NEDERLANDS DEUTSCH ITALIANO ESPAÑOL FRANÇAIS ENGLISH OPERATION USINGTHET775­SETUPMENU ENGLISH FRANÇAIS ESPAÑOL LARGE SPEAKER CONFIGURATION Every surround-sound system requires "bass-management" to direct low-frequency content from any or all channels to the speakers best able to reproduce it. For this function to operate correctly, it is important that you correctly identify your speakers' capabilities. We use the terms "Small" and "Large" (and "Off") but note that physical size may be irrelevant. · A "Small" speaker is any model, regardless of physical size, that lacks significant deep-bass response, that is, below about 80 Hz. · A "Large" speaker is any full-range model; that is, one with deep-bass response · An "Off" speaker is one that is not present in your system. For example, you might not have any surround-back speakers installed; in that case, you would set the `Surround' setup item to "Off". Depending on the relationship between speakers, the possible selections for each speaker are as follows: Front L/R Center Surround L/R LARGE LARGE SMALL OFF LARGE SMALL SMALL OFF LARGE OFF SMALL OFF SMALL SMALL OFF SMALL OFF SMALL OFF Back LARGE SMALL OFF LARGE SMALL OFF OFF LARGE SMALL OFF LARGE SMALL OFF OFF LARGE SMALL OFF LARGE SMALL OFF OFF SMALL OFF OFF SMALL OFF OFF Subwoofer 1/2 ON or OFF ITALIANO DEUTSCH NEDERLANDS SVENSKA ON The Speaker Configuration is "global"; that is, it remains in force with all inputs and in all listening modes. However, speaker settings are part of the T 775's Preset system. Consequently, multiple speaker settings can be stored for easy recall as different types of recordings or listening modes require. Speaker Configuration can be managed and adjusted by pressing a combination of and then keys. Set `Front, ' `Center, ' and `Surround' to "Large, " "Small" or "Off" as your subsystem's speakers require. The `Back' speakers can either be one or two speakers. Set `Back' to either 1 or 2 speakers as per availability. Set `Subwoofer' to "On" or "Off, " selecting "On" only if you have a subwoofer connected to the T 775's SUBW1 or SUBW2 output jack. OPERATION USINGTHET775­SETUPMENU ENHANCEDBASS When the subwoofer is set to ON and one or more speakers are set to "Large", Enhanced Bass is also available. Normally, with speakers set to "Large" the subwoofer is not active. The Enhanced Bass option allows full range operation of the speakers with the additional bass contribution of the subwoofer. This feature is particularly useful when one wants to experience maximum bass output. Please note that due to acoustic cancellation effects, the bass response may be uneven when using this setting You can set Subwoofer to "On" even with "Large" front speakers, in which case bass content from any channels set to "Small" will be routed to both the subwoofer and to the front speakers; LFE-channel signal will pass only to the sub.
