Onkyo Comprehensive Guide to Audyssey Dynamic Volume and Dynamic EQ Reference Level Offset for TX-SR508

Note

• Audyssey equalizing does not work for DSD sources.

■Dynamic EQ

`Off:

Audyssey Dynamic EQ off.

`On:

Audyssey Dynamic EQ on.

The Dynamic EQ indicator will light (➔ 8). With Audyssey Dynamic EQ™, you can enjoy great sound even when listening at low volume levels. Audyssey Dynamic EQ solves the problem of deterio- rating sound quality as volume is decreased by taking into account human perception and room acoustics. It does so by selecting the correct frequency response and surround volume levels moment-by-moment so that the content sounds the way it was created at any volume level — not just at reference level.

Note

•The setting is stored individually for each input selector.

•If Pure Audio (European and Asian models) or Direct listening mode is selected, this setting cannot be selected.

■Reference Level

Dynamic EQ Reference Level Offset

`0 dB:

It should be used when listening to movies.

`5 dB:

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

`10 dB:

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.

`15 dB:

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

Movies are mixed in rooms calibrated for film refer- ence. To achieve the same reference level in a home the- ater 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 cali- brated by Audyssey 2EQ will play at reference level when the master volume control is set to the 0 dB posi- tion. 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 ref- erence response and surround envelopment when the volume is turned down from 0 dB. However, film refer- ence level is not always used in music or other non-film content. The Dynamic EQ Reference Level Offset pro- vides 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”, this setting cannot be selected.

•The setting is stored individually for each input selector.

■Dynamic Volume

`Off:

Audyssey Dynamic Volume™ off.

`Light:

Light Compression Mode becomes active.

`Medium:

Medium Compression Mode becomes active.

`Heavy:

Heavy Compression Mode becomes active. This set- ting affects volume the most, causing all sounds to be of equal loudness.

Note

•If you make Dynamic Volume™ active, “Audyssey” and

“Dynamic EQ” settings are set to “On”. The Dynamic Vol indi- cator will light (➔ 8).

•The setting is stored individually for each input selector.

•If Pure Audio (European and Asian models) or Direct listening mode is selected, this setting cannot be selected.

About Audyssey Dynamic EQ

Audyssey Dynamic EQ solves the problem of deterio- rating 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 con- stant despite changes in volume. Dynamic EQ combines information from incoming source levels with actual output sound levels in the room, a prerequisite for deliv- ering a loudness correction solution.

Audyssey Dynamic EQ works in tandem with Audyssey 2EQ 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. When- ever necessary, Dynamic Volume makes the necessary rapid or gradual adjustments to maintain the desired playback volume level while optimizing the dynamic range. Audyssey Dynamic EQ is integrated into Dynamic Volume so that as the playback volume is adjusted automatically, the perceived bass response, tonal balance, surround impression, and dialog clarity remain the same whether watching movies, flipping between television channels, or changing from stereo to surround sound content.
