	To change the setting for any of the three
	speaker groups, press the ⁄/¤ Buttons
	n until the cursor is next to the line
	where you wish to make a change and
	then press the ‹/› Buttons o 37
	until the desired setting appears. The
	available choices at which point low-fre-
	quency information will be sent to the
	subwoofer, rather than to the main
	speaker channel, are 40Hz, 60Hz, 80Hz,
	100Hz, 120Hz and 200Hz. Pick the choice
	that is identical to the information for the
	speakers, or if an exact match is not pos-
	sible, pick the closest choice that is
	ABOVE the speaker’s low-frequency limit
	or crossover point to avoid the creation of
	a low-frequency “hole” where your sys-
	tem will have no bass information.
	In cases where LARGE has been
	selected as the front channel speaker
	option and LFE+L/R has been
	selected as the subwoofer option, the
	front channel sound information below
	the setting shown will be sent to BOTH
	the front channel speakers and the sub-
	woofer. Note, also, that when the
	LARGE-LFE+L/R setting has
	been selected, the crossover point
	defaults to 100Hz for both the front
	speakers and the subwoofer, and may not
	be adjusted. This ensures that there is no
	“hole” in the sound field due to different
	crossover points at the front and sub-
	woofer speakers.
	When all crossover settings have been
	made, or in those cases where none are
	needed, change the MODE setting to
	SIZE, and press the ¤ Button n
	so that the cursor is next to the
	BASS MGR line to make the final
	setting on this menu.
	This setting allows you to use the same
	speaker size settings for all inputs, or to
26	have different settings for each input. In

most cases the factory default setting of GLOBAL will be appropriate, as most listeners do not need to have individual- ized speaker settings. However, some lis- teners, may prefer different bass man- agement settings when listening to music through a CD player as opposed to a movie from a DVD player, VCR or cable/satellite set-top.

If you wish to customize the bass man- agement to each input, make certain that the MODE is set to SIZE, and that the cursor is on the BASS MGR line and press the ‹/› Buttons o 37 so that INDEPENDENT appears in highlighted video. When this setting is entered by exiting the menu, the configu- ration settings just entered will apply to the current input ONLY, and you will need to go back to the INPUT SETUP menu to select another input, and then return to this menu page again to change the settings for the next input. Repeat the procedure for any input where you wish to have a different set of speaker config- uration settings.

NOTE: The Independent feature allows you to select a different speaker size configuration (Large, Small or None, as appropriate) for each input source. However, the individual crossover point setting may only be set once, and the selection made during the initial setup will be used for all inputs, regardless of any changes made to the “Large” or “Small” settings for the speaker groups attached to any input. The reason for this is that while you may prefer different set- tings for the bass redirection (that is, which signals go to the subwoofer or the speaker group), the actual crossover point remains the same since the actual loud- speakers themselves remain the same regardless of any other setting.

When all speaker selections have been made, press the ¤ Button n and then the Set Button p to return to the

MASTER MENU.

Delay Settings

Due to the different distances between the listening position for the front chan- nel speakers and the surround speakers, the amount of time it takes for sound to reach your ears from the front versus sur- round speakers differs. You may compen- sate for this difference through the use of the delay settings to adjust the timing for the speaker placement and acoustics in your listening room or home theater.

The AVR580’s advanced software enables you to quickly and easily set delay times without the need to calculate them using a complex formula. Instead, all you need to do is measure the approximate dis- tance between your listening position and each of the speakers in your system. When you enter those distances into the AVR’s memory as shown below, the AVR’s microprocessor does the rest of the work, calculating the proper delay time. The measurements need not be accurate to the inch, as the system is designed to accommodate a typical listening area rather than require the precise measure- ment to one “sweet spot” position.

Due to the differences in the way each surround mode operates, some modes allow for a greater range of delay times than others. To avoid problems, we rec- ommend that delay times be adjusted using the Dolby Digital mode. If a differ- ent mode is selected at a later time, the AVR580 will automatically restrict the delay settings to those required by the surround mode in use.

Delay times are only adjustable for the Dolby modes, so you will notice that the DELAY ADJUST menu may not be accessed when any other mode, such as a DTS or Logic 7 option, has been selected. In addition, when a non-Dolby Digital mode such as Dolby 3 Stereo or Dolby Pro Logic II is selected, adjustments may be made to the Surround speakers only.

To set the delay time for a specific input, the DELAY ADJUST menu (Figure 7) should be visible on your on-screen dis- play. If the system is not already at that point, press the OSD Button v to bring up the MASTER MENU, press the ¤ Button n three times or until the on-screen › cursor is pointing at the DELAY ADJUST line. Press the Set Button p to call up the menu.
