Adjusting Delays And Dynamic Range - Yamaha DDP-1 Owner's Manual

ADJUSTING DELAYS AND DYNAMIC RANGE

This unit provides you with the following functions to make the AC-3 sound field suitable for the conditions of your listening room.
Description of each function
A1. CENTER DELAY
Control range: 0 ms to 5 ms (in 1 ms step)
Preset value: 0 ms
Adjusts the delay between the main sounds (at the main
channels) and dialog etc. (at the center channel).
The larger the value, the later the dialog is generated.
A2. SURROUND DELAY
Control range: 0 ms to 15 ms (in 1 ms step)
Preset value: 5 ms
Adjusts the delay between the main sounds (at the main
channels) and the effect sounds (at the surround channels).
The larger the value, the later the effect sounds are generated.
A3. DYNAMIC RANGE
Choices: MAX/STANDARD
Preset position: MAX
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.
STANDARD:
Powerful sounds of extremely wide dynamic range
are not always suitable for home use. Depending
upon the condition of your listening environment, it
may not possible to increase the sound output level
as high as a movie theater, however, in a level
proper for listening to in your room, the low level
parts of source sound cannot be heard as well
because they will be lost among noises in your
environment.
AC-3 technology also makes it possible to reduce an
original sound track's dynamic range for a home
audio format by "compressing" the data.
In this position, an AC-3 source is reproduced in the
"compressed" dynamic range of the source suitable
for low level listening.
If you desire, you can also adjust the dynamic range
on function A4 and A5 only when this position is
16
selected. (See the right side for details.)
A1. CENTER DELAY
A2. SURROUND DELAY
A3. DYNAMIC RANGE
A4. HIGH LEVEL CUT SCALE
A5. LOW LEVEL BOOST SCALE
A4. HIGH LEVEL CUT SCALE
Control range: 0.0 to 1.0 (in 0.2 step)
Preset value: 1.0
Adjusts the dynamic range of high level signals of source. The
larger the value, the range is more reduced. The smaller the
value, the range is more widened.
Note: This function is available only when the "STANDARD"
position is selected on the function A3.
A5. LOW LEVEL BOOST SCALE
Control range: 0.0 to 1.0 (in 0.2 step)
Preset value: 1.0
Adjusts the dynamic range of low level signals of source. The
larger the value, the range is more widened. The smaller the
value, the range is more reduced.
Note: This function is available only when the "STANDARD"
position is selected on the function A3.
