[. . . ] As the main plug is used to disconnect the unit from the mains, connect the unit to an easily accessible AC outlet. Should you notice an abnormality in the unit, disconnect the main plug from the AC outlet immediately. Do not expose batteries or apparatus with batteryinstalled to excessive heat such as sunshine, fire or the like. The unit is not disconnected from the mains as long as it is connected to the AC outlet, even if the unit itself has been turned off. [. . . ] · SINGLE If you connect only one surround back speaker, select "SINGLE". The sound will be output to a maximum of 6. 1 channel. · DUAL If you connect two surround back speakers, select "DUAL". The sound will be output to a maximum of 7. 1 channel. Tip The "LARGE" and "SMALL" settings for each speaker determine whether the internal sound processor will cut the bass signal from that channel. When the bass is cut from a channel, the bass redirection circuitry sends the corresponding bass frequencies to the subwoofer or other "LARGE" speakers. However, since bass sounds have a certain amount of directionality, it is best not to cut them, if possible. Therefore, even when using small speakers, you can set them to "LARGE" if you want to output the bass frequencies from that speaker. On the other hand, if you are using a large speaker, but prefer not to have bass frequencies output from that speaker, set it to "SMALL". If the overall sound level is lower than you prefer, set all speakers to "LARGE". If there is not enough bass, you can use the equalizer to boost the bass levels. b) You can only select this parameter when the surround back speakers are set to "DUAL" in SYSTEM menu. 52GB x SUR POS. (Surround speaker position) Lets you specify the location of your surround speakers for proper implementation of the surround effects in the CINEMA STUDIO EX modes (page 58). This setup item is not available when the surround speakers are set to "NO" (page 42). Tip Surround speaker position is designed specifically for implementation of the CINEMA STUDIO EX modes. For other sound fields, speaker position is not so critical. Those sound fields were designed under the premise that the surround speakers would be located behind the listening position, but presentation remains fairly consistent even with the surround speakers positioned at a rather wide angle. However, if the speakers are pointing toward the listener from the immediate left and right of the listening position, the surround effects become unclear unless set to "SIDE/LO" or "SIDE/HI". Nevertheless, each listening environment has many variables, such as wall reflections, and you may obtain better results using "BEHD/HI" if your speakers are located high above the listening position, even if they are located to the immediate left and right. Therefore, although it may result in a setting contrary to the above explanation, we recommend that you play back multi channel surround encoded software and select the setting that provides a good sense of spaciousness and that best succeeds in forming a cohesive space between the surround sound from the surround speakers and the sound of the front speakers. If you are not sure which sounds best, select "BEHD/LO" or "BEHD/HI" and then use the speaker distance parameter and speaker level adjustments to obtain proper balance. Amplifier Operations x CRS. FREQ (Speaker crossover frequency) Lets you set the bass crossover frequency of the speakers that have been set to "SMALL" on the SYSTEM menu. This setup item is only available when at least one speaker is set to "SMALL" and the corresponding speaker indicator flashes on the display. · BEHD/HI Select if the location of your surround speakers corresponds to sections B and D.
