Speaker/Output Setup—Continued

Speaker Crossover Sub-menu

The settings in the Speaker Crossover sub-menu can be configured for both “Main A” and “Main B.”

Front L/R, Center, Surr L/R, Surr Back

Specify a threshold frequency in Hz for bass sounds from each speaker to be output from the subwoofer. When no subwoofer is used, (Speaker A) Front L/R is automatically set to “Full Band,” and bass sounds from each speaker are output from the front speakers. You can also set other speakers to “Full Band.”

You can specify the frequency at 10 Hz increments between 40-150 Hz. When using a THX-Select-certified speaker system, specify the setting of 80 Hz (THX) (default).

•If you specify the frequency of the front speakers between 40-150 Hz, you cannot select “Full Band” for the other speakers.

•For any speaker that is not available or set to “Not Used” in the Speaker Configuration sub-menu, no associated setting item is displayed.

•If “Surr Back” is set to “Bi-Amp for Front” on the Speaker Configuration sub-menu, no item for surround back speakers is displayed.

LPF of LFE (setting of the low-pass filter for LFE)

Specify the low-pass filter for LFE (Low Frequency Effect).

The low-pass filter passes through only the signal components below the specified frequency, eliminating the unwanted noise.

You can specify the frequency at 10 Hz increments between 40-150 Hz.

SW Mode (Subwoofer Mode)

This item is displayed when a subwoofer is used (any item other than “Not Used” is selected for Subwoofer on the Speaker Configuration sub-menu), and Front L/R is set to “Full Band” on the Speaker Crossover sub- menu. Set the sound from the subwoofer to any of the following:

LFE only: The subwoofer outputs only LFE (Low Frequency Effect) information.

D. Bass: The subwoofer outputs not only LFE (Low Frequency Effect) factors but also bass sounds from the front speakers.

Speaker Distance Sub-menu

Measure the distance between the listening position and each speaker. Specifying the distance will synchronize the speakers in terms of the time that sounds from each speaker reach the listening position. This is an important specification for you to enjoy realistic home theater. The settings in the Speaker Distance sub-menu can be configured for both “Main A” and “Main B.” Perform the setup procedure below following the operating instructions described on page 90.

1.Select the unit of distance from “Unit.”

You can select either “feet” or “meters.” The default varies depending on the region.

2.Set the distance you measured. Enter all the values for every speaker you connected.

•For any speaker that is not available or set to “Not Used” in the Speaker Configuration sub-menu, no associated setting item is displayed.

•If “Surr Back” is set to “Bi-Amp for Front” on the Speaker Configuration sub-menu, no item for

surround back speakers is displayed.
When “feet” is selected:
Front L, Center, Front R, and Subwoofer can be set at
0.1 foot intervals in a range from 1.0 foot to 30.0 feet.
The default is 12.0 feet.
Surr R, Surr Back (or Surr Bk R and Surr Bk L), and
Surr L can be set at 0.1 foot intervals in a range from 1.0
foot to 30.0 feet. The default is 7.0 feet.
When “meters” is selected:
Front L, Center, Front R, and Subwoofer can be set at
0.03 meter intervals in a range from 0.30 meters to 9.00	Menu
meters. The default is 3.60 meters.
Surr R, Surr Back (or Surr Bk R and Surr Bk L), and
Surr L can be set at 0.03 meter intervals in a range from	Setup
0.30 meters to 9.00 meters. The default is 2.10 meters.

Notch Filter Sub-menu

To configure the settings under the Notch Filter sub- menu, a special measuring device is required. Usually, leave these settings to their defaults, “Off.”

A notch filter cuts the signal of certain frequency ranges and passes the rest of the signal through. Some characteristics due to a room’s environmental elements, including walls and smallness of the room, cause a signal peak in certain low frequencies to occur

at the resonance frequency, resulting in a boomy sound. The filter reduces the signal at these frequencies causing the boomy sound.

To know which frequency the peak occurs at, use a low frequency sine wave generator and SPL (Sound Pressure Level) meter to check the frequency and the notch value.

Notch Filter

Off (Default): Select this setting when not applying the notch filter.

On: Select this setting when applying the notch filter.

Frequency

When setting “Notch Filter” above to “On,” the notch filter becomes effective at the frequency you specify here. With your measuring device, the frequency value can be set at 1 Hz intervals in a range from 20 Hz to 300 Hz. The default is 100 Hz.
