1. XLR and ¼” Input Connector (Input 1) - This combo
XLR and ¼” connector accepts either a balanced
or unbalanced microphone or line level signal.
The ¼” phone input accepts TS or TRS type
connectors.
2. VOL Control (Input 1) - This Volume knob adjusts
the level of the Input 1 channel.
3. Mic/Line Switch (Input 1) - The MIC position
changes the gain of the Input 1 jacks to MIC
level. The LINE position reduces the gain of both
jacks by 30dB to line level.
4. XLR and ¼” Input Connector (Input 2) - This combo
XLR and ¼” connector accepts either a balanced
or unbalanced line level signal. The ¼” phone
input accepts TS or TRS type connectors.
5. VOL Control (Input 2) - This control adjusts the
level of the Input 2 channel.
6. STATUS Indicator - This bi-color LED lights
GREEN when signal is present at the inputs,
regardless of the input volume control settings.
The indicator lights RED when the amp is near
the clipping point and the limiter is engaged.
If the LIMITER indicator lights frequently, turn
down the INPUT volume controls on the speaker
or turn down the signal at the source, until the
indicator does not light anymore, or lights only
occasionally with high signal peaks.
7. POWER Indicator - The POWER LED lights
indicating that the main POWER switch is on.
8. DSP PRESET - The RSX DSP has three EQ contour
curves: FLAT, BOOST, and VOCAL. The FLAT
setting produces the standard frequency response
and works best for most applications. The BOOST
setting enhances low frequencies to add punch
and high frequencies to add vocal clarity. The
VOCAL setting provides a high frequency lift
for vocal clarity. This is useful when plugging a
microphone directly into the speaker.
9. FRONT LED Switch- When set to the ON position,
the front power LED will illuminate when the
Power LED switch is set to the ON position. When
the switch is in the OFF position, the Front Power
LED will not illuminate.

10. MIX Output - Male XLR connector used to link multiple speaker cabinets.
NOTE: When connecting a loudspeaker to the Line Output of the RSX loudspeaker, it is important to
power on the RSX loudspeaker first, then power on the linked speaker. When powering down the
system, it is recommended to turn off all linked speakers, then power off the RSX loudspeaker.
11. Power Switch - This rocker switch turns on and off the speaker’s main power. The switch lights
RED when the amp is active.
NOTE: It is important to remember the Golden Rule of audio… “LAST ON, FIRST OFF.” Translated, this
means that when turning on your system, you should always turn your powered speakers on LAST, and
when turning your system off, turn your powered speakers off FIRST. This helps avoid any loud pops
caused by inrush current at power up, or down, which can sometimes damage loudspeakers.
12. AC Power Inlet - Connect the supplied standard 3-prong IEC power cable here.
Note: Never disconnect the plug’s ground pin. It is dangerous and can result in electric shock!
13. Fuse Cover - The fuse is located behind the fuse cover. Always replace fuses with the same type of
fuse.
14. Voltage Selection Switch - This switch is used to select the amplifiers operating voltage.
NOTE: Before using your speaker, be sure the voltage selection switch is set to the correct voltage
for your country. Be sure to install the properly rated fuse when changing the operating voltage.

Positioning RSX Loudspeakers
Speaker Placement
The RSX Active Loudspeakers feature standard 13∕8"
pole mount receptacles, which enable the speaker to
be mounted on a standard tripod stand or subwoofer
satellite pole. For best results, raise the speakers
above the heads of the listening audience.
When mounting a speaker onto any stand, always
ensure that the stand is on a flat, level surface,
with the legs fully extended. Be sure to check that
the maximum load weight for the stands is greater
than the weight of the RSX loudspeaker. Never
use a stand with a maximum load weight less than
the speaker weight. Do not attempt to mount more
than one speaker on a stand at one time. The RSX
loudspeakers are heavy. It is recommended to have a
second person help place the cabinet on a stand.
When the speaker is placed on a stand, always check
the integrity and center of gravity of the system.
If the speaker can be tipped easily, or the pole is
swaying, it is recommended that you lower the height
of the stand. Position the stand and route cables so
that the performers and the audience cannot tip over
or trip on the system.
When using the RSXM10a and RSXM12a on
a speaker stand, it is recommended to set the
MONITOR/FOH switch in the FOH (Front of House)
position for optimal frequency response.
Using the RSX112a/RSX115a as a Floor Monitor
The RSX112a/RSX115a cabinet design features
integral 45° monitor angles, controlled bass frequency
reproduction, and clear high frequency sound, making the
RSX112a/RSX115a ideal for stage monitoring applications
or whenever a performer needs to direct sound to their
ears.
In a large stage monitor system, several RSX112a/
RSX115a speakers can be daisy-chained together using the
parallel speaker connectors.
In many instances, when using the RSX speakers as
a monitor system, you may choose to use an external
equalizer to tailor the sound to cut through the stage levels
and to reduce the chance of feedback.

Positioning RSX Loudspeakers
Positioning the RSXM10a/RSXM12a Floor Monitors
The RSXM10a/RSXM12aspeakersare ideal solutions for
stage monitoring thanks to its uniquecompact,low-profile
design. In a large stagemonitor system, several speakers
can be daisy-chainedtogether using the Line Output.
When positioning themonitor, be mindful of the placement
of your microphonesto help reduce feedback problems.
It’s a really good idea toknow your microphone’s pick up
pattern to choose the rightspot. Some microphones, like
super and hyper-cardioidmodels, offer a lot of rejection in
the rear of their pick uppattern and when the RSXM10a/
RSXM12a is positioned at the sameangle as the rejection,
you can set the monitor a lot louderbefore it feeds
back. In many instances you may choose to
use anexternal equalizer to increasethe
volume and reduce the chance of
feedback.
When using the RSXM10a and
RSXM12a on a speaker stand, it is
recommended to set the MONITOR/FOH
switch in the MONITOR position for optimal
frequency response.
Avoiding Feedback
Feedback is the annoying howling and squealing that can heard when the microphone picks up sound
from the speaker. The sound is then re-amplified back through the speaker again, creating a feedback
loop. Follow these steps to minimize the likelihood of feedback:
• Avoid pointing microphones directly at the speaker. In general it is recommended that the micro-
phone be positioned behind the speaker enclosure. This uses the directional characteristics of the
speaker and microphone to your advantage.
• Keep the microphone as far from the speaker as possible. This will help achieve isolation between
the speaker and the microphone, and allow you to increase the output of the RSXLoudspeaker.
• Position the microphone as close to the sound source as possible. This will enable the microphone
to pick up more direct sound, and allow you to reduce the microphone input gain control.
• Reduce the overall level of the speaker.

Permanent Installation
The RSX112a and RSX115a loudspeakers are perfect solutions for
many fixed installations such as live sound venues, discos, schools,
houses of worship, convention centers and airport terminals. The twoway speaker enclosures are extremely versatile for installation as they
can be suspended in several different positions by using the twelve fly
points.
IMPORTANT NOTE: Suspending an RSX loudspeaker should only be
done by a qualified, licensed and insured professional sound contractor. Installation in an unsafe manner or location can result in property
damage and serious injury. When installing the speaker, make sure
all local ordinances are understood and adhered to. Always check and
ensure that whatever structure the speaker is mounted to is devoid of
cracks, deformations, or any signs of fatigue.
The RSX speakers are designed to be mounted directly to a structure.
Never suspend an RSX cabinet from another speaker, and do no suspend another speaker from an RSX cabinet.
When suspended, always affix a safety cable from the RSX cabinet to
the mounting structure.
A minimum of two (2) attachment points must be used when suspend-
ing the speaker enclosure. The rear and side attachment points are
only used as pull-back points to adjust the angle of the speaker. Only
the top and bottom fly points are load-bearing suspension points.
When suspending the RSX cabinet, it is recommended that you use
an eyebolt, thimble, and shackle along with wire rope.
