Getting Started
The following steps will help you set up your
subwoofer(s) quickly.
INITIAL SETTINGS:
1. Turn the LEVEL control on the rear panel all the
way down.
2. Turn the POWER switch OFF.
CONNECTIONS:
1. Connect the line-level signal from a mixer (or other
signal source) to the INPUT jack on the TH-18s rear
panel (XLR connector). If you are operating the
system in stereo, connect INPUT B, as well.
2. Connect the supplied AC power cord to the IEC
socket on the back of the subwoofer. Plug the other
end into an AC outlet properly configured with the
correct voltage as indicated just above the IEC
socket.
TURN IT ON:
1. Turn the POWER switch ON.
2. Start your signal source (mp3 player, CD, DAW,
band, or whatever), but leave the master level
control on your mixer down.
3. Slowly turn up the LEVEL control on the TH-18s to
the “U” (unity gain) mark at the center position.
4. Adjust the master volume on your mixer to a
comfortably loud listening level. If the volume from
the subwoofer gets really loud, really fast, try turning
down the LEVEL control on the TH-18s a bit. If
the subwoofers don’t get loud enough, turn up the
LEVEL control to achieve a good balance of master
volume control and loudness from the subwoofer.
Now that you have your subwoofers working, it’s time
to hunker down and read the rest of this manual…
especially the following:
