Thank you for purchasing the Expedition XP1000 PORTABLE PA SYSTEM from
Samson! The XP1000 delivers the optimum balance between huge, awesome sound
and portability. The system is light enough for one person to carry, and packs togeth-
er into a single unit, making it amazingly easy to transport even in the trunk of a
compact car.
The XP1000 system is comprised of two 10” 2-way speaker cabinets, a 10-channel,
1000 watt powered mixer, and two speakers cables. The powered mixer packs neatly
into the back of one of the speaker cabinets and there is a accessory compartment
behind the second cabinet to hold the speaker and power cables. The two speakers
feature our unique slide and lock design to join together, allowing the entire system
to pack up into a single unit about the size of a carry-on piece of luggage.
The 10-channel mixer can be used while it is stored in the back of the speaker
or removed from the speaker for desktop use. It features 4 inputs for connecting
microphones, plus three inputs for connecting stereo signals, like those from a key-
board or MP3 player. There’s also a built-in, 24-bit digital effects processor to add
studio quality effects to your voice or instruments. For music playback, the XP1000
features wireless Bluetooth®connectivity, to stream audio from your smart phone,
tablet, or computer. The mixer also provides a robust output, with 1000 watts of total
power from the highly-efficient, lightweight, Class D amplifier section.
The XP1000 employs a matched speaker system with dual 2-way enclosures that
have proprietary 10” woofers and 1” high frequency drivers loaded in a 90° x 60°
horn for wide vertical coverage. To project the sound to a larger audience, the
XP1000 speakers can be mounted on standard speaker stands, thanks to the integral
pole mount receptacles. The XP1000 is constructed using durable ABS, high impact
plastic, making it super road tough, and at the same time, lightweight.
The XP1000 is the perfect tool for your solo performance, garage band rehearsal,
cocktail hour act, boardroom presentation, or classroom lecture. In this manual,

1. Channel Input Jacks (channels 1 - 4)
MIC – XLR connector – Use these XLR jacks to connect low impedance microphones
to the XP1000’s built-in mic preamps.
LINE - ¼” phone connector – Use these ¼” jacks to connect instrument or audio
sources with line-level signals to the XP1000. You can connect the outputs from
acoustic guitar active pickups, keyboards, drum machines, CD/MP3/TAPE players
and other units with line level outputs here.
2. USB WIRELESS Input* – Connect the optional Samson Stage XPD1 digital wireless
USB receiver to this input. The wireless receiver gets its power from the XP1000,
so no additional power supply is needed. The WIRELESS input is routed to the
channel 4 LEVEL control.
3. MIC/LINE switch (channels 1 - 4) -The MIC position changes the gain of both input
jacks to MIC level. The LINE position reduces the gain of both jacks by 26dB to
line level.
4. LIMIT/COMP switch - Set the LIMIT/COMP switch to the COMP position to apply
compression or set it to the LIMIT position to apply limiting.
Compressors are used to control the dynamic range of a signal, which offers
a variety of benefits including leveling a signal and increasing the loudness
of a sound system to name.
A Limiter is a specific form of a compressor configured to prevent peaks and for
general overload protection.
* The USB connector is for the Stage XPD1 receiver only. The connector is not designed
to charge smartphones, tablets, or similar devices.

5. Equalizer control knobs
HIGH Frequency – The HIGH knob controls the amount of treble applied to each
channel. The channel’s high frequency response is flat when the knob is in the cen-
ter detent (12:00) position. Rotating the knob to the right will boost the channel’s
high frequency response above 10 kHz by 15 dB, and rotating it towards the left
will cut the high frequency response by 15 dB.
LOW Frequency – The LOW knob controls the amount of bass applied to each chan-
nel. The channel’s low frequency response is flat when the knob is in the center
detent (12:00) position. Rotating the knob to the right will boost the channel’s low
frequency response below 100 Hz by 15 dB, and rotating it towards the left will cut
the low frequency response by 15 dB.
6. EFFECTS switch - Use the EFFECTS switch to add an effect to a Mic or Line input on
any of the first four input channels. The EFFECTS indicator lights GREEN when the
channel EFFECTS switch is ON.
7. LEVEL knobs - This knob sets the overall level for the input channel.
NOTE: To reduce noise, set the LEVEL controls on any unused channels to the mini-
mum setting.
8. Stereo Channel Input Jacks (channels 5/6, 7/8, 9/10) - For stereo inputs, use the L
input to connect the left channel and the R input to connect the right channel.
Use these inputs to connect high impedance microphones, synthesizers, drum
machines, MP3, CD, tape players or any other line level device. The XP1000 fea-
tures ¼” phone, ¹ / 8 ” phone, and RCA connectors.
9. MONITOR OUT jacks - The signal present at the MONITOR OUT jacks is sent from the
MONITOR level control knob, which is fed from the input channels. The MASTER
control does not affect the MONITOR OUT signal. This output can be used to send
the mix to powered speaker cabinets to use a stage monitors, or as additional front
of house speakers to expand the coverage of the system.
10. REC OUT jacks - This output is used to send the main mix to an external recorder.
The signal present at this connector is the L/R bus signal before it has passed
through the MASTER level control. The nominal output level is -10 dBV and the
impedance is 600 Ohms.
11. SPEAKER OUT jacks - Two ¼” phone powered output jacks used to connect the left
and right speakers. Use the included speaker cables to connect the speakers.
CAUTION: The total impedance load for each side of the amplifier must not be less
than 4 Ohms. Do not connect additional speakers to the XP1000 mixer/amplifier.
12. AC Input – Connect the supplied heavy-gauge 3-pin “IEC” power cable here.
13. POWER switch - Use the POWER switch to turn power to the XP1000 on or off. The
switch illuminates red when the unit is in the ON position and receiving power.

