reinforcement power amplifiers around, and we want to tell you about it! So, before you plug in, we’d like
to suggest you take just a few moments out to scan these pages. We’ll make it as painless as possible,
we promise—and, who knows, you might just pick up a tip or two.
The Samson S1500 / S2000 is a three rack-space stereo power amplifier which is optimized for live
sound venues, commercial installations, and for driving medium and large-sized PA systems.
Fan-cooled for maximum thermal protection, the S1500 delivers 750 watts of power per channel
(or, in Bridged mode, 1500 watts), and the S2000 provides a whopping 1000 watts of power per
channel (or, in Bridged mode, 2000 watts), over the full frequency spectrum, from 10 Hz to 55 kHz.
Combination connectors allow both balanced XLR and balanced 1/4" TRS input connections; output
connections are provided on both standard banana and advanced Speakon™ connectors.
Front-panel controls and displays include a power switch and LED, as well as independent left- and
right-channel input level controls, three-segment LED meters, and Protection LEDs.

S1500 / S2000 Features
The Samson S1500 / S2000 power amplifier utilizes the latest technology in professional power amplifier
design. Here are some of its main features:
• Power to spare - In the S1500, each channel delivers 750 watts of power into 4 ohms. In the S2000,
each channel delivers 1000 watts of power into 4 ohms.
• A Bridged mode links both channels, thus providing additional power (1500 watts into 8 ohms in the
case of the S1500; 2000 watts into 8 ohms in the case of the S2000).
• XLR link outputs, allowing multiple amplifiers to be “daisy-chained” together for even
more power.
Plus, the utilization of advanced circuitry and direct wiring ensures that there is no distortion in slaved
amplifiers even when the first amp in the daisy-chain is powered off.
• Clean, crisp sound - Impressive audio specifications such as 0.04% THD, dynamic range of greater
than 100 dB, crosstalk of 78 dB, and frequency response of 10 Hz to 20 kHz guarantee ultra-clean
sound quality.
• Independent 41-position detented input level controls for each channel allow precision adjustments.
• Three-segment LED meters for each channel continuously display power output levels and allow you
to correct for overloading (clipping) conditions.
• Unique stable bipolar circuit design for long life and enhanced audio performance. The circuitry
continuously keeps DC output at or near 0 volts during idling. This serves to minimize heat overload
problems by effectively preventing the S1500 / S2000 from applying power when unnecessary.
• Dual temperature-sensitive speed-controlled fans for reliable cooling without thermal and overheating
problems.
• Protection relay circuitry (with dedicated LEDs for each channel) that guards against overheating or
faulty wiring conditions and also prevents “thumps” when powering on or off. This means that you
can use the S1500 / S2000 with a single power strip into which a mixer or other audio devices are
connected, without danger of damage to connected speakers.
• Combination input connectors for each channel accommodate both balanced XLR or balanced 1/4"
TRS plugs, as well as both Speakon™ and banana jack output connectors for maximum flexibility.
• Toroidal transformer power supply for high current and low profile.
• User-resettable circuit breaker for fast, easy startup following a power supply overload.
• Supplied user-installable PowerCon™ connector power receptacle.
• The S1500 / S2000 can be mounted in any standard 19" rack (taking just three rack spaces), making
it easy to integrate the into any fixed or traveling PA rig.
• Rugged construction (an all-steel chassis with a titanium finish and a lightweight anodized aluminum
heat sink) makes the S1500 / S2000 eminently roadworthy.
• Three-year warranty.
• Last but certainly not least, value. The Samson S1500 / S2000 has been designed from the ground
up to deliver excellent yet affordable sound quality.
Guided Tour - Front Panel
1: Power switch - Use this to power the S1500 / S2000 on or off.
2: Power LED - Lights whenever the S1500 / S2000 is powered on.
3: Protection LED - This goes on for approximately five seconds whenever the S1500 / S2000 is
powered on and then turns off (you’ll hear a “click” when it does so). The Protection LED will also light
when overheating or other severe problems occur (see page 6 in this manual for more information). It is
normal for the Protection LED to fade slowly when the amp is powered off. When lit, 0 volts DC are
provided to all connected speakers, thus muting them and preventing any “thump” from occurring. For a
complete description of the conditions under which this light goes on, see the section entitled “The S1500
/ S2000 Protection Circuitry” on page 6 of this manual.
