WARNING: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture.
The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the
presence of uninsulated "dangerous voltage" within the products enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

Introduction
Congratulations on purchasing the Samson dB500! The dB500 speaker system by Samson takes the concept of
PA systems to a new level. By combining 500 watts of power handling, advanced crossover design and the highest quality speaker and cabinet components, the dB500 provides studio quality sound for any kind of live application. The monitor features a super heavy-duty, custom designed, 15" Celestion® low frequency driver and a 1.75
inch (44 millimeter) titanium diaphragm high frequency driver on a 1" throat, wide dispersion horn. The dB500
offers crystal-clear audio and an ultra-wide sound field. The top end is clean, smooth and vivid. Not only a frontfiring PA speaker, the dB500’s are also designed to operate as wedge-style monitors. The cabinet’s right and left
side panels are joined at different angles, so depending on the side you choose, you get a different dispersion
angle, allowing for greater flexibility on stage. Adding to the dB500’s practical design is a catalog of mounting
options. The compact cabinet can be easily stacked, permanently installed, mounted using the integral 1 3/8"
pole mount receptacle or suspended using the ten built-in fly points. With the dB500, setup and break down is
quick and easy. Heavy-grade steel grills, scuff-resistant textured finishes and rigid corners offer excellent protection against wear and tear. As fixed sound reinforcement or as a durable, great-sounding road PA, the dB500
monitor is ideal for sound professionals and performers looking for serious output and studio monitor sound quality from a PA speaker system.
In these pages, you’ll find a detailed description of the features of the dB500 PA system, as well as a description
of its front and rear panels, step-by-step instructions for its setup and use, and full specifications. You’ll also find a
warranty card enclosed—please don’t forget to fill it out and mail it in so that you can receive online technical support and so we can send you updated information about these and other Samson products in the future.
With proper care your dB500 will operate trouble free for many years. We recommend you record your serial
number in the space provided below for future reference.

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 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 dB500’s, make sure that the power of all your systems components is 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
Connect the cables to your microphones and instruments, or a CD player, to your mixer.
3
Switch on the power of the mixer, instruments and/or CD player, and then switch on
your power amplifier.
4
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.
5
Now, slowly raise your power amp until you reach the desired listening level.

Controls and Functions
Positioning the dB500
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 enclosures. This will give you the best level from your system before feedback.
One possible exception is when you are adjusting the sounds of the
microphones, 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 microphones 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 dB500 enclosure features a standard 1 3/8” pole mount receptacle, which are compatible with speaker
stands from a variety of manufacturers. In a smaller setting like a school
cafeteria, library, or a mall kiosk, you can also use the dB500 in one of
the tilt back monitor positions, which will improve the projection of the
speakers and may eliminate the need for speaker stands.
Using the dB500 as a Floor Monitor
The dB500 is an ideal solution for stage
monitoring and thanks to its unique design,
two wedge monitor positions are possible.
When placed on its side with the high frequency horn facing to the left of the enclosure, the dB500 is tilted at a 15 degree
angle optimizing performance when used
on a small stage. When placed on its side
with the high frequency horn facing to the
right of the enclosure, the dB500 is tilted at
a 30 degree angle optimizing performance
when used on larger stages. In a large
stage monitor system, several dB500’s can
be daisy-chained together using the
EXTENSION SPEAKER output.

your power amplifier to avoid overload and
possible damage to both the speaker and
amplifier. In many instances when using the dB500 as a monitor system, you may choose to use an
external equalizer like the Samson S Curve 131 to increase the volume and reduce the chance of
feedback.

This example shows a typical PA system using mixer with an external power amplifier and a pair of dB500 for the main left and right
mix. A separate signal from the mixer’s AUX/MOINITOR buss is sent to two additional dB500’s place in the tilt-back, wedge positions
for use as floor monitors. In order to increase the output of the monitor system, the use of an external graphic equalizer like one of the
Samson “E” or “S curve” series is highly recommended.

Using Speaker Stands
The dB500 enclosure features a standard 1 3/8”,
pole mount receptacle, which are compatible with
speaker stands from a variety of manufacturers.
Before installing the dB500 on a speaker stand,
loosen the thumbscrew located on the bottom of the
rear side of the enclosure. Once installed on the
stand, be sure to tighten the thumbscrew to hold the
speaker in place. Be careful not to over tighten the
thumbscrew to avoid stripping the threads.
Stacking the dB500
The dB500 enclosure incorporates gender mating
stack feet and bumpers that allows you to stack one
dB500 on top of another. When stacking the
dB500’s, be certain that the rubber feet from the top
unit are securely fastened into the bottom unit’s
stacking bumpers.
NOTE: DO NOT STACK dB500’s OVER TWO (2)

The dB500 is logical solution for many
fixed installations in live sound venues,
discos, schools, houses of worship, convention centers and airport terminals to
name a few. The enclosure is extremely
versatile for installation as it can be hung
in several different positions by using the
10 Fly-points. Hanging the dB500 is serious business and therefore licensed and
insured professional sound contractors
only should perform such an installation.
