Integra DTR-9.1 appendix Connecting speakers, Ideal speaker configuration, Speaker placement

Connecting speakers

Before connecting the speakers, place them correctly by consulting the instruction manuals that came with them.

For surround playback, the configuration and place- ment of your speakers are very important.

For THX surround EX playback, we recommend that you use a THX speaker system that is certified by Lucasfilm Ltd.

Ideal speaker configuration

•Front right and left speakers

•Center speaker

Produces a rich sound image by serving as a sound source for the front right and left speakers and en- hancing the sonic movement.

•Surround right and left speakers

Adds three-dimensional sonic movement and pro- duces environmental sound associated with the background and effect sound for each scene.

•Surround back right and left speakers Required for enjoying THX Surround EX audio.

•Subwoofer

Produces powerful and heavy bass.

Minimum speaker configuration for surround sound playback

•Front right and left speakers

•Surround right and left speakers

The sound recorded for the center speaker and the subwoofer will be properly distributed to the front right and left speakers and the surround right and left speakers for optimized surround playback.

Speaker placement

Ideal speaker placement varies depending on the size of your room and the wall coverings. Here, only typical example of speaker placement and recommenda- tions are shown.

Important points regarding speaker placement

Front left and right speakers and center speaker

•Place these three speakers at the same height from the floor.

•Place each speaker so that sound is aimed at the location of the listener’s ears when at the listening position.

Surround left and right speakers

•Place these speakers so that their height is 1 meter higher than that of the listener’s ears.

Surround back left and right speakers

•These speakers are required for enjoying THX Sur- round EX audio.

•Place these speakers behind the listener so that the angle between each speaker and the listener is ap- proximately 30 degrees.

•Place these speakers so that their height is 1 meter higher than that of the listener’s ears.

Most dipoles have an arrow on them to indicate their orientation towards the screen. So for the side dipoles, the arrows point forward. For the back dipoles, the ar- rows should point towards each other to achieve the correct acoustical phasing in the room.
