User manual SONY XS-GF1621X DATASHEET

[. . . ] The surround back speaker (in SCS 188 only) should be placed behind the listening position, facing the center speaker. The surround speakers should not call attention to themselves. Experiment with their placement until you hear a diffuse, ambient sound accompanying the main program material heard in the front speakers. The low-frequency material reproduced by the subwoofer is mostly omnidirectional, and this speaker may be placed in a convenient location in the room. However, the best reproduction of bass will be heard when the subwoofer is placed in a corner along the same wall as the front speakers. [. . . ] Place the subwoofer in that location. 3 MOUNTING OPTIONS Satellites and Surrounds On shelves. On the wall. Wall brackets are included. On optional stands. Wall-Mounting The customer is responsible for proper selection and use of mounting hardware, available through hardware stores, to properly and safely wall-mount the speakers. SPEAKER CONNECTIONS Connection Tips Separate and strip the ends of the speaker wire as shown. Speakers and electronics terminals have corresponding (+) and (­) terminals. Most manufacturers of speakers and electronics, including SONY, use red to denote the (+) terminal and black for the (­) terminal. The (+) lead of the speaker wire is noted with a stripe. It is important to connect all speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. With the advent of multichannel surround-sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material. 4 Dolby* Pro Logic* (Non-Digital) ­ Speaker Level (XS-GF1621X only) Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS® or other digital processing), where the receiver/processor does not have a subwoofer output, or a volume-controlled preamp (line-) level output: Connect your receiver or amplifier's front left and right speaker terminals to the left and right terminals on the subwoofer that are marked "High Level In. " Connect the left and right terminals on the subwoofer that are marked "High Level Out" to the corresponding terminals on the back of your front left and right speakers. Connect your receiver or amplifier's center, left and right surround-speaker terminals to the corresponding terminals on the back of your center, left and right surround speakers.

IMPORTANT: Do not use the LFE input on the subwoofer with Dolby Pro Logic processors. Note: If your receiver or amplifier only has one subwoofer output jack, then you will need to use a Yconnector (not included). · Check all wires and connections between receiver/ amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured. · Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker: · Check the "Balance" control on your receiver/amplifier. · Check all wires and connections between receiver/ amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured. · In Dolby Digital or DTS® modes, make sure that the receiver/processor is configured so that the speaker in question is enabled. If there is no sound from the center speaker: · Check all wires and connections between receiver/ amplifier and speaker. Make sure none of the speaker wires are frayed, cut or punctured. · If your receiver/processor is set in Dolby Pro Logic mode, make sure the center speaker is not in phantom mode. · If your receiver/processor is set in Dolby Digital or DTS® mode, make sure the receiver/processor is configured so that the center speaker is enabled. [. . . ] If the system plays at low volumes but shuts off as volume is increased: · Check all wires and connections between receiver/ amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low (or no) bass output: · Make sure the connections to the left and right "Speaker Inputs" have the correct polarity (+ and ­). [. . . ]
