3.6. Input & Output Delay
The following Icon in the input path is the one dealing with Delay. (The same Icon can be found in the
output paths.) This Icon opens the following "Input & Output Delays" window:
Here the general delay for channels A, B and M can be adjusted. Three faders allow the
adjustment of the different input delays. When adjusting any of them, the delay value expressed in
both metres and milliseconds will appear below the corresponding fader.
A precise adjustment of the delays is achieved by selecting the corresponding fader by clicking on it
with the mouse, and then using the cursor left and right keys on your computer keyboard. This method
allows adjustment in steps of 1cm.
If the box Link A to B is activated, the delay times for channels A and B will be set to equal values and
if you adjust any one of them the other one will perform in the same way. If the Link A-B-M is
activated, all the input delay times will be identical. On returning to the main screen, the delay time
value you have entered will appear below the corresponding delay button in the signal path.
The Temperature function allows you to enter the approximate environmental operating temperature
(Fahrenheit/Celsius) which calculates the speed of sound to be as precise as possible.
Each input delay is adjustable up to 100 meters (291.23 milliseconds at 20ºC). These delays can be
used in a main delay line situation where extra audio reinforcement systems are placed at great
distances to the main PA system.
There is also a delay Icon in the output paths. The following window allows the configuration of the
output delays:
Here 4 faders allow the delay time adjustment of the 4 output channels. Here the values are shown in
centimetres and milliseconds.
