“EXPERT” adjustment procedure

7Adjusting the delay time for the center and rear

speakers

You can adjust the delay time of the sounds from the center speaker and from the rear speakers, comparing to that of the sound from the front speakers.

If the distance to the center speaker and/or rear speakers from your listening position is almost the same as that to the front speakers, select “0 ms” (the default setting for “5.1CHANNEL” settings).

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

Ex.: In this case, set “C.SPK–DELAY” to “–1 ms” and “R.SPK–DELAY” to “–5 ms.”

If you can locate the speakers as the above example, you can select “5.1CHANNEL” for your speaker setting.

If you can NOT do as above, select “EXPERT,” then press ENTER. EXPERT SPEAKER SETTING menu appears and you can adjust the output level and delay time for the center and rear speakers.