4: Channel input level controls - These 41-position detented knobs allow you to precisely adjust the
input level of the signal arriving at the rear-panel input jacks (see #7 on the following page). At their fully
counterclockwise position (labeled “-80 dB”), the signal is attenuated by 80 dB (essentially completely
off). At their fully clockwise position (labeled “0 dB”), the signal is at unity gain (that is, no attenuation).
When 0 dBu of signal arrives at the input jacks and the Channel input level controls are set to their fully
clockwise “0 dB” position, the S1500 / S2000 delivers full power output.
5: LED meters - These three-segment LED meters continuously monitor the power output level for the
corresponding channel. For convenience, the segments are labeled, from left to right, -40 dB, -20 dB,
and CLIP. The left (-40 dB) segment lights whenever input signal is present. The right (CLIP) segment
lights whenever the channel is outputting signal at full strength. For the best signal-to-noise ratio, the
right (CLIP) segment should light occasionally during peak levels; if it lights frequently, you may be
overloading the S1500 / S2000 and a distorted (“clipped”) signal is probably being output. If this occurs
and backing off the Input Level control delivers too low an output level for your application, consider
using Bridged mode (see the “Bridged and Parallel Modes” section on page 7 in this manual for more
information).

Guided Tour - Rear Panel
1: Fan - This variable-speed fan provides vital cooling to your S1500 / S2000 (the hotter the amp gets,
the faster the fan blows!). Make sure that both the front and rear panels are kept free of all obstructions
and that cool, fresh air is accessible at all times. Also, try to ensure that the S1500 / S2000 is used in a
dust-free environment.
2: Circuit Breaker - This circuit breaker will trip if there is a fault with the mains voltage or if maximum
output is exceeded (very highly distorted). Push it in (once only!) to restart the amplifier.
3: AC input - Connect the supplied heavy-gauge 3-pin “IEC” power cable here. Alternatively, the
supplied PowerCon™ connector plate can be attached here.
4: Banana output connectors - Use these to connect each channel of the S1500 / S2000 to 4- or 8ohm loudspeakers. Be sure to connect the loudspeaker correctly, with the red (+) terminal normally
connected to the positive input of the speaker and the black (ground) terminal normally connected to the
negative input of the speaker. See page 7 in this manual for more information about Bridged mode and
pages 8 and 9 in this manual for full speaker connection instructions.
5: Speakon™ output connectors - Alternatively, you can use these to connect each channel of the
S1500 / S2000 to 4- or 8-ohm loudspeakers. See page 7 for more information about Bridged mode and
pages 8 and 9 for full Speakon™ connector wiring and interconnection instructions.
6: Bridged / Stereo / Parallel switch - For normal operation, place this three-way switch in its center
(“STEREO”) position. When placed in its right (“PARALLEL”) position, the signal arriving at the
Channel 1 input only is routed to the power amplifiers of both Channel 1 and Channel 2 (the Channel 2
input is ignored), with each power amplifier delivering 750 watts into 4 ohms (in the case of the S1500)
or 1000 watts into 4 ohms (in the case of the S2000). When placed in its left (“BRIDGED”) position, the
signal arriving at the Channel 1 input only is again routed to both power amplifiers (again, the Channel 2
input is ignored), but the two power amplifiers are bridged together, providing 1500 watts of power into
8 ohms (in the case of the S1500) or a full 2000 watts of power into 8 ohms (in the case of the S2000).
For more information, see the “Bridged and Parallel Modes” section on page 7 and the “S1500 / S2000
Connections” section on pages 8 -9.
WARNING: Due to the extremely high power output of the
S1500 / S2000 when used in Bridged mode, be sure to use only loudspeakers sufficiently rated to
handle the resultant wattage (in Bridged mode, these must be 8-ohm speakers).
7: Input connectors
- Connect incoming signal to these electronically balanced Combination
connectors, using either XLR or 1/4" TRS (Tip/Ring/Sleeve) plugs, wired as follows: Pin 2 (or Tip) hot,
Pin 3 (or Ring) cold, and Pin 1 (or Sleeve) ground. We recommend the use of balanced three-conductor
cabling wherever possible (unbalanced two-conductor 1/4" plugs can also be inserted into these inputs,
but you’ll get better signal quality and less outside noise and hum if you use balanced lines).
The S1500 / S2000 accepts input levels of any strength but needs at least 0 dBu to achieve maximum
power. Stereo signals should be connected to both the Channel 1 and Channel 2 input jacks; however,
when operating the S1500 / S2000 in Bridged or Parallel modes, use the Channel 1 input jack only.
