If the front left/right speakers are set to SMALL, the subwoofer will automatically be set to SUB, which is the “on” position.
If the front left/right speakers are set to LARGE, three options are available:
•If no subwoofer is connected to the AVR 230, press the ‹/› Buttons o on the remote so that NONE appears in the on-screen menu.
When this option is selected, all bass information will be routed to the front left/right “main” speakers.
•If a subwoofer is connected and you wish to have the front left/right “main” speakers reproduce bass frequencies at all times, and have the subwoofer operate only when the AVR 230 is being used with a digital source that contains a dedicated Low-Frequency Effects, or LFE, soundtrack. Press the ‹/› Buttons o on the remote so that 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, press the ‹/› Buttons o on the remote so that SUB LFE+L/R appears in the on-screen menu. When this option is selected, a full-range signal will be sent to the front left/right “main” speakers, and the subwoofer will receive the bass frequen- cies under frequency selected, as described below, as well as the LFE information.
When all initial speaker “size” settings have been made, you now have the option to take advantage of the AVR 230’s Triple Crossover system, which allows individual crossover settings to be made for each speaker grouping. The low-frequency crossover point is set by the design of your speakers. Depending on the design and driver complement of your speakers, it is defined as the frequency which is either the lowest possible frequency the speaker is capable of repro- ducing, or the frequency at which sound is sent to the speaker’s internal low-frequency driver, as opposed to the mid-range driver. Before making any changes to the settings for the crossover point, we suggest that you find the crossover point for the speakers in each of the three groupings, front left/right, center and sur- rounds, by looking at the specifications page of each speakers’ owner’s manual, or by contacting your dealer or the manufacturer’s customer service department or Web site. You will need this figure to accurately configure the next group of settings.
The factory default setting for all speaker positions is 100Hz. If that setting is acceptable for all channels, then no adjustments are needed and you may skip this section. However, should you wish to change one
of the settings, please proceed by pressing the ⁄ Button n so that the cursor moves back up to the top of the list of setting options. Press the ⁄/¤ Buttons n so that X-OVERis highlighted and the menu data will change to the screen shown in Figure 6.

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 until the desired setting appears. The available choices at which point low-frequency 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 possible, 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 system 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 subwoofer. Note, also, that when the LARGE- LFE+L/R setting has been selected, the crossover point is set by making adjustments at the SUBWOOFER line, but the setting for the front left/right speakers will automatically change in tandem so that the same setting appears for both speaker positions. This ensures that there is no “hole” in the sound field due to different crossover points at the front and subwoofer speakers.
When all crossover settings have been made, or in those cases where none are needed, 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 con- figuration, crossover settings and output levels for all inputs, or to 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 individualized settings. However, some listeners,
particularly those with full-range front speakers that are used for both movies and music, may prefer that dif- ferent crossover points be used 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 speaker settings and out- put levels for each input, make certain that the cursor is on the BASS MGR line and press the ‹/› Buttons o so that INDEPENDENT appears. When this setting is entered by exiting the menu, you may need to go back to the INPUT menu to select another input, and then return to this menu page again to change the settings for that input. Repeat the procedure for any input where you wish to have a different set of speaker configuration and crossover settings.
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 channel speakers and the sur- round speakers, the amount of time it takes for sound to reach your ears from the front versus surround speakers differs. You may compensate for this differ- ence through the use of the delay settings to adjust the timing for the speaker placement and acoustic conditions in your listening room or home theater.
The AVR 230’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 distance 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 measurement 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 recommend that delay times be adjusted using the Dolby Digital mode. If a different mode is selected at a later time, the AVR 230 will automatically restrict the delay settings to those required by the surround mode in use.
