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 fourchannel 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 (http://www.samsontech.com) for complete information about our full product line.

SPECIAL NOTE for U.S. purchasers: Should your Expedition system ever require servicing, a Return Authorization number (RA) is necessary. Without this number, the unit will not be accepted. If your Expedition system was purchased in the United States, please call Samson at 1-800-372-6766 for a Return Authorization number prior to shipping your system. If possible, return the unit in its original carton and packing materials. If your Expedition system was purchased outside of the U. S., contact your local distributor for information.

System Features

SAMSON

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 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 “flown” using 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 Speakon™ and 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 you’re pushing the EX20 to maximum levels. In addition, there are three stages of speaker protection, including relay switching for power on and off.

System Features

• 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 there’s 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 “flown” from 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 EX30’s 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.
