Delay (DLY)
The delay processor block, when inserted, provides a means to delay the audio signal.
Audio Delay is used to sync audio to video or to time-align speakers that are placed at
different distances from the listener. The DMP128 can set delay by either of two criteria:
time or distance (feet or meters).
The default unit setting is time with a range of 0.0ms 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 Enter, tabbing, or clicking away from the field.

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 time in 0.1 ms increments into the readout field.
Method Time Feet Meters
Click + drag 1 ms ~1.1 feet ~0.3 m
Focus + arrow 1 ms ~1.1 feet ~0.3 m
Focus + Page Up/Down 5 ms ~5.6 feet ~1.7 m
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: When using distance (feet or meters), set a temperature value first, then set
the distance.
