opus THE HOME THEATRE ENVIRONMENT Front and Effects Channels The front loudspeakers are placed on either side of the television screen, 2 to 3 metres apart. The speakers should be angled slightly so they are aimed towards the listeners. As the rear surround channels are the ‘effects’ channels the reproduced sound should be as room filling as possible. We recommend placing the speakers in a high position, behind the listeners head. If the rear wall is more than 1 metre behind the listening seat,

The purpose of delay is to enable surround and dialogue information to arrive at the listener’s ears at the same time as the front channels, even when the listen- ing seat is in a non-ideal position. On some processors, this can be achieved by setting the distance from the listening position to each speaker in turn, but other systems allow only a time delay setting.
