signals to be able to hear the low level signals at realistic average sound levels (e.g.
the sound of leaves rustling in the wind). In addition, the low level boost can
increase understanding of speech, especially in noisy environments.
It may also be desirable to limit the peak sound level, so as not to disturb your
neighbours at night.
The following settings are possible:
DYNAMIC HI
(DTS + Dolby Digital)
High-level limit:
0.0 (disable high-level limit function)
0.1
0.2
0.4
0.6
1.0 (maximize high-level limit function)
DYNAMIC LO
(Dolby Digital)
Low-level boost:
0.0 (disable low-level boost)
0.1
0.2
0.4
0.6
1.0 (maximize low-level boost)
6.7 Volume scale
It is possible to select two different volume scale settings: a progressive step size,
where step size is larger at low levels for rapid setting and small at normal listening
levels, or alternatively a fixed more precise but slower to use 0.5dB step size.
The default selected progressive step size is more convenient for most users and is
therefore called “normal”, while the fixed step size scale is called “full”:
“normal”:
0.0, 5.0 , 10.0, 15.0, 20.0, 22.0, 24.0,......38.0, 40.0, 41.0,
42.0,..... , 68.0, 69.0, 70.0, 70.5, 71.0, 71.5,..... , 99.5, 100
“full”:
fixed 0.5dB step size from 0.0 to 100 ( 200 steps).
6.8 Saving set-up parameters in the memory bank
In the menu
MEM BANK,
you can store the set-up parameters in four memory
banks, one for each surround mode:
Stereo, ProLogic II, Dolby Digital
and
DTS
.
The following parameters are saved:
-
Channel volume trims (L, C, R, SL, SR, SUB and LFE)
-
Channel delay (SL, SR, C, SC)
-
Speaker configuration (speaker size and crossover frequencies)
-
Subwoofer max bass (accumulated mono signal sent to the subwoofer)
When you have completed your settings for one of the four above-mentioned
modes, you can save your settings by choosing the correct memory bank (
Stereo,
ProLogic II, Dolby Digital or DTS
) by pressing “
⇒
“ followed by “ENTER”.
The saved parameters will be reloaded each time a surround mode is changed.
