Audyssey Dynamic EQ

Music, movies and games are typically mixed at fairly high volumes but

played back at more modest levels in a domestic setting.

Because the response of the human ear varies with level, the perceived

frequency response and surround eld in a domestic environment can at

various levels be altered from that actually intended.

Audyssey Dynamic EQ

attempts to solve this problem by taking into account

human perception, room acoustics and information from both incoming

source levels and actual output sound levels in the room.

Audyssey Dynamic EQ works in tandem with Audyssey 2EQ to vary the EQ

applied to the speakers in sympathy with the acoustic level to achieve a tonal

balance and surround impression that remain constant despite changes in

volume.

When Audyssey Dynamic EQ is turned on an option for Dynamic EQ offset

appears.

Movies are mixed in rooms calibrated for a standard lm reference.

Audyssey Dynamic EQ is referenced to this standard lm level and makes

adjustments to maintain the reference response and surround envelopment

relative to it.

However, the lm reference level is not always used in music or other non-

lm content.

To allow for this the Dynamic EQ Offset provides four settings that can be

selected , three for when the mix level of the content is not lm standard.

0 dB (Film Ref): This is the default setting and should be used when listening

to movies.

15 dB: For pop/rock music or other program material that is mixed at very

high listening levels or with a compressed dynamic range.

10 dB: For jazz or other music that has a wide dynamic range. This setting

should also be selected for TV content as that is usually mixed at 10 dB

below lm reference.

5 dB: For content that has a very wide dynamic range, such as classical

music.

Audyssey Dynamic Volume

attempts to solve 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 current volume setting and then monitors the

program material in real time, whenever necessary, Dynamic Volume makes

the necessary rapid or gradual adjustments to level maintain the desired

playback volume level.

The idea is that perceived bass response, tonal balance, surround

impression, and dialog clarity remain the same whether watching movies,

ipping between television channels, or changing from stereo to surround

sound content.

Audyssey Dynamic EQ is integrated into Dynamic Volume so turning on

Dynamic Volume also turns on Dynamic EQ.

Dynamic Volume has three settings (and Off)

Heavy: This has the narrowest dynamic range. If you want to watch an action

movie late at night and not wake up your family use Heavy.

Medium: This is the most common setting for daily television use in a living

room setting and works well to tame the volume increases of advertisements.

Light: This setting offers a wider dynamic range and can be used when

watching an action lm where you want a full dynamic experience but want

to make the dialog consistently audible.

Off: The full dynamic range is left untouched.

When the auto setup of the 751R V2 is completed successfully, the 751R

V2 displays a 'Measurement Complete' screen and then shows the Advanced

Audyssey Setup screen as per following section.

If you have just perfomed Audyssey autosetup & 2EQ you will see 2EQ is

enabled plus you can now enable Audyssey Dynamic EQ and/or Dynamic

Volume as well (if desired).

If you have just perfomed a simple Audyssey autosetup you will see 2EQ is

disabled (and cannot be enabled) but you can still enable Audyssey Dynamic

EQ and/or Dynamic Volume (if desired). See next section for full details.

To simply accept the settings by pressing the (I/O) button to exit the menu.

To accept the settings, simply press the (I/O) button and press again to exit

the menu.

The Speaker Distance crossover and Level Calibration settings for each

speaker will have been updated.

It is of course now possible to go into the Speaker Delay and Level

Calibration menus if you want to manually check/adjust the settings made

by the system, and it is always advisable to check them as no system can

be totally foolproof.

To exit the auto setup menu of the 751R V2 continue to press the OSD

button on the remote control to exit all menus or until 'OSD 'is no longer

displayed on the front panel. You can now unplug the microphone and put

it away for future use.

Notes:

– Some speakers such as bi-polars that radiate in more than one direction

can make it difcult for autosetup to accurately measure their level and

distance from the listening position.

– Active subwoofers with DSP have a small delay time built into their

electronics. Because the 751R V2 measures the total delay time including

any in-built delay it will still apply the correct amount of delay that when

added to the inbuilt delay gives the correct response. However the distance

reported in this case will be a little more than the physical measurement.

– If a subwoofer is present the autosetup treats most speakers as 'Small'

and sets a low crossover point (unless they genuinely have a bass

response lower than 40Hz).

This does not mean they are physically small it just means that the system

will automatically send the very low bass (only) from these channels to the

subwoofer for the best system response.

In all cases it is always advisable to manually check the settings autosetup

has made for a 'reality check' to ensure there are no obvious errors.

Advanced Audyssey

Further to Room EQ which can only be enabled if an Audyssey & 2EQ

procedure has been completed, it is possible to enable two extra Audyssey

features (which are by default disabled).

Select 'Advanced Setup' from the main OSD menu. Then select 'Advanced

Audyssey':
