Introduction  
Welcome to Samson Expedition—the portable audio system for the new millenium! This  
exceptionally versatile system offers the perfect solution wherever you need portable,  
high-quality audio: as a main PA system or as onstage monitors in clubs and  
performance halls; in houses of worship; as a sound system for business presentations,  
mobile DJs at parties, or aerobics instruction; and for use in outdoor environments such  
as parks, beaches and flea markets. What’s more, every Expedition system comes with  
a built-in telescoping handle and locking wheels, making it easy to take professional  
audio with you wherever you go!  
There are three different Samson Expedition systems detailed in this manual. All utilize  
the same lightweight yet rugged two-way speaker enclosure that pairs a custom  
designed 12" woofer with a matched 1" compression driver. The Expedition EX10 is a  
passive 8-ohm enclosure that can be used with any external power amplifier rated at up  
to 250 watts. The Expedition EX20 is a powered version that includes a bi-amped power  
cell along with an active crossover, speaker protection circuitry and built-in limiting. And  
the Expedition EX30 is designed as a total all-in-one portable PA system, adding a four-  
channel stereo mixer—complete with digital effects—to the equation. In addition, a  
number of expansion options are available, including a 500-watt active subwoofer (our  
EX500); a rechargable Lead-Acid GelCel battery pack; and a rear-panel mountable  
cassette recorder with pitch control. There's even a prewired custom compartment that  
accommodates any of three different Samson wireless receivers!  
In this manual, you’ll find a more detailed description of the features of all three  
Expedition systems, as well as a guided tour through all components, step-by-step  
instructions for setting up your system and full specifications. If your Expedition was  
purchased in the United States, you’ll also find a warranty card enclosed—don’t forget  
to fill it out and mail it! This will enable you to receive online technical support and will  
allow us to send you updated information about this and other Samson products in the  
future. If your Expedition system was purchased outside of the U. S., contact your  
local distributor for warranty details. Also, be sure to check out our website  
SPECIAL NOTE for U.S. purchasers: Should your Expedition system ever require  
servicing, a Return Authorization number (RA) is necessary. Without this number, the

The Samson Expedition system uses state-of-the art  
technology to bring a revolutionary new degree of  
flexibility and portability to professional audio. Its  
main features include:  
A built-in telescoping handle and locking wheels  
that make it easier than ever before to transport  
your audio system.  
All Expedition enclosures are lightweight and  
compact yet exceptionally durable and  
roadworthy. Injection-molded with Polypropylene,  
they feature substantial internal bracing to support  
a nearly 1/2" thick side wall construction, making  
them strong and rigid enough to allow maximum  
energy to be delivered to the sound output.  
In addition, a steel grill and scuff-resistant  
textured finish makes for a rugged speaker  
enclosure that will deliver dependable  
S
A M S O N  
performance in even the most demanding  
environments.  
The low frequency section includes a custom  
designed Kevlar-impregnated 12" low frequency  
driver with a 2.5" Kapton Former voice coil and  
50 ounce barium ferrite magnet for accurate and  
super-tight bass response.  
A high frequency section that delivers clear,  
sweet top end thanks to its 1" compression driver  
with a specially designed phenolic diaphragm,  
along with a phasing plug for linear response and  
an elliptical wave guide horn design that reduces  
nearly all sonic diffraction.  
A tilt position that allows the Expedition to be used  
as an onstage wedge monitor.  
Integral 1 3/8" pole-mount receptacle and convenient fly points allow the  
Expedition to be pole-mounted or flownusing standard PA hardware.  
The EX10 is a passive cabinet that can be used with any power amplifier  
rated at up to 250 watts into 8 ohms. It requires no power and provides  
dual Speakonand 1/4" connectors that allow multiple EX10s to be  
daisy-chained where extended coverage is required.  
The EX20 contains dual power amplifiers and an active crossover.  
Operating in a biamped configuration, one power amp drives the low  
frequency section with 150 watts of power and the other drives the high  
frequency section with 50 watts of power. The active crossover uses an  
advanced Linkwist-Riley constant phase filter that provides a steep rolloff of  
24 dB per octave to reduce sonic distortion at the crossover frequencies.  
Dual balanced XLR connectors allow daisy-chaining of multiple Expedition  
enclosures, and a switchable limiter circuit assures a clean output even  
when youre pushing the EX20 to maximum levels. In addition, there are  
three stages of speaker protection, including relay switching for power on  
and off.

