Setting bass sound

7 Setting subwoofer output—SUBWOOFER OUT
You can select the type of the signal which can be transmitted
through the subwoofer. In other words, you can determine
whether or not the bass elements of the front speaker channels
are transmitted through the subwoofer regardless of the front
speaker size setting (either "SMALL" or "LARGE").
SUBWFR OUT: LFE
Select to emit only the LFE signals (while playing Dolby
Digital and DTS software) or the bass elements of the
"SMALL" front speakers (while playing any source other than
above).
SUBWFR OUT: LFE+MAIN
Select to always emit the bass elements of the front speaker
channels (MAIN). While playing Dolby Digital and DTS
software, the bass elements and the LFE signals are both
emitted.
Initial setting: SUBWFR OUT: LFE
NOTE
When "SUBWOOFER" is set to "SUBWOOFER: NO" (see page
21), this function is not available.
7 Setting the crossover frequency—CROSSOVER
Small speakers cannot reproduce the bass sounds efficiently. If
you use a small speaker in any position, this receiver
automatically reallocates the bass sound elements assigned to
the small speaker to the large speakers.
To use this function properly, set this crossover frequency level
according to the size of the small speaker connected.
• If you have selected "LARGE" for all speakers (see page 21),
this function will not take effect ("CROSSOVER: OFF" appears).
CROSSOVER: 80Hz Select when the cone speaker unit built in
the speaker is about 12 cm.
CROSSOVER: 100Hz Select when the cone speaker unit built in
the speaker is about 10 cm.
CROSSOVER: 120Hz Select when the cone speaker unit built in
the speaker is about 8 cm.
CROSSOVER: 150Hz Select when the cone speaker unit built in
the speaker is about 6 cm.
CROSSOVER: 200Hz Select when the cone speaker unit built in
the speaker is less than 5 cm.
Initial setting: CROSSOVER: 150Hz
NOTE
Crossover frequency is not valid for the HEADPHONE and 3D
HEADPHONE modes.
7 Setting the low frequency effect attenuator
—LFE ATT
If the bass sound is distorted while playing back software
encoded with Dolby Digital or DTS, set the LFE level to eliminate
distortion.
• This function takes effect only when the LFE signals come in.
LFE ATT: 0dB Normally select this.
LFE ATT: –10dB Select when the bass sound is distorted.
Initial setting: LFE ATT: 0dB
