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 41), which includes two monaural channels separately. When the receiver detects Dual Mono signals, the DUAL MONO indicator lights up on the display.

• You cannot adjust directly from the remote control.

D MONO MAIN Select to play back the main channel (Ch 1).*

Signal indicator “L” lights up while playing back this channel.

D MONO SUB Select to play back the sub-channel (Ch 2).*

Signal indicator “R” lights up while playing back this channel.

D 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: 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:

Dual	Without			With Surround Activated
				Center speaker setting

				SML/LRG			NO
setting
	L	R	L	C	R	L		R
MAIN	Ch 1	Ch 1	—	Ch 1	—	Ch 1		Ch 1

ALL	Ch 1	Ch 2	—	Ch 1+Ch 2	—	Ch 1+Ch 2		Ch 1+Ch 2

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.

Setting bass sound

•You cannot adjust these items directly from the remote control.

7 Setting subwoofer output—SUBWOOFER OUT

The subwoofer emits the LFE signals* and the bass elements of each speaker set “SML (small).”

You can also make the bass elements of the front speakers (MAIN) emitted through the subwoofer.

SW LFE	The subwoofer emits the LFE signals and
	the bass elements of the speakers set to
	“SML (small).”
SW LFE+MAIN	The subwoofer emits the LFE signals and
	the bass elements of the speakers set to
	“SML (small).” The subwoofer also emits
	the bass elements of front speakers (MAIN)
	when no LFE signal nor the bass elements
	of “SML (small)” speakers exist.
Initial setting:	LFE

*The LFE signals are emitted only when playing the following software with the LFE signals:

–Dolby Digital multi-channel software

–DTS multi-channel software

When playing analog source or linear PCM software, no LFE signal is emitted.

NOTE

When “SUBWOOFER” is set to “NO” (see page 30), you cannot select “SUBWOOFER OUT.”

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 “LRG (large)” for all speakers (see page 30), this function will not take effect (“CROSS OFF” appears).

•If you have performed Precise Surround Setup on pages 16 to 18, this setting is not required.

Adjustable range: 80 Hz to 200 Hz (in 10 Hz intervals)

Initial setting: 100 Hz

The following are examples of the setting:

CROSS 80Hz Select when the cone speaker unit built in the speaker is about 12 cm.

CROSS 100Hz Select when the cone speaker unit built in the speaker is about 10 cm.

CROSS 120Hz Select when the cone speaker unit built in the speaker is about 8 cm.

CROSS 150Hz Select when the cone speaker unit built in the speaker is about 6 cm.

CROSS 200Hz Select when the cone speaker unit built in the speaker is less than 5 cm.

NOTE

Crossover frequency is not valid for the HEADPHONE and 3D HEADPHONE modes.
