The delay page lets you adjust delay by
Time
or
Distance
. Distance can be measured in either CM or
INCH units. Simply clicking the measurement unit at the top of the column changes it to the other unit.
To set the delay and make it appear that all speakers are the same distance from you:
a. Measure the distance between each speaker and where your ears will be in the actual listening position.
b. Identify the farthest speaker.
c. Add distance to each of the other speaker so that ALL speakers have the same distance. You do this
by subtracting each of the shorter speaker distances from the longest. (See Example Below).
Here we show delay for an 8-channel system, but the method is the same for any number of channels.
In this example, the longest speaker distance is 70” so we subtract each of the other speakers from 70
and enter the results in the Delay Page. As you put in each speaker in centemeters or inches and hit
Enter, the program will change the number to round to the nearest .01 ms.
The delay page also allows you to set up three
Delay Groups
, so you are able to move the apparent
position of a group of speakers in relation to the rest of the system. i.e. you may want to move the rear
fill farther back from the front stage to make the room sound larger.
After the delays are set, the information will be transferred to the Main page so there is a reminder of
both delay and group positions while fine tuning the system.
Delay and phase are intimately related. Changing the polarity of a pair of speakers changes the apparent
distance, especially in the bass regions where the wave lengths are long. It also changes the phase
relationship between different speaker pairs at the crossover point. The delay page has buttons to
change the polarity of each channel if needed. On page 34 of this manual you will find a procedure for
setting polarity of the speakers.
You should perform the system phasing (Polarity Check) after the crossovers are set and before any
equalization is attempted because if polarities ar not correct there will be issues that can not be overcome
through tuning.
