SAMSON SX1800 Ενισχυτής Ισχύος 2X600W

The SX-1800 produces 1800 Watts of power from a class AB amplifier design.
Stable at 2 Ohms like the entire SX line, the SX-1800 lets you run a system at
a blistering 900-Watts per-side in stereo mode with out breaking a sweat, thanks
to the internal amplifier design and variable-speed fan cooling.

This professional stereo power amplifier, working in class-H mode, provides 2x800W, at an efficiency of around 85%.

A passive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode. The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling.  The integral soft clip limiter protects against damage to the connected loudspeakers.  The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.

Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps.
