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
Use the CURSOR buttons to specify “Subwoofer Peak Limit Lev.” from
the “System Setup Menu” screen.
2
Switch to the Subwoofer Peak Limit Level Setting screen.
ENTER
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).
MASTER VOL.
6
Press the ENTER button at the point where the test noise starts sounding distorted.
The AVR-4800 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.
ENTER
Clear the subwoofer’s peak limit level setting by specifying “Peak Limiter” and “OFF”.