sent to the MONITOR OUT.
18. Effects Program (PROG) selector - This control knob is used to select one of 16,
24-bit DSP effects programs.
19. Effects SEND knob - The SEND knob is used to adjust the total amount of effects
added to any channel that has its EFFECTS switch (see #6) pressed down.
20. MASTER knob - The MASTER volume knob controls the overall output level. This
knob determines the final output signal level. Signals from all ten channels are
routed here just before being routed to the built-in power amplifiers and Left and
Right speaker output jacks (see #11).
21. METER LED indicators - This six-segment bar meter shows the XP1000’s output level.
For optimum signal-to-noise ratio, set the VOLUME control so that program material
is usually at or around +3 to +6 VU, with occasional, but not steady excursions to
the red “LIMITER” segment.
22. READY indicator - The indicator will illuminate when the power switch is turned on
and the unit is ready to pass audio.
23. PHANTOM switch - The XP1000 features an onboard phantom power supply to oper-
ate condenser microphones. When the switch is engaged, the LED will illuminate
indicating that phantom power is now available on the microphone pre-amps.
IMPORTANT NOTE: To avoid a loud pop, be sure to turn down the MASTER level
control before plugging and unplugging the mic cables when the phantom power is
active.

9. If you notice that the LIMITER indicator is lighting constantly, turn the MASTER
volume down so that the indicator only lights occasionally during loud hits.
10. To add depth to the mix or smooth out the vocals, you can apply effects such as
reverb to channels 1–4. To do this, press the EFFECTS button on the channel(s) to
which you would like to add the effect.
11. Slowly turn up the effects SEND knob until the desired sound is reached.
12. To alter the tonal characteristic of the signal, you can adjust the LOW
(bass) and HIGH (treble) controls. If you find the audio too muddy, you
may want to reduce the LOW control. If you find that the audio sounds
dull, you can increase the HIGH control. There is no right or wrong way
to EQ a sound. You should listen to how the mix sounds in the room and
fine-tune to your liking.

FRANÇAISDEUTSCHEESPAÑOLITALIANO
Applying Effects
The XP1000 features built-in, high quality, 24-bit digital effects that you can add to
channels 1 through 4. You can use effects like delay or reverb to enhance vocals or
ambiance to the mix by following the steps below:
1. Connect a mic or instrument to the desired channel, and adjust the volume and
equalizer to your liking.
2. Use the Reverb Program selector to choose one of the ten built-in digital effects.
3. Press the EFFECTS switch down on the chan-
nel to which you want to add the digital effect.
4. Once you have selected the channel(s) for effects by using the channel
EFFECTS switch, raise the effects SEND main level control to apply the
amount of effect desired.
Feedback is the annoying howling and squealing that can heard when the microphone
picks up sound from the speaker. The sound is then re-amplified back through the
speaker again, creating a feedback loop. Follow these steps to minimize the likelihood
of feedback:
• Avoid pointing the microphone directly at the speakers. In general it is
recommended that the microphone be positioned behind the speaker enclosure.
This uses the directional characteristics of the speaker and microphone to your
advantage.
• Keep the microphone as far from the speakers as possible. This will help achieve
isolation between the speaker and the microphone, and allow you to increase the
output of the XP10000.
• Position the microphone as close to the sound source as possible. This will
enable the microphone to pick up more direct sound, and allow you to reduce the
microphone input gain control.
• Reduce the MASTER LEVEL of the XP1000 system.
Avoiding Feedback
