This lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the
user to the presence of non-insulated “dangerous voltage” within the product’s enclosure that
may be of sufficient magnitude to constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence
of important operating and maintenance instructions in the literature accompanying the appli-
ance.

Read these instructions.
Keep these instructions.
Heed all warnings.
14. Refer all servicing to qualified service personnel.
Servicing is required if the apparatus has been
damaged in any way, such as power-supply cord
or plug breakage, damage due to liquid or objects
falling onto the apparatus, exposure to rain or
moisture, or if the apparatus does not operate
normally, or has been dropped.
Follow all instructions.
This apparatus shall not be exposed to dripping
or splashing liquid and no object filled with
liquid, such as a vase, should be placed on the
apparatus.
15. POWER ON/OFF SWITCH: For products with a
power switch, the power switch DOES NOT break
the connection from the mains.
6.
7.
Clean only with a dry cloth.
16. MAINS DISCONNECT: The plug should remain
readily operable. For rack-mount or installation
where plug is not accessible, an all-pole mains
switch with a contact separation of at least 3 mm
in each pole shall be incorporated into the electri-
cal installation of the rack or building.
Do not block any of the ventilation openings.
Install in accordance with the manufacturer's
instructions.

9.
Do not install near any heat sources such as radi-
ators, heat registers, stoves, or other apparatuses
(including amplifiers) that produce heat.
17. FOR UNITS EQUIPPED WITH EXTERNALLY ACCES-
SIBLE FUSE RECEPTACLE: Replace fuse with same
type and rating only.
Only use attachments/accessories specified by
the manufacturer.
10. Unplug this apparatus during lightning storms or
when not in use for long periods of time.
18. MULTIPLE-INPUT VOLTAGE: This equipment may
require the use of a different line cord, attach-
ment plug, or both, depending on the available
power source at installation. Connect this equip-
ment only to the power source indicated on the
equipment rear panel. To reduce the risk of fire or
electric shock, refer servicing to qualified service
personnel or equivalent.
11. Do not override the intended purpose of the po-
larized or grounding-type plug. A polarized plug
has two blades, with one wider than the other. A
grounding-type plug has two blades and a third
grounding prong. The wide blade, or third prong,
is provided for your safety. If the provided plug
does not fit your outlet, consult an electrician to
replace the obsolete outlet.
12. Protect the power cord from being walked on or
pinched, particularly at the prongs, convenience
receptacles, the point where they exit from the
apparatus.
13. Use only with the cart stand, tripod bracket, or
table specified by the manufacture, or sold with
the apparatus. When a cart is used, utilize caution
when moving the cart/apparatus combination to
avoid injury from tip-over.

Introduction
Thank you for purchasing the Samson Expedition professional, powered loudspeaker. The
Expedition XP112a and XP115a are compact and powerful speaker cabinets featuring
500 watts of bi-amped onboard power. The Expedition XP112a and XP115a, respectively,
feature 12”and 15”heavy-duty, long-excursion woofers, as well as 1”neodymium high
frequency driver on 1”throat wide dispersion horns. The speaker cabinets provide both
XLR and ¼”phone jacks that handle microphone or line level inputs. The XLR Line Output
allows you to “daisy-chain”multiple Expedition cabinets together to create larger sound
reinforcement systems.
Each cabinet’s trapezoidal shape allows it to be configured for either front-of-house use,
or for operation as a wedge-style monitor. In addition, the compact cabinets can easily
be stacked, using the built-in bumpers or can be stand-mounted using the integral 1 3/8”
pole-mount receptacles.
Each Expedition PA system’s durable enclosure is made of high-impact polypropylene
with a scuff-resistant textured finish, and include a heavy-grade steel grill, offering excel-
lent protection against wear and tear for truly portable audio. The Expedition active mon-
itors are ideal for live music, DJ, lecture, and installed sound applications, or anywhere
serious power and superior sound quality are desired.
In these pages, you’ll find a detailed itemization of the features of the Expedition 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 that we can send you updated information about this and other Samson products in
information about our full product line.
We recommend you record your serial number in the space provided below for future
reference.
Serial number:_____________________________________
Date of purchase: ___________________________________

Positioning the Expedition XP112a/XP115a
Speaker Placement
Whenever possible, it is a good idea to raise the
speakers above the heads of the listening audience.
The Expedition enclosures feature standard 1 3/8”
pole mount receptacles with locking bolts, 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 Expedition loudspeaker in the tilt back monitor
positions, which will improve the projection of the
speakers and may eliminate the need for speaker
stands.
Note: When using a speaker pole mount, be sure
the pole is capable of supporting the weight of the
Expedition loudspeaker.
Note: Always have another person to assist when
mounting the Expedition speaker onto a speaker
stand, or when adjusting the stand while the speaker
is mounted on the stand.
Floor Monitor
The Expedition XP112a/XP115a is an ideal solu-
tion for stage monitoring thanks to its wedge
monitor positions. When placed on its side, with
the high frequency horn facing to the right of
the enclosure, the Expedition is tilted at a 45
degree angle, optimizing performance when
used on a stage.
