With this setting, you can specify the cutoff frequency of 
the LFE channel’s low-pass filter (LPF), which can be 
used to filter out unwanted hum. The LPF only applies to 
sources that use the LFE channel.

With the Double Bass function, you can boost bass out-
put by feeding bass sounds from the front left and right 
channels to the subwoofer. This function can be set only 
if the Subwoofer setting in step 3 is set to Yes, and the 
Front setting in step 4 is set to Full Band.
In the speaker setup screen, you can choose how bass 
information is distributed to your speakers only if you 
have large front left and right speakers AND a subwoofer.

Note:
This procedure can also be performed on the AV receiver 
by using its [SETUP] button, arrow buttons, and 
[ENTER] button.

If no surround left and right speakers 
are connected, select None.

Note:
If the Front setting in step 4 is set to 
anything other than Full Band, Full 
Band cannot be selected here.

Continue with step 7 in the right col-
umn.

The following low-pass filter frequen-
cies can be selected: 80 Hz, 100 Hz, 
120 Hz (default), 150 Hz, or 200 Hz.
Continue with step 10 below.

On:  Double Bass function on 

(default). Front left and right 
bass also goes to the sub-
woofer simultaneously.

Off:  Double Bass function off. 

The setup menu closes.

To test that all of the speakers are working properly, 
press the remote controller’s [TEST TONE] but-
ton. 

The test tone will be output by each speaker in turn 
and the name of each speaker will appear on the dis-
play. To turn off the test tone, press the [TEST 
TONE] button again.
• If the test tone is not produced by a speaker, or it’s 

produced by a speaker other than that shown on 
the display, you may have wired the speakers 
incorrectly and you should check your connec-
tions (see page 20).

• If the test tone is not produced by a speaker and its 

name does not appear on the display, you may 
have set the speaker configuration incorrectly (see 
page 42).
