* power ratings are continuous (rms) with less than 0.5% THD, from 20-20,000 Hz.

†not applicable, since continuous current requirements exceed available AC mains service.

It is important to understand that these are worst-case requirements under severe test conditions, which are extremely unlikely to be encountered in normal use. The power demands that a single Nº33 might conceivably make when being used to reproduce music with actual loudspeakers are substantially lower, safely within the normal abilities of 100V and 120V, 15 ampere lines. Still, for the best possible performance with extremely difficult loads, we recommend installing a dedicated AC line for each amplifier of at least 200-volt and 30-ampere capability.

The operating voltage of the Nº33 cannot be changed by the user, and any at- tempt to do so will void the warranty. If you need to change the operating volt- age of your Nº33 power amplifiers, or if the voltage indicated on the rear panel label is not available in your area, contact your Mark Levinson dealer for assis- tance.
