7Setting the crossover frequency:

When you use a subwoofer, you can select the cutoff frequency for the small speakers used.

Select one of the crossover frequency levels according to the size of the small speaker connected.

80Hz : Select this when the cone speaker unit built in the speaker system is about 12 cm (4 3/4 inches).

100Hz : Select this when the cone speaker unit built in the speaker system is about 10 cm (3 15/16 inches).

120Hz : Select this when the cone speaker unit built in the speaker system is about 8 cm (3 3/16 inches).

Notes:

•Use the above comments as reference when adjusting.

•If you have selected “LARGE” for all activated speakers, this function will be set to “OFF.”

•If “SUBWOOFER” is set to “NO” on the SPEAKER SETTING submenu, this function is not available.

•Crossover frequency is not valid for the DVD MULTI playback mode, ALL CH STEREO mode and 3D HEADPHONE mode.

•If Line Direct is in use, this function does not take effect.

7Setting the low frequency effect attenuator (LFE):

If the bass sound is distorted while playing back software encoded with Dolby Digital or DTS Surround, set the LFE level to eliminate distortion.

Adjust the LFE level within the range of –20 dBto 0 dB. (Normally select “0 dB.”)

•Each time you press #(RIGHT) or @ (LEFT), the LFE level changes by ± 1 dB.

Notes:

•If “SUBWOOFER” is set to “NO” on the SPEAKER SETTING submenu, this function is not available.

•Low frequency effect attenuator is not valid for THX Surround EX and the DVD MULTI playback mode.

7Changing the sound phase:

If the sound output through the subwoofer is not satisfactory, changing the phase will give you a different result.

Select one of the following:

NORMAL	: Normally select this.
REVERSE	: Select this to reverse the phase.

Note:

If “SUBWOOFER” is set to “NO” on the SPEAKER SETTING submenu, this function is not available.

7Using the Bass Peak Limiter:

When this setting is “ON,” Bass Peak Limiter functions so that sounds exceeding the preset peak level (see below) will be cut off.

When this setting is “ON,” you can set the bass peak level using the bass test tone (see below) to eliminate bass sound distortion while playing back software encoded with Dolby Digital or DTS Surround.

Select one of the following:

ON	: Normally select this.
OFF	: Select this when not using the Bass Peak Limiter.

7Outputting the bass test tone:

Only when “BASS PEAK LIMITER” is “ON,” you can output the bass test tone through the subwoofer and/or other speakers (depending on your settings on the SPEAKER SETTING submenu), and adjust the bass peak level (see below).

Select one of the following:

ON	: Select this to output the bass test tone.
OFF	: Select this to stop the bass test tone.

Note:

If “BASS PEAK LIMITER” is set to “OFF,” this function is not

available.

7Setting the bass peak level:

Only when “BASS PEAK LIMITER” is “ON,” you can set the bass peak level so that sounds exceeding the peak level will be cut off to prevent the bass sound distortion.

Adjust the bass peak level within the range of – 12 dBto +18 dB. (Normally select “0 dB.”)

•While listening to the bass test tone, press and hold#(RIGHT) to increase the bass test tone output level, and stop increasing the level just before the test tone is distorted. The level where you stop can be memorized as the bass peak level.

•Each time you press #(RIGHT) or @(LEFT), the bass peak level changes by ± 1 dB.

Note:

When you set “BASS TEST TONE” to “ON,” the bass peak level is

reset to “– – – dB” (no sound).
