Setting the speaker delay time

—CNTR DL (center speaker delay), SURR DL (surround speakers delay)

You can set the speaker delay time easily by using Smart Surround Setup (see page 15) or Quick Setup (see page 16).

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

You need to set the delay time of the center and surround speakers relative to the front speakers so that sounds through all the speakers can reach you at the same time.

•1 msec increase (or decrease) in delay time corresponds to 30 cm increase (or decrease) in distance.

CNTR DL*: Set the delay time for the center speaker within a range of 0 msec to 5 msec (in 1 msec intervals).

SURR DL*: Set the delay time for the surround speakers within a range of 0 msec to 15 msec (in 1 msec intervals).

*“0ms” is the initial setting.

Setting the crossover frequency—CROSS

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 17), this function will not take effect.

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.

120HZ: Select when the cone speaker unit built in the speaker is about 8 cm.

150HZ*: Select when the cone speaker unit built in the speaker is about 6 cm.

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 mode.

Setting the low frequency effect attenuator —LFE

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.

0dB*: Normally select this.

–10dB:Select when the bass sound is distorted.

*Initial setting

Setting the dynamic range compression —D.COMP

Example: In this case,

set “CNTR DL” to “1ms” and set “SURR DL” to “2ms.”

NOTE

If you have selected “NO” for the center and surround speakers setting (see page 17), you cannot set the speaker delay time for the center and surround speakers.

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

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

OFF: Select when you want to enjoy surround with its full

dynamic range. (No effect applied.)

MID*: Select when you want to reduce the dynamic range a little.

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