The EX30 includes all the features of the  
EX20, and adds a flexible four-channel  
stereo mixer that provides two  
monophonic and one stereo mic/line  
channels with dual XLR and 1/4"  
connectors. In addition, separate dual  
phono connectors allow you to hook up  
an external cassette or CD player.  
Each mixer channel includes two-band  
equalization and independent volume  
control, and theres even built-in digital  
effects for the addition of six different  
reverb presets. Balanced left and right  
XLR outputs allow daisy-chaining of  
multiple Expedition speakers (with a  
mono/stereo switch that allows operation  
in either mode), and a VU meter enables  
you to continuously monitor output levels.  
The EX20 and EX30 also include a meter  
that shows battery level when used with  
the optional RB 2030 rechargable battery  
cartridge (see below).  
The top panel of both the EX20 and  
EX30 provides a prewired compartment  
that accommodates a variety of Samson  
wireless systems that offer superior RF  
and audio performance already proven  
on stages around the world. Receivers  
supported include the UM1 or M32 UHF  
models or the VM1 VHF model.  
A wide range of optional accessories,  
including: the MP 1030 mounting bracket,  
which allows any Expedition enclosure to  
be flownfrom the ceiling; the RB 2030  
rechargable battery cartridge, which  
provides up to two hours of power to  
either the EX20 or EX30 from its dual  
Lead-Acid GelCel batteries; and the TD30 cassette recorder, which fits neatly into a  
special compartment above the EX30s mixer to provide background music and/or  
to record meetings or performances. The TD30 even includes a pitch control so you  
can alter the tempo of the music for applications like aerobic instruction.  
The EX500 is an active subwoofer that pairs a massive 500-watt amplifier with a  
heavy-duty 15" low frequency driver. It is an ideal complement to any Expedition  
enclosure or any loudspeaker system, when the application requires deep, powerful  
low end response. Its built-in stereo electronic crossover allows the EX500 to  
operate either in mono or as a common subwoofer in a stereo system. It features  
an all-steel grill and rigid corners, as well as an integral pole mount.

Expe dition EX30  
Guide d Tour  
1: Equalizer - These controls allow you to shape your sound by boosting or  
cutting the amount of bass (at 100 Hz) or treble (at 10 kHz) by up to 15 dB.  
A center detent in each knob indicates no boost or cut (that is, flat response).  
As each knob is turned clockwise from the 12 oclock position, the bass or treble  
is boosted; as it is turned counterclockwise from the 12 oclock position, the bass  
or treble is reduced.  
2: Reverb send - These knobs determine how much signal is being sent from  
the channel to the onboard DSP effects processor. As you move the knob clock-  
wise from 0 to 10, more signal is sent. To hear the effect, one of the six presets  
must be selected using the DSP Effects control (see #10 on the next page). Be  
careful not to send too much signal to the DSP, or a distorted sound will result.  
2
3: Pan/Balance control - In channels 1 and 2, this knob acts as a Pan control,  
allowing you to place the signal anywhere in the left-right stereo spectrum, while  
keeping the overall signal level constant. When the knob is placed at its center  
(detented) position, the signal is sent equally to both the left and right outputs.  
To route a signal hard left or right, place the pan knob either fully counterclock-  
wise or fully clockwise.  
In channel 3/4 (the stereo channel), this knob acts as a Balance control, allowing  
you to alter the relative levels of the two input signals. When the knob is placed  
at its center detented position, both signals are at equal strength. When moved  
left of center, youll hear more of the left input signal; when moved right of center,  
youll hear more right input signal.  
4: Channel volume control - This knob determines the level of the channel  
In stereo channel 3/4, this knob simultaneously controls the level of both inputs  
(the relative levels of the two can be adjusted with the Balance knob, as  
described in #3 above). In practice, youll use the channel volume controls to  
continuously adjust the levels of the various signals being blended together by  
the EX30 mixer.

Expe dition EX30  
5: Insert (sub) connector - This 1/4" connector brings line-level signal in directly before the  
EX30 power amplifiers. It is normally used to return signal from an optional EX500 subwoofer.  
6: Line inputs - Use these 1/4" jacks to connect line-level sources to the EX30. Channels 1 and  
2 are mono 1/4" connectors; channel 3/4 uses a stereo (TRS) 1/4" connector, with tip carrying left  
signal and ring carrying right signal. Stereo devices should always be connected to the stereo  
channel (channels 3/4). If a wireless receiver is connected to the EX30 via its internal  
connectors (see page 14 in this manual), its output arrives at channel 2, which can also carry  
another line-level source connected to its line input, as well as signal from a microphone  
connected to its mic input. If an optional TD30 cassette player is installed, its output arrives at  
channels 3/4, which can also carry another two line-level sources (one connected to its line input  
and a second connected to the CD inputs [see #15 on the following page]), as well as signal from  
a microphone connected to its mic input.  
7: Mic inputs - Use these XLR jacks to connect microphones to the EX30s built-in mic  
preamps. Each channel can carry both one or more line level sources (see #6 above) as well  
as a mic source.  
8: DSP Effects control - Use this to select one of six reverb presets (Small Hall, Medium Hall,  
Large Hall, Church, Stadium, or Plate). If you dont want to hear any reverb, set this switch to the  
Offposition.  
9: Mono/Stereo switch - When using one EX30, set this switch to Monoso that the EX30  
power amp receives signal from both the left and right output sections. When using multiple  
Expedition speaker enclosures, set this switch to Stereo; the EX30 will then reproduce only  
signal from the left output section only (that is, signals panned left at the mixer); the Right output  
can then be used to send signal from the right output section (that is, signal panned right at  
the mixer) to a second enclosure. See the interconnection diagrams on pages 10 - 11 for more  
information.  
10: Outputs - The dual XLR connectors carry line-level output signal from the EX30. They are  
used to send signal to a second EX30 (or EX20) being daisy-chained (see the interconnection  
diagram on the following page) or to an optional EX500 subwoofer. Note that the signal being  
output from these connectors is dependent upon the setting of the Mono/Stereo switch (see #9  
above). When set to Stereo,the Left XLR connector carries left signal only and the Right XLR  
connector carries right signal only; when set to Mono,both the Left and Right connectors carry  
the same monophonic signal, summed from both the left and right output sections. See the  
interconnection diagrams on pages 10 - 11 for more information.  
11: Main Volume control - This knob determines the final output signal levelyou can think of  
this as being the master fader.Signals from all four channels are routed here just before being  
routed to the EX30s built-in power amplifiers and Left and Right output jacks (see #10 above).  
12: Battery VU meter - If an optional RB 2030 rechargable battery pack is installed, this meter  
shows how much battery power remains as it is being charged (Power switch off) or depleted  
(Power switch on). See #20 on the following page.  
13: Output VU meter - This three-segment bar meter shows the continuous output level of the  
EX30. For optimum signal-to-noise ratio, try to adjust all channel and main Volume controls so  
that program material is usually at or around 0 VU, with occasional but not steady excursions to  
the red +3 dBsegment.  
14: Limiter LED - Lights whenever the built-in limiter is active. If you see this lighting frequently,  
it means youre overloading the EX30, so turn down one or more of the Channel volume controls  
(see #4 on the preceding page) or the main Volume control (see #11 above).