See page 7 in this manual for more information about Parallel mode and pages 8 and 9 in this manual
for full interconnection instructions.
8: Link connectors - These XLR connectors provide unity gain outputs, allowing the S1500 / S2000 to
be daisy-chained to additional power amplifiers. Wiring is as follows: Pin 2 hot, Pin 3 cold, Pin 1 ground.
See page 9 in this manual for more information.

Setting Up and Using Your S1500 / S2000
Setting up your S1500 / S2000 is a simple procedure which takes only a few minutes:
1. Remove all packing materials (save them in case of need for future service) and
decide where the amplifier is to be physically placed—it can be used free-standing or
mounted in a standard 19" rack, requiring only three rack spaces. When installed, make
sure that both the front and rear panels are unobstructed and that there is good
ventilation around the entire unit (we recommend the use of spacer panels, especially if
multiple amplifiers are used in a rack. If required, the supplied alternate PowerCon™
power receptacle should be installed in place of the IEC receptacle at this time.
2. Set the rear panel Bridged / Stereo / Parallel switch as desired (see the “Bridged and
Parallel Modes” section on page 7 in this manual for more information). If desired, use
the XLR Link connectors to “daisy-chain” the output of the S1500 / S2000 to external
amplifiers (see #8 on page 4 in this manual for more information).
3. Make the speaker connections, using the banana or Speakon™ output connectors on
the rear panel. It is never a good idea to power up any amplifier that is not connected to
loudspeakers. When operating in Stereo or Parallel mode, any loudspeakers with a
minimum impedance load of 4 ohms (that is, 4 ohms or greater) can be used; however,
in Bridged mode, 8 ohm speakers
must be used. Be sure to connect the loudspeaker
correctly. In Stereo or Parallel mode, make sure the red (+) terminal is connected to the
positive input of the speaker and the black (ground) terminal is connected to the negative
input of the speaker. See page 7 in this manual for more information about Bridged mode
and pages 8 - 9 in this manual for full speaker interconnection instructions.
4. Next, make the signal input connections, using the Combination input connectors on
the rear panel (if operating the S1500 / S2000 in Bridged or Parallel mode, use the
Channel 1 input only—see page 7 in this manual for more information). If your mixer or
crossover network has balanced outputs, we recommend the use of three-conductor
cabling and connectors (unbalanced two-conductor plugs can also be inserted into the
Combo inputs, but you’ll get better signal quality and less outside noise and hum if you
use balanced lines).
5. On the front panel of the S1500 / S2000, turn both Channel input controls fully
counterclockwise (to their “-80” setting). Then connect the supplied heavy-gauge 3-pin
“IEC” cable (or, if the alternate power receptacle is installed, a PowerCon™ cable) to the
rear panel power receptacle and to any grounded AC socket. Because of the relay protection circuitry built into the S1500 / S2000, you can even plug it into the same power
strip that other audio devices (such as a mixing console) are connected to. You can then
turn on all devices at once with the single power strip on-off switch, with no danger of
damaging connected speakers by generating “thumps.”
6. Press the front panel Power switch in order to turn on the S1500 / S2000. The Power
LED will light and the Protection LED will go on. After approximately five seconds, the
Protection LED will go off (you’ll hear a click when this occurs).
7. Apply an input signal to the S1500 / S2000 at or about 0 dBu (if sending signal from a
mixer, drive the output meters at approximately 0 vu). While the input signal is present,
slowly raise the Channel Input controls until the desired sound level is achieved.
The three-segment LED meters next to each Channel input control will show you the
continuous power output of the S1500 / S2000 as signal is being passed. For the best
signal-to-noise ratio, the S1500 / S2000 should normally be run with the Channel Input
controls at or near maximum (fully clockwise, at the “0 dB” position) and the right (CLIP)
segment should light occasionally (but not frequently) during peak levels. If you are
using a mixer that has a master output level control (sometimes called “control room
level”), use it to attenuate the signal as necessary to achieve the desired speaker level.
If you encounter difficulty with any aspect of setting up or using your S1500 or S2000,
contact your local Samson dealer. If purchased in the United States, you can call
Samson Technical Support (1-800-372-6766) between 9 AM and 5 PM EST.

The S1500 / S2000 Protection Circuitry
As noted in the “Guided Tour” section of this manual, the S1500 / S2000 frontpanel Protection LED indicates the activity of the relay speaker connection
circuitry. When the Protection LED is lit, this circuitry is active, and all connected
speakers are muted (provided with 0 volts DC), thus protecting them and
preventing any audible “thump” from occurring.
