Fine Channel Delay

For proper sound depth and separation with your system, it is necessary to add a slight bit of delay to some speakers so that all sounds will arrive at the listening position at the same time. The following setting can help you make detailed adjustments that you may not achieve using the Normal surround setting on page 55.

1Select ‘Fine Channel Delay’ from the Expert setup menu.

2Adjust the distance of the left channel from the listening position.

Left [ 2 . 0 m ]

3Select each channel in turn and adjust the distance as necessary.

Use (cursor up/down) to adjust the delay of the speaker you selected to match the front left (reference) speaker. The delay is measured in terms of speaker distance from 0.1 to 9.0 meters.

Center		[ 2 . 0	m ]

	R
SurrBack	L	[ 2 . 0 m ]
SurrBack	R	[ 2 . 0 m ]
Subwoofer		[ 2 . 0	m ]
[ Exit ]

Listen to the reference speaker and use it to measure the target channel. Face the two speakers with your arms outstretched pointing at each speaker. Try to make the two tones sound as if they are arriving simultaneously at a position slightly in front of you and between your arm span.

When it sounds like the delay settings are matched up, press ENTER to confirm and continue to the next channel.

• If you want to go back and adjust a channel, simply

use (cursor up/down) to select it.

4When you're finished, select ‘Exit’. You will return to the Expert setup menu.

Acoustic Calibration EQ

Acoustic Calibration Equalization is a kind of room equalizer for your speakers (excluding the subwoofer). It works by measuring the acoustic characteristics of your room and neutralizing the ambient characteristics that can color the original source material. You can also make these settings manually to get a frequency balance that suits your tastes. A more advanced setup is also available, where you can make detailed settings according to your room’s reverb characteristics (see Professional Acoustic Calibration on page 91). You should have the mic connected when using any of the setup options.

Setting the Acoustic Calibration EQ automatically

If you have already completed Automatically setting up for surround sound on page 12, ALL CH ADJUST and FRONT ALIGN (below) should already be set. Therefore, if you want to adjust your settings manually, you can skip to Setting the Acoustic Calibration EQ manually below.

1Select ‘Acoustic Cal EQ’ from the Expert setup menu.

As the receiver outputs test tones, the frequency balance is adjusted automatically for the following settings:

• ALL CH ADJUST – All the speakers are set individually so no special weighting is given to any one channel.

• FRONT ALIGN – All speakers are set in accordance with the front speaker settings.
