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.
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,
distance to the centre speaker = 2.5 metres.
Subtraction of the distances equals 3.5 - 2.5 me-
tres = 1.0 metre. When multiplied by 3, this results
in a 3 ms delay time.
Note
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 20 m², set
a delay value of 15 ms and in
medium-sized rooms (20–30 m²)
set a value of 20 ms.
Note
The setting option of the delay of
the rear speaker is only provided
in the Dolby Digital/dts and Dol-
by 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,
distance to the rear speakers = 1.5 metres.
Subtraction of the distances gives you 3.5 - 1.5
metres = 2.0 metres. When multiplied by 3, this
results in a 6 ms time delay.
An additional 15 ms are added as a constant
to delay times determined in this way. For the
example given above, this results in: 6 ms + 15
ms constant = 21 ms delay time. As the CL 700/6
SWR permits settings in steps of 5, select the next
possible value, i.e. 20 ms.
