JVC RX-F31S manual Dual Mono

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:

	Without				With Surround Activated
Dual Mono					Center speaker setting
	Surround
setting				SMALL/LARGE			NO
	L	R	L		C	R	L		R
MAIN	Ch 1	Ch 1			Ch 1		Ch 1		Ch1
SUB	Ch 2	Ch 2			Ch 2		Ch 2		Ch 2
ALL	Ch 1	Ch 2			Ch 1+Ch 2		Ch 1+Ch 2	Ch 1+Ch 2

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.

Setting bass sound

7Setting 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.

7Setting 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.

7Setting 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: –10dBSelect when the bass sound is distorted.

Initial setting: LFE ATT: 0dB
