SV Sound
Chapter 5-1
Powered Box/Cylinder Common Fea-
tures: 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 type) to
connect the subwoofer to the output jack of your AVR. Feeding 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 con-
figuration. 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.
