Sound Localization & Sound Image Control (Using Hass Effect)
Using the bus assign, the main PA sound can be positioned to match that of the sound
source. Delays in multiple speaker systems can be compensated using the bus output delays
(Hass Effect).
In a large or medium-sized church or hall with rear or side speakers, where the sound image
needs to direct listeners towards the presenter or sound source, adding a small delay of
between 10 and 20 milliseconds to the rear speakers gives the impression that the presenter
is actually located in front, not behind (Hass Effect). Each 03D output can be delayed by up
to 40 milliseconds.
To achieve the Hass Effect, a small delay must be used in addition to the delay used to
compensate for speaker distance. For example, if the distance between the front and rear
speakers is 30 meters, the speaker distance compensation delay will be 87 milliseconds
(30/344 = 0.087, where 344 is the speed of sound). To this a small delay of between 10 and
20 milliseconds should be added to achieve the Hass Effect.
Formula for setting total delay is
(distance between front and rear speakers/344) + 10–20 ms
