| SAMSON SX1200
PROFESSIONAL POWER AMPLIFIER
The Samson SX Series stereo power amplifiers have been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by the most professional audio engineers and installers. Their convenient 2 rack-space design is compact, and yet there’s plenty of power available, with 2 x 300 Watts at 8Ω, 2 x 450 Watts at 4Ω. That power rating is over the full frequency spectrum, from 10 Hz to 55 kHz, which helps give the SX amps their natural and open sound quality. For mono applications, a Bridge mode links both channels of the amplifiers, thus providing even more power, with power ratings of 900 watts into an 8 ohm load.
Input connections are made via Combination connectors allowing for both balanced XLR and balanced 1/4” TRS connections. For the outputs, the SX series amplifiers provide standard 5-way binding posts, as well as a Speakon™connectors. Front-panel controls and displays include a power switch with LED indicator, as well as independent left and right channel input level controls. To help you set the correct operating levels, the SX amplifiers include front panel Signal, Peak and Protection LED indicators. Like all serious power amplifiers, the SX Series internal electronics are based around a serious power-core, with over-sized toroid al transformers and large extruded heat sinks.
To keep the SX amplifiers running cool, their designs employ twin internal wind tunnels with forced-air cooling via two temperature-sensitive, variable speed fans, which greatly reduces the chance of thermal and overheating problems. Multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage, assures high reliability under the most demanding situations. The SX amps are road tough with their all steel chassis, 19-inch rack mount design and convenient carry handles, the SX amplifiers are ready for a life of travel, or to make home in a nice fixed installation. Optimized for live sound venues, houses of worship, commercial installations, and for driving small and medium-sized live PA systems, the SX amplifiers will deliver reliable power from gig-to-gig, venue-to-venue and day-to-night.
