Subwoofer peak limit level setting
• This unit features a subwoofer peak limit control which prevents distortion and damage in the loudspeaker
system by controlling the maximum bass volume level. With this feature you may set the maximum bass level
for the system.
• This feature operates with or without a subwoofer in the system.
1
At the System Setup Menu select "Subwoofer Peak Limit
Lev.".
2
Switch to the Subwoofer Peak Limit Level Setting screen.
3
Select "ON" for Peak Limiter.
4
The screen switches. Select "Setting
Start", then select "Yes".
The screen switches and a test noise is
produced from the speaker system.
5
Increase the master volume level until the test noise is
distorted.
The test noise (bass sound) is distorted when it sounds as if
the input is excessively high (when the sound crackles).
6
Press the ENTER button at the point where the test noise starts sounding distorted.
The AVC-A1SR automatically sets the subwoofer peak limit level.
This prevents future inadvertent subwoofer overload due to excessively strong bass
content when the master volume control is at a high level.
Clear the subwoofer's peak limit level setting by specifying "Peak Limiter" and "OFF".
CAUTION!
• The master volume is set to "–30 dB" when test tones are output.
• The test tones are for confirming the low frequency playback limits and are played at an extremely high
level. When using a low output subwoofer, be very careful about irregular operations exceeding clipping by
for example turning down the subwoofer's attenuator before starting then slowly turning the attenuator up
to the listening level.
• Also, when the subwoofer is set to "NO" in the speaker configuration, the test tones are output from the
front speakers. When using front speakers with low input resistance, check that the sound is not clipped
at sections where the signal is strong on the CD music source before starting the peak limit setting. The
peak limit setting should not be performed if the music source cannot be played with the master volume
set at "–15". Set the front speakers to "small" and the subwoofer to "YES" in the speaker configuration.
When this is done, the low frequencies are cut, so the effect is insufficient. We strongly recommend adding
a subwoofer.
• If the test tone is clipped when it is set to "–18 dB", set the peak limit to "–18 dB". In this case, the input
resistance of the subwoofer or front speakers is insufficient so clipping may occur when playing music. We
recommend switching to a subwoofer with a higher input resistance.
Setting the Digital In Assignment
• This setting assigns the digital input jacks of the AVC-A1SR for the different input sources.
1
At the System Setup Menu select "Digital In Assignment".
2
Switch to the Digital In Assignment screen.
3
Select the digital input jack to be assigned to the input source.
• To select the input source
• To select the digital input jack
Select "OFF" for input sources for which no digital input jacks are used.
If "Yes" is selected for "Default", the settings are automatically reset to
the default values.
4
Enter the setting.
The System Setup Menu reappears.
