Subwoofer Operation - Panasonic SC-ELS10 Operating Instructions Manual

Subwoofer operation

The active subwoofer reproduces very low frequency sound monaurally, making use of the fact that the human ear does not sense
direction in the low frequency region.
You can emphasize low frequencies by combining the active subwoofer with the speaker system.
1
Set [POWER] to " k ON".
The power indicator turns green.
Output sound from the receiver  and
2
adjust the volume to a suitable level.
• Do not adjust the bass as this can cause distortion.
• If the volume control on the receiver is left in the minimum position or there is no signal from the receiver for more than
8 minutes, the active subwoofer will automatically switch to standby and the power indicator will turn red. If you turn up
the volume control on the receiver or if a signal enters the subwoofer from the receiver, the subwoofer will automatically
switch to the operation mode and the power indicator will turn green.
Note, however, that the subwoofer may sometimes fail to switch to standby due to noise emitted by the receiver to which
it is connected.
Set [LOW PASS FILTER].
3
• Refer to "Frequency response by LOW PASS FILTER setting"  .
• Set [LOW PASS FILTER] to 200 Hz.
Adjust [VOLUME] to a suitable level.
4
• Gradually turn up the volume control from the minimum position and set it in a position where the output from the
subwoofer is balanced with the front speakers and also there is no distortion in the low frequency region.
Set the volume to near center.
•
• Refer to "Level change according to volume control setting"  .
Play something, then set [PHASE] to "l NORMAL" or "k REVERSE" so
5
the sound is normal.
The subwoofer and speakers cancel each other output (causing unusual, muffled sound) if the phase setting is incorrect.
n Set [POWER] to "l OFF".
The power indicator turns off.
When you wish to reproduce 2-channel stereo music
The output in the low range sometimes may be excessively high depending on the setting of the receiver and the active subwoofer
when you are reproducing a multi-channel movie source.
Reduce the subwoofer level at the receiver side.
Also, note that you may be able to obtain more natural sound quality by reducing the frequency of the "low-pass filter" on the active
subwoofer.
Note
If the volume output is too loud, the active subwoofer's amplifier can be clipped, causing output to sound unusual. Reduce the volume
of the receiver or the volume of the active subwoofer if this occurs.
When settings are complete
The only operation you should have to perform daily is press [POWER] to turn the subwoofer ON/OFF.
14
If you reposition the system and the acoustics change, reset the subwoofer as necessary.
