PinWoofer JJP KOP Amplifier Installation Instructions

Air FlowAir Flow
Amplifier Placement
•Remove the Coin Box and replace it with
the amplifier resting as shown.
•Use only a PinWoofer supplied Amplifier
Mounting Bracket. Aside from being more
secure, it will allow you to transport your
machine with the amplifier installed into
the bracket.
•Alternatively, a high-bond double-sided
tape can be used to secure the amplifier
to the Cabinet Floor, or adhesive hook
and loop pads. In this case, please
remove amplifier before transport.
•Mount the amplifier only within the
machine; DO NOT attempt to mount the
amplifier external to the machine.
•The Aluminum Amplifier Enclosure is
designed to have a small convective
airflow underneath to promote cooling.
•The Amplifier should never run more
than slightly warm to the touch.

Harness Routing
•Unplug the machine from AC Power.
•Open the Coin Door.
•Remove the Playfield Glass.
•Lift the Playfield and prop it up.
•Remove the backglass.
•Feed the Amplifier End of the PinWoofer
Harness down and through the
rectangular hole in the right side of the
backbox, into the cabinet, then route the
remainder down the interior of the
cabinet and through the Coin Door
opening as shown.
•Leave approximately 12in (about a 4in to
5in circular loop) of slack at the position
shown. This will provide enough extra
cabling to allow the backbox to be closed
later without stressing the harness.
•Using a cable tie, anchor the wiring
harness to a wire loom near the right-
hand side of the backbox. Doing so “pins”
the wire harness in the backbox so that
the slack loop will be taken up if the
backbox is lowered to its closed position.

Power Connection
•Unplug the 10-Pin Factory
Connector from J110, if it exists.
•Plug the 10-Pin Factory
Connector into the JJP Power
Board.
•Plug the PinWoofer Harness 2-
Pin Power Connector into the
Power Board.
•Plug the Power Board into J110.
•Connect the ground wire to the
backplane screw location as
shown. The ground wire crimp
loop must make contact to
ground or else the power board
will not function.
•Secure Harness Power Cable
Wiring to nearby Wire Looms
and use Cable Ties to relieve any
cable tension on the Power
Board.

When first powering on your PinWoofer Amplifier, adjust the controls as shown:
•“Bass Vol” set to “6 o’clock”
•All other controls set to “12 o’clock”
LED Power Indicator

•After installation, turn the machine on and follow the below startup procedure:
1. Set the service Menu Volume (using coin door volume buttons) to 25.
2. Set the amplifier dials as shown on the previous page.
3. It is likely that the starting amplifier settings from 2. above may not sound good. Be confident in
rotating the dials to any position that sounds good to you!
4. Further adjust the amplifier controls by starting a game or alternating the volume up/down
buttons. Some titles continue playing or start playing sounds when you enter the VOL menu
during a game.
5. Note that there may be a high voltage lock-out switch (a white pin) on the coin door that needs
to be constantly depressed or pulled out to lock in the on position.
6. Your final adjustments may leave the dials in radically different positions. This is perfectly fine as
long as you have achieved your desired results.
7. As needed, return to the menu to make adjustments to the audio settings. It is often helpful to
change the MIX settings depending on results, and after you have had some experience with
your new PinWoofer sound system.
8. Many titles have suggested initial settings at PinWoofer.com in the blog. Visit our blog at
https://pinwoofer.com/blog/ or search the game title in the upper right-hand corner of the web
page.
