Here's another great chance to own an ATI amplifier at a greatly reduced price!
Designed by legendary amplifier designer Morris Kessler, ATI’s 1800 series is our best single-ended lineup. Available with 2 to 7 channels, the 1800 series is conservatively rated at 180 watts RMS into 8 ohms from 20 Hz to 20 kHz with less than 0.03% THD and IMD and with 270 watts RMS into 4 ohms with the same conditions. Signal to noise ratio exceeds 120 dB at full rated output which is why audiophiles consider ATI amps to be dead silent during use. Based simply on measurements, we could easily have rated the amplifier at 210 watts RMS per channel at 8 ohms, but then, we are conservative.
All 1800 series amps have dual toroidal power transformers, 22,400 microfarads of capacitance per channel in the power supply and monoblock construction with everything except the transformer on a single PCB. Other features making it installer-friendly are: a detachable IEC power cord, optically coupled protection circuits, soft-start circuit and convection cooling eliminating the need for fans.
This 1805 model comes in ATI's RACK MOUNT CHASSIS and is considered to be "B" stock by Amplifier Technologies because it has minor cosmetic flaws. In any case the unit is electrically perfect and meets all performance specifications. Plus, and this is important, it carries the full manufacturer's 7-year warranty.
