Thank you for purchasing the Samson F1200 / F800 Power Amplifier. The Samson F1200 / F800 is a
three-space stereo power amplifier which is optimized for live sound venues, commercial installations, DJ
set-ups and for driving small and medium-sized PA systems. Fan-cooled for maximum thermal protection, the F1200 delivers 600 watts of power per channel (or, in Bridged mode, 1200 watts), and the F800
provides 400 watts of power per channel (or, in Bridged mode, 800 watts), over the full frequency spectrum, from 20 Hz to 20 kHz. Combination connectors allow both 1/4" and RCA input connections; output
connections are provided on a combination banana plug and bare wire terminal connectors. The front
panel includes a Power switch and Power, dual channel Peak and Bridge LEDs.
In these pages, you’ll find a detailed description of the features of the F1200 / F800 power amplifier, 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

F1200 / F800 Features
The Samson F1200 / F800 power amplifier utilizes the latest technology in professional power amplifier
design. Here are some of its main features:
• The F1200 delivers 600 watts of power per channel into 4 ohms. In the F800 delivers 400 watts of
power per channel into 4 ohms.
• In Bridged mode (linking both channels) the F1200 provides 1200 watts into 8 ohms and the F800
provides 800 watts into 8 ohms.
• Clean, crisp sound - Impressive audio specifications such as 0.05% THD+N (typ), dynamic range of
<100 dB, crosstalk of 65 dB, and frequency response of 20 Hz to 20 kHz guarantee ultra-clean
sound quality.
• Unique stable bipolar circuit design that continuously keeps DC output during idling at or near 0 volts
(thus keeping idle speakers at their 0 point).
• Forced air cooled by and internal fan, for reliable cooling without thermal and overheating problems.
• Protection relay circuitry that guards against overheating or faulty wiring conditions and also prevents
“thumps” when powering on or off. This means that you can use the F1200 / F800 with a single
power strip into which a mixer or other audio devices are connected, without danger of damage to
connected speakers.
• Input connectors for each channel accommodate both balanced 1/4" TRS and RCA plugs, and combination banana plug and shrouded binding posts for maximum flexibility.
• User-resettable circuit breaker for fast, easy startup following a power supply overload.
• The F1200 / F8000 can be mounted in any standard 19" rack (taking 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 F1200 / F800 eminently roadworthy.
• Three-year warranty.

Controls and Functions
1: Power switch - Use this to power the F1200 / F800 on or off.
2: Power LED - Lights whenever the F1200 / F800 is powered on.
3: Peak LED (Ch1 Ch2) - The Channel 1 and Channel 2 Peak LEDs light whenever the input signal is
about to clip. This is not a problem if the Peak LEDs should light occasionally during peak levels, but if it
lights frequently, you may be overloading the F1200 / F800 and a distorted (“clipped”) signal is probably
being output. If this occurs back off the Output Level control of the device connected to the input of the
F1200 / F800 until the LEDs light only occasionally.
4: Bridge LED - This LED lights when the F1200 / F800 is in Bridged mode.
5: Air Intake Vents - These vents and the vents on the sides of the F1200 / F800 allow air to be drawn
over the heat sinks by the internal fan. This keeps the amplifier from over heating. Never block these
vents when the amplifier is on. Remove any dust that may build up on the protective screen.
