Speaker Distance

For good sound depth and separation from your system, you need to specify the distance of your speakers from the listening position. The receiver can then add the proper delay needed for effective surround sound.

1Select ‘Speaker Distance’ from the Manual SP Setup menu.

5.Manual SP		Setup	5c.Speaker		Distance
	a.Speaker	Setting	L
					3.0 m
	b.Channel	Level	C	[	3.0 m	]

2Adjust the distance of each speaker using the / buttons.

You can adjust the distance of each speaker in 0.1 meter increments.

2 Choose the X-Curve setting you want.

Use / to adjust the setting. The X-Curve is expressed as a downwards slope in decibels per octave, starting at 2 kHz. The sound becomes less bright as the slope increases (to a maximum of -3.0dB/oct). Use the following guidelines to set the X-Curve according to your room size:

Room size (m2)	≤36	≤48	≤60	≤72	≤300	≤1000
X-Curve (dB/oct)	–0.5	–1	–1.5	–2	–2.5	–3

•If you select OFF, the frequency curve will be flat and the X-Curve has no effect.

3 Select ‘Return’ then press ENTER to finish.

THX Audio Setting

For the most effective results when using the THX Select2 Cinema and THX MusicMode listening modes (see Using the Home THX modes on page 27) with the Advanced Speaker Array (ASA) system (see About THX on page 75), it is required that you make the setting. See THX speaker system setup on page 19 for more on THX speaker

Tip

•For best surround sound, make sure the surround back speakers are the same distance from the listening position.

X-Curve

Most soundtracks mixed for cinema sound too bright when played back in large rooms. The X-Curve setting acts as a kind of re-equalization for home theater listening, and restores proper tonal balance of movie
