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 DMP 64 can set delay by either of two criteria: time or distance (feet or meters).

The default units setting is time with a range of 0.0 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 <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.
