Delay times can be specified by time in milliseconds, or distance in either Metres or Feet. This is set in the bottom left of the
window;-
The temperature can be set to match the ambient temperature at the venue and will compensate for the variations in speed of
sound through the air as temperature varies when distance has been selected. The temperature adjustment does not affect
delay times when Time has been selected as the unit of display. The temperature is selected from a drop-down list from -20 to
+40⁰C. You may wish to consider cancelling any sho ws where the ambient temperature is - 20⁰C; ticket sales are likely to be
poor...
The other option available is the step size selected from the box just above the units selection;-
As well as entering an absolute value, any selected delay may be stepped up or down using the ‘UP’ or ‘DOWN’ buttons. This is
particularly useful when time aligning systems by ear, perhaps using an audible click, the delay can be gradually adjusted until
the clicks are perfectly in sync. Step size can be selected from the drop-down and can be 0.01, 0.1, 1.0, 10.0 or 100.0 milliseconds.
The delay window displays the entire routing matrix and input and output channel names so it is easy to see where delays need
to be applied. The input and output sections are broadly similar, first here is an input channel;-
