[. . . ] If both front speakers are not placed an equal distance from your listening position, set the distance as the average distance between the front speakers. Lets you set the distance from your listening position to the center speaker. Center speaker distance should be set from a distance equal to the front speaker distance (A) to a distance 1. 5 meters (5 feet) closer to your listening position (B). Lets you set the distance from your listening position to the surround left speaker. Surround left speaker distance should be set from a distance equal to the front speaker distance (A) to a distance 4. 5 meters (15 feet) closer to your listening position (C). However, it is not possible to set the center speaker further than the front speakers. Also, the center speaker cannot be set more than 1. 5 meter (5 feet) closer from the front speakers. Likewise, the surround speakers can not be set further away from the listening position than the front speakers. This is because incorrect speaker placement is not conducive to the enjoyment of surround sound. Please note that, setting the speaker distance closer than the actual location of the speakers will cause a delay in the output of the sound from that speaker. In other words, the speaker will sound like it is further away. For example, setting the center speaker distance 1-2 meter (3-6 feet) closer than the actual speaker position will create a fairly realistic sensation of being "inside" the screen. If you cannot obtain a satisfactory surround effect because the surround speakers are too close, setting the surround speaker distance closer (shorter) than the actual distance will create a larger sound stage. Adjusting these parameter while listening to the sound often results in much better surround sound. Lets you set the distance from your listening position to the surround right speaker. Surround right speaker distance should be set from a distance equal to the front speaker distance (A) to a distance 4. 5 meters (15 feet) closer to your listening position (D).

Surround back speaker distance should be set from a distance equal to the front speaker distance (A) to a distance 4. [. . . ] If so, the service may be temporarily out of order.
