Sony str-dg720 Operating Guide

 

 

You can use the SYSTEM menu to set the size 
and distance of the speakers connected to this 
system.
Select “7-SYSTEM” in the amplifier menus. 
For details on adjusting the parameters, see 
“Navigating through menus” (page 37) and 
“Overview of the menus” (page 38).

x SW SPK (Sub woofer)

• NO

If you have not connected a sub woofer, 
select “NO”. This activates the bass 
redirection circuitry and outputs the LFE 
signals from other speakers.

• YES

If you have connected a sub woofer, select 
“YES”.

In order to take full advantage of the Dolby Digital 
bass redirection circuitry, we recommend setting the 
sub woofer’s cut off frequency as high as possible.

x FRT SPK (Front speakers)

• SMALL

If the sound is distorted, or you feel a lack of 
surround effects when using multi channel 
surround sound, select “SMALL” to activate 
the bass redirection circuitry and output the 
front channel bass frequencies from the sub 
woofer. When the front speakers are set to 
“SMALL”, the center and surround speakers 
are also automatically set to “SMALL” 
(unless previously set to “NO”).

• LARGE

If you connect large speakers that will 
effectively reproduce bass frequencies, 
select “LARGE”. Normally, select 
“LARGE”. When the sub woofer is set to 
“NO”, the front speakers are automatically 
set to “LARGE”.

x CNT SPK (Center speaker)

• NO 

If you have not connected a center speaker, 
select “NO”. The sound of the center 
channel will be output from the front 
speakers.

• SMALL

If the sound is distorted, or you feel a lack of 
surround effects when using multi channel 
surround sound, select “SMALL” to activate 
the bass redirection circuitry and output the 
center channel bass frequencies from the 
front speakers (if set to “LARGE”) or sub 
woofer.

• LARGE

If you connect a large speaker that will 
effectively reproduce bass frequencies, 
select “LARGE”. Normally, select 
“LARGE”. However, if the front speakers 
are set to “SMALL”, you cannot set the 
center speaker to “LARGE”.

x SUR SPK (Surround speakers)

The surround back speakers will be set to the 
same setting.
• NO

If you have not connected surround 
speakers, select “NO”.

• SMALL

If the sound is distorted, or you feel a lack of 
surround effects when using multi channel 
surround sound, select “SMALL” to activate 
the bass redirection circuitry and output the 
surround channel bass frequencies from the 
sub woofer or other “LARGE” speakers.

• LARGE

If you connect large speakers that will 
effectively reproduce bass frequencies, 
select “LARGE”. Normally, select 
“LARGE”. However, if the front speakers 
are set to “SMALL”, you cannot set the 
surround speakers to “LARGE”.
