Thank you for upgrading to the Sledge STA-1200D. Your new amplifier delivers greater performance
along with advanced control and calibration features only available via the SVS Subwoofer Control
mobile app. Please follow all instructions carefully to ensure proper installation of your new amplifier.
Parts and Tools needed: • One #2 square drive bit (included).
• Male spade output adapter for Sledge STA-1200D amplifier (included).
• (10) replacement amplifier screws (included).
• A hand-held or power bit driver.
• A drive bit extender (optional for PC13-Ultra).
Turn off the main power switch. Disconnect the power cord and the input cable. Wait 30
minutes before continuing to the next step. This will ensure that all residual power has
drained from the amplifier.
Remove the ten (10) #2 square drive outer
perimeter wood screws from the amplifier
plate with the provided bit. For the PC13-Ultra,
a drive bit extender may be helpful to reach
the top/bottom middle screws on the plate, as
these are the most recessed relative to the
curvature of the cylinder tubing.
Partially remove the amplifier from the
enclosure, taking care not to disconnect
any wiring connections. If the amplifier
seems stuck in the enclosure, please
contact our SVS Sound Experts for advice
on how to remove it.

The Sledge STA-1200D replacement amp for the 13-Ultra subwoofers can only be controlled
with the SVS Subwoofer Control mobile app. This app is available for free via the Apple®
App® Store, Google Play™ Store and Amazon Appstore.
11.
Place the Sledge STA-12000D replacement amplifier fully into the cabinet. Press down gently
and evenly around the perimeter of the amplifier to ensure it is fully seated into the cabinet
opening.
7.
Carefully insert and tighten the ten (10) included
#2 square drive wood screws. Hand-snug the
screws in a cross-torque pattern (i.e., top-to-bot-
tom, side-to-side, and opposite diagonal corners)
to ensure uniform seating of the plate.
Do not over-tighten screws – a firm hand-snug is
sufficient. If you are using a power bit driver with
a slip clutch, use the #4 clutch setting.
8.
Carefully reposition the subwoofer back to its original location, and reconnect the power
cord and input cable.
Turn on the main power switch.

10.
Disconnect the two female spade woofer connection wires from the Sledge STA-1000D
amplifier plate. Then remove the Sledge STA-1000D amplifier completely and set aside.
4.
Connect the female spades of the woofer wires to the male spades of the Sledge STA-1200D
output adapter. Observe proper polarity (red positive, black negative). Make sure the female
spade connections are tight and carefully crimp them as needed for a tight fit.
5.
While supporting the Sledge STA-1200D replacement amplifier partially in the subwoofer
cabinet, connect the white plastic section of the included output adapter to the Sledge
STA-1200D output board. Note, this is a one-way connection with a locking tab.

If you’re using an AV processor with auto-setup, re-run that process. You may need a slightly
different volume setting on the Sledge STA-1200D to achieve the same overall calibration
level as you had with the Sledge STA-1000D.
