JVC RX-DV31 manual Low frequency effect attenuator, Dynamic range compression, Crossover frequency

The distance from your listening point to the speakers is another important element to obtain the best possible surround sound from the Surround modes.

Set the distance from your listening point to the speakers. By referring to the speaker distance setting, this unit automatically sets the delay time of the sound through each speaker so that sounds through all the speakers can reach you at the same time.

•If you have used Quick Setup (see page 23), this setting is not required.

Set the distance from the listening point within the range of 0.3 m to 9.0 m, in 0.3 m intervals.

Notes:

•“3.0m” is the initial setting.

•If you have selected “NO” for the center and surround speakers setting, you cannot set the speaker distance for the center and surround speakers.

Ex.:In this case,	set “FRNT D” to “3.3m,”
	set “CNTR D” to “3.0m” and
	set “SURR D” to “2.7m.”

Select one of the following settings:

80Hz	Select when the cone speaker unit built in the
	speaker is about 12 cm.
100Hz	Select when the cone speaker unit built in the
	speaker is about 10 cm (initial setting).
120Hz	Select when the cone speaker unit built in the
	speaker is about 8 cm.

Note:

•Crossover frequency is not valid for the HEADPHONE mode.

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 LFE signals come in.

Select one of the following settings:

0dB Normally select this (initial setting).

–10dBSelect when the bass sound is distorted.

Small speakers cannot reproduce the bass sounds efficiently. If you use a small speaker in any position, this unit automatically reallocates the bass sound elements assigned to the small speaker to the large speakers.

To use this function properly, set the crossover frequency level according to the size of the small speaker connected.

•If you have selected “LRG (large)” for all speakers, this function will not take effect.

You can compress the dynamic range (difference between maximum sound and minimum sound) of the reproduced sound. This is useful when enjoying surround sound at night.

•This function takes effect only when playing back a source encoded with Dolby Digital.

Select one of the following settings:

MID Select when you want to reduce the dynamic range a little (initial setting).

MAX Select when you want to apply the compression effect fully. (Useful at night.)

OFF Select when you want to enjoy surround with its full dynamic range. (No effect applied.)
