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

Selecting the main or sub channel
—DUAL MONO

You can select the playback sound (channel) you want while
playing digital software recorded (or broadcasted) in Dual Mono
mode (see page 36), which includes two monaural channels
separately.

DUAL MONO: MAIN

Select to play back the main channel (Ch 1).*
Signal indicator “L” lights up while playing back this channel.

DUAL MONO: SUB

Select to play back the sub-channel (Ch 2).*
Signal indicator “R” lights up while playing back this channel.

DUAL MONO: ALL

Select to play back both the main and sub-channels (Ch 1/Ch 2).*
Signal indicators “L” and “R” light up while playing back these
channels.

Initial setting: DUAL MONO: MAIN

* Dual Mono signals can be heard from the following speakers—L

(left front speaker), R (right front speaker), and C (center
speaker), with respect to the current Surround setting:

NOTE

The Dual Mono format is not identical with bilingual broadcasting
for TV programs. So this setting does not take effect while
watching such bilingual programs.
