In full working condition. Retails for US$ The Samson SX stereo power amplifier has been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by professional audio engineers and installersThe 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.The SX is the most powerful addition in the SX series of amplifiers. Boasting a staggering Watts of Class H power in a two rack space design. The SX is a perfect solution for driving professional audio systems of any size. The SX Amps are built around a new power core design with over-sized toroidal transformers and extra-large heat sinks. The amps maintain cool operating temperatures thanks to an innovative forced-air cooling system with temperature sensitive variable-speed fans.Trouble free operation is provided by multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage, assuring total reliability under the most demanding conditions. The entire SX line is 2 Ohms stable and features locking XLR/TRS inputs, Speakon® and 5-way binding post speaker outputs.Features:• Professional High Power Rail-switching Amplifier• 800 Watts per side @ 8 Ohms• Watts per side @ 4 Ohms• Watts bridged mono @ 4 Ohms• Dual Variable-speed Fan Cooling• Signal, Peak, and Protection Circuit Indicators• 5-way Binding Post and Speakon™ Speaker Outputs• XLR and TRS Input Connections• Dual Rack Space DesignHighlights:• Clean, crisp sound - Impressive audio specifications such as 0.04% THD, dynamic range of 105 dB, crosstalk of 80 dB, and frequency response of 10 Hz to 55 kHz guarantee ultra-clean sound quality.• Independent input level controls for each channel allow precision adjustments.• LED signal indicators for each channel continuously display power output levels and allow you to correct for overloading (clipping) conditions.• Unique stable bipolar circuit design that continuously keeps DC output during idling at or near zero volts (thus keeping idle speakers at their zero point). This serves to minimize heat overload problems by effectively preventing the SX Series from applying power when unnecessary.• Forced air cooling via two temperature-sensitive, variable speed fans provides reliable performance 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 SX Series 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-inch TRS plugs.• Output connections are made via 5-way binding posts and Speakon™ connectors.• Toroidal transformer power supply for high current and low profile.• User-resettable circuit breaker for fast, easy startup following a power supply overload.• The SX Series can be mounted in any standard 19" rack (taking just two rack spaces), making it easy to integrate the amp into any fixed or traveling PA rig.• Rugged construction (an all-steel chassis with a cool gray finish and a lightweight anodized aluminum heat sink) makes the SX Series eminently roadworthy.• Last but certainly not least, value. The Samson SX Series has been designed from the ground up to deliver excellent sound.
