The following summary exemplifies menu control for you:
SURROUND DELAY OF THE SPEAKER CHANNELS
(“DELAY” KEY)
In order to achieve a homogeneous sound field at
your position in the room, it is necessary to adjust the
delay times for the Rear speaker channels and the
Center speaker channel.
This is necessary, because in a speaker arrangement
typical for a living room the front speaker distance to
the listening position is usually larger than the rear
speaker distance to the listeners. Irritations of the per-
ception of direction by early surround signals are
avoided by delaying the signal for the rear speakers.
In some speaker arrangements a delay time must also
be adjusted for the Center speaker. As the result the
sound signals of all speakers arrive at the listener at
the same time.
In the mode Prologic 2 additional 15ms (milliseconds)
of delay cause the back channel sound to arrive later
than the front channel sound. This is part of the “Dolby
Surround Prologic” specification and reduces audibili-
ty of sound fractions crosstalked from the front chan-
nel signals and makes sure that the audio information,
that is important for sensual location of acoustic sour-
ces, is first obtained from the front channels.
The SAV-C1 allows Surround delay times from 0ms to
15ms (milliseconds) in the „Dolby Digital“ (“DIG5.1”
and DIG.EX”) modes and from 15ms to 30ms in the
„Prologic II“ (“PLOGII”) mode. Additionally, in the
„Dolby Digital“ modes, a Center delay time in the
In order to adjust the required delay settings proceed as follows:
range 0ms...5ms must be set. All this has to be done
after first installation of the system and to be repeated
everytime the speaker distances are changed.
These settings are only effective in the Dolby Digital (“DIG5.1” and “DIG.EX”), and Dolby Prologic
II („PLOGII“) audio playback modes. They can only be carried out while one of these sound play-
back modes is selected. To that end, a preamplifier input that supports these modes (see chapter
“Sound playback modes (“MODE” key), must be selected.
The settings for Dolby Digital and Dolby Prologic II will be stored separately. No Centre channel
delay can be set for Dolby Prologic II.
No separate signal delay can be set for the Rear Centre channel.
If the centre or rear speakers are further away from the listening point than the front speakers, no
delay can be set for the front speakers. In that case leave the values at their minimum setting.
Surround delay time in Dolby Digital mode
Measure the distance from your listening position to the front left or right speaker. Subtract from this value
the distance from the listener’s position to the rear speakers. Each 30cm of this difference should be related
with a delay time of 1ms. Round to the closest multiple of 30cm. For example, a length difference of 120cm
results in a required delay time of 4ms. The maximum value is 15ms.
Center delay time in Dolby Digital mode
Measure the distance from your listening position to the Center speaker and to one of the front speakers.
Subtract the Center distance from the Front speaker distance. Again, 30cm of this difference should be rela-
ted with a delay time of 1ms. Round to the closest multiple of 30cm. If the Center speaker is about 50cm clo-
ser to the listener, 2ms of delay time should be applied. The maximum value is 5ms.
Surround delay time in Dolby Prologic II mode
Add 15ms to the Surround delay time in Dolby Digital mode.
Setting the delay times for Dolby Digital
Select an input channel with digital sound connection (“CD/AV1”, “DVD/AV2”, “SAT/AUX1” or “D-
TV/AUX2”). If necessary, select a digital sound format (“IN MODE” key (6)(22)). Now use the “MODE” key
(7)(26) to select either “DIG.EX” or “DIG5.1” as the audio playback mode Now press the “DELAY” key (29).
Use the “SET” keys (31) to set the value calculated for the Surround channels in the Dolby Digital mode. Enter
the value for the centre channel in the same way after pressing the “DELAY” key (29) again.
If nothing is entered for several seconds, the Setting mode is returned to the standard mode.
Setting the delay time for Dolby Prologic II
Select one of the preamplifier input channels (“SAT/AUX1” or “D-TV/AUX2”, “VCR/AUX3” or
“TUNER/AV3”). If one of the inputs “D-TV/AUX2” or “SAT/AUX1” was selected and this is necessary, switch
to an analogue sound connection (“IN MODE” key (6)(22)). Now use the “MODE” key (7)(26) to select eit-
her “PLOGII” as the audio playback mode. Now press the “DELAY” key (29). Use the “SET” keys (29) to set
the value calculated for the Surround channels in the Prologic II mode.
If nothing is entered for several seconds, the Setting mode is returned to the standard mode.
