for TV content as that is usually mixed at 10 dB below film reference.

`15dB:

Select this setting for pop/rock music or other program material that is mixed at very high listening levels and has a compressed dynamic range.

Movies are mixed in rooms calibrated for film reference. To achieve the same reference level in a home theater system each speaker level must be adjusted so that –30 dBFS band-limited (500 Hz to

2000 Hz) pink noise produces 75 dB sound pressure level at the listening position. A home theater system automatically calibrated by Audyssey 2EQ® will play at reference level when the master volume control is set to the 0 dB position. At that level you can hear the mix as the mixers heard it.

Audyssey Dynamic EQ is referenced to the standard film mix level. It makes adjustments to maintain the reference response and surround envelopment when the volume is turned down from 0 dB. However, film reference level is not always used in music or other non- film content. Audyssey Dynamic EQ Reference Level Offset provides three offsets from the film level reference (5 dB, 10 dB, and 15 dB) that can be selected when the mix level of the content is not within the standard.

Note

•If “Dynamic EQ” setting is set to “Off”, these technologies cannot be used.

■Dynamic Volume

`Off

`Light:

Activates Light Compression Mode.

`Medium:

Activates Medium Compression Mode.

`Heavy:

Activates Heavy Compression Mode. This setting affects volume the most. It quiets the loud parts, such as explosions, and boosts the quiet parts so they can be heard.

Note

•If you make Dynamic Volume active, “Dynamic EQ” is set to “On”. The Dynamic Vol indicator will light.

•When “Dynamic EQ” is set to “Off”, “Dynamic Volume” is automatically switched to “Off”.

•These technologies cannot be used when:

–a pair of headphones is connected, or

–either Pure Audio or Direct listening mode is selected.

About Audyssey Dynamic EQ®

Audyssey Dynamic EQ solves the problem of deteriorating sound quality as volume is decreased by taking into account human perception and room acoustics. Dynamic EQ selects the correct frequency response and surround levels moment-by-moment at any user-selected volume setting. The result is bass response, tonal balance, and surround impression that remain constant despite changes in volume. Dynamic EQ combines information from incoming source levels with actual output sound levels in the room, a prerequisite for delivering a loudness correction solution. Audyssey Dynamic EQ works well by itself. However, if Audyssey 2EQ is on, the two technologies work in tandem to provide well-balanced sound for every listener at any volume level.

About Audyssey Dynamic Volume®

Audyssey Dynamic Volume solves the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies. Dynamic Volume looks at the preferred volume setting by the user and then monitors how the volume of program material is being perceived by listeners in real time to decide whether an adjustment is needed.

Whenever necessary, Dynamic Volume makes the necessary rapid or gradual adjustments to maintain the desired playback volume level while optimizing the dynamic range. Audyssey Dynamic Volume works fine by itself, but can also be used with

Audyssey Dynamic EQ. When both are on, Audyssey Dynamic EQ adjusts the perceived bass response, tonal balance, surround impression, and dialog clarity whether watching movies, flipping between television channels, or changing from stereo to surround sound content, when Dynamic Volume adjusts the volume.
