ATI at4007
ATI AT4000 SIGNATURE SERIES The AT4000 series amplifiers, available with 2 to 7 channels, share the design philosophy and circuit sophistication of ATI's award-winning AT6000 Series amps at a reduced power of 200W RMS per channel at 8 ohms and 300W RMS at 4 ohms. Furthermore, their “signature series” designation with a facsimile of Kessler's signature on the main panel attests the special nature of these amplifiers. The use of a modular PCB layout with amplifier and power supply parts on the same card with edge to edge isolation of AC and signal input provides improved signal-to-noise ratio. Dual toroidal transformers, dual power switches and dual AC power cords bring a complete dual-mono design to the AT4002 and AT6002. Multi-channel amplifiers up to the 7-channel AT4007 and AT6007 models may be connected to independent 20 amp circuits for greater sustained output power than would be possible than from a single AC circuit. 4000 Series amps are rated at 200 Watts RMS from 20Hz to 20kHz with no more than 0.03% THD at 8 ohms with all channels driven and 300 Watts RMS at 4 ohms under the same conditions. Signal-to-noise ratio is typically -126dB referenced to full output so that each Signature Series amp is capable of playing back the full dynamic range available on today's lossless recordings.
