Delay (DLY)
The delay processor, when inserted, provides a means to delay the audio signal. Audio
delay syncs audio to video or can time-align speakers placed at different distances from
the listener. The DMP64 can set delay by either of two criteria: time or distance (feet or
meters).
The default units 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>, <Tab>, 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 directly 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 degrees Fahrenheit.
NOTE: When using distance (feet or meters), set a temperature value first, then set
the distance.
