6.3 Display Delay Options
The units of measurement used to specify the delay on the input and output channels can be set as time
or distance to suit user preference, as follows:
• Time (milliseconds and microseconds).
• Metric distance (metres).
• Imperial distance (feet and inches).
To change the units of measurement
1 From the ELGAR menu, select select Tools > Options > DN9848E.
2 In the System Configuration window, select DN9848 from
the Devices option. If necessary, click on
to the
left of Devices to show the DN9848 option.
3 Select the display delay you
require from the Display Delays
drop-down menu, for example,
“Imperial (inches)”.
4 If you selected Metric or Imperial distance measurement,
specify the ambient temperature (in degrees centigrade) of
the venue using the Default Unit Temperature control knob, for
example, “23C” for 23°C. The HELIX DN9848E will use this
to adjust the speed of sound, which varies with
temperature, in the delay calculation so that accurate
delays are applied to the channels.
5 Click OK to select.
The delay units in the input and output menus change to the new selection and their values are
automatically converted accordingly.
