English SYSTEM SETUP SUBWOOFER FRONT LEFT CENTER FRONT RIGHT Receiver adjustment Once the number and position of loudspeakers has been fixed, you can adjust the initial receiver settings for optimal surround sound with the actual setup: SURROUND (REAR) LEFT SURROUND (REAR) RIGHT Positioning the speakers General hints for positioning Avoid positioning the speakers in a corner or on the floor as this will boost the bass tones too much. Placing the speakers behind curtains, furniture, etc. will reduce the treble response. The listener should always be able to "see" the speakers. Each room has different acoustic characteristics and the positioning possibilities often are limited. You can find the best position for your speakers by referring to the picture above. As a minimum we recommend 5 speakers (2 front, a center, 2 surround) for good surround sound. It is possible to reproduce some kind of surround sound with fewer speakers. This is done by redirecting the signals which are foreseen for the missing speakers to the existing ones. See "Menus" on how to set up the receiver correctly for the number and size of the speakers used. Positioning the front speakers The front speakers should be placed to the right and left in front of the listening position like usual stereo speakers. Positioning the center speaker The center speaker should be placed in the center between the two front speakers, e. g. underneath or on top of the TV. The best height for the center speaker is the height of the listener's ears (while seated). 1 Set which speakers have been connected to the receiver (see "Menu structure/* SPEAKR SETUP"). Note: The initial setting of your receiver is: two front speakers left and right: present (cannot be altered) center speaker: present two rear speakers: present subwoofer: present. 2 Select the size of the speakers (SMALL or LARGE) (see "Menu structure/* SPEAKR SIZES"). Select SMALL if your speaker is able to reproduce low notes down to at least 80-100 Hz. Select LARGE if your speaker is able to reproduce low notes down to at least 50 Hz. (As a rule of thumb, a LARGE speaker has a cone diameter of at least 12 cms (5 inches).) See the specification sheets of your loudspeakers. 3 Set the distance from the speakers to the listener's position (see "Menu structure/* SPK DISTANCE"). Note: If you prefer that your receiver does not correct automatically for speaker sizes and distances, you can re-progam it to a neutral setting by - installing all speakers: (Subwoofer present, Center and Rear loudspeakers: all YES), - setting Front, Center and Rear speaker sizes to LARGE, - setting all loudspeaker distances (L/R, Center and Rear) to the same distance (e.g. 10 ft). Positioning the surround speakers The surround speakers should face each other and be in line with, or slightly behind the listener. Positioning the subwoofer A subwoofer can be used to enhance the bass performance of your system dramatically. The subwoofer can be positioned anywhere in the room, because it is not possible to locate the source of deep tones. Nevertheless, you should not place the subwoofer in the middle of a room, since the bass could be severely weakened. Do not place any object on the subwoofer. 14
