Onkyo TX-NR808 instruction manual Reference Level, Dynamic Volume

■Reference Level

Audyssey Dynamic EQ® Reference Level Offset

`0dB:

It 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 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 MultEQ® 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 mix- ers 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. 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”, this setting cannot be selected.

■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

•Even if you have selected other than “Audyssey” in “Equalizer” setting after performing Audyssey MultEQ Room Correction and Speaker Setup, selecting “On” in the “Dynamic EQ” will change the “Equalizer” setting to “Audyssey” (➔ 47).

•If you would like to use Audyssey Dynamic Volume, when using THX listening modes, set “Loudness Plus” setting to “Off” and set “Preserve THX Settings” setting to “No” (➔ 48).

•When “Dynamic Volume” is set to effective, “Equalizer” is set to “Audyssey” (➔ 47) and “Dynamic EQ” is set to “On”. When “Dynamic EQ” is set to “Off”, “Dynamic Volume” becomes “Off” automatically.

•When “Dynamic Volume” is set to effective, the Dynamic Vol indicator will light (➔ 9).

•If Pure Audio or Direct listening mode is selected, this setting cannot be selected.

Audyssey MultEQ then removes the distortion caused by room acoustics by capturing room acoustical problems over the listening area in both the frequency and time domain. The result is clear, well-balanced sound for every- one. Enabling Audyssey MultEQ allows you to also use Audyssey Dynamic EQ, which maintains the proper octave-to-octave balance at any volume level.

Before using this function, connect and position all of your speakers.

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 MultEQ 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.
