PLACING THE MONITORS

This manual section is split into two. The first part is a direct guide on how to optimize your listening facilities to ensure optimal performance of your AIR monitor system. The second part contains In Depth explanations and background information of various acoustic phenomena and is referred to on several occasions in the first chapter. To dive into this chapter and start optimizing your setup, it is essential that you have made proper connections for your AIR System. Please follow the illustrations in the “setups” section on pages 7 to 13.

In general: Symmetry

Basically it is preferred to establish a loudspeaker layout that provides an adequate and equal left/right image. The basis for this symmetry, meaning that the distance to the left and the right monitors is identical, and if not monitoring in the near field, then having identical distance to the (identical) side-walls.

The AIR System offer tools for compensation, but symmetry should be established whenever possible.

Front monitors, left & right

For a proper stereo monitoring the monitors should be placed at an angle of ±30º in front of the listening position. This goes both for a basic stereo setup and for the L&R front monitors in a 4 or 5 channel setup.

Center front monitor

ITU 775

The center front loudspeaker can be placed either: A: in the middle and in the same distance from

the listening position as the left and right front monitors or

B: in the middle and on a straight line between the left and right front monitors.

Surround monitors, left and right

The surround monitors should be placed at an angle of ±110 (+/-10) and in the same distance from the listening position as the Left & Right front monitors. Read more on the following pages.

1)If you want to fulfill the requirements of the standard ITU 775, you should either use the A-solution or the B-solution along with a Delay on the center monitor in order to achieve the same time of arrival from all monitors. Delay-time for each monitor can be adjusted using the AIR PC-IP Installers software.
