Sony STR-K990 매뉴얼

This receiver allows you to use a 5.1 channel 
system (5 speakers and one sub woofer).
To fully enjoy theater-like multi channel 
surround sound requires five speakers (two 
front speakers, a center speaker, and two 
surround speakers) and a sub woofer (5.1 
channel).

FSub woofer

Since the sub woofer does not emit highly 
directional signals, you can place it wherever you 
want.

Before you install the speakers and sub 
woofer, be sure to attach the supplied foot pads 
to prevent vibration or movement as shown in 
the illustration below. 

For greater flexibility in positioning the 
speakers, use the optional WS-FV11 or

 

WS-FV10D speaker stand (available only in 
certain countries). Be sure to detach the screw 
from the speaker and use it when you install 
the speaker to the speaker stand. For details, 
refer to the operating instructions supplied 
with the speaker stand.
