Operation Manual

The following steps will help you set up your RSX18A active subwoofer.
• Unpack the RSX18A and included
components. Be sure to save the packaging in
case you ever move, or need to send the unit
for service.
• Set the RSX18A subwoofer and satellite
speaker(s) appropriately for the performance
venue. The RSX18A has a 1 3/8" speaker
pole receptacle, so you can mount a satellite
speaker on top of the RSX18A using a satellite
mounting pole (such as the Samson TS20).
• Turn the Level control on all speakers fully
counterclockwise.
• Turn the Power switch to the OFF position on
all speakers.
• Connect a line-level signal from your mixer (or other source) to the XLR Input jack
on the RSX18A. If you are using a single subwoofer with stereo satellite speakers,
connect the left and right output of the mixer to the stereo XLR Input jacks on the
RSX18A.
• Connect an XLR cable from the High Pass output of the RSX18A to the line input
of your satellite speaker(s).
• Plug the supplied power cable into an AC outlet.
Note: Always make sure that the AC outlet used with this unit is configured with
the correct voltage, as indicated on the rear panel of the RSX loudspeaker.
• Turn the Power switch on your RSX18A and satellite speaker(s) to the ON position.
• Run an audio signal (like music from a CD) from your mixer, and check that you are
getting good level using the mixer's output meter.
• Slowly raise the satellite speaker(s) level control until you have reached a comfortable
level. Then raise the RSX18A Level control until you have reached a level that sits
well within the rest of the mix.
• If the volume from the RSX18A gets too loud, or you notice the Peak indicator
blinking frequently, turn down the Level control on the RSX18A a little until the
Peak indicator does not light, or only lights occasionally with signal peaks.
