Thank you for purchasing the Expedition EX500 Subwoofer by Samson. The EX500 is a self- powered, 500 Watt subwoofer featuring a 15” heavy duty driver, complemented by a 500 Watt, lightweight, Down Tracking Amplifier. The EX500 also offers an active stereo crossover providing a high-passed output for running your satellite speakers. Solid 3/4 inch plywood construction, steel corners, tough carpet covering and larger casters make the EX500 a road warrior. In fixed installation systems, the EX500 provides super tight low fre­quency output in a relatively small, unobtrusive enclosure. The EX500 is a perfect add-on to your Expedition system, or for any sound reinforcement system where extended low-end is desired. While using your Expedition EX500, you’ll have great low-end anywhere.
In these pages, you’ll find a detailed description of the features of the EX500 Subwoofer, as well as a guided tour through 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.

Configuring Your Speaker System

Before you start plugging in cables, you should take a minute to decide how you want to interface your new sub­woofer. There are several ways you can interface the EX500, however most systems set-ups fall into two cate­gories, Stereo or Mono (Common) sub operation.
Stereo Sub Operation
In larger rooms, as well as in theatres and theme park installations (for low frequency special audio effects), two EX500’s can be used in stereo.
Common Sub Operation
In most cases a common sub, or mono bass operation is desired. This is true for several reasons, but mostly because low frequencies produced by a subwoofer tend to be non-directional. Since low frequency waves take so much space to actually develop, you can’t tell if the sub bass is coming from the left or right side, unless of course you’re in a very large room. Because of this phenomena, just about all sub bass material is mixed in mono.

Operating the EX500

Level Control
The level control is used to adjust the amount of volume from the EX500 subwoofer. In addition, the Level control will also control the output volume of the high-passed outputs. Therefore, if you are using the EX500 without using the high-passed outputs (for example, when the EX500 is connected to an external crossover) the Level control adjusts the low frequency output of the EX500. If you are using the EX500’s internal elec­tronic crossover to run satellite speakers, then the Level control will adjust the overall system vol­ume.
Sweep
The Sweep control selects the upper range cutoff frequency of the EX500’s internal electronic crossover. The EX500’s crossover provides a 12dB per octave Linkwisz- Riley filter curve. The Sweep limits the high frequency that the EX500 will reproduce, and at the same time, the high-passed output tracks the selected crossover fre­quency as the lower limit frequency.
Stereo / Mono Switch
The Stereo/ Mono switch selects either stereo or mono bass operation. When set to MONO, the EX500 will com­bine, or sum, the left and right signals and send a mono signal to the amplifier of the EX500. In this mode, the original stereo signal is passed through the left and right outputs only now the stereo signal is filtered at the fre­quency set by the sweep control. In Stereo mode, the low frequency signal is not summed, and you can choose either the left or right input accordingly for each side of the system.
The In and The Outs
The EX500 feature electronically balanced inputs and outputs so that any possible HUM problems are greatly reduced when interfacing to other equipment. XLR connectors with industry standard pin- outs are used for easy interface from mixer and other professional audio gear. A detailed wiring diagram can be found in the section EX500 Connections on page 12 of this manual.
The EX500’s control panel provides the connections and user interface to the EX500’s internal electronic crossover and power amplifier section. The internal amplifier is a 500 Watt tracking amplifier capable of producing incredible bass output while running super cool, and at the same time, weighing half as much as conventional power amplifiers. EX500 employs an electronic crossover that adjusts the high frequency cutoff point for the sub­woofer, and also, a high passed output for your satellite speakers. You will achieve a tremendous benefit in sound quality by running your satellite speakers from the EX500’s High-Pass outputs. The reason for this is that when your satellite speaker receives the filtered output from the EX500, it will no longer be looking at the frequen­cies below the crossover point. Let’s say your satellite speaker has a natural frequency roll-off at 70 Hz, and you are sending full range signal (as low as 20Hz) to the satellite amplifier and speaker. Even though the speaker can only reproduce 70Hz and up, the amplifier is still outputting 20-70Hz, which is wasted power and essentially turns into heat. By using the EX500’s High-Pass output, the satellite amplifier and speaker never see the fre­quencies lower than what’s set by the Sweep frequency. This means you’ll have more power dedicated to the frequencies you want the satellites to deliver, resulting in a much cleaner sound with more headroom.

Operating the EX500
The EX500 is a perfect addition to any pair of powered full range enclosures like the Samson EX20 and EX30. Below is a typical system set-up using the EX500 with a mixer and a pair of powered satellite loudspeakers. The EX500’s input and outputs utilize industry standard XLR connectors. For a detailed wiring diagram, see the sec­tion EX500 Connections on page 12. Follow the steps below the diagram to set up your system.

EX500 MONO SUB WITH POWERED SATELLITES

• Connect the mixer’s left output to the EX500’s left
input and the mixer’s right output to the EX500’s right input. Now connect the EX500’s left output to the input of the left side powered satellite, and the EX500’s right output to the input of the right side satellite. Switch the Stereo/Mono selector switch to the MONO position.
• Now adjust the crossover SWEEP to the desired fre-
quency. For the Expedition EX20 & EX30 select 80­100Hz. If you are using another brand of powered speaker as satellites with the EX500, consult their respective owners manuals for the recommended crossover point.
• Lower your mixer’s master outputs to all the way off.
Now set the level of your powered satellites up to the normal operating level. Run an audio signal (like some music from a CD) through your mixer and raise the level to a comfortable listening volume. Now slowly raise the EX500 Level control and listen to the low frequency output. Adjust the EX500 to the level of low frequency output that you like. Now, when you raise and lower your mixer’s output, the EX500 and satellites will track at the same relative volume.

put to the right-side EX500’s right input. Now connect the left-side EX500’s left output to the left input of the power amplifier and the EX500’s right output to the the power amp’s right input. Run your speaker cables from the power amp’s out­puts to the left and right satellite speakers. Switch both the Stereo/Mono selector switches to the Stereo position.
• Now adjust the crossover SWEEP to the desired frequency. For the Expedition EX10 select 80-100Hz. If you are using another brand of speakers as satellites with the EX500, consult their respective owners manuals for the recommended crossover point.
• Set the level of your power amplifiers to the normal operating level. Run an audio signal (like some music from a CD) through your mixer and raise the level to a comfortable listening level. Now slowly raise the EX500 Level control and listen to the low frequency output. Adjust the EX500 to the level of low frequency output that you like. Now when you raise and lower your mixer’s output, the EX500 and satellites will track at the same relative volume.
