CONNECTIONS CONNECTIONS Placing speakers The speaker layout below shows the standard ITU-R* speaker setting. You can use it to enjoy CINEMA DSP and multi-channel audio sources. * ITU-R is the radio communication sector of the ITU (International Telecommunication Union). PL PR C FL FR 30˚ SL 60˚ SL 80˚ SBL SR SR SBR 30 cm (12 in) or more PR PL FR FL C SL SW SR SBR SBL 1.8 m (6 ft) Front left and right speakers (FL and FR) The front speakers are used for the main source sound plus effect sounds. Place these speakers at an equal distance from the ideal listening position. The distance of each speaker from each side of the video monitor should be the same. Center speaker (C) The center speaker is for the center channel sounds (dialog, vocals, etc.). If for some reason it is not practical to use a center speaker, you can do without it. Best results, however, are obtained with the full system. Place the center speaker centrally between the front speakers and as close to the monitor as possible, such as directly over or under it. Surround left and right speakers (SL and SR) The surround speakers are used for effect and surround sounds. Place these speakers behind your listening position, facing slightly inwards, about 1.8 m (6 ft) above the floor. Surround back left and right speakers (SBL and SBR) The surround back speakers supplement the surround speakers and provides more realistic front-to-back transitions. Place these speakers directly behind the listening position and at the same height as the surround speakers. They should be positioned at least 30 cm (12 in) apart. Ideally, they should be positioned at the same width as that of the front speakers. Presence left and right speakers (PL and PR) The presence speakers supplement the sound from the front speakers with extra ambient effects produced by CINEMA DSP (see page 71). These effects include sounds that filmmakers intent to locate a little farther back behind the screen in order to create more theater-like ambience. Place these speakers at the front of the room about 0.5 - 1 m (1 - 3 ft) outside the front speakers, facing slightly inward, and about 1.8 m (6 ft) above the floor. Subwoofer (SW) The use of a subwoofer with a built-in amplifier, such as the YAMAHA Active Servo Processing Subwoofer System, is effective not only for reinforcing bass frequencies from any or all channels, but also for hi-fi stereo sound reproduction of the LFE (low-frequency effect) channel included in Dolby Digital and DTS sources. The position of the subwoofer is not so critical, because low bass sounds are not highly directional. But it is better to place the subwoofer near the front speakers. Turn it slightly toward the center of the room to reduce wall reflections. 12
