Application Information

DISTANCE MODE

There’s more than one way to view your time setting. If you’re

tired of looking at milliseconds, the delay setting can also be

viewed in terms relative to distance by changing the displayed

units to feet or meters and by selecting the ambient temperature

in either °C or °F. The AD22S calculates the precise environmen-

tal delay by using the relationship of air pressure and tempera-

ture to the speed of sound.

VIDEO MODE

The AD22S is an effective solution to the problem of aligning

audio with video in broadcast. Because of the latency involved in

processing video streams, timing offset accumulates that can run

as high as several frames or lead to noticeable synchronization

issues. While in Video mode, the AD22S displays the delay time

in the precise number of frames calculated for your current for-

mat and frame rate. You may choose from a selection of the most

common frame rates to match your work situation and environ-

ment. As you adjust the number of frames needed to synchronize

the audio, the AD22S calculates the delay to match exactly what

you need.

REMOTE RECALL

In some situations it may be necessary to recall a stored setting

or enable channel bypass from a location other than where the

AD22S is located. Have a room divider wall? You can install a

switch to select between the two room settings automatically

when the wall is moved. Does the delay for your outdoor speaker

array change with the temperature? Wire up a switch to change

from a memory setting adjusted for one temperature to one saved

for the other when the weather warms up. For these reasons we

have provided remote recall connections on the rear of the unit

that can be wired to standard switches installed in any other

location.