Expe dition EX30  
15: CD inputs - Connect the outputs of a CD or tape player to this set of dual phono  
jacks. Signal arriving here returns to stereo channel 3/4. If an optional TD30 cassette  
player is installed, note that its output also arrives at channels 3/4, in addition to line-level  
signal arriving at its 1/4" TRS line input (see #6 on the preceding page) and signal from a  
microphone connected to its mic input (see #7 on the preceding page).  
16: AC input - Connect the supplied heavy-gauge 3-pin IECpower cable here.  
17: Limiter switch - Use this switch to turn the built-in limiter circuitry on or off.  
In order to maximize speaker protection, we recommend that this switch be left in the  
onposition during normal operation.  
18: Voltage selector - Make sure this is set correctly for the country you are in before  
turning on the power to the EX30.  
19: Gain switch - Sets the line-level TRS input of channel 3/4 (see #6 on the preceding  
page) to either +4 (professional) or -10 (consumer) level.  
20: Power switch - Use this to turn power to the EX30 on or off. If an optional  
RB 2030 rechargable battery pack is installed, it will charge when this switch is in the  
Offposition.  
Inte rconne cting the EX30  
Using one EX30: In this example, microphones are connected to the XLR mic inputs of  
channels 1 and 2, and a stereo keyboard is connected to the stereo 1/4" TRS connector  
of channel 3/4 (using a Y-cord, with the tip carrying the left signal and the ring carrying  
the right signal). IMPORTANT NOTE: When using just one EX30, always be sure to  
set its Mono/Stereo switch to Mono.”

Pos itioning and Mounting Ins tructions  
Ge ne ral Pos itioning Tips  
Operating a microphone or turntable in front of a speaker is a sure formula  
for feedback and/or rumble problems, so always place the Expedition in  
front of any mics or turntables that are being used.  
Use the Expedition upright for all front-of-housePA applications;  
use it in its tilt-back position only for onstage monitoring.  
Always raise the speakers as high above the audience as is practicable  
for maximum coverage.  
Use sufficient enclosures for the space youre in. The larger the space,  
the more speakers will be required.  
Pole -Mounting  
The underside of the Expedition contains a 1-3/8" stand mount socket that  
allows it to be raised up on any standard speaker pole mounting (such as the  
Ultimate Support Systems TS-30 or TS-33 speaker stands). Pole-mounting is  
generally advisable when you want to maximize the distance that the  
Expedition covers (sometimes called speaker throw).  
If you are using an EX500 subwoofer, you can use its integral pole mount to  
place an EX10, EX20 or EX30 immediately above it, creating a complete  
column of sound.  
Fly Mounting, Wall Mounting, and Ce iling Mounting  
As shown in the illustration below, the top panel of the Expedition contains a  
number of fly points, located in compartments to the left and right of the  
wireless receiver compartment. The covers placed over these compartments  
are simply attached with double-sided sticky tape, so just pull up to remove.

Pos itioning and Mounting Ins tructions  
Before fly-mounting, wall-mounting or ceiling-mounting the Expedition, you must  
first install a Samson MP 1030 mounting bracket to the fly points, as shown in the  
illustrations on the right  
Standard cabling and hardware can then be attached to the MP 1030 mounting  
bracket in environments where the Expedition needs to be flown.”  
In fixed installations where you wish to mount the Expedition to a ceiling, use the
