Large Small No

≥Large: Select when the speaker supports low-frequency (under 100 Hz) reproduction.

≥Small: Select when the speaker does not support low-frequency reproduction.

In order to make an ideal listening environment, settings of speaker sizes may be automatically adjusted.

For example, if the subwoofer is set to “No”, the front speakers will automatically be set to “Large”. (In this case, we recommend connecting a speaker that can reproduce bass below 100 Hz.)

Delay time ( ms )

For optimum listening with 7.1/5.1-channel sound, all the speakers, except for the subwoofer, should be the same distance from the seating position.

If you have to place the center, surround and surround back speakers closer to the seating position, adjust the delay time to make up for the difference.

If either distance A or C is less than B (D below), find the difference in the relevant table and change to the recommended setting.
