System Configuration
If the front left/right speakers are set to LARGE, three options are available:
•If no subwoofer is connected to the
AVR 520, press the ‹/› Buttons o 37 on the remote so that NONE appears in the
•If a subwoofer is connected to the AVR 520, you have the option to have the front left/right “main” speakers reproduce bass frequencies at all times, and have the sub- woofer operate only when the AVR 520 is being used with a digital source that con- tains a dedicated Low Frequency Effects, or LFE soundtrack. This allows you to use both your main and subwoofer speakers to take advantage of the special bass created for certain movies. Press ‹/› Buttons
o 37 on the remote so that SUB (LFE) appears in the on-screen menu.
•If a subwoofer is connected and you wish to use it for bass reproduction in conjunction with the main front left/right speakers, regardless of the type of program source or Surround mode you are listening to, press the ‹/› Buttons o 37 on the remote so that SUB LFE+L/R appears in the
When you have completed your selection for the subwoofer, press the ¤ button n on the remote to change the cursor to SUB X- OVER FREQ. The subwoofer crossover set- ting may only be adjusted using the
At this line, you will select the frequency at which bass information is directed to the Subwoofer Output ∞. The choices available will depend on the setting made previously for the front left/right speakers. When making these selections, choose the crossover frequency that is closest to that of your front left/right speakers, or the upper frequency limit of your subwoofer. This figure is normally printed in the owner’s manual or data sheet for the speakers; or consult the speaker’s manufacturer.
•When the front speakers have been set to LARGE, the crossover choices are
40 Hz or 60 Hz to match the typical crossover points of full range speakers. Choose the option that is closest to your speakers’ design.
•When the front speakers have been set to SMALL, the crossover choices are
80 Hz or 100 Hz to match the typical crossover points of the smaller speakers used in satellite speaker systems. Choose the option that is closest to your speakers’ design.
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
If Dolby Digital or Dolby Pro Logic is selected as the surround mode for an input, you may need to adjust the delay time setting. Note that the delay time is not adjustable for any other modes.
Due to the different distances between the listening position for the
The factory setting is appropriate for most rooms, but some installations create an uncom- mon distance between the front and surround speakers that may cause the arrival of front- channel sounds to become disconnected from
To resynchronize the front and surround chan- nels, follow these steps:
1.Measure the distance from the listening position to the front speakers.
2.Measure the distance from the listening position to the surround speakers.
3.Subtract the distance to the surround speak- ers from the distance to the front speakers.
a.When setting the delay time for the Dolby Digital surround modes, the opti- mal delay time is the result of that sub- traction. For example, if the front speak- ers are ten feet away and the surround speakers are five feet away, the optimal
delay time is figured as
b. When setting the delay time for the Pro Logic mode, take the result of the sub- traction and add 15 to obtain the opti- mal delay time. For example, if the front speakers are ten feet away and the sur- round speakers are five feet away, the optimal delay time is figured as
NOTE: The DTS, Logic 7 and DSP modes use a fixed, nonadjustable delay time.
The Dolby Digital mode also includes a separate setting for the Center Channel Delay mode, since the discrete nature of these signals makes the location of the
If the distances are equal, no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker, you may wish to reposition the speakers by moving the front left and front right speakers closer to the listening position or the center speaker further away from the listening position.
If repositioning of the speakers is not possible, adjust the center delay time, adding one milli- second of
To set the delay time for a specific input, the DELAY ADJUST menu (Figure 6) should be visible on your
