The quick and easy way to set delays is to measure the distance in feet (either with a long tape measure or laser range finder) and multiply by .885, which will give you the delay time in milliseconds. The general rule is 88.5 ms. per 100 ft. Bear in mind that you can only set perfect delay for one seat in the house: if you move 3 ft. to the side the path-lengths and therefore the delay times will be different.

The simplest solution is to estimate or walk off the distance in feet and add that many milliseconds. Listen and adjust as needed.
Or you can be really pro about it and go down to Home Depot and buy a cheap laser tape measure and just measure the distance then inout that into the AudioTools app to convert to ms of delay.

Or if you work in metric, 29mS per metre.

And add a few milliseconds to give the perception of the sound coming from the stage.

Just to elaborate on what Steve mentioned: Precedence effect (Haas effect)

and was asking about setting delay times for distributed speakers.
Just to "clarify", are you talking about mains and delays or a distributed speaker system?

Those are very different things.

As a general rule, trying to set delays for a distributed downfiring system is an exercise in futility.

Sure you can get a couple of areas "right", but you have just as many that are wrong.

Is suspect this type of system is not what you are referring to, but is what is commonly know as a "distributed" system.

A buddy of mine does DJ gigs and social events and was asking about setting delay times for distributed speakers. He is not going to buy and learn smaart. Is there a phone app for this? He has the ability to set delays, he just needs help in determining the correct timing.
I told him to get a simple digital metronome device to use as a source. Any tricks to share?

Maybe buy a used Behringer DCX 2496...does delay automatically in one of its functions?
