If you are running a pair of SV Subwoofers (Fig. 2),  you will need to use 
a standard “Y” cable adapter (d.)  The best adaptor to use for this task has 
one male RCA connection and two female RCA outputs.  (Radio Shack ® 
stocks them.)  From the “Y” cable you can run a standard 75 Ohm RCA 
to RCA signal cable (e.) to each sub, thus “splitting” the Low Frequency 
Effects (LFE) and other bass signals from your receiver and effectively 
feeding both subwoofers with the same signal.

This isn’t only for tech minded folks, it’s 

critical 

to a 

proper configuration of your home theater sound system. Fortunately, 
adjusting channel balance (or, calibration) is as easy to do as it is impor-
tant.  The first order of business is making sure your DD/DTS surround- 
sound system is set up properly.  We recommend you consult your audio/
video receiver (or processor) manual to refresh on the procedures to do 
this.  Generally, this requires ensuring the receiver’s test tones, or a spe-
cial test disk (like 

Avia

) play back at the same volume from each of your 

system’s full range speakers.  That’s left, center, right, left surround and 
right surround (and if equipped, center rear) speakers, plus the sub-
woofer . (More on sub level in a second).  Skip to Page 7 (“

calibration. 

 

S

ome things to check as you get ready to calibrate:

 

• 

A

re your speakers set to the correct “size”?  

Your receiver/

processor should allow you to indicate if your speakers are  “Small” or 
“Large”.  Selecting the size accordingly will ensure bass goes to most appro-
priate speakers, and use the subwoofer correctly too. In most instances set-

NOTE:  

Now is a good time to select if 

you want “ON” (always on) or “AUTO 

ON” which turns your sub on only when a bass 
signal is present.
