Channel Level - Pioneer sc-9540 Operating Instructions Manual

12 The system and the other setup
• SB – Select the number of surround back speakers
you have (one, two or none).
LARGEx1 if your surround back speakers reproduce
bass frequencies effectively. Select SMALLx2 or
SMALLx1 to send bass frequencies to the other
speakers or subwoofer. If you didn't connect
surround back speakers choose NO.
• SW – 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).
not connect a subwoofer choose NO (the bass
frequencies are output from other speakers).
3 Select 'X.OVER' and set the crossover frequency.
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.

2 Select a setup option.
• MANUAL – Move the test tone manually from
speaker to speaker and adjust individual channel
levels.
Note
1 • If you selected Speaker B, ZONE 2 or Front Bi-Amp (in Surround back speaker setting on page 109) 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.
2 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.
3 • 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.
4 • 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.
5 The channel level cannot be adjusted using this procedure while making settings on HOME MENU.
