[. . . ] Placing the loudspeakers in corners or against a wall will result in the strongest (not necessarily the most accurate) bass. Since the GHE Series are ported on the front panel so you can place the rear of the speaker up against a wall if desired. PLACEMENT The GHE Series cabinet height and driver placement allow for speaker placement directly on the floor. The video shielding allows for the option of placement very close to a video monitor/TV. When used as Left and Right Channel speakers in a Dolby Pro Logic AV system, the shielding allows the speakers to be placed up against the sides of the monitor/TV for a compact AV system profile (see Fig. [. . . ] For each channel, the red terminal on the loudspeaker should be connected to the red or (+) loudspeaker connection terminal on the receiver or amplifier, and the black to the black or (­) speaker conection terminal (see Fig. Connecting the loudspeakers in this manner ensures that they will be in phase; that is, work together rather than in opposition. Connecting the loudspeakers out of phase will not damage them, but will result in less bass and poor imaging. Left Speaker Red Blk. (+) (­) +L+R Amplifier/Receiver Fig. 3 Hooking Up Multiple Sets of Speakers If your receiver has two complete sets of speaker terminals ("A" and "B"), it's possible to hook up an additional pair of speakers for simultaneous sound in another room. However, some speakers may not be usable as a second pair if you want to play two sets at once. Before hooking up another set of speakers besides your GHE Series, check the following: 1. Your receiver or amplifier minimum load impedance. Impedance is always expressed in ohms and can be found in the owner's manual that came with your unit. For example, the following are typical entries in receiver/amplifier owner's manuals: A)100 watts RMS into 8 ohms, both channels driven, 20­20kHz with less than 0. 02% THD. B) 160 watts RMS into 4 ohms, both channels driven, 20­20kHz with less than 0. 02% THD. The nominal impedance of the second set of speakers. NEVER CONNECT TWO AMPLIFIER CHANNELS TO THE SAME LOUDSPEAKER WITHOUT FIRST REMOVING THE STRAPPING BARS. Operating two amplifier channels with the GHE strapping bars in place can seriously damage the amplifiers!If your preamplifier has just one set of stereo outputs, you will need to use "Y" cords in the two, three, and four-amp biwire hook-ups. "Y" cords are available from many sources including your SONY dealer. If you have hooked up your GHEs in any of the bi-wire configurations indicated, it is not advisable to use additional speakers, either separately or simultaneously. As with conventional one-amplifier, non-bi-wire conections shown in the "CONNECTIONS" section of this manual, make sure that all speaker cables are the same length and that you maintain the "red-to-red" and "black-to-black" connections between the amps and the speakers.

[. . . ] Do not use any cleaners or solvents on the speaker drivers themselves. TROUBLESHOOTING The vast majority of new speaker "malfunctions" end up being traced to connections or switch settings. To avoid packing up correctly functioning speakers and sending them off, only to find that they're not really at fault, check the following tips first, before requesting service. No sound at all or very faint sound from both speakers 1. Amp/receiver tape monitor button pushed in while using CD, FM or phono inputs. Wrong speaker switch, "A" or "B" speaker output. [. . . ]
