Introduction 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.
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.

Setting Up and Using Your F1200 / F800 Setting up your F1200 / F800 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 three rack spaces.
The F1200 / F800 Protection Circuitry The F1200 / F800 Protection LED relay speaker connection circuitry is active when the amp[[lifier is powered on or off. When the circuitry is active, and all connected speakers are muted (provided with 0 volts DC), thus protecting them and preventing any audible “thump” from occurring.
Bridged Mode The F1200 / F800 provides a rear-panel switch that allows it to be used in either a Stereo or Bridged mode. When this switch is placed in the “STEREO” (right) position, the F1200 / F800 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.
F1200 / F800 Connections The illustrations below show the required interconnections when using the F1200 / F800 in Stereo or Bridged modes.
