Delay - Extron electronics DMP 64 User Manual

Delay

Audio Delay is used to sync audio to video or to time-align speakers that are placed at
different distances from the listener. The DMP 64 can set delay by one of three criteria:
time, feet, or meters. The default unit setting is time with a range of 0.0 ms to 200.0 ms
adjustable in 0.1 ms steps. Default is 100.0 ms.
Settings are controlled with a vertical slider and indicated with a value readout field. The
value can be changed by clicking within the readout field, changing the number, then
either pressing
Figure 25.
Slider adjustments made in feet or meters correspond incrementally to the distance
required to make 1 ms, or 5 ms adjustments (detailed in the table below). If more
precision is required, enter the time in 0.1 ms increments into the readout field.
Method
Click + drag
Focus + arrow
Focus + Page Up/Down
When distance (feet or meters) is chosen, the conditions (temperature) field becomes
available and can be set either by degrees Fahrenheit or Celsius. When entering a
distance, time delay compensation is automatically modified based on differences in the
speed of sound due to air temperature.
Default is 70° Fahrenheit.
NOTE: Set a temperature value first, then set the distance.
Enter or tabbing/clicking away from the field.
