LARGE
, or
the subwoofer, and bass sounds playing back from those selected as
SMALL
. It also decides where the cutoff
will be for bass sounds in the LFE channel.

With
Full Auto MCACC
setup or
Auto MCACC
setup (
ALL
or

apply and the crossover frequency will be automatically set. Crossover frequency is a frequency aimed at
achieving the optimal sound field taking into account the bass capacity of all connected speakers and human
aural characteristics.

Channel Level
Using the channel level settings, you can adjust the overall balance of your speaker system, an important factor
when setting up a home theater system.
1 Select ‘Channel Level’ from the Manual SP Setup menu.
The test tones will start.
2 Adjust the level of each channel using
k
/
l
.
Use
i
/
j
to switch speakers.
Adjust the level of each speaker as the test tone is emitted.
!
If you are using a Sound Pressure Level (SPL) meter, take the readings from your main listening position and
adjust the level of each speaker to 75 dB SPL (C-weighting/slow reading).
3 When you’re finished, press RETURN.
You will return to the
Manual SP Setup
menu.
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.
1 Select ‘Speaker Distance’ from the Manual SP Setup menu.
2 Adjust the distance of each speaker using
k
/
l
.
You can adjust the distance of each speaker in 0.01 m increments.
3 When you’re finished, press RETURN.
You will return to the
Manual SP Setup
menu.
Note
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 soundtracks.
1 Select ‘X-Curve’ from the Manual SP Setup menu.
2 Choose the X-Curve setting you want.
Use
k
/
l
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:
