Introduction
Congratulations on purchasing the Samson Resound Series loudspeaker system! The Resound speaker systems
by Samson takes the concept of PA systems to a new level. Whether you are using the RS10, RS12, RS15 or
RS215 front-firing PA speakers for main “front of house” PA, or the RS10M, RS12M or RS15M for wedge floor
monitors, the Resound series will provide clear sound with a lot of output. By combining high power handling,
advanced crossover design, along with quality speaker and cabinet components, the Resound series provides
premium audio for any kind of live application. For deep low end that stays tight and punchy, each of the
Resound loudspeakers features heavy-duty, custom designed low frequency drivers. A ten-inch woofer in the
Resound RS10 and RS10M , a 12-inch for the Resound RS12 and RS12M and 15-inch woofers for the RS15,
RS15M and RS215M. To handle the high frequency content, the Resound series employs a 1.75-inch (44 mil-
limeter) mylar diaphragm high frequency driver on a 1" throat, wide dispersion horn. The result, the Resound
series speaker systems offer crystal-clear audio and an ultra-wide sound field. To make your connections simple,
each Resound model provides both 1/4-inch and NEUTRIK SPEAKON® Input and Extension output connectors.
Heavy-grade steel grills and durable carpet covering offer excellent protection against wear and tear. The com-
pact cabinets can be placed on the floor or stand mounted using the integral 1 3/8" pole mount receptacle. With
the Resound, setup and break down is quick and easy. As fixed sound reinforcement or as a durable, great-
sounding road PA, the Resound monitor is ideal for sound professionals and performers looking for serious out-
put and studio monitor sound quality from a PA speaker system.

Connecting the Resound Speaker System
Choosing the Correct cables
The Resound series speakers connections are made via the rear panel 1/4-inch and/or Neutrik Speakon® con-
nectors. Standard unshielded speaker wire, available at your local pro audio or music store, with either 1/4-inch
phone or Speakon connectors and wire gauge of 12-14 is recommended.
If your amplifier uses binding posts you can use speaker cables with banana plugs, but be sure to pay attention to
the plus and minus polarity when making the connections. It is important that your PA system is connected in
phase otherwise you will not have the proper low-end response and stereo image.
In order to ensure that your PA system is in phase, be careful to pay close attention to the positive and negative
marking on the amplifier and wires. Make sure that the + terminal of the speaker, or banana connector, is con-
nected to the + terminal of the power amplifier and that the - terminal of the speaker, or banana connector, is con-
nected to the - terminal of the power amplifier.For a detailed wiring diagram, see page 9 of this manual.
Here’s a tip: It’s fairly easy to identify a monitor that is out of phase just by listening, especially on a pop record.
Listen for the parts of the music that you would expect to be in the center of the mix like kick drum and vocals. If
you do not hear them directly in the center (for instance they sound like they are two signals panned hard right
and left) then you are more than likely listening to an out-of-phase monitor system. (This test won’t work on early
Beatles records where Ringo’s drum kit is panned all the to the right side. Try a Madonna record.)
About Impedance
Before you hook up your speaker cabinet, be sure that you understand a little about impedance. Impedance is
the electronic load that the speaker puts on the power amplifier and is measured in Ohms.
Here is the tricky, yet simple rule of impedance: When two speakers, of equal impedance are wired in "Parallel",
like when you use the Extension Output, the total impedance is cut in half and when two speakers are wire in
“Series”, (usually for interna cabinet wiring only), the total impedance is the sum of the speakers individual imped-
ance.
Each of the Resound models, EXCEPT the RS215 is 8 Ohms. So, when two Resound models, EXCEPT the
RS215 are connected together in parallel, the total impedance is 4 Ohms. The RS215 impedance is 4 Ohms. So,
when two RS215’s are connected together in parallel, the total impedance is 2 Ohms. The impedance of your
speaker also has an effect on your amplifier. In general, the lower the impedance, the more power your amplifier
will put out.
IMPORTANT NOTE: There is minimum safe impedance for running power amplifiers so be sure to check the man-
ufacturer’s recommended impedance for your amplifier to avoid any damage to your amplifier or voiding your
warranty.
Using the EXTENSION Output
The Resound models provide a convenient Extension Output for connecting additional speaker cabinets in paral-
lel. Be sure to read the section above on impedance to insure a proper hook up with your amplifier. To connect
two Resounds using the Extension output, connect your amplifier output to the Input of the first Resound and
then, connect the Extension Output to the Input of the second Resound.
Powering the Resound
Each of the Resound loudspeakers have a specific power rating, which is printed on the input jack-plate, and
also, in the Specification section on page 10 of this manual. Be sure to check that your power amp has the cor-
rect power output for your Resound. Be careful to consider the total impedance if you are connecting more the
one Resound to one side of a stereo power amplifier. Using a power amplifier with too low of a power rating can
be dangerous since the output signal is often clipped in an effort to get the desired level. Over powering the
Resound can result in catastrophic failure and therefore using any amplifier with a power rating over the recom-
mend power rating may void your warranty.

Quick Set-Up
In the following pages of this manual you will find a detailed explanation of system set-ups, but if you
just want to get started quickly, you can follow the diagram and steps below to set up a basic stereo PA
system.
NOTE: Before plugging in and turning on, 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 power amplifiers or powered monitors on LAST, and when turning your system off, turn your
power amps off FIRST. This helps avoid any loud pops caused by inrush current at power up, which
can sometimes damage loudspeakers.
1.
Before connecting your Resound’s, make sure that the power of all your systems components
are turned off. Also, make sure that your power amplifier volume controls and the main left and
right faders of your mixer are turned all the way down.
2.
3.
Connect the cables to your microphones and instruments, or a CD player, to your mixer.
Switch on the power of the mixer, instruments and/or CD player, and then switch on your power
amplifier.
4.
5.
While speaking into the mic (or playing the instrument or CD), raise the mixers main Left and
Right faders to the "0" position. Be sure that the mixer’s output meters are not clipping. If they
are, adjust the mixer volumes down until the signal cleans up.
Now, slowly raise your power amp controls until you reach the desired listening level.

Positioning the Resound
Microphone Positioning - How to Reduce Feedback
Feedback is the annoying howling and squealing that is heard when the
microphone gets too close to the speaker and the volume is high. You get
feedback when the microphone picks up the amplified signal from the
speaker, and then amplifies through the speaker again, and then picks it
up again, and so on and so on. In general, it is always recommended that
any LIVE mic (a mic that’s on) is positioned behind the speaker enclo-
sures. This will give you the best level from your system before feedback.
One possible exception is when you are adjusting the sounds of the micro-
phones, since you want to listen in front of the speaker to hear properly. To
do this, lower the MAIN VOLUME while setting the EQ and effect from in
front of the speakers. Once you have the sound you like, move the micro-
phones to behind the speakers and raise the Main volume.
Speaker Placement
Whenever possible, it is a good idea to raise the speakers above the
heads of the listening audience. The Resound enclosure features a stan-
dard 1 3/8” pole mount receptacle, which is compatible with speaker
stands from a variety of manufacturers.
Using the Resound as a Floor Monitor
The Resound RS10M, RS12M and RS15M are ideal solutions for stage
monitoring and thanks to the unique design of the RS10M and RS12M,
two wedge monitor positions are possible. When placed on its side with
the high frequency horn facing to the left of
the enclosure, the RS10M and RS12M are
tilted at a 25 degree angle optimizing per-
formance when used on a small stage.
When the monitors are placed on their side
with the high frequency horn facing to the
right of the enclosure, they are tilted at a 30
degree angle optimizing performance when
used on larger stages. The RS15M fea-
tures a wide dispersion pattern and is con-
figured with a 30 degree angle making them
ideal for electronic drum and keyboard
monitors. In a large stage monitor system,
several Resound’s can be daisy-chained
together using the EXTENSION SPEAKER
output.

Note: Be sure to check the manufacturers
minimum recommended impedance for
your power amplifier to avoid overload and
possible damage to both the speaker and
amplifier. In many instances when using
the Resound as a monitor system, you may

choose to use an external equalizer like the Samson S Curve 131 to increase the volume and reduce
