[. . . ] To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. To prevent fire, do not cover the ventilation of the apparatus with news papers, table-cloths, curtains, etc. and don't place lighted candles on the apparatus. To prevent fire or shock hazard, do not place objects filled with liquids, such as vases, on the apparatus. [. . . ] 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 (page 75). When the front speakers are set to "SMALL, " the center, surround, and surround back speakers are also automatically set to "SMALL. " · If you do not use the sub woofer, the front speakers are automatically set to "LARGE. Lets you specify the location of your surround speakers for proper implementation of the surround effects in the Cinema Studio EX modes (page 62). This setup item is not available when there are no surround speakers. LARGE If you connect large speakers that will effectively reproduce bass frequencies, select "LARGE. SMALL If the sound is distorted, or you feel a lack of surround effects when using multi-channel surround sound, select "SMALL" to activate the bass redirection circuitry and output the bass frequencies of each channel from the sub woofer or other "LARGE" speakers. 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 sub woofer or other "LARGE" speakers. However, since bass sound has a certain amount of directionality, it is best not to cut them, if possible. Therefore, even when using small speakers, you 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. " Nevertheless, each listening environment has many variables, such as wall reflections, and you may obtain better results using "BEHD" 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 playback 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" and then use the speaker distance parameter and speaker level adjustments to obtain proper balance. Selects the pattern number according to the number of the using speakers. Lets you output the test tone sequentially from each speaker. FIX You can select which speakers will output the test tone. ON Lets you output front 2 channel source sound (instead of the test tone) sequentially from adjacent speakers. [. . . ] To prevent a gas explosion, do not connect the ground (earth) wire to a gas pipe. The signal strength of the stations is too weak (when tuning in with automatic tuning). Make sure you set the tuning interval correctly (when tuning in AM stations with direct tuning). Make sure that you are tuned to an FM RDS station. [. . . ]
