Concept S SW + R Dolby Digital/dts
Adjusting the surround system
Adjusting the time delay (“delay”)
In order for the device’s digital signal processor
(DSP) to convert Dolby signals perfectly, it must
be informed of the spatial positioning of the indi-
vidual speakers relative to each other.
The C. Delay (Centre)
P
and S. Delay (Surround =
rear speaker)
e
buttons on the remote control
are used for this.
the correct delay time is calculated as follows:
Centre delay
1.
Measure the distance between the listening
point and the front speakers.
2.
Measure the distance between the listening
point and the centre speaker.
3.
Subtract the distance of the centre from the
distance of the front speakers.
4.
Multiply the result by 3.
This gives you the delay time in milliseconds.
Example
Distance to the front speakers = 3.5 metres, dis-
tance to the centre speaker = 2.5 metres. Sub-
traction of the distances equals 3.5 – 2.5 metres
= 1.0 metre. When multiplied by 3, this results in
a 3ms delay time.
Information
The delay setting option for the
centre speaker is only provided in
the Dolby Digital and dts listen
modes.
The following rule of thumb
applies:
In small rooms up to 20m
2
, set a
delay value of 15 ms, in medium-
sized rooms (20m
2
- 35m
2
) set a
delay value of 20ms and in large
rooms over 35m
2
set a delay
value of 30ms.
Information
The setting option of the delay of
the rear speaker is only provided
in the Dolby Digital/dts and
Dolby ProLogic II listen modes.
Surround delay of the rear speaker
1.
Measure the distance between the listening
point and the front speakers.
2.
Measure the distance between the listening
point and the rear speakers.
3.
Subtract the distance of the front speakers
from the distance of the rear speakers.
4.
Multiply the result by 3, giving the delay time
in milliseconds.
Example
Distance to the front speakers = 3.5 metres, dis-
tance to the rear speakers = 1.5 metres. Subtrac-
tion of the distances equals 3.5 – 1.5 metres = 2.0
metre. When multiplied by 3, this results in a 6ms
time delay.
An additional 15ms are added as a constant to de-
lay times determined in this way. For the example
given above, this results in: 6 ms + 15 ms constant
= 21 ms delay time. As settings for the Concept S
SW+R Dolby Digital/dts are in increments of five,
choose the next possible value, i.e. 20ms.
