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 AVR-4802R 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.
To cancel the setting, use the cursor buttons on the Subwoofer Peak Limit Level Setting screen after step 2 to select OFF for Peak
Limiter.
3
Select ON for Peak Limiter.
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 subwoofers 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.
