[. . . ] Troubleshooting - You must unplug your device from the Power supply and have it checked by a qualified technician if: The power supply or the plug is damaged. The device does not seem to work correctly under normal operating conditions. Only operate the controls described in this manual. Any other operation could damage the device and require on-site visit of a qualified technician. [. . . ] Theoretically, the screen should be located within a virtual triangle formed by the acoustical centres of the main speakers and the centre speaker. Practically speaking, this means that the principal speaker should be placed above the screen if the main speakers are below it, and below the screen if the main speakers are above. The centre speaker should also, if possible, be set slightly back from the others, so that it is located at the same distance from the listener as the main speakers. The rear speakers or surround should be placed against the side walls, at listening height. They should not be positioned far behind the listening zone. The subwoofer should be placed in the front listening area, its position against a wall reinforces the extreme low register and limits the reflections between 80 and 200 Hz. However to obtain the best result, it is always necessary to carry out tests according to the acoustics of the room. Your AV processor enables the adjustment in level and delay of each of the 5/6/7 channels of your system. Fine-tuning is necessary to obtain a perfect sound stage. In addition to vertical position of the speakers themselves, their location in the listening room, as well as the acoustical characteristics of the room, are also very important. As it is impossible to indicate a typical location of speaker systems without a few tests, we suggest several general rules that are important to apply in order to obtain the best listening results. For the ideal positioning of your speakers follow diagram. If «d» is the distance between the two speakers, this distance must be higher than 5 ft (1. 5 m) and the two speakers must be at equal distance from the listening area which forms with them an equilateral triangle. The drivers must be directed towards the listening area. The speakers should be located so that their diffusion follows the longest dimension of the room. Generally speaking it is better to avoid putting the speakers in the corners of a room as this amplifies the low frequencies and tends to enhance the room resonances. If possible it is better to place the speakers at least 8 inches (20 cm) from the walls. Moreover, in order to obtain a more accurate frequency response, it is recommended to raise a compact speaker from 12 to 16 inches (30 to 40 cm) above the floor by placing them on stands. The tweeters of the speakers must be roughly at the same height of the listener's ear when the listener is in sitting position. No solid object or piece of furniture should be placed between the speakers and the listener. An effect of mask, even partial disturbs completely the sound reproduction as it attenuates the high frequencies and also, in most cases, the midrange frequencies. [. . . ] Connections TO SPEAKERS0 plugs These outputs can be used to bring the signal to the main loudspeaker systems. The signal from the L (left) and R (right) TO SPEAKERS0 plugs is the one being brought in by the FROM RECEIVER9 connectors. These outputs can thus be used to bring the signal to the main loudspeaker systems. With the switch on the STAND BY position, the unit will mute after a few minutes without input signal. [. . . ]
