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.

The high efficiency of the ED series enables maximum efficiency with low heat generation.
A new and unique Class-H circuity technology using state of the art SMD Surface Mount Technology with a reduced number of components offering performance levels exceeding audiophile levels like a slew rate of 50V/µs and high-end extended dynamic sound. The 2U amplifier provides 2x550W into 4 Ohm is equipped complete with temperature-controlled fan cooling, all common protective circuits such as over-temperature, short circuit, RFI and soft start.
The integral soft clip limiter protects against damage to the connected loudspeakers, the activity of a protective circuit, signal and limiter are shown for each channel by LEDʼs.

COMPACT MODERN DESIGN
Compact size (2U-Rack Height) with up to 1200W per channel@2ohms
these amps save valuable rack space without compromising power output.
HIGH CURRENT TOROIDAL TRANSFORMER
A high-current toroidal transformer saves rack space
and minimizes hum and noise.
EXCELLENT SOUND QUALITY
The low T.H.D.(0.05%) and high damping factor (400 or higher)
gives excellent sound quality.
2 STAGE POWER SUPPLY
The high-power units (L1800 and L2400) have a 2-Stage Class-H design
that maximizes their performance.
EQUIPPED WITH 30Hz or 50Hz HPF
All amplifiers are equipped with high-pass filters on each channel to
help maintain sound quality, yet help protect the loudspeakers.
EXTENSIVE PROTECTION CIRCUITS
Extensive protection circuits monitor over voltage/current conditions, overheating,
output shorts, and DC voltage to improve performance and reliability.
CLIP-LIMITER CIRCUITS
Clip-limiters on each channel are provided to help prevent
distortion due to excessive signal levels.
