The P-1800 AR provides consistent 120-V output (±5 V) from input voltages ranging from 97 VAC to 137 VAC. Unlike commercial voltage regulators, the P-1800 AR's new True RMS voltage regulation technology, featuring an ultra-low-noise, microprocessor-controlled eight-tap toroidal autoformer, is engineered for use in any A/V environment.
The benefit of True RMS is the assurance of quiet operation for critical listening and recording applications, with minimal leakage of stray magnetic fields. Additionally, when the autoformer switches voltage taps at the zero cross points of both voltage and current, it does not inject noise into the audio signal, thus providing stable voltage when subjected to severe voltage fluctuations - even when connected to power generators.
