Powered Subwoofer Common Features

.  

SVS subwoofer amps use the most durable and accurate designs 
possible.  Get familiar with yours!   

 
Volume/Gain  

Use ―gain‖ (in conjunction with your  Audio Video Re-

ceiver (AVR) subwoofer output level control) to achieve  bass level 
calibration to your liking. Start your setup with the sub’s volume/gain 
no more than  1/4 to 1/3 of the way up (turned clockwise from the 
left). 
  

Crossover Frequency.  

If you use your AVR’s internal crossover to 

manage bass frequencies (highly recommended), the setting of this 
knob on your SVS sub is irrelevant.  (

Note

: Use the sub’s crossover 

―Enable/Disable‖ switch discussed below to take advantage of this 
configuration.)   
 

Phase.  

Think of long bass waves as conflicting or enhancing each 

other, depending on the timing of their arrival at your listening location 
(either together, or not).   Set phase to zero if your AVR offers set-
tings for the distance  from your seat to your subwoofer.  Adjust in 
small steps for smooth sound with music playing if your AVR lacks a 
subwoofer distance setting. 
 

Line In/Out.  

Use either of the sub’s ―Line In‖ jacks (RCA or XLR 

type) to connect the subwoofer to the output jack of your AVR.  Feed-
ing just one input is enough.  If you are using a conventional amp 
and/or a stereo setup you can use the ―Line Out‖ jacks to send sound 
(filtered of deep bass information) back to your system amp, or switch 
off this filter.  A simple RCA signal cable is all you need for either type 
configuration.  See ―Crossover Feature‖ discussion below for more on 
Line Out options. 
 

Auto-On.  

Your Powered Box allows itself to be in an ―Auto-On‖ 

mode… or ―On‖ all the time.  With the former setting (the switch in the 
―Auto‖ position) your subwoofer will ―sense‖ that a DVD or CD etc. 
has begun and switch its audio circuits on immediately (the ―hard‖ 
power switch mentioned below must be set to ―on‖, naturally).  A few 
minutes after a movie, the Auto-On light will turn from Green to Red, 
switching portions of the sub’s power supply back off.
