2 Choose the set of speakers that you want to set
then select a speaker size.
Use / to select the size (and number) of each of the
following speakers:
1
• Front – Select LARGE if your front speakers
reproduce bass frequencies effectively, or if you
didn’t connect a subwoofer. Select SMALL to send
the bass frequencies to the subwoofer.
• Center – Select LARGE if your center speaker
reproduces bass frequencies effectively, or select
SMALL to send bass frequencies to the other
speakers or subwoofer. If you didn’t connect a center
speaker, choose NO (the center channel is sent to
the other speakers).
• Surround – Select LARGE if your surround speakers
reproduce bass frequencies effectively. Select
SMALL to send bass frequencies to the other
speakers or subwoofer. If you didn’t connect
surround speakers choose NO (the sound of the
surround channels is sent to the other speakers).
• Surr Back – Select the number of surround back
speakers you have (one, two or none).
2
Select LARGE
if your surround back speakers reproduce bass
frequencies effectively. Select SMALL to send bass
frequencies to the other speakers or subwoofer. If you
didn’t connect surround back speakers choose NO.
• Subwoofer – LFE signals and bass frequencies of
channels set to SMALL are output from the
subwoofer when YES is selected. Choose the PLUS
setting if you want the subwoofer to output bass
sound continuously or you want deeper bass (the
bass frequencies that would normally come out the
front and center speakers are also routed to the
subwoofer).
3
If you did not connect a subwoofer
choose NO (the bass frequencies are output from
other speakers).
3 Select ‘X. OVER’ and set the crossover frequency.
4
Frequencies below this point will be sent to the
subwoofer (or LARGE speakers).
4 When you’re finished, press RETURN.
You will return to the Manual SP Setup menu.
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.
2 Select a setup option.
• Manual – Move the test tone manually from speaker
to speaker and adjust individual channel levels.
• Auto – Adjust channel levels as the test tone moves
from speaker to speaker automatically.
3 Confirm your selected setup option.
The test tones will start after you press ENTER.
4 Adjust the level of each channel using the
/
buttons.
If you selected Manual, use / to switch speakers. The
Auto setup will output test tones in the order shown on-
screen:
Adjust the level of each speaker as the test tone is
emitted.

Note
1 If you select SMALL for the front speakers the subwoofer will automatically be fixed to YES. Also, the center and surround speakers can’t be set to LARGE
if the front speakers are set to SMALL. In this case, all bass frequencies are sent to the subwoofer.
2 • If you selected Speaker B or Front Bi-Amp (in Surround back speaker setting on page 39) you can’t adjust the surround back settings.
• If the surround speakers are set to NO, the surround back speakers will automatically be set to NO.
• If you select one surround back speaker only, make sure that speaker is hooked up to the left surround back terminal.
3 If you have a subwoofer and like lots of bass, it may seem logical to select LARGE for your front speakers and PLUS for the subwoofer. This may not,
however, yield the best bass results. Depending on the speaker placement of your room you may actually experience a decrease in the amount of bass due
low frequency cancellations. In this case, try changing the position or direction of speakers. If you can’t get good results, listen to the bass response with
it set to PLUS and YES or the front speakers set to LARGE and SMALL alternatively and let your ears judge which sounds best. If you’re having problems,
the easiest option is to route all the bass sounds to the subwoofer by selecting SMALL for the front speakers.
4 • This setting decides the cutoff between bass sounds playing back from the speakers selected as 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.
• If you’re using a THX speaker setup, confirm that the crossover frequency is set to 80Hz.
5 • 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).
• The subwoofer test tone is output at low volumes. You may need to adjust the level after testing with an actual soundtrack.
