Getting Started

The following steps will help you set up the
subwoofers quickly.
1. Make all initial connections with the power
switches OFF on all equipment. Make sure the master
volume, level, or gain controls are all the way down.
2. Connect the line-level outputs from the mixing
console (or other signal source) to the XLR inputs on
the rear panel of the Thump18S subwoofers.
3. Connect the high pass outputs from the Thump18S
subwoofers to the inputs of powered loudspeakers
(or to an amplifier powering passive loudspeakers).
4. Connect the supplied AC power cords to the
IEC sockets on the rear panel of each subwoofer.
Plug the other end into an AC outlet properly configured
with the correct voltage as indicated below the IEC
socket.
5. Turn the mixer (or other signal source) on.
6. Turn the subwoofers on.
7. Turn the loudspeakers on.
8. Start the signal source and raise the mixer's
main L/R fader up until audio may be heard.
9. Adjust the master volume of the mixer to a
comfortably loud listening level.

Things to Remember:

• Never listen to loud music for prolonged periods.
Please see the Safety Instructions on page 2 for
information on hearing protection.
• As a general guide, the mixer (or other signal
source) should be turned on first, Thump18S
subwoofers next, and loudspeakers last. As such,
the loudspeakers should also be turned off first,
followed by the subwoofers, then the mixer.
This will reduce the possibility of any turn-on
or turn-off thumps and other noises generated
by any upstream equipment from coming out of
the speakers.
• Save the shipping boxes and packing materials!
You may need them someday. Besides, the
cats will love playing in them and jumping out at
you unexpectedly. Remember to pretend like you
are surprised!
• Save your sales receipt in a safe place.
