OPERATORS MANUAL AD22S

AUDIO DELAY

QUICK START

Your AD22S is out of its box, and now it’s time to integrate it

with your audio setup. But wait! What are these buttons for?

What do all those numbers on the display mean? is guide in-

tends to help you quickly learn the basics and familiarize you with

the device so there’s no delay before you delay.

FRONT PANEL CONTROLS

e rst thing to decide is which alignment mode to use. If you’re

using the AD22S to synchronize audio with video, then select

Video mode. Otherwise select Distance alignment. e DIS-

TANCE and VIDEO buttons on the left hand side of the unit

switch between the two modes. Display settings and delay values

are controlled by using the CHANNEL button to toggle between

channels 1 or 2, and by using the CURSOR buttons to select

the value you wish to change. e COARSE and FINE buttons

increment or decrement the value currently selected.

DISTANCE ALIGNMENT

One of the main applications for the AD22S is synchronizing

an audio signal coming from separate sources at two dierent

distances. Say, for example, you want the music emanating from

a stack of loudspeakers on the lawn at an amphitheater to get to

your audience at exactly the same time as sound coming from

the speaker arrays on stage. e amount of delay needed is the

time it takes sound to travel from the stage to the lawn. While in

DISTANCE mode, this can be displayed in feet, meters, or mil-

liseconds.

VIDEO ALIGNMENT

e AD22S is also excellent for synchronizing audio with video

feeds, especially in a live environment where video processing

typically adds several milliseconds to the signal that can have a

noticeable eect on the nal output. To assist in this application,

the AD22S can show your delay value directly in terms of frames.

All common frame rates for NTSC and PAL/SECAM are sup-

ported, and the audio stream can be delayed with a precision of

0.5 frames to line up perfectly with any video stream.

WEAR PARTS: is product contains no wear parts.

SETTING DELAY

Use the  CURSOR  buttons to select the unit type, then

press the COARSE or FINE buttons to cycle through options. In

Distance mode, choose between feet, meters, or milliseconds; in

Video mode the delay is shown in frames or milliseconds. If you

know the distance between the sources you are summing, set the

units for feet or meters.

e ambient temperature also aects the speed of sound. To

set the temperature, use the CURSOR buttons to select either °C

or °F, then set the value to the approximate temperature at your

speaker location. e AD22S calculates the correct delay based on

your environment.

Note: Changing units from distance to time does not change

the output delay. For example, if you are viewing the settings for

channel 1 in meters, a change from meters to milliseconds keeps

the same amount of delay but shows it in milliseconds rather than

distance.

LINKING CHANNELS

e LINK button connects the controls so that all changes apply

to both channels. Channels do not need to share the same setting.

While linked, incrementing or decrementing a value changes the

delay for both channels at once. To treat the channels as a stereo

pair, rst set the delay value to the same setting on both channels

before pressing the LINK button.

MEMORY FUNCTIONS

Each channel has two memory banks, A and B. e * character

at the right of the display indicates that the current setting does

not match what is stored in memory.

Pressing STORE copies the current settings into the selected

Memory, clearing the * character. e cursor must be over the

Memory Bank eld before pressing STORE. To activate a stored

setting, press RECALL to change the active delay to the value

stored in the memory location shown. If channels are linked, both

will be recalled.