The following conditions will cause the Protection LED to go on:
•
Initial power-up: For approximately five seconds after initial power-up, the
protection circuitry is activated and the speaker output is muted. If everything is
operating normally, you will hear an audible click at the conclusion of this brief
period, as the protection circuitry is deactivated and the S1500 / S2000 begins
delivering signal to connected speakers (at which point you’ll hear a click). It is
normal for the Protection LED to fade gradually after the amplifier is powered off.
•
Overheating: A temperature sensing device in the S1500 / S2000 will cause
the protection circuitry to be activated (and the Protection LED to go on)
whenever the operating temperature of the unit rises above a safe level. To
guard against this problem, make sure the S1500 / S2000 receives adequate
ventilation on all sides and that both the front and rear panels are unobstructed.
•
Severe overcurrent conditions: This occurs whenever the signal being input to
the S1500 / S2000 rises to a level above 20% THD (Total Harmonic Distortion).
•
Shorted speaker cables: This will occur if, due to faulty wiring, the hot and
ground signals being output by the S1500 / S2000 short one another.
•
Output impedance drops below 2 ohms: This can occur if the S1500 / S2000
is connected to inappropriate speaker systems (see the “Setting Up and Using
Your S1500 / S2000” section on page 5 in this manual for more information).
•
DC voltage detected at speaker output: The most likely cause of this is an
internal failure.
In general, any time the Protection LED lights up (other than during the
approximately five seconds following initial power-up), there is reason to be
concerned. If this occurs, turn the S1500 / S2000 off immediately and carefully
check all wiring and external devices in order to locate and correct the condition
that caused the LED to light up in the first place.
For further assistance, contact your local Samson dealer. If purchased in the
United States, you can call Samson Technical Support (1-800-372-6766)
between 9 AM and 5 PM EST.
WARNING: If the Protection LED fails to go out (and you fail to hear the
accompanying audible click) approximately five seconds after power-up,
turn the S1500 / S2000 off immediately and check all external devices and
wiring for possible shorts or other defects.

Bridged and Parallel Modes
The S1500 / S2000 provides a rear-panel switch that allows it to be used in
either a Bridged or Parallel mode. When this switch is placed in the “STEREO”
(center) position, the S1500 / S2000 functions as a true stereo amplifier, where
both of the two independent amplifier channels (Channel 1 and Channel 2) can
receive different input signals and produce independent output signals.
However, when the switch is placed in the “BRIDGED” (left) position, the
Channel 1 inputs signal is routed to both power amplifiers bridged together,
producing a single output signal with a true 1500 watt output into a single 8 ohm
channel (in the case of the S1500) or a true 2000 watt output into a single 8 ohm
channel (in the case of the S2000).
The illustration on the right shows how this works. In Bridged mode, the
polarity (phase) of the Channel 2 output signal is reversed relative to that of
the Channel 1 output signal. Both channels then process the same input
signal, with the speaker load connected so that power is derived from both
channels. The effective voltage swing seen by the load is thus doubled, so
that the power output is doubled.
When using the S1500 / S2000 in Bridged mode, be sure to connect your
loudspeaker as shown in the illustrations on page 9 (and as silkscreened on
the rear panel), with the red (+) terminal of the Channel 2 output connected to
the negative input of the speaker and the red (+) terminal of the Channel 1
output connected to the positive input of the speaker.
Do not use the black
ground (-) output terminal of either channel (the speaker load must
“float” away from the amplifier chassis).
When the rear panel switch is placed in the right “PARALLEL” position, the
S1500 / S2000 operates in a unique Parallel mode. In this mode, only the signal
present at the Channel 1 input is used (and only the Channel 1 input control is
functional). This signal is then routed to both the Channel 1 and Channel 2
power amplifiers, thus producing a dual mono output, with 750 watts per channel
into 4 ohms (in the case of the S1500) or 1000 watts per channel into 4 ohms (in
the case of the S2000).
See pages 8 - 9 in this manual for interconnection diagrams when using the
S1500 / S2000 in Bridged or Parallel modes
WARNING: Bridged mode is to be used only when the S1500 / S2000 is
connected to an 8 ohm speaker load. Use of Bridged mode with speaker
loads of 4 ohms or less can result in severe damage to the unit due to
excessive heat and current limiting and will void your warranty!
