7. DYNAMIC RANGE (Adjusting dynamic range)

Choices: MAX/STD/MIN

Preset position: MAX

* This adjustment is effective only when the Dolby Surround AC-

3 is decoded.

After selecting this function (title) in step 2 on page 36, press

the Parameter + or – key to display the choices MAX, STD and

MIN.

MAX: “Dynamic range” is the difference between the maximum

level and the minimum level of sounds. Sounds on a movie

originally designed for movie theaters feature very wide

dynamic range.

AC-3 technology can bring the original sound track into a

home audio format with this wide dynamic range

unchanged.

In this position, an AC-3 source is reproduced in the

original sound track’s wide dynamic range providing you

with powerful sounds like a movie theater.

Selecting this position will be more ideal if you can listen to

a source in a high output level in a room specially

soundproofed for audio/video enjoyment.
